Most books on capital budgeting have been written by economists, or from the point of view of economics. The primary focus of this literature has been the development of models and criteria for making an optimal selection of investment projects. Fred Hanssmann, Professor of Operations Research at the University of Munich, has written a book that takes a much more pragmatic and eclectic point of view. According to Hanssmann, the outcome of an operations research analysis of a capital investment opportunity cannot be a decision about which projects to accept, because "decision-making situations involve conflicting objectives and therefore require the use of multiple criteria" (p. 13). The proper weight to attach to these criteria is a matter of managerial judgment. The role of operations research is to provide better information to management.
