This paper studies the problem of high-speed train operation with special attention to minimizing the energy consumption. The performance characteristics of a high-speed train, including traction characteristic and regenerative braking, and the railway geographical conditions consisting of slope, curve, and tunnel parameters, are fully considered in the dynamic model in order to make it more effective...
This paper investigates the vehicle routing problem (VRP) under multi-objective constraints. More specifically, we consider the distance, fixed cost, time, together with risk simultaneously. To get a quicker and more accurate solution, several improvements are proposed in applying GA for optimization search. Practical test confirms the effectiveness of the proposed method.
The paper presents a novel structure for operator of vacuum load-disconnection switch. The fundamental principles and features of this new design are discussed in detail. This is a multiple objective optimization problem, and generic algorithm method is used for the design. It is shown that generic algorithm based optimal design for operator of vacuum load-disconnection switch is feasible and effective,...
