The viewpoint that logistic is the third origin of profit has been generally recognized, and supply chain inventory management has been the focus of management research accordingly. The enterprises of our country are obsessed by the problem of inventory all along. Based on former researches, the writer applies System Dynamics to producer inventory management. After establishing SD inventory models...
This paper studies a vendor-managed-inventory (VMI) supply chain where a manufacturer, as a vendor, procures a type of nondeteriorating raw material to produce a deteriorating product, and distribute it to multiple retailers. The price of the product offered by one retailer is also influenced by the prices offered by other retailers because consumers can choose the product from any of the retailers...
Two typical application lays of VMI mode are introduced, and the VMI mode of upstream lay is addressed to research on. In case of the indefinite demand, economic effects of every node in both traditional mode and VMI mode are compared by setting up mathematic models and using simulation skills. Basing on the above analyses, the paper tries to find a rational space of supplier's sales price which can...
In this study, we (attempted to) demonstrate the benefit of information sharing on supply chain performance in a three echelon supply chain that consists of one distribution center and two store retailers. To perform the analysis, the discrete event simulation model for inventory replenishment process was developed based on the actual data obtained from the retailer. Various replenishment information...
Firstly, this paper combines the principles of inventory management under VMI and characteristics of the system dynamics in decision making the research on the supplier strategy under VMI suitability and superiority. Secondly, according to the demand of real system and the requirements of system dynamics models, we delimit the boundary of this model. Furthermore, based on the clear system boundary,...
This paper describes the application of System Dynamic in supply chain management's area. Analyzing the systematization and dynamics' character on Supply Chain, it shows feasibility of applying System Dynamic and research method of Supply Chain System based on System Dynamic. Through analyzing SD model it showed that human resources and fixed costs perturbed lowly for performance, but fluctuation...
Flexibility is one of important indicators for measuring the characteristics of supply chain; the author introduces and evaluates four ways of measuring the flexibility of supply chain by reviewing the research results of measurement model of flexibility of supply chain. Basing on this way, it builds a measurement model of flexibility of supply chain which faces to customer directly, and shows the...
In this paper, we present a simulation model for the multi-echelon inventory optimization problems using Arena. In the multi-echelon inventory there are five members: a manufacturer, a distribution center and three retailers. Our analysis concentrates on the relationship between the fill-rates of retailers and the average inventory level of the entire supply chain. We assume that customer's demand...
With the development of the information and internet technology, Vendor-Managed-Inventory (VMI) has been adopted by more and more companies. In this paper, a two-echelon supply chain inventory decision model is discussed. The products are perishable and sold over a single selling season. First a VMI model is constructed, and the supply chain members' optimal decisions are gained. Under VMI, the supplier...
Inventory misplacement and inaccuracies contribute significantly to the operational expense of the overall supply chain. Radio Frequency Identification (RFID) technology has gained prominence as a solution to this approach. However, issues such as presence of metals and frequency interference hamper its performance and value derived out of its implementation in many environments. To analyze the true...
The paper examines the impact of the role of 3PL on the performance of a two-level supply chain with a supplier and a budget-constrained retailer. We define two alternative roles of 3PL in a budget-constrained supply chain: Convention and Delegation. In convention model, the 3PL offers a traditional role of logistics providers, while in delegation model the 3PL presents the role of both logistics...
Vendor-managed inventory (VMI) model is a new inventory management mode in supply chain, under which the supplier takes charge of inventory management, and bears all inventory risk. A two-echelon supply chain, operating under a VMI mode, is put forward. And the products are perishable and sold over a single selling season. And a simple VMI model is first discussed, and the supplierpsilas optimal inventory...
