Abstract

This paper covers in detail the simulation model as well as the associated GPSS computer program of a complex queueing problem. Complexity is manifested in terms of the use of the model as well as the model itself. The former pertains to experimental design aspects. The latter, on the other hand, refers to structural considerations (i.e., parallel queueing systems sharing resources) as well as decision making behavior concerning the allocation of these scarce resources (i.e., a batch arrival and service queue with two different forms of balking and reneging). Following a general description of the model and program, a detailed presentation of the segment of code which represents decision making is made. Then several significant program highlights are discussed. Finally the technical considerations of the use of the program in a research investigation are described. The paper is intended for seasoned users of simulation. These may either be research investigators or simulation practitioners who at one time or another have been challenged to bring together the modeling requirements of their problem with the modeling capabilities of GPSS.
