A SPATIAL CRITERION AS DECISION AID FOR CAPITAL PROJECTS - LOCATING ASEWAGE-TREATMENT PLANT IN HALIFAX, NOVA-SCOTIA

This paper describes a decision tool based on a domain criterion origi nally designed for games against nature. We employ this technique to a nalyse the locational choice of a sewage treatment plant in the city o f Halifax, Nova Scotia, Canada. Based on cost considerations and using the data at hand, we show that only two of the original six locationa l choices remain as serious contenders, both being within less than on e percent of the least-cost decision for a wide range of reasonable pa rameter values. We then discuss the general applicability of the techn ique.
