PLANNING IN NURSERIES — RESULTS OF AN EMPIRICAL STUDY
The nature of the problems necessarily forces the decision-maker to reduce the degree of complexity by means of simplification. Two main strategies of simplifacation are described. The first one is a strategy of "muddling-through" that considers only incremental deviations from the past behavior. The second concept separates the problem into different decision-areas (input, production, output) that are handled independently so that the simplifacation essentially is achieved by neglecting the interdependencies between these areas. The paper concludes with a discussion of the implications of these concepts for the development of decision aid systems.
