在复杂装配线生产过程中,如何实现物料的按时有序配送和关键零部件的齐套控制是物料配送管理的主要难题.在分析产品装配结构、装配工艺流程以及物料配送规则的基础上,通过梳理“制造BOM—作业BOM—配送BOM”之间的转换映射关系,建立基于装配工艺流程的作业BOM生成方法和基于工位结构分解的配送BOM生成方法,实现对复杂装配生产线物料配送信息的一致性映射和完整性控制,为物料配送的精细化管理提供能够反映装配作业过程特征的数据描述模型.最后通过应用实例验证说明上述BOM转换映射技术的合理性和可行性. 相似文献

Organizing and managing dynamic networks of enterprises (or virtual enterprises (VE)) is a very complex task and many issues are still to be effectively covered. Apart from the models that can be used to create and manage VEs, product data play a central role in the VE life cycle. VE composition, interaction among VE members (Autonomous Production Systems in this work), as well as its relationship with the market, is severely dependent on the product technical specifications as well as on the product process planning information. In traditional managing systems for the single enterprise environment the Bill of Materials (BOM) plays that role and in this paper is proposed a Bill of Materials and Movements (BOMM) as its equivalent in VE environments. The BOMM includes product structure, high level process planning information and some degree of VE composition. BOMM is present during VE formation, operation, and reconfiguration, playing a central role in the material detailed planning and in the movement planning between VE members. In this article the BOMM role during the VE life cycle is described in detail. 相似文献

In the big data environment, enterprises must constantly assimilate big data knowledge and private knowledge by multiple knowledge transfers to maintain their competitive advantage. The optimal time of knowledge transfer is one of the most important aspects to improve knowledge transfer efficiency. Based on the analysis of the complex characteristics of knowledge transfer in the big data environment, multiple knowledge transfers can be divided into two categories. One is the simultaneous transfer of various types of knowledge, and the other one is multiple knowledge transfers at different time points. Taking into consideration the influential factors, such as the knowledge type, knowledge structure, knowledge absorptive capacity, knowledge update rate, discount rate, market share, profit contributions of each type of knowledge, transfer costs, product life cycle and so on, time optimization models of multiple knowledge transfers in the big data environment are presented by maximizing the total discounted expected profits (DEPs) of an enterprise. Some simulation experiments have been performed to verify the validity of the models, and the models can help enterprises determine the optimal time of multiple knowledge transfer in the big data environment. 相似文献

This paper presents a modern approach to integrated development of Unmanned Aerial Vehicle made of laminated composite materials from conceptual design, through detail design, strength and stiffness analyses, definition and management of design and production data, detailed tests results and other activities related to development of laminated composite structures with main of its particularities in comparison to metal structures. Special attention in this work is focused to management processes of product data during life cycle of an UAV and experimental tests of its composite wing. Experience shows that the automation management processes of product data during life cycle, as well as processes of manufacturing, are inevitable if a company wants to get cheaper and quality composite aircraft structures. One of the most effective ways of successful management of product data today is Product Life cycle Management (PLM). In terms of the PLM, a spectrum of special measures and provisions has to be implemented when defining fiber-reinforced composite material structures in comparison to designing with metals which is elaborated in the paper. 相似文献
