The Optimization Of Construction Machinery Scheme Of Cast-in-situ Concrete Based On Improved Weight Coefficient Method

The construction machinery of the cast in place concrete is the main body of the construction engineering concrete construction.The different mechanical combination schemes have different influences on the safety of engineering quality,the progress of the project,the construction cost and so on.Based on the characteristics of the cast in place concrete construction machinery and the theory of multi index comprehensive evaluation,this paper puts forward a comprehensive evaluation model for the construction machinery scheme of the cast in place concrete by the research and improvement of the " scatter degree " comprehensive evaluation method.The evaluation model includes the evaluation index system,the acquisition and the pretreatment of the evaluation index system,the determination of the weight coefficient,the selection of the method of assembly.Through the comparison between the results and the new and old methods,the advantages and the feasibility of the method are described,and the value of the method is applied to the practical engineering.On the basis of theoretical research,combined with the evaluation theory and software technology,the paper develops a set of software which has the function of optimizing the construction machinery scheme.The software has not only the construction machinery scheme optimization function,but also the concrete engineering construction project construction and other practical functions,such as mechanical calculation,making it become a function of a variety of construction engineering concrete construction software.
