In this paper we study cooperative games with fuzzy payoffs. The main advantage of the approach presented is the incorporation into the analysis of the problem of ambiguity inherent in many real-world collective decision situations. We propose extensions of core concepts which maintain the fuzzy...

When dealing with multi-criteria decision making problem the concept of Pareto -optimality and Pareto-dominance could be inefficient (the lack of unique solution), especially with many number of criteria. Our paper faces the fuzzy multi-criteria decision making problem based on Zadeh’s...

Health-care waste (HCW) management is a high priority public health and environmental concern particularly in developing countries. The decision to select an optimal technology for the disposal of HCW is a complicated multi-criteria decision analysis problem involving both qualitative and...

This paper examines the links between corporate funding, co-operative industrial relations, and wage flexibility, on the one hand, and economic growth, on the other, in 11 countries in South Eastern Europe. These links have been downplayed in previous research. The paper draws on the most...

Estimating exact probabilities of occurrence of fault events for use in the conventional fault tree analysis (FTA) is difficult when failure data are insufficient or fault events are imprecise such as human error. A hybrid approach employing fuzzy sets and possibility theory is proposed to...

We analyze a decomposition of the fuzzy numbers (or intervals) which seems to be of interest in the study of some properties of fuzzy arithmetic operations and, in particular, in the analysis of fuzziness, of shape-preservation (symmetry) and distributivity of multiplication and division. By the...

The LU-model for fuzzy numbers has been introduced in [4] and applied to fuzzy calculus in [9]; in this paper we build an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy representation and to show the advantage of the parametrization. The calculator produces the basic fuzzy...

In this paper we illustrate the LU representation of fuzzy numbers and present an LU-fuzzy calculator, in order to explain the use of the LU-fuzzy model and to show the advantage of the parametrization. The model can be applied either in the level-cut or in generalized LR frames. The hand-like...

For construction activities, timely resource allocation is crucial to avoid unnecessary waiting time of resources and delay of activities, especially under the condition of limited supply of resources. Timely resource allocation, i.e. determination of an activity that has the highest priority to...

This paper examines the role of the interest rate in investment decisions for firms in Taiwan. To reflect the human side of decision making and the uncertain nature of information provided, we employ fuzzy set theory and fuzzy logic to examine the nonlinear relationship between these two...
