The purpose of this study was to design a causal-structural model of entrepreneurship education with an emphasis on the views of the scientific-academic elite. In order to identify the initial dimensions and indicators and to generate the initial model, models and theories on the effective factors in creating entrepreneurship were examined followed by exploratory interviews with experts in the field. Then a Delphi panel consisting of 20 experts was formed. Questionnaires were distributed among the participants, and their opinions were analyzed. The results showed that entrepreneurship education for micro and intermediate educational activities consists of the dimensions of: IT skills, technical skills, entrepreneurial skills, and management skills. These dimensions consist of 47 indicators. The reliability of the questionnaire was assessed using PSSS software and a Cronbach's alpha of 0.89 was obtained. To determine the priority of the dimensions and constituent indices, the pairwise comparison technique was used in X-Press Choice software. The results showed that entrepreneurial skills play the most important role in creating small and medium educational jobs. To determine the effectiveness of the model, a sample of 384 graduates was selected and the final questionnaire was distributed among them. Then the difference in scores before and after the training was considered as a dependent variable. Using SPSS software and multiple regression analysis, the positive relationship between entrepreneurship education and the above skills was confirmed. The results of modeling using Amos software also showed a significant positive relationship between these skills and entrepreneurship training.

Permit to work system  is a formal, documented and written system that aim to control risk of occupations that are considered potentially dangerous. The porpuse of this study was to identify and prioritize the criteria affecting the performance of the permit to work systeam  in an oil refinery.

The present study was designed and implemented in three steps. In the first step, by reviewing previous studies and conducting interviews with experts, the perimarly criteria were identified. In the second step, fuzzy delphi methode was used for determine the final criteria , in this step  opinions of 25 experts on the perimarly criteria were collected and combained . Finally,  fuzzy hierarchical analysis method was used in order to weight and prioritize the identified criteria.

result of Fuzzy Delphi  methode was showed that six criteria,  risk identification and risk assessment, training and competence of individuals, preventive actions , communication, responsibility and coordination as criteria affecting the performance of the permit to work systeam . Prioritization of criteria using fuzzy hierarchical analysis showed that the criterion of responsibility )final weight 0.191( and coordination and communication criteria )final weight 0.134( have the highest and lowest importance among the identification criteria.

In this study, a model of decision making based on Delphi methods and fuzzy hierarchical analysis was introduced to identify the factors affecting the performance of the  permit to work system in an oil refinery.
