The selection and planning of the location emergency shelters have a crucial impact on safety residents cities. In this paper, based multivariate open geographic data, Gaussian two-step floating catchment area method, K-means clustering, particle swarm optimization algorithm methods are utilized to carry out spatial accessibility analysis in Deyang City, Sichuan Province, China. study shows tha...

Emergencies cause uncertainty in supply chain environment and risks of disruption. Mitigating such emergency relies on efficient relief material distribution, the distribution logistics system, facility location interacts with allocation clearly. This paper aims to provide a collaborative optimization for temporary centers, objectives minimizing rescue time maximizing demand satisfaction rate. ...

This paper designs a high accuracy spatial location estimation method using ultrasound waves by exploiting the fixed geometry of transmitters. Assuming an equilateral triangle antenna configuration, where three antennas are placed as vertices triangle, problem can be formulated non-convex optimization whose interior is shown to admit Riemannian manifold structure. The investigation newly introd...

In this paper the formulation of the optimal design for wheel location of an omnidirectional mobile robot is proposed as an optimization problem. The empirical comparison of the SQP algorithm and eight different DE variants for this particular optimization problems is presented. The importance of using heuristic approaches in real world optimization problem is analyzed via empirical results.

It is possible to improve vehicle vibration by tuning the parameters of engine mounting system. By optimization of mount characteristics or finding the optimal position of mounts, vibration of the engine and transmitted force from the engine to the chassis can be reduced. This paper examines the optimization of 6-degree-of-freedom engine mounting system based on torque roll axis (TRA) mode deco...
