基于多目标的半导体生产线满意调度

在分析生产线性能指标的基础上，选择出用于优化的目标，并针对基于单目标的调度策略所存在的局限性，采用满意的概念，根据模糊规则与比较法提出了基于多目标的满意调度，实验表明该调度方法较单目标调度策略有很大的优越性，从而为实现生产线的整体优化提供了解决的途径。     

Partner selection model and soft computing approach for dynamic alliance of enterprises

Partner selection is an active research topic in agile manufacturing and supply chain management. In this paper, the problem is described by a 0-1 integer programming with non-analytical objective function. Then, the solution space is reduced by defining the inefficient candidate. By using the fuzzy rule quantification method, a fuzzy logic based decision making approach for the project scheduling is proposed. We then develop a fuzzy decision embedded genetic algorithm. We compare the algorithm with tranditional methods. The results show that the suggested approach can quickly achieve optimal solution for large size problems with high probability. The approach was applied to the partner selection problem of a coal fire power station construction project. The satisfactory results have been achieved.

Management of complexity in enterprise integration projects by the PERA methodology

The issue of the presentation and management of complexity is one of the most important aspects of the development and use of enterprise reference architectures and their associated methodologies. There is a limit to the degree of detail that any level of decision-making can comprehend adequately. As the breadth of vision of a decision expands the degree of detail must be correspondingly reduced. It is thus impossible to present every detail of any real world problem. The presentation has to be based on the principle of minimal complexity at any point. Therefore, the formalism of an enterprise reference architecture needs only to capture the most important factors at each stage of complexity. A hierarchical approach is thus inevitable. This article proposes a four-level formalism as a hierarchical model for use in further studies on the presentation of complexity management. These four levels include architectural, interface, design tool and semantic methods. The impact of complexity management on workflow design for enterprise integration is also discussed.
