Modelling as an Aid to Solid Waste Management Planning: A State-of-the-Art Report

摘要

Mathematical models have often been proposed for use in solid waste management planning. The state of the art has been examined from the viewpoint of the practical guidance which a model can give to the waste disposal officer. A simple conceptual view of the waste management planning system is introduced and used to identify those points in the planning process where models may usefully be applied. Emphasis is given to models for ''strategy evaluation,'' which is the type of model most commonly discussed. The problem is one of piecing together waste arisings and potential facility types and locations for treatment, resource recovery or disposal, to form a waste disposal plan. The various models are classified and discussed according to the assumptions made on important aspects of the real problem. The general conclusion reached is that models can be useful in a practical context, but that their successful use requires care and an understanding by the planner of the strengths and weaknesses of the tool he is using. A pragmatic approach to modelling is suggested, in which simple techniques are used first and more complex models are reserved for detailed study when the situation justifies it.
