Competitiveness is one of the factors successful organizations excel in, and they will do anything necessary to gain an edge over their competitors. The system dynamics approach to simulation modelling is being considered as one of the methods to increase competitiveness. System dynamics is essentially a methodology suited to studying and managing complex feedback systems and provides a means for understanding the causes of industry behaviour. This research builds a complete system dynamics model for internal supply chain events (from order to ship-out) from the perspectives of a semiconductor company. System dynamics models are simulation-based models that allow the investigation and identification of discrepancies between the business policy and the actual practice of key events as well as provide a better visibility of the company’s system. With the understanding of the internal workings of the supply chain system, experiments with the simulation model could provide alternative configurations to achieve better performance. This research utilizes system dynamics to better understand the supply chain system and with it, to find better solutions through experimentations with a few key variables in the supply chain system. The result of this research reveals that the company could achieve 25% reduction in inventory cost should the recommendations be followed.

A study has been conducted to understand the effect of bullwhip phenomenon in a supply chain system. The hypothetical data collected from the study is used to make a model which can be used to simulate the operation of the system with moderate complexity. System dynamics approach is used to create an open loop system. The phenomenon used is slightly modified and empirically analysed to bring down its adverse effect on the system. The results obtained graphically are emphasising the effect of bullwhip on the various levels of the supply chain system.

The Difference

In a supply chain system, the prices with which the suppliers supply its local commodity to the retailers should satisfy the requirements of the retailers and the consumers. The supply and demand scheme satisfying these requirements is reduced into fuzzy relation inequalities (FRIs) with min-product composition. Due to the difference between the min-product composition and the classical max-t-norm one, we first study the resolution of such min-product FRI system. For optimization management in the supply chain system, we further investigate a maximin programming problem subject to the min-product FRIs. An algorithm is proposed to obtain the optimal solution based on the quasi-maximal matrix and corresponding index set. To illustrate the efficiency of our proposed algorithm, we provide a simple numerical example. The obtained optimal solution reflects an optimal pricing scheme, which maximizes the minimum prices of the commodity from the suppliers.

The Impact

The aim of this paper is to understand how disruptions effect on closed-loop supply chain, and how to achieve the coordination of closed-loop supply chain under disruptions situation for the whole supply chain system. Design/methodology/approach- This paper analyzed the effect caused by the disruptions of the closed-loop supply chain from both supply and demand , and applied the established margin profits sharing contract to achieve coordination under the disruptions. Findings- From both supply side and demand side, it drew how the disruptions affect the closed-loop supply chain. When the disruptions have less effect on the forward and reverse cost of closed-loop supply chain, the impact of the closed-loop supply chain is controllable; when the disruptions have lager effect on the forward and reverse cost of closed-loop supply chain, the impact of the closed-loop supply chain is uncontrollable. Research limitations/implications- In this paper, the contract costs are ignored for zero. While in actual situation, to maintain the efficient implementation of this contract must spend considerable cost. Sometimes the cost may be too high to become hinder between manufacturers and retailers. This paper also does not make in-depth study on this issue, so it will be further study in the future. Originality/value- This paper also designed a set of differential profit sharing contract based on revenue sharing contract mechanism. The contract is easy to be managed, easy to be operated, making the closed-loop supply chain system can achieve coordination whether in steady state or under disruptions.

System dynamics provides a more intuitive and effective tool for system analysis in area supply chain logistics. By using method of system dynamics, this paper builds up a 3PL-HUB three echelon supply chain system from the perspective of costs, compares supply chain logistics costs variation in two cases with and without 3PL-HUB involved in, simulates logistics costs of each node enterprise, and fully analyzes the influence of 3PL-HUB on bullwhip effect and fluctuation of inventory of supply chain members. It shows that 3PL-HUB can reduce costs and benefit all the enterprises of whole supply chain, which represents a method to enhance supply chain synergy.

Revenue Model

By establishing a two-level symbiotic supply chain system consisting of one supplier and one manufacturer, we use Stackelberg method to analyze the optimal price and revenue model of supplier and manufacturer in the symbiotic supply chain under two power structures in which the supplier and manufacturer are dominant respectively, and analyze the influence of the degree of symbiosis and power structure on the model. Through comparative analysis, we find that: There is a relationship between the income level and the degree of symbiosis in the symbiotic supply chain. The change of power structure will affect the relative benefits of suppliers and manufacturers in the symbiotic supply chain. The manufacturer’s expected unit product revenue will affect the supply chain revenue when the manufacturer is dominant. Finally, the sensitivity analysis of relevant parameters is carried out through an example analysis, and the validity of the conclusion is verified. This paper has a guiding significance for the behavior of enterprises in the cogeneration supply chain.
