This paper introduces the optimization algorithm to improve search rate in urban path routing problems using viral infection and local search in urban environment. This algorithm operates based on two different approaches including wavelet transform and genetic algorithm. The variables proposed by driver such as degree of difficulty and difficulty traffic are of the essence in this technique. W...

In this paper, we are concerned with the problem of location of inspection centers in a multistage manufacturing system. A Genetic algorithm based approach is developed to determine the location of inspection centers resulting in a minimum expected total cost. The total cost includes inspection, manufacturing and scrapping cost at each stage of the manufacturing process. A penalty cost is inclu...

The coaxiality and unbalance are the two important indexes to evaluate assembly quality of an aeroengine. It often needs be tested disassembled repeatedly meet double-objective requirements at same time. Therefore, intelligent method is urgently needed directly predict optimal orientations rotors each stage simultaneously. In this study, optimization for multistage rotor aeroengine proposed bas...
