This paper presents a novel navigation sensor for guidance of a flexible tube based on magnetic induction. In many applications, such as pipe inspection and medical intubation, the flexible tube has been utilized for inner surface monitoring and inspection. In particular, for medical intubation that inserts a stomach tube or endoscope, accuracy of locating the flexible tube mainly relies on experienced...
This study improves the original model of vehicle routing problem by adding some strains such as time windows, volume, weight, as parameters into the model. The model is adjusted to an mutilate-goals vehicle scheduling problem based on the mutilate-goals programming, and study on how the time-windows and time-distinction affects the delivering planning. We use GAMS to simulate and solve this problem.
The new approach for vendor selection problem was established under the stochastic environment. After establishing the traditional multi-objective programming model, through minimizing the optimistic value of the net cost of the total order quantity, rejected quantity and late delivered quantity, the multi-objective stochastic constrained integer programming model was established based on the stochastic...
