On retrial queueing model with fuzzy parameters

Ke, Jau-Chuan; Huang, Hsin-I; Lin, Chuen-Horng - In: Physica A: Statistical Mechanics and its Applications 374 (2007) 1, pp. 272-280

This work constructs the membership functions of the system characteristics of a retrial queueing model with fuzzy customer arrival, retrial and service rates. The α-cut approach is used to transform a fuzzy retrial-queue into a family of conventional crisp retrial queues in this context. By...

Neighbourhood Search for constructing Pareto sets

Dorini, G.; Pierro, F.; Savic, D.; Piunovskiy, A. - In: Mathematical Methods of Operations Research 65 (2007) 2, pp. 315-337

This paper describes theNeighbourhood Search, an effectivemethod that we suggest for constructing Pareto sets in multiple objective problems with conegenerated orders. TheNeighbourhood Search is then applied to discounted Markov Decision Processes, resulting in original statements about...

A BRANCH-AND-BOUND ALGORITHM FOR FINDING ALL OPTIMAL SOLUTIONS OF THE ASSIGNMENT PROBLEM

FU, ZHUO; EGLESE, RICHARD; WRIGHT, MIKE - In: Asia-Pacific Journal of Operational Research (APJOR) 24 (2007) 06, pp. 831-839

Alternative optimal solutions can give more choice for practical decision making. Therefore, the provision of methods for finding alternative optimal solutions is an important component part of the solution techniques for optimization models. The aim of this paper is to present a...

FUZZY LINEAR PROGRAMMING APPROACH TO MULTI-ATTRIBUTE DECISION-MAKING WITH LINGUISTIC VARIABLES AND INCOMPLETE INFORMATION

LI, DENG-FENG; SUN, TAO - In: Advances in Complex Systems (ACS) 10 (2007) 04, pp. 505-525

The aim of this paper is to develop a new fuzzy linear programming technique for solving multi-attribute decision … ideal solution (FIS) which is unknown a priori. Then the FIS and the weights of attributes are estimated using a new linear … programming model based upon the consistency and inconsistency indices defined. The fuzzy distance of each alternative to the FIS …
