Abstract Projects are planned based on estimated amounts that are the result of having little information about the future plans. According to the uncertainty of planning, time delays and costs of uncertainty are inevitable. The main objective of this study is to present a new approach based on failure mode and effects analysis and fuzzy logic to identify the affecting risks on duration of projects and ranking them using Kepland technique. In addition, in this research Shannon entropy is used for calculation of the weights of indexes. So after the study of related researches as well as through interviews and Delphi technique, some risks were identified. Then, based on three indicators of risk in the FMEA (severity, probability of occurrence, probability of detection), three questionnaire was prepared and their validity was confirmed by experts and reliability was calculated by Cronbach coefficient using SPSS software. The population of the study is 22 managers and experts that work on Debal Khazaei Company. Using triangular fuzzy numbers, the verbal variables of questionnaires became fuzzy numbers. Shannon entropy is used for calculation of weight of each index. Then, using decision making methods, ELECTRE TAXONOMY, TOPSIS and SAW, the risks are ranked. Finally, because of the relative difference of ranking in different techniques, Kapland technique is used to combine the results. TO help for developing the strategies of responding to the risks, some suggestions are presented. The contribution of this research is the simultaneous use of FMEA and Shannon's entropy to analisys the importance of risks and the ranking of them using Kepland technique. Manuscript profile

Performance evaluation is a fundamental necessity in facing and coping with changes and continuous improvement activities. Insurance companies to determine your current position and survive and thrive in today's competitive world must continually methods and models to assess and improve their performance and activities of the organization are ongoing. The aim of this study is to evaluate the performance of insurance companies based on Shannon's weighting entropy and the ranking method is done according to grey VIKOR technique address. The performance evaluation is conducted based on the Balanced Score card method. Moreover, instead of using the linguistic variables and absolute numbers we will use grey numbers Tuesday parameterization. Grey VIKOR is a one of the most developed approaches of multi-criteria decision making under uncertainty conditions. Furthermore, the actual weights based on the concept of objective to regulate the mental weights of Shannon entropy can be used by the decision-makers. The current study has been worked on five insurance companies. According to the data gathered from the questioners the quantity value of the insurance companies has been calculated based on the final weights resulted from Shannon's weighting entropy and the grey VIKOR method. The results revealed that MELLAT insurance company obtained the highest value of (0.9334) and the lowest value (0) belongs to Dana insurance company. Accordingly, Dana Insurance is ranked in the first position, Iran Insurance the second, Alborz Insurance the third, Asia Insurance the fourth and MELLAT insurance the fifth. Manuscript profile
