ジャーナル フリーIn this paper, the theoretical fact that Random fluctuations in feedback control scheme can improve its control performance is verified by using a practical demonstration experiment for a seesaw and cart control equipment. Unstable closed-loop system with a simple proportional control law is stabilized due to the state-dependent fluctuation. Our theoretical expectation on the control performance improvements due to fluctuation are shown from both aspects of numerical simulations and its experimental validation.

ジャーナル フリーGlobal logistic design is becoming a keen interest to provide an essential infrastructure associated with modern societal provision. For examples, we can designate green and/or robust logistics in transportation systems, smart grids in electricity utilization systems, and qualified service in delivery systems, and so on. As a key technology for such deployments, we engaged in practical vehicle routing problem on a basis of the conventional saving method. This paper extends such idea and gives a general framework available for various real-world applications. It can cover not only delivery problems but also two kind of pick-up problems, i.e., straight and drop-by routings. Moreover, multi-depot problem is considered by a hybrid approach with graph algorithm and its solution method is realized in a hierarchical manner. Numerical experiments have been taken place to validate effectiveness of the proposed method.
