In this article, the author discusses some characters on the bamboo slips such as cun(inch), jing(diameter), bo(width), yin(mat), etc. Based on the interpretation of these characters and the position of the related funeral objects, a group of the 6 bamboo slips numbered 2-09, 2-07, 2-10, 2-15, 2-13, 2-02 and another one of the 4 bamboo slips numbered 2-21, 2-23, 2-19, 2-28 are placed in order separately.展开更多

The model aims to dispatch the rescue resources from the regional road networks and to obtain the location of the rescue depots and the numbers of service vehicles assigned for the potential incidents. Due to the computational complexity of the decision model, a scene decomposition algorithm is proposed. The algorithm decomposes the dispatch problem from various kinds of resources to a single resource, and determines the original scene of rescue resources based on the rescue requirements and the resource matrix. Finally, a convenient optimal dispatch scheme is obtained by decomposing each original scene and simplifying the objective function. To illustrate the application of the decision model and the algorithm, a case of the expressway network is studied on areas around Nanjing city in China and the results show that the model used and the algorithm proposed are appropriate.展开更多
