INTEGRATED ROUTING AND SCHEDULING IN HAZARDOUS MATERIALS TRANSPORTATION

Recognition of time-varying patterns of accident rates and exposure pa rameters can be used to improve routing and scheduling decisions for h azardous materials shipments. An integrated routing/scheduling approac h can be used to reduce overall risk, and find preferred solutions in a multiobjective context. We describe a method for performing an integ rated routing/scheduling analysis, and illustrate its use in a case st udy. We also construct estimates of the ''value of information'' for i ncorporation of this time-dependent data.
