Emergency material dispatching system and calculating method

Abstract

The invention provides an emergency material dispatching method and system. The system comprises the following structures of: a data input / output module, a data preprocessing module, a material dispatching and operating module, a database operation interface module and a system interface. Aiming at multi rescue point-multi disaster point-multi material dispatching problem, the emergency material dispatching system is used for solving the problem that the vehicle is not full-loaded through comprehensively using multiple algorithms and optimizing multi-material distribution and distribution path so that the model calculating result is more excellent and much faster; and by using the system provided by the invention, locations of the emergency event disaster point and the material distribution point, distance between the emergency event disaster point and the material distribution point, road network as well as other spatial information are provided to the emergency material dispatching; and the emergency material dispatching result can be visually displayed. The emergency material dispatching system provided by the invention has the advantages of stronger practicability and capability of being widely used; and the problems in the prior art are overcome.

Description

field of invention [0001] The invention relates to the field of emergency management, in particular to an emergency material dispatching system and a calculation method. Background technique [0002] It is an important task in emergency management to carry out emergency resource scheduling scientifically and rationally and maximize the value of limited emergency resources. Emergency resource scheduling involves multiple disaster-affected points, multiple rescue points and various emergency materials. The process of transporting materials from the rescue point to the disaster-affected point is a complex multi-objective optimization problem with the goal of the shortest time and the lowest transportation cost. , the research method for this kind of problem is mainly to seek the optimal solution by establishing the emergency material dispatching model and system. [0003] At present, scholars at home and abroad have achieved some results in the research of emergency material d...

Problems solved by technology

Linet Ozdamar (2004) and Claudia Archetti (2008) proposed this type of model, which was solved by constructing a mixed-integer multi-substance network flow model, but there was a problem in the process of model solving, that is, when the optimal vehicle When the number is not an integer, the number of vehicles will be increased to the smallest integer greater than this real number, which means that the vehicle may go to and from the emergency material supply point and different material distribution points many times when it is not fully loaded. Obviously, this is not the same as emergency rescue. The actual scenario does not match; moreover, in the case of many types of emergency materials and supply points, this processing method will cause the calculation results of the overall required number of vehicles and the delivery distance to exceed the actual demand, and the delivery distance and delivery vehicles not optimal

On the other hand, although the emergency resource scheduling model has made great progress in theory and method, there is still a big gap from the wide practical application. In the actual emergency command and decision-making, the application and support of the emergency resource scheduling system are needed.

Most of the existing models are only simulated in numerical calculation software without combining with spatial information, the practicability of the model is not strong, and the calculation speed of the model also affects its wide application
