Supply Chain Structure

This paper analyzes the intrinsic relationship between the supply chain structure and its key factor, and builds a system dynamics model of supply chain under the advance payment financing business. Establishing the dynamic equations and simulating with Vensim simulation software, the result has been proved that prepayments financing has a positive impact on the supply chain performance.

Practical Implications

Studies show that supply chain structure is a key factor affecting information sharing. Business-to-business (B2B) e-hubs have fundamentally changed many companies’ supply chain structure, from a one-to-many to a many-to-many configuration. Traditional supply chains typically center around one company, which interacts with multiple suppliers or customers, forming a one-to-many structure. B2B e-hubs, on the contrary, usually connect many buyers and sellers together, without being dominated by a single company, thus forming a many-to-many configuration. Information sharing in traditional supply chains has been studied extensively, but little attention has been paid to the same in B2B e-hubs. In this study, the authors identified and examined five information sharing strategies in B2B e-hubs. Agent performances under different information sharing strategies were measured and analyzed using an agent-based e-hub model and practical implications were discussed.

The Iranian chicken industry has always been encountered to high and fluctuated chicken prices. The purpose of this article is to find the best choice to prevent chicken prices from increasing more by investments. System dynamics methodology has been used to modeling, evaluating and optimizing chicken supply chain. Considering the existing capabilities for improvement in supply chain and experts opinion, these strategies were proposed; “reduction of breeding period,” “modernization of production facilities,” “Increase in pellet feed production” and “energy conservation.” After implementing the model and testing various scenarios, strategies were prioritized based on key indicators. At last modernization of production facilities is introduced as the best strategy for the next three years.

With the technological developments and rapid changes in demand pattern, diverse varieties of electronic products are entering into the market with reduced lifecycle which leads to the environmental problems. The awareness of electronic products take-back and recovery has been increasing in electronic products supply chains. In this paper, we build a system dynamics model for electronic products closed-loop supply chain distribution network with the old-for-new policy and three electronic products recovery ways, namely, electronic products remanufacturing, electronic component reuse and remanufacturing, and electronic raw material recovery. In the simulation study, we investigate the significance of various factors including the old-for-new policy, collection and remanufacturing, their interactions and the type of their impact on bullwhip, and profitability through sensitivity analysis. Our results instruct that the old-for-new policy and three electronic products recovery ways can reduce the bullwhip effect in the retailers and the distributors and increases the profitability in the closed-loop supply chain distribution network.
