AbstractA computer based, enumerative approach to decision making in a practical environment is described for circumstances where many feasible alternative plans can be generated within given constraints. The method lies between simple techniques for evaluating a few alternative plans and very general techniques such as integer programming, and has advantages over both of these approaches in certain cases. Its main use is as a decision support system, providing management with a range of ranked alternatives. The technique is embodied in a computer program which is used to give an example of how the method may be applied in practice.
