using the mathematic techniques such as fuzzy approach has useful outcomes for production planning in different sources. in this paper lgp1 was used to model the objectives such as: avoidance of shortage or surplus of demand, access to maximum of income, using the normal capacity of production and organizing the inventory of warehouse, within the framework of goal constraints like balancing be...

In this paper, we study a logistics network design problem with vendor managed inventory in which the company is in charge of managing inventory for its downstream warehouses and retailers, and can choose whether to satisfy each retailer’s demand. The problem incorporates the location, transportation, pricing, and warehouse-retailer echelon inventory replenishment decisions. Traditionally, thes...

The Economic Production Quantity (EPQ) is one of the most applicable model in production and inventory control environments. Like other classical production and inventory control models, it is derived based upon assumptions that cause limited real-world applications. Continuous and constant-rate delivery of orders, infinite availability of warehouse spaces, and applicability on a single product...

When the theory of constraints (TOC) supply chain replenishment system (TOC-SCRS) is deployed in a plant or a central warehouse, replenishment frequency (RF) becomes one of the important decision parameters and depends on the sales or replenishment quantity (RQ) in the plant. The higher RF is preferred by TOC for the low inventory and the fast response to different market requirements. However,...

This paper considers a two-echelon distribution system which consists of a single warehouse serving N (possibly non-identical) retailers that face discrete stochastic demand of the customers. The warehouse orders from an exogenous supplier with ample stock. Orders arrive at the warehouse after a fixed leadtime. The warehouse satisfies, if possible, the replenishment requests from the retailers....

NVA waste is a common activity in practically all construction projects and can affect the performance of those as whole. In Cikarang, West Java, this also occurred PT “XYZ” Warehouse Building Project. The goal study was to ascertain how XYZ's warehouse project affected associated with Overproduction, Inventory, Defect, Motion, Transportation, Processing (Over processing), Waiting. study's find...

The inventory routing problem presented in this study is a one-to-many distribution network consisting of a manufacturer that produces multi products to be transported to many geographically dispersed customers. We consider a finite horizon where a fleet of capacitated homogeneous vehicles, housed at a depot/warehouse, transports products from the warehouse to meet the demand specified by the c...

Original scientific paper Warehouse management is one of the most important legs in supply chain operations and production management. To support that warehouse execution, a warehouse management system is required. Many warehouses have used various methods to handle this difficult and time consuming evaluation process. The purpose of this paper is to provide a decision support model to make a c...
