Abstract In today's competitive marketplace, to increase customer satisfaction and profitability, supply chain management has become more prominent. Therefore, thorough planning and designing the supply chain by seeing all levels and units are essential to growing the efficiency of the entire supply chain. In the present study, an eight-echelon network is designed for a closed-loop agricultural supply chain. These eight echelons are consist of suppliers, farms, distribution centers (DCs), customers, recycling depots, biogas centers, compost production centers, and biogas applicants. To design the agricultural logistics network, a bi-level programming mathematical model is presented that optimizes the network costs and profits. Also, some meta-heuristics and hybrid meta-heuristics are applied for solving the formulated problem. It should be noted that bi-level programming problems are part of the NP-hard class and due to the computational complexity of the problems, the meta-heuristic algorithms are utilized. Finally, various comparisons and analyses are performed to evaluate the model's performance and the capabilities of the solution methods.

Closed Loop Supply Chain

Hazardous materials (hazmat) storage and transportation pose threats to people’s safety and the environment, which creates a need for governments and local authorities to regulate such shipments. This paper proposes a novel mathematical model for what is termed the hazmat closed-loop supply chain network design problem. The model, which can be viewed as a way to combine several directions previously considered in the literature, includes two echelons in the forward direction (production and distribution centers), three echelons in the backward direction (collection, recovery, and disposal centers), and emergency response team positioning. The two objectives of minimizing the strategic, tactical, and operational costs as well as the risk exposure on road networks are considered in this model. Since the forward flow of hazmat is directly related to the reverse flow, and since hazmat accidents can occur at all stages of the lifecycle (storage, shipment, loading, and unloading, etc.), it is argued that such a unified framework is essential. A robust framework is also presented to hedge the optimization model in case of demand and return uncertainty. The performance of both models is evaluated based on a standard dataset from Albany, NY. Considering the trade-offs between cost and risk, the results demonstrate the design of efficient hazmat closed-loop supply chain networks where the risk exposure can be reduced significantly by employing the proposed models.

Carbon Emission Trading

Considering the increasing number of end-of-life goods in the context of improving the ambience and health of a population and their destructive impacts, recycling strategies are important for industries and organizations. In this article, a closed-loop supply chain management containing a single manufacturer, a single retailer, and a third party is introduced in which the manufacturer first propagates newly finished goods and then dispatches some of the finished goods to the retailer considering a single-setup multi-delivery policy. Due to shipping, carbon emission is taken into account as well as a carbon emission trading mechanism to curb the amount of carbon emissions by the retailer. For recycling through collection, inspection, remanufacturing, and landfill, the third party collects the end-of-life goods from its customers and ships perfect products to the manufacturer after a two-stage inspection. In this model, major sources of emissions such as shipping, replenishment orders, and inventory have been taken care of. The minimizing of the total cost relating to the container capacity, shipment numbers, and replenishment cycle length is the main objective of the closed-loop supply chain management for making the system more profitable. Expository numerical explorations, analysis, and graphic representations are conferred to elucidate this model, and it is observed that this model saves some percentage of the cost compared to the existing literature.

Logistics Activity

The article considers the strategic guidelines of the logistics activities of poultry enterprises. It is noted that the strategies of minimizing logistics costs and investing in the logistics network, maximizing and improving logistics services, maximizing income and profits, increasing the competitive advantages of the enterprise, logistics outsourcing are the most widely used logistics strategies. It is proved that the purpose of creating a logistics system is to harmonize the interests of producers, suppliers and consumers. It is established that an important factor in improving the strategic activities of the enterprise is the introduction of the principles of distribution logistics. This concept involves the use of a systematic approach and integrated planning, as well as management of the entire flow of feed, materials, breeding and commercial poultry products in various areas from suppliers, through manufacturers of breeding and breeding products, distribution centers, to the final individual and corporate consumers of poultry products. The main stages of the business process of integration of a poultry enterprise in the supply chain are schematically shown. The necessity of introduction of new, more progressive forms of service in the process of goods movement can be achieved. The need to use regional distribution centers of poultry enterprises in the supply chain, which will significantly reduce the cost of delivery of their products through the formation of optimal transport batches of products from different manufacturers, its packaging and labeling.

This research paper is to use a method of Evolutionary Game to investigate the relationship between a large supplier and a franchised supermarket in China. The authors would like to go through their empirical study with their filtered answers from the survey using SPSS software on agricultural supply chain for their quality safety factors. Their research is using factor analysis with five target factors which are: the excess return, cost, the relative size of cooperative enterprises, hitchhiking, and overflows income. Applying these factors to the evolutionary game model, analyze the earning status from the both players under their own policies, then make suggestions or proposals for quality and safety issues of agricultural supply chain management.
