An important issue in the management of urban traffic networks is the estimation of origin–destination (O–D) matrices whose entries represent the travel demands of network users. We discuss the challenges of O–D matrix estimation with incomplete, imprecise data. We propose a 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...

This paper extends a recent work that investigated a single-stage production-inventory model with reworks and planned backorders by fuzzifying its input parameters. The graded mean integration representation (GMIR) method, a useful and effective defuzzification method, is employed to develop a...

This paper develops a fuzzy multi-criteria game model of the competition between two arms exporting countries. The model permits multiple goals for the participants and anticipates a sizable degree of decision-making imprecision. The imprecision in the process is portrayed by fuzzy sets, the...

The increasing complexity in workflow management systems (WMSs) has led to greater vulnerability due to system failure. Although system vulnerabilities cannot be completely eliminated, the accidental or anticipated failures have to be thoroughly understood and guarded. Traditionally, the failure...

As most of the global economic activity takes place in the form of projects/programs, their effective management and governance is becoming more and more critical to the competitive position of organizations and societies. Project auditing and risk management, elaborate on methodologies that...

By now, there is a wide range of methods to construct multidimensional well-being indices, differing in the way they transform, aggregate and weight the relevant dimensions. This paper uses a fuzzy theory approach to propose a new weighting scheme for the dimensions. These weights play a crucial...

This paper discusses a manufacturing inventory model with shortages where carrying cost, shortage cost, setup cost and demand quantity are considered as fuzzy numbers. The fuzzy parameters are transformed into corresponding interval numbers and then the interval objective function has been...
