Modelling of technological reliability in traffic logistic networks in urban areas

Abstract

The trend of growing parcel numbers with the customer’s desire for shorter delivery times as a result of increasing online trade and economic specialization requires an adjustment of transport systems. The share of transportation costs per postal item depends mainly depends on costs for employees and vehicles, in addition are still the costs of processing in the sorting centers. There are only predictions and experiences for the amount of postal item are available for the tour in advance. The difficult planning leads, in addition to the high cost share and the key feature of a high quality of service to a large relevance to the total transportation process. It is presented an analytical model of the transport process. This includes models to forecast the number of postal items, for capacity-oriented planning of tours and a determination of the current vehicle usage and the volume of transported parcels.
