But how profitable it could be under different circumstances In other words to Accepted July 11 2019 Available online which factors its influence depends on what are its benefits versus its costs The present July 11 2019 research aimed to give a relatively comprehensive answer to these questions using a Keywords mathematical model of the pickup and delivery system with transfers. According to the model Transfers results under different situations many factors such as modeling assumptions system goals Pickup and delivery systems transportation network scheme vehicle fleet in terms of capacity cost rate and time window Mixed integer programming of activity and requests in terms of the length direct distance between the pickup and delivery points time windows and the volume to vehicle capacity ratio affect the transfers benefits. As the small-scale numerical results indicate we have an average of reduction in the trip cost under normal conditions which increases with the heterogeneity of vehicles shorter time windows and an increase in the length of the request.
