Emanfactoning & optimized planning

Abstract

Abstract This thesis deals with one ofthe most importing manufacturing model which is material requirements planning. It is a form of backward scheduling. MRP is an information management system that ensures that material is not ordered for production until there exists an end item for it to produce: MRP starts with the finished product and works backward to plan the requirements ofall necessary raw materials using BOM issue. The major idea of MRP is to keep stock value to minimum. MRP is applicable to discrete and dependent demand systems, allocating items in inventory when they are required. The system must be time phased so that predetermined materials arrive at the point in time when they are needed. Time phasing results in reduced inventory levels, since holding costs are a factor in detennining ordered raw material or work-in-progress (WlP). Thesis aims to realize an integrated system that has rapid response to changing requirements and capability to integrate heterogeneous manufacturing activities. At first, the application accepts the customer’s order (through Sales Eng.) and performs material requirement planning process, which results is material scheduling and deliveries date. Then MRP monitor daily planned order to production model that carries out real-time scheduling and production. At the same time, MRP sends order to supplier for purchasing raw materials (shortage). After completing production task, production model returns the relevant infomiation about finished parts. Once the customers add or modify orders, MRP system will update data automatically to respond to the changes ofcustomer requirements rapidly. The smart draw tools are applied for analyzing and designing phase while total I application in which MRP system uses visual F0xPro version 6 as an implementation language. Kevwordsz MRP.
