Application of cyberspace for workshop of meta-synthetic engineering in logistics of large scale construction projects——Real-time dispatching command system for cement and fly-ash in Three Gorges Project

Concrete work with bulk mass such as the dams was the core in the second phase of Three Gorges Project.There were many difficulties such as massive demand of cement and fly-ash,scattered manufacturers in the supply system as well as limited abilities of loading,unloading,storage and transportation. Too many links and the uncertainties of demand and supply could also cause various problems. Especially,the quality of fly-ash,a type of by-product in heat-engine plants,could hardly be unified because generation of electricity always fluctuates according to the power market.The supply of these raw materials was a challenge for the above reason.Based on the principle of cyberspace for workshop of meta-synthetic engineering,real-time dispatching command system for cement and fly-ash in Three Gorges Project was developed,which included the dispatching center,a cyberspace for workshop of meta-synthetic engineering for construction logistics,led by the chief director,for operations of various links:demand, production,transportation,supply,construction management etc.In the information environment with multi-sources and decision support scheduling environment of the command system,the dispatching center would utilize methods like integration of information,integration of theoretical,method and collaboration between man and machine to the conventional scheduling and scheduling in emergencies according to its scheduling routine and rules.This system has been successfully applied in Three Gorges Project,resulting in significant economic and social benefit.It is a typical application case of cyberspace for workshop of metasynthetic Engineering in logistics of large scale construction projects.
