A Study on Fuzzy Decision Problem of a Queueing System with Finite Capacity by LR Method

Main Article Content

S. Vijaya, et. al.


In this paper, LR method has been proposed to mathematical non-linear parametric programming approach for the queueing decision problem.  Using LR method, the minimal expected total cost of a crisp queueing system with finite capacity using LR – type trapezoidal fuzzy numbers is calculated.  LR method is simple, short and convenient compared to alpha-cut method.  Numerical example is illustrated for comparison between alpha – cut method and LR method.
