Due to the increase in the variety of demands from downstream customers, companies are required to expand their production capacity by way of adding more plants. Many enterprises encounter difficulties in production planning because manufacturing environments have changed from traditional single-plant to current multi-plants. Therefore, the production planners must develop an integrated multi-site planning approach to coordinate all production resources of multiple plants within the enterprise. As the company may possess many manufacturing plants that are located in different places geographically, the planners will face production allocation problems in the multi-site environment. The decisions may involve the manufacturing routings of demand products and production quantities among multi-plants. As a result, a monolithic model of the multi-stage and multi-site production planning problem is proposed in this paper. The contribution of this planning model is to combine two different time scales, i.e., monthly and daily time buckets. In addition, we also consider other practical planning characteristics and constraints. For example, production transformation functions, capacity consumption constraints, materials supplying constraints, inventory balancing equations and so on. Through optimization procedures, the information on production and procurement in the multi-plant network is derived. Besides, an example from a thin film transistor- liquid crystal display (TFT-LCD) manufacturer case in Taiwan is illustrated for explaining the monolithic planning model. 相似文献

The enormous growth in manufacturing automation has produced a plethora of advanced manufacturing technologies (AMTs) with diverse features. These AMTs could consist of semi- and fully automated systems or equipment. Manufacturing companies are seeking ways to gain a competitive edge over their competitors by investing in AMTs, where the ability to make rational choices among these AMTs is important for success. Integration of AMTs in an enterprise brings many islands of automation into a single database-shared entity. Effective integration by efficient communication links among these AMTs will generate significant benefits across many traditional functional units, eliminate many functional barriers, and provide opportunities to achieve the competitive goals. The effect of synergy caused by the integration of AMTs will have an impact on various functional units of the enterprise. This paper provides a methodology, firstly to identify appropriate technologies for a company based on their strategic focus, and secondly to estimate the functional interrelationships within the framework of a unified approach for the justification of computer integrated manufacturing (CIM). These derived functional interrelationships are utilised to assess the effect of synergy in an integrated enterprise and identify the optimal capital investments in AMTs as system components of CIM. 相似文献

在网络化制造模式下,由于扩展企业涉及的制造资源在地理上和所有权上具有很大差异,使得制造信息从底层制造设备、制造单元,到高层的制造车间、盟员企业和核心企业的共享不够及时和准确,制造信息的保护也不够完善。为此,本文提出了一种企业核心制造资源信息保护策略,采用ANP(Analytic Network Process-网络分析法)算法针对制造执行过程中产生的各类制造资源信息进行重要度和可视度分类决策,在此基础上,企业以模板的形式向相关用户提供制造资源信息共享服务。最后,本文通过实例对所开发的原型系统进行了例证。 相似文献

The effective generation, sharing and re-use of innovation knowledge play an increasingly crucial role in the competitiveness
of industrial enterprises allowing the companies to offer new solutions based on rapidly exploited innovations. As the innovation
knowledge is by its nature very unstructured and manifold in its definition, solutions for effective exchange and sharing
of such knowledge within collaboration networks of extended enterprises are still missing. This paper presents a set of new
methods and IT tools to support efficient and smooth exchange of innovation knowledge in extended and networked enterprises.
The methods and tools are based on so-called hybrid approach in definition of ontologies needed as a basis for knowledge sharing
within a network of companies. The developed tools enable efficient set-up, harmonisation and maintenance of generic, shared
ontologies. The solutions are tested within a large manufacturing enterprise involving several subsidiaries. 相似文献
