Research On Method Of Construction Machinery Group Optimal Configuration And Dynamic Dispatch

Along with the fast development of our national economy, the quantity of capital construction projects has been doubled as well as the improvement of its quality. Large number and a great variety of construction machinery are used in these projects, and the investment in construction machinery group is quite high. Optimal configuration and dispatch of construction machinery group becoming the key factor that influencing the process, quality and economy of these projects. Construction machinery group optimal and dispatch mainly include the proper selection of construction machinery, appropriate configuration of main construction resource and assistant construction resource, and construction machinery dynamic dispatch during construction process. In the construction practices, people are aware of the importance of construction machinery optimal configuration and dynamic dispatch, and much work has been done of this field. Because the construction machinery group configuration and dynamic dispatch are concerned with multi influencing factors, existing research findings are usually complex, and narrowed its application in practical construction process. The aim of this dissertation is to find out key influencing factors and their correlation in construction machinery group configuration and dynamic dispatch, and to construct machinery group optimal configuration and dynamic dispatch which is feasible for practical application. Construction machinery group optimal configuration and dynamic dispatch are two individual systems and have interrelation at the same time. This dissertation plans to construct machinery group optimal configuration and dynamic dispatch method, and program optimal configuration software. In this paper, I have done research on following aspects: ⑴On the basis of analysis of existing research methods of construction machinery group, I chose Construction Machinery Group Optimal Configuration and Dynamic Dispatch as the topic of this dissertation. ⑵Through study, probed expert system and dynamic planning that are part of the theoretical basis for construction machinery group optimal configuration and dynamic dispatch. ⑶Through research on process methods of construction machinery group, constructed the general structure of construction machinery group optimal configuration and dynamic dispatch. ⑷Through analysis of construction machinery group configuration, constructed the system model of machinery group configuration. ⑸On the basis of theoretical research, with the combination of expert system and converted expenses method, programmed application software of Construction Machinery Group Optimal Configuration. ⑹Using the software, made simulation experiment of construction machinery group configuration, acquired a series of data, which is essential for consummating the software. This dissertation has made such improvement: ⑴Constructed Construction Machinery Group Optimal Configuration Model. ⑵Constructed Machinery Group Dynamic Dispatch Model. ⑶On the basis of theoretical research, with the combination of expert system and converted expenses method, programmed application software of Construction Machinery Group Optimal Configuration.
