Understanding major dimensions and determinants that help in diffusion & adoption of product innovation: using AHP approach

In this global world, diffusion & adoption of new product innovation have become intricate and involves multifaceted process, as consumers demand a broad range of choices. So, this has generated enthusiasm among researchers and business practitioners while studying and implementing diffusion & adoption of product innovation. Even though diffusion & adoption is known as one of the most important processes of an innovation management, but the literature available in this area is highly fragmented. Therefore, in this paper, we attempt to develop a framework for diffusion & adoption, which helps in learning and understanding its dimensions and determinants from different perspectives. In this study, AHP has been used to analyse the relative importance and provide a ranking to the dimensions and determinants of product innovation. The findings of this study can help the management, product developers and market professionals in strategic planning and in setting their priorities when there is resource constraint. This study also helps in deciding and prioritising the dimensions and determinants that should be fuse during product development phase.


Background
Innovation has been referred as utilisation of thoughts, ideas, plans and concepts to make economic benefits (Akinboye, 2003). When connected to business administration, innovation is a process of being inventive, executing new strategies to sort out or run an organisation and produce enhanced results (Gates and Cooksey, 1998). In the innovation process, creativity and imagination prompt invention; the first presentation or usage of an invention will be innovation, which leads to adoption; adoption results from the diffusion process (Kumar, Kumar and Haleem, 2014).
Product innovation is a complex and multifaceted process which involves many influential factors not only at an individual level but also at organisational and institutional level. It starts with the design phase and ends with the successful adoption of aspect of diffusion and having a different perspective. The fundamental contribution comes from economics, sociology, anthropology, and marketing. Business experts have created different econometric models to clarify the diffusion of new products in the light of the past conduct of the consumers. Geroski (2000) says that business studies have embraced an extensive variety of unique research tools to clarify the customer behaviour. Social studies have been engaged to inspect the socio-consistent element and mental factors that impact the diffusion of innovation, and most of the anthropological studies are base on case studies of the diffusion of new creations, regulations and information. Now, multi-disciplinary research has been developed looking at the diffusion of educational, medicinal and other approaches to innovation. Research on diffusion tries to identify the variables that impact the rate and course of the adoption of innovation.

This study is to identify and prioritise the determinants that help in diffusion and adoption of product innovation. In this study, Analytical Hierarchy Process (AHP) approach has recommended for prioritising the determinants helping in diffusion & adoption of product innovation (Saaty, 1980). The remainder of this paper organised as follows. The state-of-the-art review of related literature covered as well as identified determinants are helping in diffusion and adoption of product innovation based on extensive literature review (Section 2). Section 3 discusses and explains the methodology of the research for the present work. The data analysis has done in Section 4. Discussion, finding and the managerial implication is provided in Section 5. Finally, Section 6 provides conclusions, unique contributions, limitations and the scope for future research.

Literature review
This section contains the literature on diffusion and adoption of product innovation. The explanation of four dimensions of diffusion & adoption which is given by Everett M Roger's book titled "Diffusion of innovation" that has more than 77,533 citations is provided. The related determinants/ sub-factors of these dimensions, which helps in diffusion and adoption of product innovation identified and described using literature review approach. Research gaps for this study have been further discussed.

Diffusion and adoption of product innovation
Rogers (2003, fifth edition) defines diffusion as "the process by which an innovation is communicated through certain channels over time among the members of a social system".
It is being identified sort of communication that deals with the spread of messages which are view as new thoughts or ideas. Nowadays, information technology (IT) as an example, the Internet and mobile phones which become a part of mass communications and a tool of diffusion. It is the "novelty" of an idea in the message of communication that gives diffusion its unique character. There is a lot of work going on in the area of diffusion & adoption, and the research status of diffusion and adoption is impressive. In the 1960s and 1970s, the aftereffects of diffusion studies have incorporated in textbooks of public relations, marketing, advertising, social psychology, consumer behaviour and their related areas.
Researches/academicians and practitioners have come together to view the diffusion of product innovation as a significant field of sociology. Numerous U.S. government organisations have a division assigned for diffusing new technologies to local government as well as to the public; examples are the National Institutes of Health, U.S. Department of Transportation, The U.S. Department of Agriculture, and the U.S. Department of Education. Some federal agencies support research on diffusion, for example, the National Science Foundation and various private organisations. Further, most business corporations have a marketing division that is the researcher of diffusing new product and statistical research activities that lead to diffusion to help the organisation's advertising endeavours. Since innovation is happening throughout the society and the application of diffusion & adoption theory is found in numerous spots. In this way, diffusion & adoption research has accomplished a prominent position today.

Identification of determinants helping in diffusion & adoption of product innovation
Literature review approach has used for identifying determinants helping in diffusion & adoption of product innovation. Initially, seventeen determinants helping in diffusion & adoption of product innovation. Further, these identified determinants have been categorised into four dimensions (Innovativeness, Communication channels, Time, and Social system). These identified four dimensions, and related determinants help in diffusion process and determine the success of product innovation have been discussing in detail in below section.

Innovativeness
Innovation is depicted as a thought, practice, or an object that is view as new by consumers. Numerous analysts concur that the primary success factor of diffusion of innovation is exclusiveness and uniqueness (Pham and Ho 2015;Montazemi and Qahri-Saremi 2015;Winer 2007;Kinnear and Bernhardt, 1990;Cooper 2001). Market analysts have frequently considered consumer acknowledgement of innovation in connection with product innovativeness (Garcia and Calantone, 2002).
Product innovativeness is often identified with the principal innovation qualities (i.e., relative advantage, trialability and compatibility) (Danneels and Kleinschmidtb, 2001). However, (Danneels and Kleinschmidtb, 2001) says that conceptualization of product innovativeness has yet to be establish empirically. There are different points of view in the contemporary customer conduct literature (e.g., Hoyer and MacInnis, 2008) typically see factor such as compatibility and trialability as customer learning necessities that impact the speed of diffusion, rather than measurements of innovativeness.
Such interrelated and complex relationships do not often empirically examine in connection to perceived innovativeness. Uniqueness or exclusiveness has been a critical analysis of product innovativeness and has offered as the primary dimension at times (Hoeffler & Keller, 2003;Rogers, 2003, Valente & Rogers, 1995Sanni et al., 2013;Schiffman & Kanuk, 2004a;2004b;Singh et al., 2012;Tidd, 2010;Tidd et al., 1997). So, this prompts a definition whereby the level of innovativeness is not a distinct development but rather equals to the degree of originality. The individual meetings with experts recommend that innovativeness is more than uniqueness.
Characteristics of innovativeness that determine success to product innovation and which increase its possibility of successful diffusion and adoption are identifies: Uniqueness (UQ) Innovation which is unique experience three to five times more success than the innovation which does not stand out (Cooper 2001). However, Hoffman (2005), Lamb et al. (2004), Baker, (1999 note that the changes in the product that already exist and not the unique and radical ones are less risky. Therefore, more chances of having a successful diffusion. In this regard, researchers such as Zikmund & D' Amico (1993); Kinnear et al. (1995); Winer (2007);Hoffman (2005); Cooper (2001) concur that product innovation achievement relies on upon the accomplishment of making a product that is unique when contrasted with competitors.
Relative advantage (RA) Relative advantage is the extent to which an innovation is seen superior to the other ideas, and it supersedes by specific users, measured in terms that matter to those users, as comfort, economic point of preference, satisfaction or social prestige. The more noteworthy the apparent relative advantage of a product, the quicker its rate of adoption is likely to be. There are no set parameters for what constitutes as "relative advantage". It relies on upon the specific observations and necessities of the consumers.
Compatibility (CB) This is the extent to which a product innovation is seen as predictable and consistent with the qualities, past experiences, and needs of the consumers. An innovation that is inconsistent with the specified conditions, guidelines or practices won't be adopted or received as fast as an innovation that is compatible Customization (CU) Pine andGilmore (1999a, 1999b, p. 76) characterise customization as "…producing in light of a specific desire of analysing user." The researchers like Duray (2000a); Pine andGilmore (1999a, 1999b); Anuar et al. (2014); Chiyangwa and Alexander (2016) said that it is significant to make the refinement in the varieties and customization. While customization takes a stab at satisfying individual user's needs, ranges include more choices from which the user can pick. "In most of the cases, the user doesn't need choices; they exactly want what they specified" (Pine andGilmore 1999a, 1999b, p. 76). Customization is planned to increase the value of an item since a customised product is well defined according to customer's needs. The client association is a vital issue; since user dictates what the venture needs to create. In many cases, product customization can happen ex-post after assembling by the retailer or the users themselves. Also, to roll out procedures adaptable a few improvements on the product development level are necessary. Truth be told, "[t]he idea of modularity is an essential building block in the assembling circumstances customarily thought to be adaptable" (Duray et al. 2000a, p. 610).
Trialability (TB) According to Vasseur and Kemp (2015); El-Gohary (2012); Seyal and Rahman (2003); Stockdale and Standing (2006); Moore and Benbasat (1991); Chiyangwa and Alexander (2016); Sabi et al. (2016); Pham and Ho (2015); Hameed et al. (2012a) said that "Trial-ability is the degree to which an innovation can be tried in a restricted premises." Innovations that can be attempted on the instalment arrangement are embraced quickly than innovations that are not tried. The individual trying-out of advancement is an approach to offer to intend to development, to discover how innovation works under one's particular conditions. This trial is a way to dissipate instability about the new ideas.

Social system (SS)
The diffusion of the new product usually takes place in the social setting frequently referred as a social system. Sometimes in the context of consumer behavior, the term market segment and target market may be used instead of the social system. Rogers (2003) characterised the social framework as "an arrangement of interrelated units occupied with joint critical thinking to achieve a typical objective" (p. 23). Since diffusion of product innovation happens in the social framework or system, it is impacted by the social structure of the social framework. He guaranteed that the nature of the social framework influences people's innovativeness, which is the primary standard for arranging adopters.
The studies on the social system of framework gave by Schiffman et al. (2004aSchiffman et al. ( , 2004b ;Bakanauskas, (2004) ;Baker, (2001);Hoffman (2005) express that the related factor of the social system that helps in the accomplishment of diffusion of product innovation relies on: Attitude towards the change in social system (TC) The social system is dynamic is nature which changes continuously with respect to time. So, there should be a positive attitude towards the change in the technology and the market.
Rational relationships among members of the social system (RR) A rational relationship is a logical relationship among the member of the social system which is based on the reasons and facts rather than on emotions. Many researchers who deal with the consumer behaviour advocate that the rationality among the consumer decide the successful adoption of a product but it's hard to measure it. Sometime users of social system/ target market are emotionally attached or biased towards the certain product.
Level of homogeneity (HL) Uniformity among the members of a social system is neglected by the researchers as a condition for diffusion but in fact, play a fundamental role for social system/ target market.
Nature and norms characteristic of the social system (NN) Norms are established behaviour patterns for the members of a social system which defines the consumer's compatibility with innovation.

Communication (CM)
Communication is neither transmission of message nor message itself. It is the mutually shared understanding, beginning with the receiver. Communication should be viable in an association. It is the essence of diffusion and adoption. Indeed, even the basic operation of on organisation can't be performed well without effective communication. It includes the steady stream of information and feedback is an essential part of it. Communication between individuals from the innovation execution group likewise expands the likelihood of fruitful selection of innovation, when colleagues always discuss and communicate about the course of the creation process, conceivable issues and methods for solving those problems. Outside the association, it is between the organisation, its accomplices and shareholders, its delegates and user. Determinants of communication that helps in diffusion and adoption are discussed below: Mode of communication (MC) Communication has advanced significantly from the times of manual typewriters, telegrams and window placards. According to the researchers, such as; Baker, (1995), Cooper, (1999), Cooper, (2005 Dahnil et al. (2014), Hameed, et al. (2012a, Gopalakrishnan and Bierly (2001) and so forth the newest trend in communication that aids in a diffusion of innovation is social media advertising. That is, the cautious utilisation of social media sites like Facebook, MySpace, YouTube and Twitter to draw the consumer in their trusted network. Buyers make online profiles and organisations make "fan pages" or Twitter accounts that user might "like" or associate with it. The second alternative is email; Internal organisation communication depends on email; in only an era, email has supplanted paper as the mode of communication. The website is additionally one of the options for Critical communication. A few organisations go beyond and utilise their website to host user discussion forums, reports, videos and to post blog Understandable communication (UC) The interesting point of understandable communication is that individuals will adequately comprehend the message. Consumers need to know how marketers can help them, yet they would not prefer to invest hours making sense of what marketers are attempting to tell them. Clear communication is additionally critical inside the organisation and with the suppliers as well. Only if staff and vendors comprehend messages, then only they will take care of the job effectively. Dahnil et al. (2014), Gopalakrishnan and Damanpour (1994), Hameed et al. (2012a) said that understandable communication is necessary to the success of any organisation. However, it is often left to care for itself in numerous organisations. Understandable and clear communication built trust, reputation, relationship with customers and credibility; and all of these build organisation.
Communication channel (CC) In an association, information flows in every direction i.e. backwards, forward, and sideways. This information alludes as communication.
Communication channels mean the way this information flows inside the association and with different organisations. Gopalakrishnan and Damanpour (1994), Dahnil et al. (2014), Anuar et al. (2014), Abed et al. (2015), Hameed et al. (2012a) said that if communication channel breakdown, it will prompt a wasteful and insufficient information flow. Employees are unconscious of what the organisation expects of them. They are clueless about what is happening in the organisation. This will make them suspicious of thought processes and any adjustments in the organization. Likewise, without compelling communication channel, employees become division oriented instead of organisation oriented, and this influence decision making and profitability in the working environment.
Communication network (CN) According to Roger (2003), communication network consists of individuals that are interconnected by information flow that follows a pattern which means communication networks helps to create a link in a social system. Communication networking is critical for diffusion because, in an efficient network, the flow of information is smooth and right which take less time.

Time (TM)
In research, the ruling conclusion is that time is the premise of the entire procedure of diffusion and adoption of product innovation. Schiffman et al., 2004aSchiffman et al., , 2004b research consumer behaviour for a division of adopters. Hoffman et al., 2005;Antonides et al., 1998;Zikmund et al., 1993;Solomon et al., 2002;Schiffman et al. 2004a, 2004band Lamb et al., 2004 assets of purchasing recurrence. Bakanauskas, 2004 measures adoption rate and all the researchers advocate that time is one of the major factors for diffusion and adoption.
Introduction timing (IT) Introduction timing is frequently a represent the moment of Make-or-Break for small and medium enterprises. Whether, it's a producer working through wholesale and retail outlets, or a retailer attempting to draw in the consumer to innovation. Compelling timing is necessary to pull in new customer and to optimise profit and revenue on innovations. (Klastorin and Tsai, 2004;Regibeau and Rockett, 1996;Srivastava and Lee, 2005;Tony Ke, Max Shen and Li, 2013). In a competitive business sector, the timing and planning of introduction are also influenced by the introduction timing of similar product which is launched by other competitive organisations.
First-mover attempts to pull eager purchasers. Other organisations incline toward a second-mover and wait until the business sector gets comfortable with the item and interest starts to develop. This technique secures against a negative response that may come from the item offered by the first-mover.
Product development cycle (PD) Johnson and Kirchain, 2011 said the article dealing with the assessment of product development is somewhat substantial and concentrates principally on the lead-time metric. Surprisingly, only a few researchers like Chiyangwa and Alexander (2016) and Hameed et al. (2012a) have additionally demonstrated the significance of product development lead-time or cycle as it identifies with product or project achievement.
Progressive Technology (PT) As the time changes, innovation makes obsolete to the existing ones. For example, a smartphone replaces many gadgets which can't even count like watches, telephone, camera, personal computers, banking, etc. Adoption rate (AR) Rogers and Shoemaker (1971) define the rate of adoption as "the relative speed with which an innovation adopted by members of a social system. This rate of adoption is usually measured by the length of time required for a certain percentage of the members of a system to adopt an innovation" (p.28). Anuar et al. (2014), Montazemi and Qahri-Saremi (2015), Gopalakrishnan and Damanpour (1994). Rogers and Shoemaker agree with Toffler (1970) and others that the rate of adoption of innovations is rapidly increasing over a specified period. For instance, they justify the need for their book with the opening statement that "the phenomenal rate at which innovations are invented, developed, and spread makes it important to look at how these new ideas affect (or fail to change) the existing social order (Rogers and Shoemaker 1971, p.1)." But, no evidence is presented to show that the rate of adoption is increasing. All these variables have complied in Table 1 with references.

Research gaps
Many past research hypotheses advocate that setbacks experienced during diffusion are more prominent than the delays experienced during creation or product development phase. Although it is already established that diffusion and adoption are one of the costliest phases of the innovation process, there is practically no exertion made to develop a framework for diffusion and adoption or learning and understanding its dimensions and determinants from different perspectives. There is no study which deals with the relative importance of diffusion & adoption dimensions and their correlation with the determinants i.e. in how much weightage these dimension and determinants influences diffusion and adoption of product innovation. Therefore, in this study, AHP is used to analyse the relative importance and provide the ranking to the dimensions and determinants of product innovation. This study helps management, product developers and market professionals in strategic planning and set their priorities when there is resource constraint. It also helps in deciding and prioritising the dimensions and determinants that should be incorporated during product development phase.

Methods
In this paper, we have taken the four dimensions given by Everett M Roger's book diffusion of innovation which has more than 77,533 citations and which is the second most cited book in social science. Researcher believes that the name of Everett Rogers is virtually synonymous with the study of the diffusion of innovations. The determinants/ sub-factors of dimensions are identified with the help of extensive literature review of most cited paper in the area of diffusion and adoption of innovation. After determining dimension and determinant, we have conducted a workshop in which we sought the opinion of experts on categorising determinants under four well-established dimensions. There are four experts from the management of MSMEs and three from academia. After establishing dimension and determinants, we have used AHP methodology with the help of expert suggestions. Utilisation of AHP methodology helps in accomplishing efficient diffusion and adoption of product innovation and uncovering their significance for the competitiveness of organisations. Zikmund & D' Amico (1993), Gopalakrishnan and Damanpour (1994), Kinnear et al. (1995), Lambkin (1998), Baker(1999), Cooper (2001)   AHP has been used for this study because of its benefits over other multi-criteria basic making (MCDM) tools, for example, ISM, DEMETEL, ELECTRE, TOPSIS, and ANP. ISM can give the following structure to the reliant variables required in the study yet neglects to examine the relative significance of the variables w.r.t. The objective. Henceforth, it distinguishes the course of the relationship of the variables yet at the same time neglects to perceive their weightage. Other MCDM tools like ELECTRE and TOPSIS has restricted acknowledgement among practitioners and researchers (Mathiyazhagan et al., 2013;Kumar et al., 2015aKumar et al., , 2015bKumar et al., , 2015cKumar et al., , 2015d. Another MCDM tool is ANP which requires a few comparison pair-wise matrices that add complexity to the study for expert members (Harputlugil et al., 2011) as compared with AHP (Mathiyazhagan et al., 2013).
Solving problem utilising AHP can be sorted into the following three broad steps: Step I: Conversion of decision problem into a hierarchical structure. In this step, a systematic hierarchical structure was first developed (as shown in Fig.  2) to facilitate the study.
A list of dimensions and determinants for efficient diffusion and adoption are selected through a literature review and a structured hierarchical framework was developed with the help of expert consultation.
Step II: Collection of information and construct a judgmental matrix This step includes the gathering of information from experts. The experts have examined the strength of dimensions in connection with another dimension positioned on the relative scales in a pair-wise comparison (Saaty, 2000;Saaty, 2008;Lewis et al., 2006). With the assistance of the expert's judgment, an arrangement of correlation matrices was built for all components in a level and then change individual correlation judgments into proportion scale estimations (Kannan et al., 2008).
Step III: Determination of needs by calculation of standardised weights.
A nine-point scale, as proposed by Saaty (2000) proposed, and is utilised to measure the inclinations. The CR can be figured out by utilising the following formula: Where the order of matrix is "n" and "RI" is known as random consistency index. RI values for matrices given in Table 2 Data analysis and results There are four main dimensions of diffusion and adoption of product innovation i.e. innovativeness, social system, communication and time. In this study, we have identified various determinants of each dimension. With the help of AHP approach, we have calculated local and global weight and then rank them accordingly Tables 3, 4, 5, 6 and 7 shows the local priority weights of different factors as generated to determine the relative importance of these dimensions and their determinants with respect to successful diffusion and adoption of product innovation. After that, rankings of the level-3and level-4 has been done from their global weights (priority percent with respect to the objective) and are represented in Table 8.
The results have been compiled as follows: From the AHP analysis, it is found out that time is the most critical dimension followed by communication, innovativeness and social system.
If considering innovativeness as a primary dimension, then the highest local weight is of compatibility followed by relative advantage. If considering a social system as the main dimension, then the highest local weight is of rational relationships followed by nature and norms.  If considering communication as a main dimension than the highest local weight is of understandable communication followed by mode of communication.
If considering time as a main dimension than the highest local weight is of progressive technology followed by adoption rate. When considering a global weight then progressive technology, Understandable communication, Adoption rate, Mode of Communication, Introduction timing, Compatibility, Communication channels, Nature & norms have relative higher weight than other determinants.

Result and discussion
Due to globalisation, there is a rapid technological change, shorter product life cycles, environment and social issues. Thus, organisation are under tremendous pressure to incorporate changes in their business practices. Confronted with a progressively evolving environment, organisation are now dependably concerned about new product development. This could bring a change ranging from slight to moderate to extensive or the continuum, or even result in absolutely new product offerings. In-spite, new product development gives a competitive advantage to the organisation, but it is also sensible to consider the future longevity of technologies. There two problems that faced by any product innovation organisation are, i) whether the altered/new product would be acknowledged by the consumer(s), and ii) how rapidly would the product be recognised by the consumers(s). While the first relates to what is alluded to as diffusion, the second relates to what is known as adoption. Dissemination and adoption were studied by many researchers like Kotler et al. (2003), Zikmund & D' Amico (1993), Baker (1999), Kinnear et al. (1995), Winer (2007), Tidd (2001), Cooper (2001) and Hoffman (2005) but the literature is highly fragmented and deals with only a few aspects of it. Although Roger's studies on diffusion and adoption have introduced us with four dimensions of diffusion and adoption. But Roger's studies do not give the information   In this study, we have developed an input and output model of diffusion and adoption using literature review that can be helpful for organisations in identifying the gaps, flow of information and resources between the desired and the current conditions of diffusion and adoption as well as in identifying the areas of improvements. Next, we have taken 4 dimensions of diffusion and adoption given by Rogers (2003) i.e. innovativeness, social system, communication and time which include all the broad aspect of diffusion and adoption. Then with the help of literature review, we have identified 17 determinants of these four dimensions that influence diffusion and adoption of product innovation, and they are compiled in tabular form. After that hierarchical model is developed and this hierarchical model of diffusion and adoption of product innovation can permit managers/ decision-makers to effectively watch the impact of the progressions in the upper levels of the criteria with respect to the lower levels changes. Then we are using AHP approach in which we have done a pair wise comparison of each dimension and their determinants and then calculate their local and global weights. According to calculated weight, local as well as global ranking has been done that shows the relative importance of each dimension and determinants. It will help decision-makers/managers to structure their issue by  concentrating on its contrasting aspect instead of concentrating on only one or two aspects. Results will be useful especially for SMEs that are experiencing different sorts of asset limitations, as it will help in figuring appropriate strategies for optimum utilisation of resources.

Managerial implications
Diffusion and adoption of an innovative product not only increases profit for an organization but also emphasise on consumer's demand. It's a unification of the economic as well as social objectives. Following are the managerial insights that emerge from this study and are given in Table 9.

Conclusions
It's already established that diffusion and adoption is one of the most critical stages of product innovation. So, this study proposed a comprehensive framework to identify dynamics of diffusion and adoption issues from four different perspectives, namely, innovativeness, social system, communication and time. In this study, we have identified 17 sub-factors of these four dimensions/ issues which are justified from the references of different studies as given in Table 1.
An AHP (MCDM technique) has been proposed in this study to recognise the relative significance of different dimensions and determinants that are important for the diffusion and adoption of product innovation. It is found that compatibility and relative advantage have higher weights when considering innovativeness, rational relationship and nature and norms have higher weight when considering the social system, understandable communication and mode of communication when considering communication, progressive technology and adoption rate have higher weight when considering time. When considering global weights then progressive technology, Understandable communication, Adoption rate, Mode of Communication, Introduction timing, Compatibility, Communication channels, Nature & Norms have relative higher weights than other determinants. Therefore, an organization should give priority to these determinants and aligned their objectives while considering these dimensions and determinants which help in overall diffusion and adoption of product innovation.

Limitations and scope for future research
Seventeen major determinants Critical in this study under four major dimensions; hence, more determinants can be considered in future research. These determinants will have regional biases. The experts were from northern India, and we assume that their opinion is valid for the industry. For further validation, statistical techniques could be used for these determinants. Also, AHP has the constraint of capturing vagueness which is associated with the judgments of experts. So, fuzzy AHP which can give an opportunity to the experts to express their experiences through natural language can also be considered in future studies.
