Nowadays, it becomes very important to know the level of institutionalization and as a result what improvements they can make for organizations. Though there are many conceptual studies of institutionalization in the literature, there is no study based on numerical methods that can provide a foresight about institutionalization. In this paper, a new model has been proposed by determining concepts that are effective on institutionalization from literature and expert opinions. Firstly, the relationships between the concepts are taken from the experts linguistically. Linguistic expressions are converted to numerical values using the center of gravity method (COG) used in fuzzy logic applications. Then, three different scenarios were investigated by using the Fuzzy Cognitive Maps (FCMs) algorithm and the future states of the concepts were determined and interpreted. In the first scenario, an organization with poorly managed organizational concepts was considered. The institutionalization tendency in this organization has reached to 0,027 value which is the estimation calculated by FCM algorithm in the future. The second scenario and the third scenario represents a midlevel and good organization respectively. Institutionalization tendency values were 0.97 for the second and third scenarios. However, when the number of iterations representing the time period is examined, it is seen that the organization thought in the third scenario has reached this value before 9 iterations. This is because the organization in the third scenario is well managed in the current situation. With the developed model, the most effective concepts on institutionalization were also identified. It has been determined that the most important concepts affecting institutionalization are process management, information management and strategic management. Compared to the literature, the results seem to be consistent.

“…Fuzzy logic offers a useful approach when modeling application domains requiring the incorporation of subjective information and significant uncertainties [14]. This approach is already used for software cost estimation, when solving the software effort estimation problem [15], or to make decisions in information security management for softwaredefined networks.…”

The software development process (SDP) is complex because it uses specific knowledge, skills, tools, and techniques to deliver value to people, and the user’s needs are always growing and becoming more complex. Practitioners and academics have proposed different approaches for improving the successful implementation of the SDP. This remains a non-trivial task, and the number of successful software development projects increases only slightly each year. This paper proposes a new approach for adapting the classical SDP to a dynamic, knowledge-intensive, and context-dependent model by applying the case-handling and fuzzy inference approaches for SDP modeling and simulation. The advantages and novelties of this approach consist in: SDP dynamicity modeling using the case-handling approach; the inclusion of human factor uncertainty into the execution of SDP activities through fuzzification; and agent-based simulation, which allows for the inclusion of human actors in SDP simulations. Modeling and simulation of Agile SDPs were carried out using this prototype. Experiments show the correspondence of the proposed approach to the needs of dynamically changing and human-factor-dependent SDPs, as well as the possibilities for modeling and simulating the SDP, predicting SDP execution, and observing possible risks.

“…When coupled with descriptive tools, it becomes an effective approach capable of dealing with vast domains of inherent uncertainties [23]. Future study has witnessed a spurt in the use of FCM in a wide range of sciences, including energy [24,25], management [26,27], climate changes [28,29], environmental and ecosystem [30][31][32][33][34][35], regional planning [36], medical and medicine [37][38][39], engineering [40][41][42], and social studies [43,44]. This study applies FCM empowered with realworld narratives to scrutinize the characteristics, interactions, and influence of factors on Iran's SPV sector, and elicit plausible scenarios based on the dynamic behaviors of these influential factors and uncertainties surrounding the sector.…”

Widespread use of promising solar energy is an integral attribute of governments toward global efforts in mitigating future emission and reducing the fossil fuel consumption trajectory. However, the outlook of solar energy development at the strategic level is driven by inherent uncertainties in a long-term perspective. As these unpredictable volatilities come into play, they heavily influence the future trends formed by a range of exogenous and endogenous factors including Political, Economic, Social, Technological, Environmental, and Legal (PESTEL). This study aimed at identifying, characterizing, and analyzing influential PESTEL factors shaping the dynamics of Solar Photovoltaics (SPV) in an uncertain environment. For this purpose, the Fuzzy Cognitive Mapping (FCM) method was employed for the case of Iran to investigate how involved factors dynamically interact and collectively behave in the system. A participatory stepwise framework was developed consisting of three steps by conducting a survey and two workshops with the participation of multidisciplinary stakeholders. Aa a result, a semi-quantitative model was formed in an integrated FCM comprising 31interwoven concepts. To further outline possible future trends, five key concepts were determined that explored four plausible projections of Iran's SPV sector. The scenario outcome suggests that the industry is profoundly affected by external economic and political factors. Two scenarios "Cornered in a Dead-End" and "At Wits' End" project that, by 2030, the sector experiences a declining growth trend. "The Period of Tolerance" scenario does not envisage a dramatic change from the current trajectory, while in only "Blue Sky" the country's SPV sector anticipate a moderate growth.
