Modeling efficiently with GPSS/H

It is shown how modelers can use some of the powerful performance and ease-of-use features of GPSS/H to achieve the efficiency they need. It is pointed out that efficient modeling has two components. First, the simulation model itself should be as economical as possible in its use of computer time. Second, the modeling tool should contain features to ease the modeler´s burden when creating the model. Both components yield time savings, which can be used either to reduce the project budget or to do additional work within the original budget. The authors discuss ways in which GPSS/H contributes to both components. The following ways to achieve modeler efficiency are considered: using a 386 or 486 PC with interactive debugging; automation of experiments with the central statement language; using a smart random number generator; using macros; and building data-driven models
