This paper researched the problem about nodes location and algorithm of continuous uncertain logistics network.For the uncertain demand of logsitics network,it measured each variables by the type of interval,established an interval nodes decision model for logistics network based on gravity method.It considered the practiced and applied characteristics of logistics network,then calibrated the property and interrelation of interval solution to realize the certain transformation of the solving model.It integrated interval operation and genetic algorithm,designed an interval interactive genetic a...
