67-09: The Application of Computer Techniques to the Selection and EvaluationEach requirement for a new cooling tower involves, or should involve, an economic analysis by the buyer to determine which of several offerings represents the "best" buy. Aside from such possible questions as which of several offerings is more conservatively rated or represents higher quality materials (questions which are outside the scope of this paper) there remains the question of which offering represents the lowest total cost as the buyer seas
