Optimization of regional hazardous waste management systems: an improved formulation

摘要

The planning and design of regional hazardous waste management system (RHWMS) involves selection of treatment and dis- posal facilities, allocation of hazardous wastes and waste residues from generator to the treatment and disposal sites and selection of the transportation routes. An improved formulation based upon multi-objective integer programming approach is presented to arrive at the optimal configuration of RHWMS components. This formulation addresses important practical issues like unique characteristics of the hazardous wastes reflecting on waste-waste and waste-technology compatibility. A utihty function approach is presented to integrate both cost and risk related objectives. An illustrative case example is presented to demonstrate the useful- ness of the improved formulation as a tool which can be used by environmental planning agencies in regional planning for hazar- dous waste management.
