2012 Vol. 18, No. 2 115--126
EN Managing occupational safety in any kind of industry, especially in processing, is very important and complex. This paper develops a new method for occupational risk assessment in the presence of uncertainties. Uncertain values of hazardous factors and consequence frequencies are described with ling[...]

EN When dealing with multi-criteria decision making problems, the concept of Pareto-optimality and Pareto-dominance may be inefficient (e.g. generally multiple solutions exist), especially when there is a large number of criteria. Our paper considers the fuzzy multi-criteria decision making problem bas[...]

PL W referacie przyjęto założenie, że rozkład możliwych terminów realizacji dostaw materiałów budowlanych i preferowane terminy ich przyjęcia na placu budowy sąmodelowane przez liczby rozmyte. Przedstawiono metodę analityczną oceny synchronizacji dostaw i zapotrzebowania na materiały budowlane z wykorz[...]
EN The paper assumes that spread of possible delivery time of building materials and theirs preferable delivery schedule on building site are projected by fuzzy numbers. Authors presented an analytical assessment method of deliveries synchronisation and demand on building materials with use of fuzzy nu[...]

EN Cluster analysis is a technique that divides a given data set into a set of clusters in such a way that two objects from the same cluster are as similar as possible and the objects from different clusters are as dissimilar as possible. In this background, different rough-fuzzy clustering algorithms [...]

EN Rough sets are often induced by descriptions of objects based on the precise observations of an insufficient number of attributes. In this paper, we study generalizations of rough sets to incomplete information systems, involving imprecise observations of attributes. The precise role of covering-bas[...]

EN This paper presents a fuzzy multi-objective decision model for a vertically integrated steel supply chain to produce and allocate scarce steel products among a set of alternative distribution channels based on their past performances. The objectives include net profits, inventory costs, backorder am[...]

EN A new approach to risk assessment in the portfolio selection optimization problem in a fuzzy setting is presented. The approach is based on the a-level representation of fuzzy values describing the stock's returns. The two-objective method based on the weighted lower and upper bounds of fuzzy portfo[...]

EN Gathering reliability data is quite difficult. Potential sources of such data are: reliability guides and handbooks, data collecting during operation of technical devices, expert judgments. Practice shows that very often the statistical sample we have to our disposal is small and non – homogenous. T[...]

EN In the paper the theory of fuzzy sets is discussed from the standpoint of theory, and the concept of fuzzy reliability, the fuzzy mean value of the time up to a failure and the fuzzy failure rate are defined. The mathematical method used is also specified. Subsequently, this mathematical method is a[...]

EN BZMVdM algebras are introduced as an abstract environment to describe both shadowed and fuzzy sets. This structure is endowed with two unusual complementations: a fuzzy one \lnot and an intuitionistic one ~ . Further, we show how to define in any BZMVdM algebra the Boolean sub-algebra of exact eleme[...]

EN An industrial gauge for measuring thickness of a gold coating layer deposited on a steel base through detection of the backscattered beta particles has been described. 3H, 14C and 63Ni pure beta emitters have been tested as the radioisotopic sources of the system individually in a fixed geometry. An[...]

EN The paper presents a proposal of a new methodology that evaluates multicast routing algorithms in packet-switched networks with an application of fuzzy sets. Proposed multicriteria mechanism evaluate representative multicast routing algorithms: KPP, CSPT and MLRA (Multicast Routing Algorithm with La[...]

EN In present issue the technique of adequate precise valuations of financial parameters of the investment based on the method of multiobjective optimization in the case of initial data presented as the fuzzy-intervals is offered. The final results obtained as the compromise between criteria of a profi[...]

EN We outline the relationship between classical (orthodox) sets from one side, and fuzzy and rough (non-orthodox) sets from another side. The classical concept of a set used in mathematics leads to antinomies, i.e., it is contradictory. This deficiency has, however, rather philosophical than practical[...]

EN The article outlines how to use the convergence of collections to determine the position of a mobile device based on the WiFi radio signal strength with the use of fuzzy sets. The main aim is the development of the method for indoor position determination based on existing WiFi network infrastructur[...]

EN Data used in machine learning applications is prone to contain both vague and incomplete information. Many authors have proposed to use fuzzy rough set theory in the development of new techniques tackling these characteristics. Fuzzy sets deal with vague data, while rough sets allow to model incompl[...]

EN This paper presents recent approaches in soft computing to manage imprecision and uncertainty which appear in software reliability engineering. Firstly, recent approaches like imprecise probabilities, generalized intervals, fuzzy sets and intuitionistic-fuzzy sets are shortly described, and the usag[...]
