The Extended Control Language of MPSX/370 and possible applications

The application of mathematical programming to large-scale practical problems has been hampered by the absence of reliable tools other than linear programming (with the possible exception of such techniques as simulation, project management, econometric forecasting, etc.). There exists a wealth of know-how, algorithms, and heuristics, but their realization in practice has been lagging, being largely limited to small-scale or highly specialized problems.
