面向项目制造的复杂装配过程资源建模

面向订单设计(engineering-to-order,ETO)制造企业由于其产品结构复杂,对制造过程的组织管理不同于一般产品的装配制造。在单件小批生产模式的基础上,采用项目管理方法满足复杂产品制造过程特征要求,建立面向产品最终装配的项目制造(project-based manufacturing,PM)计划管理模式。面向项目制造的分层网络计划方法将生产计划的对象从零部件转换为具有一定缓冲空间的装配单元,建立整个装配过程的资源-任务矩阵,实现资源与任务的关联以及资源负荷的追溯,为实现以项目产品为对象的计划与资源的匹配提供数据支持。

Manufacturing resource modeling of complexassembly process under project-based manufacturing

In an engineering-to-order (ETO) company, organization and management of manufacturing process is differ from common products because of the complexity of product. A project-based manufacturing (PM) planning model for product final assembly is proposed based on single-piece and small-batch production model so that the characteristics of complexity, specificity and high complex product manufacturing process can be met by means of projected-based manufacturing. The method of layered network planning under project-based manufacturing can transform the objects of planning from parts to assembly cell in the course of final assembly that has some time-based buffer for planning; simultaneously a resource-task matrix is build for the whole assembly process. The matrix can achieve the relatedness between manufacturing resources and assembly task, and follow the resources loads in order to realize the matching of planning and resource against project product.
