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.

The increased knowledge about environment and decline in reservoirs of fossil resources has led the industry to enhance and produce other sustainable fuels by using renewable, which are environmentally acceptable. Biofuel is a kind of fuel derived from biomass resources. Biomass is also the source of fossil fuels that are used today; however, this biomass has been formed over long years. The reduction in fossil fuel resources and the destructive effect of these fuels on the environment have made researchers replace such resources. Therefore, the extant study presented a multi-objective mathematical model for a biofuel sustainable supply chain, by consideration of demand uncertainty. Finally, the research developed the mathematical model considering uncertainty and using Bertsimas and Sim Robustness Approach. According to the proposed model, sustainability objectives were discussed and investigated, including economic, social, and environmental issues. Ultimately, the presented model was confirmed by using the epsilon constrained method (ε constrained method) and the model was validated using the integrated ε constrained-Benders Approach.

The use of bamboo is growing as raw material for various industrial purposes so categorized as the main support of the village community economy. This study aims to analyze: 1) mechanism of bamboo supply chain of bamboo, 2) value added of bamboo supply chain actors, 3) factors that influence the income of stick business. The population were bamboo farmers and stick entrepreneurs in Dalisodo Village respectively 83 and 78 person. Samples were determined using simple random sampling method of 36 bamboo farmers and 35 stick entrepreneurs. Data collected were analyzed descriptively quantitatively for bamboo farm and stick business income, and multiple linear regression to analyze the determinants of stick business income. The results show that the bamboo business income is IDR 343,450 per 900 kg of wet bamboo while the added value obtained by stick businessmen is IDR 962,400 per 300 kg. Age, business experience, raw materials and labor had a significant effect on stick business income.

Twenty first century is described by knowledge development and its effect on all organizational dimensions. Today, knowledge is considered as the key and sometimes the only source of competitive advantage for organizations; that is why managers and organizations focus on utilizing some methods for knowledge acquisition, storage, and knowledge application in the present dynamic and competitive environment to provide access and quick transfer of knowledge in system using knowledge management. Therefore, the present research intends to present a model for identifying the effect of knowledge level on supply chain performance using modeling structural equations. Research statistical population included all automotive industries in Iran such as component makers, sale representatives, manufacturing units, etc. 350 were randomly selected as research sample and a questionnaire was distributed, 240 of which were returned. Finally, the positive, significant effect of business attitudes, organizational memory and individuals’ knowledge on supply chain performance in Iran automotive industry was maintained; whereas, the positive, significant effect of customer knowledge, beneficiaries’ relationships, knowledge in processes, and knowledge in manufacturing and services was rejected.

Knowledge management is considered as one of the most significant competitive resources for any organization such that most believe that the faster the companies acquire knowledge taking into application, the more they are successful in a competitive market. On the other hand, the competition among companies is no more important; instead, the competition among supply chains is highly focused in order to provide the most value to the customer. Research statistical population included 30 individuals of all practitioners and middle management experts in National copper industries company headquarter. The present research used Fuzzy Analytic Hierarchy Process (FAHP) to rank knowledge management effective factors in supply chain of national Iranian copper industries company. Research results showed that management factors, knowledge creation, acquisition and production process, knowledge assessment and feedback process, knowledge transformation, sharing and distribution process, organizational culture, knowledge use, application and utilization process as well as employees’ characteristics are in order the most to the least important knowledge management criteria in supply chain of national copper industries company through using FAHP technique.
