Control Research On Construction Project Multi-process Cross-operation Acceleration Measures

Today, with the continuous progress of science and technology and the continuesdevelopment of society and economy, new changes have been expressed by the modernconstruction project which is the most common and typical type of project, such aslarger investment and scale, longer construction period and so on. However, due to theslow development of construction project management techniques, schedule delay ofthe construction project is a kind of widespread phenomenon in the construction marketnow, which often results in cost overruns and losses of low return rate.For this reason, the study on multi-process cross-operation which the projectmanagers regard as the most common method of acceleration measures will have theimportant theoretical significance and application value. A targeted control model ofmulti-process cross-operation acceleration measures (MCAM) of the constructionproject from the view of contractor site management is built, and it is designed toallocate various resources required for the project acceleration construction rationallyand achieve the duration-cost optimization objective under the premise of ensuring theproject quality, finally providing references for the actual construction projectacceleration measures control.Firstly, on the basis of analyzing the basic model of classic resource-constrainedproject scheduling problem, the function expression of project process implementationmode is described completely which combining with the characteristics of constructionproject resource classification of the six forces theory in technical economics. And thenthe innovative MCAM control theory and control model is established and developedwhich takes the duration-cost optimization as the final objective. Secondly, the elitist strategy and improved techniques are introduced into ant colony algorithm (ACA). Thenthe ACA solving mechanism of MCAM control model is accomplished after combiningwith the forward serial schedule generation scheme. Finally, a feasible project scheduleof an actual project acceleration construction can be achieved by solving this MCAMcontrol model with ACA which has been proved reasonable and efficient by comparingwith other algorithms. The final schedule could provide some valuable solutions for theactual project acceleration construction.
