Reverse E-auction has been widely applied to the centralized E-procurement of governments and large enterprise groups recently. In this paper, a multi-item procurement problem with variable quantities is investigated and the organization process of the corresponding reverse E-auction is introduced. The winner determination problem (WDP), which plays an important role in the investigated problem, is...
The aircraft ground service is a key ring to guarantee flight safety and normal operation. In the case of the traveling time of service crew from one aircraft parking place to another to be nonignorable, the scheduling optimization problem of ground service can be described as a vehicle routing problem with time windows of multiply nonidentical vehicles. To solve the problem, we propose a genetic...
In the real world, many practical applications are non-stationary optimization problems. This requires the optimization techniques not only find the global optimal solution but also track the trajectory of the changing global best solution. Dynamic scheduling problems pose great challenges to traditional differential evolutionary algorithms due to the diversity loss and low optimization efficiency...
