This paper includes a simulation model built in order to predict the performance indicessuch aswaiting time by analyzing queue’s components in the real world under uncertain and subjective situation. The objective of this paper is to predict the waiting time of each customer in an M/M/C queuing model. In this regard, to enable decision makers to obtain useful results with enough knowledge on th...

This technical support center is vital to Macrohard’s business strategy, since it has a significant impact on customers’ experience with their products. To ensure that this experience is positive, technicians must provide accurate information and helpful support. From Macrohard’s perspective, this is a matter of ensuring that the technician has the right skill and training. But for customers to...

queueing is a package that solves and provides the main performance measures for both basic Markovian queueing models and single and multiclass product-form queueing networks. It can be used both in education and for professional purposes. It provides an intuitive, straightforward way to build queueing models using S3 methods. The package solves Markovian models of the form M/M/c/K/M/FCFS, open...

The alternating renewal process is one of the renewal processes in renewal theory. It is widely used in inventory systems and queueing systems. In classical alternating renewal processes, one of the assumptions is that the on times and off times are independent random variables. The notion of a fuzzy set was introduced by Zadeh [1] who defined it as a generalized characteristic function. Recent...

In this chapter, we utilize L–R method to calculate the parameters of performance fuzzy Markovian queueing system FM/FM/1 in transient regime. The technique calculating used is arithmetic numbers restricted secant approximations. membership function has helped us represent graphically curves into space three dimensions regime environment. An illustrative example given medical field show relevan...
