【摘要】：为适应日益激烈的竞争环境,企业逐渐采用以短交期、多品种、小批量混流生产为特征的精益生产方式。精益物流能够适应精益生产并有效管理企业的物料流、信息流和劳动力,达到在正确时间,将合格产品,按需求数量,送达指定位置的目标,追求消灭包括库存在内的一切浪费,因此对生产物流系统进行精益研究是有实际意义的。论文从L公司生产运营现状出发,对其以生产计划模型建设为主线的精益物流六个模块搭建做了重点分析,提出当前该公司物流管理存在的两大问题：一是物料订购策略不合理带来的库存过高问题；二是配送模式和配送路径缺少系统的规划带来的配送混乱和效率低下问题,并由此按照精益物流理念对该公司生产物流库存控制和配送做了重点研究： (1)构建精益生产计划模型,在物料需求计划确定的前提下,对物料按照价值和品种进行ABC分类,设定零缺货前提,按照库存成本最低原则建立模型,分别对A类、B类、C类物料进行设计计算和对比分析,确定了各类物料的订货策略,达到以最低的库存占用、最少的管理成本满足连续流生产的目标。 (2)对物料按照形状特征进行分类,在满足连续流生产的前提下,按照配送效率最高的原则进行配送方式优化,确定了各类物料的单件流、台套和两箱配送方式。 (3)按照不间断、不迂回、不倒流、不等待的原则,对物料按照配送属性进行分类分析,并对各类物料的配送路线进行配送路径优化设计,确定了不同类别物料的最优配送路线。论文综合探讨精益物流的相关理论如何在制造企业落地实施的方法,重点研究了制造企业结合企业发展的实际情况,灵活运用精益的思想,构建厂内物料库存控制和厂内物流配送体系并推动实施,对制造企业的精益物流推进有十分重要的借鉴意义。
[Abstract]:In order to adapt to the increasingly fierce competition environment, enterprises gradually adopt lean production mode characterized by short period, multi-variety and small batch mixed production. Lean logistics can adapt to lean production and effectively manage the material flow, information flow and labor force of the enterprise, and reach the goal of delivering qualified products to the designated position according to the quantity of demand at the right time. The pursuit of eliminating all waste, including inventory, so lean research on production logistics system is of practical significance. Based on the current situation of production and operation of L Company, this paper analyzes the six modules of lean logistics, which is based on the construction of production planning model. This paper puts forward two major problems in the current logistics management of the company: one is the excessive inventory caused by the unreasonable material ordering strategy, the other is the confusion and inefficiency of the distribution caused by the lack of systematic planning of the distribution mode and the distribution route. Based on the lean logistics concept, the paper makes a key research on inventory control and distribution of the company's production logistics: (1) constructing lean production planning model, under the premise of material requirement plan determination, The materials are classified by ABC according to value and variety, the premise of zero shortage is set up, the model is established according to the lowest principle of inventory cost, the design calculation and comparative analysis of class A and B materials are carried out, and the ordering strategy of all kinds of materials is determined. Achieve minimum inventory occupancy, minimum management costs to meet the goal of continuous flow production. (2) the materials are classified according to the shape characteristics, the distribution mode is optimized according to the principle of the highest distribution efficiency under the premise of satisfying the continuous flow production, and the single piece flow, table case and two boxes distribution mode of all kinds of materials are determined. (3) according to the principle of uninterrupted, uncircuitous, no backflow and no waiting, the material is classified and analyzed according to the distribution attribute, and the distribution route of all kinds of materials is optimized, and the optimal distribution route of different kinds of materials is determined. This paper comprehensively discusses the methods of how to implement lean logistics theory in manufacturing enterprises, and focuses on how manufacturing enterprises apply lean thinking flexibly in combination with the actual situation of enterprise development. It is very important for manufacturing enterprises to build material inventory control and logistics distribution system and promote the implementation of lean logistics in manufacturing enterprises.
