The paper describes the necessity of application of intelligent technologies to support decisions of more objective problems in human resource management. In this paper, we describe the methodology for personnel selection problem for the vacancy with regard to the importance and nonequivalence of numerous indicators characterizing the alternatives. The specific features of the selection problem are highlighted, immersing the problem into a fuzzy environment. A fuzzy multicriterial model of the personnel selection problem is proposed. A technique of order preference by similarity to ideal solition (TOPSIS), was applied for evaluation and regulation of alternatives. This technique is based on criteria of qualitative character, which are hierarchically structured by multiple experts to intellectually support decisions made in personnel selection problem. Using TOPSIS method and generated criteria system an experiment was conducted for evaluation of the candidates during solution of hiring problems. The obtained and reviewed results were compared with results obtained using in reality. 展开更多

It lacks adequate water supply. Being a State Capital, rapid improvements in itsinfrastructures including water supply to cope with increased demands are required. Three options forthe expansion of the present water supply system are been considered. These are Groundwater resourceswithin and around the existing system, and surface water schemes from two Dam sites identitied andappraised for this purpose. The Management of the Yobe State Water Board and the State Governmentare faced with the problem of which of these three options to choose. This is a typical capacity expansionproblem within a multicriterion setting in which the choice is to be bassed on economic, environmental,social as well as political considerstions. This paper presents a multicriterion analysis whose result willbe used in forming the basis of an informed decision to be made on why a particular option is to bechosen. 展开更多
