Developing decision support for dialysis treatment of chronic kidney failure.

The complexity, variability, quantitative nature, and data density of treatment for chronic kidney failure make dialysis information systems excellent candidates for computerized decision support. We describe the development of an intelligent system building on existing knowledge and susceptible to reconfiguration on the basis of knowledge acquired during the use of the system. Various decision support techniques were used to design and develop the decision support modules. This paper briefly reviews the literature on clinical decision support, discusses some of the problems faced by practitioners in managing chronic kidney failure (end-stage renal disease) patients, and sets forth the decision support techniques used in developing a dialysis decision support system.     

A Multi-Agent System to Support Location-Based Group Decision Making in Mobile Teams

This paper describes an agent-based approach for developing a location-based asynchronous group decision-support system for mobile teams. The approach maximises the use of reusable service components (GSCmas — generic service component for multi-agent systems) as the main interaction mechanism between agents to allow flexible support of a new group-decision process. The paper describes the architecture of a GSCmas and provides details of how the GSCmas is integrated within a decision support system. Finally a system (mPower) based on the proposed approach is introduced and applied to a location-based group decision problem.

A process model of make-vs.-buy decision-making. The case ofmanufacturing software

The decision to develop (make) a product or process internally or to purchase the relevant technology (buy), an issue facing many organizations, is discussed. What has been written about make-vs.-buy decisions usually consists of generic checklists of dubious relevancy to the decision maker's specific situation. Development of a process model based on a class of such decisions is therefore desirable. In-depth cases studies in seven organizations were conducted, guided by a series of key issues pertaining to the process of strategic decision making. Experience gained at eight other sites added to the analysis and development of a model. The study has found that make-vs.-buy decisions are treated in various ways. Of special interest is the recognition, in some organizations, of make-vs.-buy decisions as opportunities to develop or support competitive advantage. In such firms, the entire approach and decision-making style are oriented towards achieving such an advantage     

Global Scope at the National Level: The ITU's Contributions to Telecommunications Development

The International Telecommunication Union's (ITU) work that is oriented towards the needs of developing countries is described. This work is explained as one of two kinds of technical cooperation; the other kind corresponds to the ITU's traditional function as coordinator and standards-maker for international working of telecommunication services. It is shown how these two kinds of technical cooperation both aid each other and compete with each other for funds, top-level organizational attention, and provision of expert manpower. The growth and diversity of cooperative activities for the benefit of developing countries is reviewed in some detail. Numerous examples of handbook-writing and special national or regional projects are given. It is concluded that the ITU exhibits two faces, one directed toward the highly developed country, another toward the developing country in need of help. Maintaining a judicious balance in support of these two personalities represents a challenge to the ITU as a whole, and to its Permanent Organs in particular.

A Gen-Fuzzy Based Strategy (GFBS) for Web Service Classification

Service oriented computing makes great growth in developing web services. A web service is a software application with a standardized way of providing interoperability between disparate applications. Web service repository has a main challenging task in how it can help end user and another web service to group and retrieve their service with high performance. With increased number of both unrestricted and distributed services in web that belong to different domains, web services classification become necessary. This paper proposes a new classification strategy for web services called Gen-Fuzzy Based Strategy. The proposed strategy consists of two stages, which are; (i) Outlier Rejection Stage (ORS) and (ii) Classification Stage. In ORS, a proposed fuzzy system has been presented. It used four parameters which are; Distance to Class Center, Cooling Force, Class Belonging Degree and Domain Belonging Degree. In CS, a proposed Distance Based Ensemble Classifiers (DBEC) has been presented. The aim of DBEC is to train each individual classifier independently by using bagging technique. A collective decision is made by their aggregation in several ways. Experimental results have shown the effectiveness of DBEC in terms of accuracy, precision and recall.
