The methodology of risk calculation for project network techniques is presented. Development and research work is connected with uncertainty and risk. Many models for engineering design process are described in literature but it is necessary to develop a new one which would involve uncertainty....

Site selection plays an important role in the entire life cycle of solar thermal power plant (STPP) and the multi-criteria decision making (MCDM) methods are very important in the whole STPP site selection process. Some problems in the present MCDM methods decrease the evaluation quality of STPP...

Purpose – As the suppliers of any organization are considered as the strategic partners and taken as the integral part of the supply chain network, hence it is very crucial decision to select the suppliers in order to get the competitive edge. Whenever, any organization select its suppliers...

In conventional transportation problem (TP), supplies, demands and costs are always certain. In this paper, the author tried to categories the TP under the mixture of certain and uncertain environment and formulates the problem and utilizes the crisp numbers, triangular fuzzy numbers (TFNs) and...

The aim of this paper is to estimate the value of a fuzzy integral and to find the optimal step size and nodes via the stochastic arithmetic. For this purpose, the fuzzy Romberg integration rule is considered as an integration rule, then the CESTAC (Controle et Estimation Stochastique des...

The importance of correct and clear decisions during a complex and difficult situation is very easy to understand, but not so easy to achieve. Especially in situations where decision-makers must decide under time pressure and uncertainty. For instance, typical crisis situations have such...
