A new framework of a hierarchical vision-motion planning for a mobile robot under uncertainty is proposed. An optimal plan is generated by twolevel planning: global route selection and local path planning. In global route selection, a sequence of observation points to acquire sufficient information to reach a destination is determined. Both the cost and the uncertainty of vision are considered ...

To increase the efficiency of delivery operations in small package shipping (SPS), numerous optimization models for route and location planning decisions have been proposed. This "operations research view" of defining independent problems has two major shortcomings: First, most models from literature neglect crucial real-world characteristics, thus making them useless for small package shippers...

As the number of adopted alternative fuel vehicles increases, it is crucial for communities (especially those that are susceptible to hazards) make evacuation plans account such refueling needs. During emergencies require preemptive planning, travelers using vulnerable when routes do not provide access stations on their way shelters. In this paper, we formulate and solve a novel seamless route ...
