The reduction of bullwhip effect by Integrating Information Sharing, Forecasting, Economic Order Quantity (EOQ) - Vendor Management Inventory (VMI) - and Consignment (Cs) Approach

This research aims to create a conceptual method, in order to reduce the effect of bullwhip by integrating information sharing, Forecasting, Economic Order Quantity (EOQ), Vendor Management Inventory (VMI), and Consignment (Cs) methods. The results are used to build an application that can be used for information sharing, simulation using forecasting, and Economic Order Quantity-Vendor Management Inventory-Consignment methods, which can reduce the effect of bullwhip. It can be concluded that through information sharing, the results obtained in the forecasting method is more accurate, because customer requests can be identified by suppliers and retailers. Also, the optimal product lot size and total cost was obtained by using the Economic Order Quantity-Vendor Management Inventory-Consignment model. These aforementioned integration steps were taken as an effort to reduce the effect of bullwhip.
