| 中文摘要 | 随着市场的不断变化及对产品个性化的需求，多品种中小批量生产方式已经成为制造业的发展主流，车间的计划与调度问题也变得越来越复杂化。传统的生产计划与调度模式是一种递阶结构分解方法，其存在的主要问题是计划调度决策脱节。车间计划调度集成问题需要从定性和定量两个方面的角度进行分析，定性的分析是对车间计划调度的业务过程、组织结构以及信息化管理下的各种活动或功能进行分析。定量的分析是从建立数学模型的角度对车间计划调度活动进行集成优化。车间计划调度集成问题可以从企业业务流程重构的角度出发，主要从过程模型集成、系统模型集成以及优化模型集成三个方面进行考虑和分析。本文所述的研究工作主要在如下几个方面： 1. 提出一种面向重构的业务流程再造的思想，作为这种思想的体现，提出了一种支持系统重构的车间建模体系，构建了基于资源整合的车间模型框架。分析、描述了车间模型框架的各个组成部分的概念和相互关系，阐述了建立基于资源整合的车间模型框架的原则、方法与步骤。 2. 通过分析IDEF与UML建模方法的优缺点，提出一种两者结合的系统建模方法，即用IDEF0模型进行系统需求分析，用IDEF1x模型指导关系型数据库系统的建立，用UML模型进行面向对象的软件系统设计。 3. 针对多品种批量生产类型建立考虑调度约束的生产计划与调度的集成优化模型。函数目标是使总的调整费用、库存费用以及生产费用之和最小，约束函数包括库存平衡约束和生产能力约束，同时考虑了调度约束，即工序顺序约束和工件在单机上加工的能力约束，调度约束的引入保证了计划的可行性。该模型为两层混合整数规划模型，综合运用遗传算法和启发式规则，提出了混合启发式求解算法。 4. 设计了系统基于Windows DNA的三层体系结构，归纳、总结了面向重构的系统组件设计方法、组件粒度划分原则以及XML技术在系统中的应用，进行了车间生产计划与调度系统的组件分类与划分。提出了混合启发式求解算法。最后针对沈阳第一机床厂的多品种批量生产类型车间进行了实例应用，对车间零件月份作业计划进行分解，得到各工段的单元零件周作业计划，确定了零件各周的生产批量与投产顺序。通过建立的基于资源整合的车间模型框架，理顺了业务过程，对关键组织结构进行了调整，取缔了原来繁杂的业务，实现了数据共享，提高了计划和调度的执行率，实现了对车间的生产计划、生产过程调度、产成品全面的管理。重构的业务过程提高了企业的效率，缩短了工作时间，增加了经济效益。根据提出的车间计划调度集成模型，针对沈阳第一机床厂的多品种批量生产类型车间进行了实例应用，对车间零件月份作业计划进行分解，得到各工段的单元零件周作业计划，确定了零件各周的生产批量与投产顺序。 |

| 英文摘要 | Traditional production planning and scheduling mode is hierarchical structure, its primary shortcomings include: production planning is extensive, without considering shop floor actual production capacity; scheduling level cannot feed back rate of progress to production planning level in due course; each manufacturing section is not in harmony with other departments, production planning mutual with locale schedule and other departments with small information, so planning cannot respond to changes, and changes cannot be fed back in time. Planner make shorter-period production planning, they generally confirm lot-sizes and sequence of putting parts into operation by experience, thereby induces in large work-in-process, infeasible planning and imbalance production. Traditional hierarchical plan decomposed in MRPII often results in infeasible plan for scheduling system for the reason that schedule restraints are not considered, new method to make planning must be adopted. The research includes content as follows: 1. Reconfigurable-Oriented Business Process Reengineering (for short ROBPR) is introduced. Indicates from Business Process Reengineering (BPR), ROBPR insists not only on radically “newly conceive, newly design and newly implement” for original business process, but also on strengthen variety adaptability (namely reconfiguration ability) of bushiness process, organize structure and reengineered information system. A shop floor model frame based on resource reconfiguration is constructed, and correlative methods are proposed. 2. The advantages and downsides of IDEF(Integrated DEFinition) and UML (Unified Modeling Language) are discussed. A method of modeling information system with both IDEF and UML was researched. The IDEF0 method is used to specify the information requirements, the IDEF1x models support modeling a relational database and the UML models aid to design an object-oriented software system. 3. An integrated optimization model of production planning and scheduling for batch production is introduced. Function objective is to minimize sum of total setup cost, inventory cost and production cost. Constraint functions include inventory balance, production capacity, as while as schedule constraints(procedure restriction and single machine capacity restriction). Feasible planning can be made with scheduling constraints considered. For solving the mixed integer programming model, a hybrid heuristic algorithm based on genetic algorithm and heuristic rules is developed. 4. A shop floor production planning and scheduling system based on components is introduced, related function models, system architecture, and components design method are recommended, finally system primary design techniques such as components classification, components partition and XML application are described. Integrated optimization production planning and scheduling model is used in a batch production shop floor of shenyang machine tool company. Cell weekly production planning of workshop section is set down by decomposing shop floor monthly production planning, and each item’s weekly lot-sizes and sequences of putting items into production are ascertained. |
