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...
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,...
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...
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...
