On Transportation System with Deterministic Service Time

Most of transportation systems behave as M/D/1 queuing type which is widely explored throughout scientific literature.On the other hand , there are a few real life examples of transportation systems with deterministic service time.In this paper we explore one of such systems and propose solution finding for tactical port operational problem by queuing model and heuristic method.A heuristic approach is developed as an alternative to mathematical model solution finding.Between these two methods , good solutions of known quality are provided quickly.Through simple example of bulk loading terminal , defined as M/D/1 system , comparision of the heuristic solutions to the mathematical model indicates that the corresponding results match closely.On the basis of the experiment , we assume that the same heuristic with a slight modification would give acceptable solution for a real life M/D/S problem where search for feasible solution by mathematical model is a tough and unacceptable task in practical use.
