One of the issues considered by the projects responsible especially project managers is the execution of project activities according to time schedule. The very difficult nature of that issue is also another reason for the researchers to take much note of it. Therefore, there are especial techniques and methods to solve those issues. Also, project managers pay much attention to the stability of the time schedule as it is important for them. This paper is provided with a real project time schedule for a refinery by using stable time schedule. Particle swarm optimization algorithm is suggested to resolve the problem since the project time schedule has resources limitation including NP- Hard. In order to accesses the validation of the model, 4 issues with small scales has been selected and the results from the suggested algorithm was compared with the accurate result obtained from lingo software. These results indicate that the suggested algorithm is effective and convergent with the optimized result.

An important factor of survival in today’s competitive environment is to reduce production costs of products. Choosing the right suppliers can significantly reduce procurement costs and increase the competitiveness of the organization. Increasing concerns about environmental warnings have attracted attentions of customers¡ governments and organizations and resulted to take care about environmental requirements for products production. As the majority of products components and its material supply from external suppliers¡ consideration about supply process indicators is important. Greening supply chain process is an opportunity for those people are taking care about sustainable demand and environmental business performances. We employed TOPSIS to weight and rank and DEMATEL to evaluate relationships of indicators. After computing the weight of indicators¡ quality received the highest score as well as environmental performance achieved the lowest score in our evaluation. After ranking indicators¡ it was resulted that environmental management and reverse logistic received the highest and lowest in our assessment. The cause and effect relationship of supplier selection indicators in Fulad Gilan Company shows that the reverse logistic¡ environmental performance as well as cost are the most unaffected rather than other indicators and also the impact of environmental performance¡ cost and supplier collaboration are higher than other indicators.

Present research intends to look into the role of the strategic thinking in implementation of the EFQM model through organizational learning within the logistics department of the Ministry of Energy as well as the Ministry’s subsidiary companies. To do this, four hypotheses formulation are presented and tested. The present research is based on the three variables: the strategic thinking as the independent variable, implementation of the EFQM model as dependent variable and organizational learning as mediator variable. The current research method in terms of applied objective, strategies and data collection is solidarity, quantitative, and survey questionnaire respectively. In this survey, statistical society includes all managers and field staff working for the Ministry of Energy and subsidiary companies in the Iran with the number of 35324 persons, who are serving in 2015. Sampling in this study randomly with stratified kind and using Krejcie and Morgan table was designed for 384 people. Data analysis was conducted by applying the software’s such as SPSS statistical, Excel and Lisrel. The results of the proposed approach showed that strategic thinking and organizational learning both have a positive impact on the establishment of EFQM. Results of the fitting model indicated that the research data are fitting with the research conceptual model, so the model was verified. Based on the results of the hypotheses tests and given the fact that all the three hypotheses of the research were verified it was concluded that the strategic thinking directly and through the organizational learning affected on implementation of the desired organizational model.

Credit transaction is an important strategy to increase profitability in the known inventory management. And how to determine the validity of the order depends on the retailer. If the retailer’s order is less than of the default determined by the supplier, a fraction of the amount is received and the remaining would be paid in installment based on the due time. If the order is more than the default the entire payment would be set based on the determined installment. Research has shown that the models to assume the quality of products have been omitted. The main goal of this study was to introduce a model that simultaneously considers the validity of the transaction and the product is assumed disability. The results of this study are to provide methods to determine the optimal policy solution for ordering and replenishment time from the retailer. In order to optimize the implementation of the economic order of inequality arithmetic-geometric model is used.

This research reports a study of industry-university research collaborations aimed at the development of best practices to enhance the impact of such collaborations on company competitiveness. The data sample involves research-intensive companies which engage in collaborative research on a regular basis. Over 100 different collaborations projects are analyzed through interviews with the responsible project managers and with senior technology officers. The interviewees provided both quantitative and qualitative information about the success and lack of success of the collaborations. Based on these data, seven best practices for managing collaborations have been defined which, when taken together, significantly contribute to the long-term success of the collaboration. These practices are: 1) select collaboration projects that complement company R&D; 2) select university researchers who understand specific industry goals and practices; 3) select project managers with strong boundary spanning capabilities; 4) promote longer collaboration timeframes; 5) provide appropriate internal support for project management; 6) conduct regular meetings at the company between university and industry researchers; 7) build awareness of the university project inside the company.

In the recent years, using information technology in Iran industries, mostly in banking, has been increased. Selecting the best site location for Automated Teller Machines (ATM) is also an important Subject for banking industry. Site locating Sciences have always been searching for new optimization methods to find the best location of their case studies. Using Multi-Criteria Decision-Making methods can be expected that the candidate places satisfy the criteria by their weight ratio. Also the use of fuzzy logic in decision making, has been solved the problem of uncertainty and imprecision in assigning the weight of the criteria. So, the applied research study has been using a combined approach of MCDM in a fuzzy environment to provide a new method in Gharzolhasane Mehr Iran Bank ATMs site locating. Regarding the high costs of locating ATMs, the purpose of this study is to provide a method for selecting the best range of these devices Location to increase efficiency and services. Based on the similar studies, a decision criterion was extracted and weighted with FPM Procedure by using QMB and Banking industry expert’s opinions. Then the Location candidates points were ranked by Fuzzy Graph theory and matrix approach method.

IT organizations have capabilities to create value, so they have made huge investments for the deployment of information technology. One of the values that organizations can create is to use this technology in their organizations in order to empower the employees. The aim of this study is to examine the effects of information technology on the job empowerment. The population consists of staff working at Kermanshah province in the west regional electric distribution company. Using the systematic random sampling method, the sample size is 181 people. The questionnaire’s validity and reliability was measured and approved. In this study, the use of information technology in the organization was studied, so after ensuring its application, its effects on empowering employees were investigated. For this purpose, relevant indicators of empowerment were considered, including improving the quality of performance, knowledge, job opportunities, independence and freedom of action, responsibility, decisionmaking, self-control and identified professional development. The results of this study showed that the use of IT to improve the quality of performance is (.011 ₌ α), Knowledge (.000₌α), Job opportunities (.000₌α), Independence and freedom of action (.000₌ α), Responsible for deciding (.002₌ α), Self-control (.000₌ α) and professional development of employees (.000₌α) and all show that there is a significant positive relationship.
