The Distribution System Simulator (DSS) is a software system designed to overcome the difficulties inherent in the construction and use of simulation models for large-scale, physical distribution systems. The central difficulties associated with the simulation of a distribution system are: (1)...

It is common for matrices in industrial applications of linear programming to have a large proportion of zero coefficients. While every item (raw material, intermediate material, end item, equipment item) in, say, a petroleum refinery may be indirectly related to every other, any particular...

The SIMSCRIPT programming system is especially designed to facilitate the writing of simulation programs. Digital simulations generally consist of a numerical description of "status," which is modified at various points in simulated time called "events." SIMSCRIPT simulations consist primarily...
