【摘要】：物料需求計(jì)劃(MRP)是基于最終產(chǎn)成品結(jié)構(gòu)層次中的項(xiàng)目數(shù)量和級(jí)別,具體針對(duì)每個(gè)物料作為計(jì)劃制定過程中的有效目標(biāo),同時(shí),以完成所有產(chǎn)品的時(shí)間作為標(biāo)準(zhǔn)來對(duì)整個(gè)車間生產(chǎn)計(jì)劃進(jìn)行編制,根據(jù)產(chǎn)品制造周期的長(zhǎng)度來編排每個(gè)物料計(jì)劃時(shí)間的前后順序,以到達(dá)對(duì)企業(yè)生產(chǎn)計(jì)劃安排控制、降低庫(kù)存、降低生產(chǎn)成本、提高準(zhǔn)時(shí)發(fā)貨率的目的。JL管件公司自2014年12月采用SAP下MRP模塊管理生產(chǎn)計(jì)劃以來取得了一定的成績(jī),但通過對(duì)經(jīng)營(yíng)狀況進(jìn)行調(diào)研分析發(fā)現(xiàn),標(biāo)準(zhǔn)功能的物料需求計(jì)劃已經(jīng)不能滿足多品種、小批量生產(chǎn)模式下對(duì)客戶需求的快速響應(yīng)和庫(kù)存減少的需求,同時(shí),國(guó)內(nèi)外的不銹鋼合金鋼行業(yè)競(jìng)爭(zhēng)愈發(fā)激烈,這就導(dǎo)致了JL管件公司在生產(chǎn)計(jì)劃編制和生產(chǎn)管理的時(shí)候出現(xiàn)了很多問題,其中既包含了內(nèi)部管理的問題也有外部環(huán)境的因素,比如對(duì)生產(chǎn)流水線短板工序的控制程度比較低,生產(chǎn)計(jì)劃精確度欠缺,生產(chǎn)現(xiàn)場(chǎng)的實(shí)際情況不能及時(shí)滿足客戶需求,庫(kù)存量比較大,訂單及時(shí)交貨率比較低,客戶頻繁變更訂單導(dǎo)致生產(chǎn)計(jì)劃混亂等。因此,本文從JL管件公司生產(chǎn)計(jì)劃方法、生產(chǎn)計(jì)劃系統(tǒng)以及流程和庫(kù)存管理這幾方面分析和探討,并針對(duì)MRP在JL管件公司的多品種小批量生產(chǎn)計(jì)劃中的問題和缺陷提出了相對(duì)應(yīng)的解決方案。本文以JL管件公司作為案例的研究對(duì)象,根據(jù)公司在MRP在實(shí)際生產(chǎn)計(jì)劃運(yùn)行中存在的問題,針對(duì)性的提出一系列的解決方案。并且通過對(duì)比實(shí)施前后的一些管理指標(biāo),得出了改良方案實(shí)施有效的結(jié)論。研究結(jié)果表明,不同的生產(chǎn)管理理論有不同的優(yōu)勢(shì),在具體是實(shí)施過程中,企業(yè)應(yīng)當(dāng)從其自身的實(shí)際情況出發(fā),結(jié)合其配套的設(shè)施和流程,以滿足自身管理的需求,并且同時(shí)也提高了企業(yè)的競(jìng)爭(zhēng)優(yōu)勢(shì)。本文提出的一些改進(jìn)方法對(duì)國(guó)內(nèi)其它制造企業(yè)針對(duì)多品種小批量生產(chǎn)計(jì)劃的管理也有著極大的借鑒價(jià)值。
[Abstract]:Material requirements Planning (MRP) is based on the number and level of items in the final product structure level, specifically targeting each material as an effective goal in the planning process, and at the same time, To complete all products as the standard for the preparation of the entire workshop production plan, according to the length of the product manufacturing cycle to schedule each material planning time before and after the order, in order to achieve the enterprise production planning control, reduce inventory, The purpose of reducing production cost and improving punctual delivery rate. JL Pipe fittings Company has made some achievements since it adopted MRP module to manage production planning under SAP in December 2014. The material requirement plan of standard function can not meet the demand of many varieties, small batch production mode, the fast response to customer demand and the demand of inventory reduction. At the same time, the competition of stainless steel alloy steel industry at home and abroad is becoming more and more fierce. This led to a lot of problems in production planning and production management in JL Pipe fittings Company, which included both internal management problems and external environmental factors, such as low level of control over production line short plate processes. The accuracy of production planning is not enough, the actual situation of production site can not meet the needs of customers in time, the inventory is relatively large, the timely delivery rate of orders is relatively low, and the frequent changes of orders lead to confusion of production plans and so on. Therefore, this paper analyzes and discusses the production planning method, production planning system, process and inventory management of JL Pipe fittings Company. The corresponding solutions to the problems and defects of MRP in the multi-variety and small-batch production plan of JL Pipe fittings Company are put forward. In this paper, JL Pipe fittings Company as the case study, according to the company in the actual production plan in the operation of the problems, targeted to put forward a series of solutions. By comparing some management indexes before and after implementation, the effective conclusion of the improved scheme is obtained. The research results show that different production management theories have different advantages. In the process of implementation, enterprises should proceed from their own actual conditions and combine their supporting facilities and processes to meet their management needs. At the same time, it also improves the competitive advantage of enterprises. Some improved methods proposed in this paper also have great reference value for the management of multi-variety and small-batch production planning in other domestic manufacturing enterprises.
