Coordination-Controlling And Decision-Making Of Machine Groups For Road Construction Based On Multi-Agent

The thesis is supported by the National 863 Science Plan of China. The project is the researching of intelligent machine groups in construction machinery,No.2001AA422011.My work has researched the coordination-controlling and decision-making of machine groups for road construction based on Multi-Agent. The building and constructing of road, especially the higher grading road , is a project with enormous investment complicated technics and uniting construction of diversiform machines. For assuring the quality of road surface and reducing the cost ,the whole process of construction ,from the purchasing of raw material to mixing,transporting, spreading out and pressing out of construction material, all request to keep the continuous material and to avoid these disadvantages, that is the lower character of real-time and the disadvantage of powerful subjectivity which lied in the traditional construction . For fully exerting the capability of all construction equipments and assuring the building quality, we should establish a perfect systematic structure of constructing machine groups and a intelligent dynamic system of Multi-Agent's coordination-controlling and decision-making system as early as possible.The main work includes:1.Because the constructing machine groups possess the characters of dispersing equipments, fixing roles and flowing work, so we establish a systematic structure which is a layered-distributed tree structure . The structure use for reference the operational mode of company and correspond the whole system running.2.Researching the cooperation and coordination function of Multi-Agent, at the same time , particularly analyzing the coordinating principle of Multi-Agent which was applied in the construction of asphalt concrete road surface , according to the controlling kernel of flowing material and constructing quality; according as the principle ,the course of controlling is actually the course of information streaming, so I respectively introduce the information collecting of different Agents in road constructing .At the same time , I introduce the instruction forming of intelligent controlling Agent and three kinds of fashions for human being-machinecommensalisms, that is Cooperation of machine and human Agent, Architecture of main-machine and assistant-human Agent and Architecture of main-human and assistant-machine Agent, which was applied in different intelligent Agent. Researching the design of Agent controllers for coordination-controlling and decision-making system in road construction; Expatiating the realizing of coordination-controlling and decision-making supporting system in road construction. In my papers, I use the fashion which unite the Expert System and the Decision-making Supporting System (DSS), that is Intelligent Decision-making Supporting System (IDSS). IDSS is applied in intelligent constructing machine groups; Explaining the IDSS program which is writed with Vc ++6.0 language and used in the construction of road surface with asphalt concrete. Simultaneity introducing the flowing chart, interface and the operating of program structure.
