Simulation of Railway Marshalling Yards Based on Four-Phase Queuing Systems,ese objects are key elements for the organization of freight transport on the railway network. In this work, we develop a mathematical model for the operation of a marshalling yard in the form of a four-phase queuing system with . flow and group service of requests. Each phase is a non-Markov multic

Numerical Methods to Analyses of Queuing Systems with Instantaneous Feedback, Positive Server Setuposed. Arrival rate of calls from outside depends on server status which might be in two regimes: working regime and setup regime. Calls are impatient when server is in setup regime. Two approaches are developed to study the system: matrix-geometric method and space merging method. Results of numeric

,On a Single Server Queueing Inventory System with Common Life Time for Inventoried Items,low Phase type(PH) distribution. An inventory of commodities is attached to the service station. The common life time (CLT) for inventoried items is assumed to follow Phase type(PH) distribution. The inventoried items perish all together. In this case, the supply of items is immediately in local pur

Infinite Markings Method in Queueing Systems with the Infinite Variance of Service Time,e analyzed. In queueing systems without priority the stationary average queue length is infinite when the service time has infinite variance even if the utilization is less than one. In case of Poisson arrival flow and Pareto distributed service times with finite mean and infinite variance, the stat
