【摘要】：物料需求计划(MRP)是基于最终产成品结构层次中的项目数量和级别,具体针对每个物料作为计划制定过程中的有效目标,同时,以完成所有产品的时间作为标准来对整个车间生产计划进行编制,根据产品制造周期的长度来编排每个物料计划时间的前后顺序,以到达对企业生产计划安排控制、降低库存、降低生产成本、提高准时发货率的目的。JL管件公司自2014年12月采用SAP下MRP模块管理生产计划以来取得了一定的成绩,但通过对经营状况进行调研分析发现,标准功能的物料需求计划已经不能满足多品种、小批量生产模式下对客户需求的快速响应和库存减少的需求,同时,国内外的不锈钢合金钢行业竞争愈发激烈,这就导致了JL管件公司在生产计划编制和生产管理的时候出现了很多问题,其中既包含了内部管理的问题也有外部环境的因素,比如对生产流水线短板工序的控制程度比较低,生产计划精确度欠缺,生产现场的实际情况不能及时满足客户需求,库存量比较大,订单及时交货率比较低,客户频繁变更订单导致生产计划混乱等。因此,本文从JL管件公司生产计划方法、生产计划系统以及流程和库存管理这几方面分析和探讨,并针对MRP在JL管件公司的多品种小批量生产计划中的问题和缺陷提出了相对应的解决方案。本文以JL管件公司作为案例的研究对象,根据公司在MRP在实际生产计划运行中存在的问题,针对性的提出一系列的解决方案。并且通过对比实施前后的一些管理指标,得出了改良方案实施有效的结论。研究结果表明,不同的生产管理理论有不同的优势,在具体是实施过程中,企业应当从其自身的实际情况出发,结合其配套的设施和流程,以满足自身管理的需求,并且同时也提高了企业的竞争优势。本文提出的一些改进方法对国内其它制造企业针对多品种小批量生产计划的管理也有着极大的借鉴价值。
[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.
