This paper reviews the dominant approaches to the design of decision support systems with reference to recent developments in information technology. The complexities and difficulties of the various developments are also discussed and their implications explored. A multiperspective, systems-based framework is presented which aims to lessen these difficulties. The framework is based on the theory and concepts of critical systems thinking.  相似文献

This paper reviews earlier work on the validation of mathematical models and modeling within Decision Support Systems (DSS), in particular where the DSS were developed to support operations management. The authors found that little validation was carried out in practice. With this work as a base, reasons for the paucity of validation are advanced and comparisons with DSS developed to support marketing management are made. The case for a more appropriate methodology of validation is advanced.  相似文献

The purpose of this research is to introduce the basic concept of multiple-criteria decision support systems (MCDSS) and to provide a general framework for building an effective MCDSS, a powerful tool for managing complex, unstructured decisions. Although various techniques for multiple-criteria decision making (MCDM) have been developed, this paper investigates the functions and properties of goal programming model-based MCDSS, the role of decision makers and MCDM models in the decision-making process, and the dynamic interaction between the model and the decision maker. The potential benefits of the MCDSS are also explained.  相似文献

1. INTRODUCTION Decision Support System(DSS) was presented by Scott Morton in his paper entitled as “Management Decision Systems” in the early 1970’s. Until the 1980’s, DSS had become a new interdiscipline involved computer science, operational research and managerial science. The definition for DSS presented by Gorry and Scott Morton is that DSS combines personal resources with computer’s abilities so as to improve the quality of decisions. And it is an assistant system bas…  相似文献

Tool management is not a single, simple activity, it is comprised of a complex set of functions, especially in a flexible manufacturing system (FMS) environment. The issues associated with tool management include tool requirement planning, tool real-time scheduling, tool crib management, tool inventory control, tool fault diagnosis, tool tracking and tool monitoring. In order to make tools flow into/out of FMS efficiently, this work is aimed to design a knowledge-based decision support system (KBDSS) for tool management in FMS. Firstly an overview of tool management functions is described. Then the structure of KBDSS for tool management and the essential agents in the design of KBDSS are presented. Finally the individual agents of KBDSS are discussed for design and development.  相似文献

Executives who consider the acquisition of Executive Information Systems (EIS) may encounter several major problems already in their selection and introduction stages. Key issues are the following: Can the EIS's really match our managerial needs and support decision making in our organizational contingencies? How widely in the leadership levels can they be introduced? Are they easy-to-learn, easy-to-use and easily customizable? Do they utilize the newest information technology, e.g. graphics and modern interface technology? Can they work in our computer network? In order to facilitate elegant solutions of the selection problems, we construct an evaluation framework which guides the selection of an EIS product to match the managerial needs according to the organizational contingencies. This framework is useful immediately after the specification of the decision making support requirements of the executive. The effectiveness of the framework is shown by applying it and analyzing 13 EIS products. We also offer introduction and use experiences from four English and four Finnish large companies covering the opinions of 132 EIS users. In this paper we give general answers to the questions above and discuss other relevant issues.  相似文献

The support vector machine (SVM) is a novel machine learning method, which has the ability to approximate nonlinear functions with arbitrary accuracy. Setting parameters well is very crucial for SVM learning results and generalization ability, and now there is no systematic, general method for parameter selection. In this article, the SVM parameter selection for function approximation is regarded as a compound optimization problem and a mutative scale chaos optimization algorithm is employed to search for optimal paraxneter values. The chaos optimization algorithm is an effective way for global optimal and the mutative scale chaos algorithm could improve the search efficiency and accuracy. Several simulation examples show the sensitivity of the SVM parameters and demonstrate the superiority of this proposed method for nonlinear function approximation.  相似文献

为提高支持向量机(support vector machine, SVM)算法对大规模数据的适应能力,加快SVM算法的分类速度,提出一种基于决策树的快速SVM分类方法。该方法的重点在于构建一棵决策树,将大规模问题分解为相对简单的子问题,树中节点由线性支持向量机组成,每个节点包含一个决策超平面,分类过程取决于节点的数量。此方法在分类复杂样本时避免了使用非线性核函数。并且由于使用线性核函数,则不用进行模型选择,进一步加快了样本的分类速度。实验表明,针对大规模多特征数据的非线性分类问题,该方法比传统方法具有更高的速度。  相似文献
