基于asprova的某企業(yè)的生產(chǎn)計劃與排程工作的優(yōu)化

摘 要
　　　在制造型企業(yè)中，根據(jù)己有的資源，包括工具、設(shè)備、工人等的具體情況，以及各種約束條件，對現(xiàn)有訂單需要生產(chǎn)的產(chǎn)品制定生產(chǎn)計劃是一項非常重要的工作。生產(chǎn)計劃的質(zhì)量直接影響到能否給客戶一個合理的可以接受的交貨期，并且做到最低的庫存，最短的制造提前期。訂單的完成情況會直接影響到企業(yè)的客戶滿意度，進而影響企業(yè)的長遠(yuǎn)發(fā)展。
　　　由于ERP生產(chǎn)計劃不準(zhǔn)確，它的生產(chǎn)計劃與排程模塊很難滿足企業(yè)的需要。而APS系統(tǒng)是在ERP的基礎(chǔ)上不斷發(fā)展起來的，它彌補了ERP的多種不足之處，使生產(chǎn)從計劃到車間執(zhí)行、生產(chǎn)調(diào)度一氣呵成，它以獨有的優(yōu)勢很好地解決了企業(yè)在生產(chǎn)計劃與排程上的難題。
　　　本論文首先對APS（高級計劃排程）基礎(chǔ)理論進行研究，介紹了高級計劃排程的概念和基本原理，并做以詳細(xì)分析說明。然后對某一現(xiàn)實食品制造企業(yè)的現(xiàn)狀與存在的問題進行論述，運用asprova軟件對生產(chǎn)計劃與排程工作進行建模與設(shè)計。asprova的模擬結(jié)果展示了APS在生產(chǎn)計劃與排程上的優(yōu)勢。

Based On The Asprova Of A Certain Enterprise's Production Planning And Scheduling Optimization Of Work
ABSTRACT
　　　In manufacturing enterprises, according to some of their own resources, including tools, equipment, works and so on the specific circumstances, as well as variety of constraints, it is a very important job to develop the production planning & schedule of products on the existing orders .The production planning & schedule has a direct impact on giving customers a reasonable & acceptable delivery, and to achieve the lowest inventories, to create the shortest lead time. the completion of orders will have a direct impact on the customer satisfaction, thereby affecting the long-term development.
　　　For the production planning of ERP is not accurate, it is hard to meet the need of the enterprise in the production planning & scheduling. However, APS system is continually on the basis of ERP, it makes up a variety deficiencies of ERP. integration of the workshop task and the workshop work function, making the production plan to shop execution, production scheduling in one take, with the unique advantages it easily solutes the problem of enterprise in the production planning and scheduling.
　　　This article first introduces the basic theory of the APS and the differences and relations among APS, MRP and ERP. And then discusses the problems of a real food manufacturing enterprise, by using the asprova software combined with the actual situation of an enterprise to model and design production planning and scheduling. The simulation results of asprova shows the absolute advantage of the APS in production planning and scheduling.
KEY WORDS: ERP,APS, asprova, design
