Modeling and analyzing the effects of differentiated urban freight measures − a case study of the food retailing industry

摘要

This paper examines the effects of differentiated urban transport policiesin a real world scenario of food retailers in the city of Berlin. Amicroscopic model is constructed which maps several tactical and operationallogistics decisions. It is an optimization problem for individual firmswhich is solved heuristically considering time-of-day dependent transportcosts. The impacts of urban freight transport policies that differentiatebetween area, time-of-day and vehicle type are discussed and evaluatedby the variations of distribution costs and environmental indicators. Themodel shows that policy measures restricted to a certain area and vehicletypes,can have significant impact on the whole area under examination.;
