The producer can warehouse the perishable items and reuse them in the production line by creating an appropriate cooperation relationship and sharing information related to demand and stocks in order to provide the field to save money, reduce the environmental population, and use natural resources less. Therefore, it is also necessary to use the concept of the supply chain of perishable items in the supply chain. In this study a new approach will be provided to develop the agility of the supply chain to establish an integrated and agile supply chain to create an informational and operational linking bridge between different sections of the supply chain. Hence, a multi-objective mathematical model will be presented considering the maximization of the level of agility, the minimization of the perishing of goods, minimization of the time of distributing goods by systemizing the retail distribution system and since the agile supply chain model is considered as difficult problems, Epsilon- Constraint method and Benders Exact Solution method will be used to develop this research. Benders method is a decomposition algorithm that creates smaller sections of agility in solving the model by decomposing the mathematical model. First, the model is evaluated, and a problem is designed to assess the performance of the proposed model, and it is solved by using GAMS and CPLEX solver. Then the validity of the provided model is analyzed by the approach of the meta-heuristic algorithm Moka.

Nowadays, recognizing and applying managerial skills truly target their activities at achieving goals. The aim of this study is to present a model for measuring managerial skills in different organizational levels. Regarding method, this study has a mixed method (using qualitative meta-synthesis method and Delphi method in the first phase and quantitative survey method and its analysis by means of DANP method in the second phase). And, regarding the goal, this is a practical study. In the first phase of the study, all related research published in Iranian and foreign valid scientific databases were studied using meta-synthesis method and the model was confirmed by Delphi. In the second phase, the statistical population was consisted of all managers in South Zagros Oil and Gas Exploitation Company chosen by purposive sampling method. The results of this study shows that the dimensions of team working, technology and problem solving skills have the most importance among top managers respectively; the dimensions of technology, learning and communication skills have the most importance among middle managers respectively, and the dimensions of learning, communication and technology skills have the most importance among first-line managers respectively.
