Optimisation of the number of own vehicles for warehouse supply and delivery in case of one warehouse, shuttle services and stochastic capacity needs

The general goal of research is the optimisation of the number of own vehicles performing supply and delivery in case of a logistic service centre that has warehouses, if needs stochastically change. The purpose of this paper is to present the structure of the problem investigated from which the different variants can be derived and to present a simpler model, when the warehouse system consists of only one warehouse and supply and delivery are carried out by shuttle services. Main goal of optimisation is to determine the number of own vehicles by minimizing the total cost function. For the determination of the number of own vehicles it is essential to schedule vehicles, to select the adequate simple and expanded shuttle services.
