Descrizione articolo

Riassunto:

This monograph gives a systematic overview of the theory of strategies, a new area of enquiry developed by the author over the past two decades. The projects described have applications in air traffic control, verification and validation of simulation models, econometric model building, distributed planning systems for manufacturing, and others.
