Research On Linear Programming And Algorithm Of Decision Support Of Operations Management

At present, China’s economy has kept rapid development momentum; such trend is torely on highway traffic increases to maintain. In this situation, traffic accidents occurfrequently has become a real issue. By observing we can find that the serious consequences oftraffic accidents have a very direct relationship with the imperfections of the highwaymanagement and the implementation of the rescue operations not in a timely manner. Theunique closed properties of the highway makes the accidents in the system would cause alarge destruction to the upstream traffic and the other side of traffic, and even the surroundingenvironment, significant casualties and property loss is inevitable. Therefore, it is necessary todesign a rescue system that can be used to allocate supplies to the reasonable locations andschedule them in a short time for enhancing the efficiency of traffic incident relief.The problem of the address selection of the emergency services and rescue facilities is avery important issue when the emergency rescue system is build. Put the point in the addressas reasonable as possible, not only able to make emergency rescue work can be commence assoon as possible, emergency supply timely, in the same time,to ensure that the rescue lowestcost, which can largely reduce the cost of the rescue system, thereby enhancing theeffectiveness of the emergency rescue system investment. The location selection model withrescue points was build in the thesis, using the maximum coverage model as the most basicdesign ideas, combined with many factors such as rescue capabilities of the save points andthe demand weights of demand points, in order to make the costs lowest include the operatingand the rescue. The results show that the save points must be put as close as possible by theweight of the larger point of need in whole system, so as to make accidents can be resolved assoon as possible every time, thereby increasing the level of emergency services. In the end ofthe thesis, an instance with data is used to prove the algorithm and the scheme for it, in orderto certify the algorithm can be used in the practical application.In the article, it does not be considered that the factors of transport capacity restrictions.Materials scheduling scheme just consider the scheduling scheme of a single material fromnumber of points of scheduling materials. The scheduling model could achieve the continuousconsumption of the emergency supplies. The most fundamental design concept is to find all of the points which can meet the demand of emergency supplies and have the shortest distancefrom the accident site as the initial location.Compared with the conventional scheduling scheme and the scheme using least points,the scheme in this paper take into account not only the allowable time range and the numberof the points, but also lowing the rescue cost. It is a multi-objective optimization schedulingscheme. In the end of the article, an instance of the model analysis was used to prove thefeasibility of this method in practical applications.
