Food products are among the most frequently delivered items to retail shops in city centres and also need special attention owing to their perishable nature and quality requirements. The main objective of this study was to map out the segments of food distribution systems and determine the constraints and possibilities in developing a co-ordinated and optimised food distribution system in and around Uppsala city, to promote efficiency and environmental sustainability. The study was conducted by arranging a series of seminars, carrying out field measurements, optimisation analysis and emission estimation. Data on eight companies that distribute food in and around Uppsala city, distribute were gathered and analysed. Different tools were used successfully i.e. Global Positioning System (GPS) for field measurement, RouteLogiX for route optimisation analysis and MODTRANS (a Matlab based package) for emission estimation. Optimising the individual routes reduced travel distance by 39% and time by 40% while total optimisation reduced the number of routes by 58%, the number of vehicles by 42%, and the total distance by 39%. Consequently, optimisation could reduce emissions generated by vehicles by 48%. 相似文献
