Opis:: Dokonano przeglądu zastosowań systemów wspomagania decyzji w sektorze telekomunikacyjnym. Przedstawiono najbardziej reprezentatywne przykłady wykorzystania narzędzi komputerowych do wspomagania procesów decyzyjnych: hurtownie danych, analizę finansową i modelowanie matematyczne. Wskazano też perspektywy wspomagania decyzji w zarządzaniu strategicznym na przykładzie negocjacji umów, dotyczących połączeń międzyoperatorskich.
The paper outlines three types of using decision support in telecommunications. The first type relates to application of data warehousing based decision support systems. In the second part, application of various analytical modeling and analysis techniques for decision support is discussed. Conventional network planning techniques are based on single criteria optimization algorithms. However, single criteria optimization has its limitations. An overview of multicriteria analysis in designing telecommunication networks is therefore discussed as well as an application of the ISAAP module for this purpose. The paper outlines also, in the third part, some possibilities of using multicriteria analysis for supporting strategic decision related to negotiating interconnection agreements in telecommunications.

Opis:: Contrary to the common opinion, neural networks may be used for knowledge extraction. Recently, a new methodology of logical rule extraction, optimization and application of rule-based systems has been described. C-MLP2LN algorithm, based on constrained multilayer perceptron network, is described here in details and the dynamics of a transition from neural to logical system illustrated. The algorithm handles real-valued features, determining appropriate linguistic variables or membership functions as a part of the rule extraction process. Initial rules are optimized by exploring the accuracy/simplicity tradeoff at the rule extraction stage and the one between reliability of rules and rejection rate at the optimization stage. Gaussian uncertainties of measurements are assumed during application of crisp logical rules, leading to "soft trapezoidal" membership functions and allowing to optimize the linguistic variables using gradient procedures. Comments are made on application of neural networks to knowledge discovery in the benchmark and real life problems.

Opis:: This paper deals with life-saving decisions. The decision maker can buy a number of death-averting devices or services which increase his safety S at the expense of the discounted future consumption R. The safety and consumption depend parametrically on the death probability p and the probability reducing strategy x, i.e. S(p/x); R(p/x). The two-factors utility function U(S, R) is used to find the optimum strategy x = [...]. which maximizes U(x). One can show that the unique strategy [...] exists and can be effectively derived. Many applications of proposed methodology are indicated.

Opis:: In the perspective of parallel processing, a new sense of parametric optimization might be promoted. The paper shows that it, is possible to propose new parallel versions of basic optimization algorithms, as well as an advanced method of securing convergence in interactive mnltiobjective optimization and decision support, all based on a modified concept of parametric embedding. This general idea is exemplified for the case of the simplex algorithm of linear programming by a parameterized and coarse-grain parallel augmented simplex algorithm, where a linear optimization problem can be embedded into a multiple-ohjective family which introduces diversified directions of search cutting through the interior of the original admissible set. For the case of nonlinear programming, a parameterized and coarse-grain parallel variable metric pulsar algorithm is shortly presented, where parallel directional searches are combined with a parametrized variable metric to produce a pulsating, robust nonliear programming algorithm. These two examples concern very basic optimization tools ; at the other end of the spectrmn of optimization-related methods, a general method called outranking trials of securing convergence of interactive multiobjective optimization and decision suport is obtained through parameterizing an outranking relation and using basic properties of order-consistent achievement functions in reference point methodology for testing the existence of outranking points by parallel optimization runs. Thus, the paper presents the use of parallel processing to solve a wide range of modified parametric embedding problems related to optimization and decision support.

Opis:: The subject of this work is the defence planning of a point target against an air attack. The defence system is decomposed into a number of sectors. A direct method of coordination is used at the upper level, while the sectors use a discrete-time event-based model and the description of uncertainty by multiple scenarios of an attack. The resulting problems are solved using linear programming. A comparison of two coordination strategies for realistic attack scenarios and an analysis of effectiveness are provided.

Opis:: The expectation that computer networks combined with the Internet and associated technologies will be common in all businesses of the future has resulted in a flurry of investment in ICT around the globe, and in wide interest in the Internet, e-commerce and e-business. For example the Malaysian government has created a high-speed data highway, a federal capital that is a 'wired city', and a 'paperless hospital' [1]. The UK Government too has recently approved plans for major ICT projects [5, 10]. These projects are in healthcare, and involve large financial sums. It is important that the use of these public funds leads to successful outcomes. This paper analyses a large successful ICT project that uses e-business technologies. The aim of the paper is to identify the success factors in this completed project to see if these pointers indicate favourable prospects for the outcome of these new healthcare projects.

Opis:: In the paper an evaluation and optimisation framework for medical data access systems user interface is presented. User interface design seems to be of crucial importance for clinical data access applications acceptance, in particular for the applications running on handheld computers where the interface tools are significantly limited. The ease of program use depends strongly on the correct user interface design and on the algorithms which try to predict the user decisions and interactions made in the process of data access or modification. If the program is able to correctly predict the user actions and fetch him reasonable defaults then the number of interface actions which the user must do is significantly reduced. The method presented here focuses on typical functions available in clinical mobile data access systems: medication prescriptions and diagnostic and laboratory tests orders. The user interaction with an application is considered as the sequence of decisions. Using the records stored in the hospital database, the algorithm finds the most probable decisions at the subsequent stages of the interaction and uses it as defaults presented to the user. In this way instead of entering the data from the keyboard the user can much faster select it from the list.

Opis:: There are advantages in considering the routing problem in integrated communication networks as a multiobjective shortest path problem, having in mind to grasp eventual conflicts and trade-offs among distinct objectives and quality of services (QoS) constraints. On the other hand the utilisation of dynamic routing methods in various types of networks is well known to have significant impact on network performance and cost, namely in overload and failure conditions. This paper presents the detailed formulation of a proposal of a multiple objective dynamic routing method (MODR) of periodic state dependent routing type, enabling to represent distinct QoS related metrics and requirements in a consistent manner. The MODR method present formulation is based on a multiple objective shortest path model with constraints and is prepared to use implied costs as one of the metrics. Alternative paths tor each traffic flow are changed as a function of periodic updates of certain QoS related parameters estimated from real time measurements on the routes and trunks of the network. Such paths are computed by a specialised and efficient variant of a bi-objective shortest path constrained algorithm, developed for the MODR, enabling to incorporate flexible requirements on the QoS metrics. The architecture of the routing system is discussed together with the features of its main modules. An illustrative example of application of the MODR path calculation module to a circuit-switched type network using blocking probability and implied cost as metrics, is also presented, considering different overload conditions.

Opis:: The telecommunications operators have to manage one of the most complex systems developed by human beings. Moreover, the new technological developments, the convergence of voice and data networks and the broad range of services still increase this complexity. Such complex object as telecommunication network requires advanced software tools for their planning and management. Telecommunications operators collect large volumes of the data in various databases. They realize that the knowledge in these huge databases might significantly improve various organizational strategic and operational decisions. However, this knowledge is not given explicitly, it is hidden in data. Advanced methods and algorithms are being developed for knowledge extracting. In this paper we will focus on using data mining for solving selected problems in telecommunication industry. We will provide a systematic overview of various telecommunications applications.

Opis:: All definitions for integrated control agree that maximum emphasis should be put on prevention by using resistant cultivars and cultural measures. Moreover, the use of plant protection products should be limited to the essential minimum using Decision Support Systems (DSSs) that integrate and organise all relevant information. Computer-based DSSs that require weather information and regular late blight scouting inputs have been developed and validated in a number of European countries. In the frame of the EU concerted action “European network for development of an integrated control strategy of potato late blight (EU.NET.ICP)” several DSSs were validated in 1999-2001. The overall conclusion was that in most cases the use of DSSs combined a good disease control with a reduction of fungicide input. The DSSs can be used as a PC-version but more and more, parts of information are delivered to users by phone, fax, e-mail, SMS and websites on the Internet. An important task for the near future is to update the DSSs with information on the epidemiology of the new aggressive population of Phytophthora infestans. Issues such as (1) the influence of temperature and relative humidity on the infection process, (2) the role of primary inoculum sources (seed, oospores, volunteers, dumps), (3) the role of secondary inoculum sources (distance, severity), (4) control of early blight and (5) resistance ratings for foliar and tuber blight have to be addressed in order to be able to formulate a robust control strategy that effectively controls late (and early) blight with a minimum input of fungicides.
