The purpose of this study is to evaluate the drivers of bullwhip effect in supply chain of the pharmaceutical industry. This research is descriptive in terms of method and applied in terms of purpose. Conducting the research, first, based on the reviewing the literature on bullwhip effect in the supply chain, affecting drivers were extracted and were sent to 15 experts in form of a questionnaire. Then, using the fuzzy Delphi method, the final affecting criteria on bullwhip effect in the supply chain of the pharmaceutical industry were identified. Finally, in order to examine the relationships between the 13 basic drivers, another questionnaire was designed and asked the experts to fill it, where based on their answers and using DEMATEL and fuzzy cognitive map methods, critical drivers were determined. FCMapper software was used to conduct fuzzy cognitive map method and MATLAB was used for the DEMATEL method. In terms of centrality index in fuzzy cognitive map method, structured inventory control process, delivery time, inventory storage of chain elements, inventory policy and product return rate are 5 criteria of critical importance. In addition, the indicators of the number of echelons, forecasting (method) error and up-to-date demand forecast are in the eleventh to thirteenth ranks. Based on the results of DEMATEL method, inventory policy, price fluctuations, inventory storage of chain elements, structured inventory control process, differences with the desired inventory and information transparency were identified as the main drivers of bullwhip effect in the supply chain of the pharmaceutical industry.

The field of humanities is different from other fields in many aspects, therefore, in order to develop academic entrepreneurship in this field, we need its special model. In this article, two goals are pursued, first, the key components of the development of academic entrepreneurship are identified, and then we discuss the prioritization and influence of the dimensions on each other. This article is practical in terms of its purpose. After carrying out library studies, using the fuzzy Delphi method, we have identified the dimensions, and in the second step, we have used the Dematel method and the ranking of the components using the analytical network process (ANP) to find cause and effect relationships. Therefore, the components of the government's role, entrepreneurial culture, the educational structure and financial infrastructure of the penetrating (cause) and the components of the university structure, research and commercialization and the communication links under the influence (effect) are introduced. The first priority of university entrepreneurship development was entrepreneurial culture and in order expanded developmental periphery including research and commercialization, communication links, strengthened steering core including university structure, stimulated academic heartland includes educational structure, financial resources including financial infrastructure and the least important is the government component.

Background: Official websites of tourism destinations provide an important digital content and are considered as widely-used tools of introducing destinations and presenting tourism products to the potential tourists. Improving the usability of websites helps the tourism destinations in achieving their goals. Websites usability is measured based on different criteria. Purpose: This paper evaluates and compares the usability of Iran and Malaysia official tourism destination websites –which are regarded as quite comparable in their tourism products and market- using seven criteria of content, visual attractiveness, infrastructure, interaction and responsiveness, navigation, customization, and product provision. Method: In order to do this evaluation, pairwise comparison questionnaires of the criteria were developed based on DEMATEL and ANP techniques and were answered online by 10 tourism experts in Iran. Websites’ usability analysis was performed using a combination of two MCDM (Multiple Criteria Decision Making) techniques that are DEMATEL and ANP so that the causal relations of the criteria are identified along with the ranking of their significance. Findings: The findings of the research show “infrastructure” as the dispatcher criterion, “product provision” as the receiver, and “content” as the most important criterion in the usability of tourism destinations’ websites. The findings also revealed the superiority of Malaysia’s official tourism website as compared to that of Iran.
