“…For example, multi-objective mixed integer linear programming is used to improve inventory management efficiency and supply chain resilience [23]. Distributionally robust optimization methods are applied to optimize the dual-channel inventory warehouse structure [24]. The combined inventory method is applied to coordinate direct market demand and replenishment orders from downstream firms [25].…”

Supply chain coordination has been a research hot spot in supply chain management. This paper constructs a secondary supply chain system. Taking the abatement of the bullwhip effect and the double marginal effect as the coordination objective, a simulation study of supply chain decision coordination was conducted using system dynamics. First, by controlling the lead time, it was found that in the decentralized decision-making model, the profit of the supplier and the whole supply chain increases with the shortening of the lead time, and vice versa for the retailer. In the centralized decision-making model with the addition of information sharing and contract, it was found that the retailer’s profit is consistent with the trend of the supplier and the supply chain as a whole, and the supplier’s profit is lower than that of decentralized decision making in the pre-cooperation period. In addition, it is also found that adjusting the contract parameters can effectively improve the situation. Finally, the above models were analyzed for supply chain coordination decisions based on two scenarios: “cooperative stability” or “balance of effects”.

In today’s society, the amount of data available in many area has made it more important than ever to use effective technological tools for accurate and clear analysis and presentation of information. Therefore, the main objective of the research is to implement a Web/mobile system to improve inventory management in a private company. It has been developed under an agile extreme programming XP methodology, taking into account the following phases, which are carried out four structural activities planning, design, coding and testing. In addition, the following technologies were chosen: such as with programming languages PHP, with markup language PHP, MySql v. 10.0 as database system MySql v. 10.0, and cascading style sheets CSS for visual customisation. Therefore, the results showl a 13% improvement in the efficiency of the percentage of spools to be located (PSL, a 28% a better control of the index of percentage of inventoried coils (IC) and an 1,1% difference in efficiency of the Productivity per user (PU) index. With the implementation of a web-based web/mobile inventory management system to improve inventory control and mobile to better control of a company inventory management, using as a reference the most agile methodology to diversify the cases and functionalities contained in the system.

“…Moreover, the demand uncertainty may have a significant impact on the performance of the dual-channel supply chain system of a and the dual-channel supply chain cannot be coordinated any more [3,4]. Thus, it is becoming increasingly important to handle the demand uncertainty in an effective way in order to ensure the success of dual-channel supply chain management [5].…”

Channel Competition and Coordination of a Dual-Channel Supply Chain under Interval Demand

Interval demand is becoming more common than ever before, since the variation bounds of uncertain demand are only required in practice, and they could be obtained through only a small amount of uncertain information. The goal of this paper is to analyze the optimal decision and coordination of a competitive dual-channel supply chain under an interval uncertain demand. For this purpose, we establish a centralized decision model and a wholesale price contract model under both interval demand and channel competition, respectively. Meanwhile, both the satisfaction degree of interval and the order relation of interval number are proposed to convert interval uncertain optimization problems to deterministic ones. Then, we derive the optimal pricing decisions, ordering quantities, and performances of partners and the supply chain system. Meanwhile, a revenue sharing contract is proposed to coordinate the competitive dual-channel supply chain under interval demand. Moreover, we found that the bounds of interval demand and channel sensitivities affect the optimal strategies and revenue sharing contract under interval uncertainty. Finally, we present a numerical analysis to illustrate the proposed results in this paper and conduct sensitivity analyses. The findings of this paper provide important references for decision makers and managers to make scientific decisions in an interval uncertain environment.
