MILP formulations for highway petrol station replenishment in initiative distribution mode

Abstract To investigate highway petrol station replenishment in initiative distribution mode, this paper develops a mixed-integer linear programming (MILP) model with minimal operational costs that includes loading costs, unloading transport and the caused by unpunctual distribution. Based on discrete representation, working day is divided into equal time intervals, truck process decomposed pair of tasks including driving, standby, rest, unloading. Each must execute one task during single interval, currently executing closely related to preceding subsequent tasks. By accounting for predictive time-varying sales at stations, real-time road congestion series constraints, proposed produces optimal dispatch, namely, detailed assignment all trucks each interval. The tested real-world case system comprising eight depot, garage demonstrate its applicability accuracy.
