The Combination of Alternative Research Techniques in Logistics Systems Analysis.
An examination of the nature of systems analysis, and of past experiences with it, to help develop a strategy for selecting appropriate techniques. To facilitate the development of this strategy, several categorizations are discussed: the characteristics of the kinds of systems studied by systems analysts, the many purposes of systems analysis, and the attributes of many systems analysis techniques. The simulation category is examined, together with a breakdown of the spectrum of simulation techniques. Finally, an illustration is given of the way in which the various systems analysis techniques have been used to evolve a greater understanding of supply and inventory policies and systems.
