SCHEDULING PROBLEMS - AN OVERVIEW

There seems to be a significant gap between the theoretical and the practical aspects of scheduling problems in the job shop environment. Theoretically, scheduling systems are designed on the basis of an optimum approach to the scheduling model. However in the practice, the optimum that is built into the scheduling applications seems to face some challenges when dealing with the dynamic character of a scheduling system, for instance machine breakdown or change of orders. Scheduling systems have become quite complex in the past few years. Competitive business environments and shorter product life cycles are the imminent challenges being faced by many companies these days. These challenges push companies to anticipate a demand driven supply chain in their business environment. A demand-driven supply chain incorporates the customer view into the supply chain processes. As a consequence of this, scheduling as a core process of the demand-driven supply chain must also reflect the customer view. In addition,

Decision Support Systems (DSS) development using a model of user inquiry types: Methodological proposals and a case study

A study of the DSS implementation area reveals an increased emphasis on methodologies for DSS development. As the DSS field matures, a larger number of methodological options are becoming available to the DSS developer. Existing methodologies have adopted various methods for performing the important task of DSS requirements analysis and specification. In envisaging a hierarchy of requirements analysis methods, a method for improved requirements analysis is proposed to remedy observed deficiencies within it. This method is based on a view of generic types of inquiries or solicitations made by the DSS user during decision-making. This formalism constitutes the basis of a proposed DSS development methodology that offers several benefits to DSS development. The intended benefits include a sharper and more focused requirements analysis to improve the DSS development process. This paper describes the model and methodology, alongside details of a real-world example of their use in developing a Marketing Decision Support System (MKDSS) for the support of marketing decision-making.     

大台井"川法"密集柱支撑力分析

从单体液压支柱的特性出发，结合大台井实际的煤层和顶板条件，计算了俯伪斜走向分段密集采煤法密集柱的支撑力。影响密集柱支撑力的相关参数主要有煤层厚度与倾角、采深、控顶距等。密集柱支撑力的大小随煤层厚度增加而增大，顶板压力主要由密集柱承担；随煤层倾角的增大而减小；随采深增加而线性增大，深部开采时应考虑适当增加支护强度；随控顶距增大而增加，但增加幅度较小。所得到的结论为大台井“川法”采煤的实施提供了理论依据。     

多专家集成式决策支持系统探讨

本文在文献[1]给出集成式决策支持系统(I—DSS)的基本概念及提出I—DSS的两种主要形式的基础上,对I—DSS的形式之一——多专家集成式决策支持系统(MEI—DSSS)作了较深入的探讨。本文阐述了MEI—DSS提出的原因,给出了MEI—DSS的基本概念,概述了MEI—DSS同相关学科和技术的关系,提出了MEI—DSS的基本结构框架,并从知识表示、推理机制以及多专家系统动态组合进行问题求解的算法实现等方面探讨了该系统在大型决策中的应用。本文最后提出了MEI—DSS今后有待深入研究的课题。
