物料需求计划（MRP）系统对于车间层，尤其是基于车间-工段-班组的车间层的作业计划和控制不是很有效的。本论文在回顾了传统的生产作业计划方法以后，首先提出复杂车间和简单车间的概念并分析了两类车间不同的生产组织方式，然后讨论了MRP系统的优缺点、在车间层应用的可能性和局限性以及优化生产技术（OPT）的概念和主要思想，提出了复杂车间环境下基于MRP和OPT的车间作业计划与管理系统的基本模型，在该模型中，本论文将车间作业计划与管理系统分为两层，MRP系统完成车间层计划功能，而用OPT思想进行工段层的计划和控制。在此基础上，本论文介绍了一个实例—大连机车厂机二车间车间作业计划与管理系统的基本思想、系统结构和流程以及部分软件模块的功能和工作过程。最后，在第四章，本论文对车间作业计划与管理系统开发中涉及到的软件技术进行了研究，并结合作者的实践针对系统设计和开发中系统体系结构的选择、系统开发方法和用Visual Basic（VB）开发应用程序时数据库访问技术的选择提出了建议。
MRP system is not very efficient in production planning and control of job shop, especially of the one that contains three-level structure: shop, subshop and workgroup. After reviewing the traditional methods of production planning, this paper firstly brought forward the concept of simple shop and complicated shop and analyzed the different production- organizing methods of them, then it discussed the advantages and disadvantages of MRP system, the possibility and the limitation of its application to the complicated shop, the main idea of Optimized Production Technology (OPT), and put forward the model of a MRP-OPT based j oh shop production planning and control system, in which MRP system is responsible for shop planning and control while OPT-based system for the planning and control of sub-shop. Based on this model, this paper discussed an example of a job shop production planning and control system used in JIR shop of DLRW by introducing the design thought, system structure, work flow and function of some software modules. Finally, this paper did some research on the software techniques involved in the system development and gave some suggestions on the system architecture, method of system development and database access method with Visual Basic based on the practices of the author.
