Abstract
An analysis of a number of contemporary bed planning methodologies, either in use or under development, reveals a number of limitations. In particular, the linkage between the optimal size of health facilities and the optimal size of their service areas has often been ignored; in addition, the determinants of utilization of services have often been ignored. An alternative approach to the size–location problem is proposed. Working from health economics–medical sociology concepts, a behavioral model of health services utilization is proposed on the demand side. The interface to the supply side is through a model of the consumer's perception of the total costs facing him in hospital care.
