Analysis of a Vendor Managed Consignment Inventory System with Kan-ban Withdrawals and Payment Delays

Abstract

Vendor Managed Inventory (VMI) System with Consignment Inventory (CI) policy is a solution for many supply chain leaders in a highly competitive market. In this paper, totally eight different inventory supply chain models are studied. The profit function of supplier and manufacturer in different environments are compared in order to show the profitability of the overall supply chain management system in a manufacturing industry with different time horizons. The inventory systems are applied on a supply chain consisting of a single supplier and a manufacturer. The main focus of this study is to analyze the effect of payment deferral and the time value of money in push and pull (Kanban) manufacturing systems when VMI-CI policy is applied.
