【摘要】 目前,国内大多数生产计划系统只针对某特定生产类型的制造企业,但由于不同生产类型的制造企业往往在生产组织方式和管理的重点上均会存在差异,因而,这些生产计划系统普遍存在计划形式单一、计划编制不规范和系统可控性低等问题。制造业类型的多样性以及生产过程的可变性要求生产计划系统的体系结构具有很强的灵活性,不仅能适应不同生产类型企业的运作模式,还要具备支持企业在内部流程和外部环境发生变化时快速地进行系统重构的能力。因此,以企业资源计划(Enterprise Resource Planning,ERP)理论为基础,结合现代生产计划管理技术与信息技术,设计和开发面向多种生产类型、具有可重用性的生产计划系统具有非常重要的理论和实践意义。论文首先介绍制造业信息化的发展现状,阐述了ERP国内外开发与应用现状和存在的主要问题。随后,介绍了生产管理理论及现代生产管理模式,以及构件技术和工作流管理技术。本文分析了不同类型的制造业生产模式的特征以及对软件体系结构的需求,提出了可重构的生产计划体系结构的总体框架,并提供基于工作流技术分析生产计划系统流程的方法,利用Petri网进行业务过程建模,使建立的业务流程模型能方便系统根据企业运作方式的更改作出调整。此后,论文对生产计划系统的功能模块及相关技术进行了详细设计,核心模块主要有基础数据管理模块、主生产计划模块、物料需求计划模块及能力需求计划模块。在基础数据模块中详细设计了可重构的BOM;在主生产计划模块中提供了多种计划方式和对应的关键算法;在物料需求计划模块,研究了柔性提前期及批量问题;能力需求计划模块主要用于分析产能与需求是否平衡的问题。最后详细设计了系统数据库、实现业务流程重构和功能模块重构的方法以及部分关键问题的实现技术。论文以哈尔滨锅炉厂有限责任公司和哈尔滨轴承集团公司为背景作了实证研究,证明了所提出的可重用体系结构的有效性和系统面向不同生产类型制造企业的通用性。更多还原

【Abstract】 Most of the existing Production Planning Systems (PPS) of China, currently, are designed for special type of manufacturing firms. But when concerning the modes of production and styles of management, the different manufacturing firms have distinct features that differ amongst them. Hence, it should be appropriate to conclude that most traditional PPS lack variety and standard for plan-making and thus embody low-controllability of the system. In fact, the type diversity and changeability of the manufacturing firms require general PPS with flexible structure which can adapt to different types of manufacturing firms and facilitate fast reconfiguration while internal workflow and external environment may keep changing. So, it is of utmost significance from the viewpoint of both theory and practice to design and to develop a kind of multi-type oriented PPS in the general framework of Enterprise Resource Planning (ERP) which integrates advance technology of production planning management and information technology.This thesis attempts, first, at making an investigation of informationisation of the manufacturing industry and application of ERP system, and sums up by examining the problems of ERP that currently exists. Then it introduces production management theory and modern production management models. It introduces further the component technology and workflow management technology. Further it analyses the characteristics of production manner of different types and corresponding requirement of software structures and proposes the framework of the reconfigurable PPS. Further yet, a method for analysing the PPS flow according to workflow technology has been introduced and in this Petri net introduced whose aim is at modelling business processes for more flexible modification. Subsequently a design of the functions of PPS has been introduced as well as details of relative techniques. There are four main function modules in the PPS, namely basic data module, Master Production Schedule module (MPS), Material Requirements Planning module (MRP) and Capacity Requirements Planning module (CRP). In basic data module, a reconfigurable BOM has been designed. MPS has been designed to provide different method of planning. Targets of MRP have been designed to focus on problems about flexible leading time and batch production. Balance status between production capability and capability has been made to be concerns of CRP. Subsequently, it discusses in detail the design of the database of PPS and the method for implementing the reconfiguration of business process and function modules.Finally the thesis presents a case study of Haerbin Boiler Factory Ltd., and Haerbin Bearing Group Co., which demonstrate the availability of the reconfigurable characteristic of PPS and its universality for different types of manufacturing firms.更多还原
