Problems solved by technology

When analyzing the mechanized construction combination of earthwork excavation construction, the ideal solution and negative ideal solution of construction cost consumption are the issues that everyone cares about. The TOPSIS method fully considers this aspect. However, the traditional TOPSIS method is difficult to determine the weight of the target attribute , often needs to be given artificially, which has a lot of subjectivity and blindness

Abstract

The invention discloses an entropy weight TOPSIS method based earth excavation machine combination analysis method. The method includes: counting and analyzing different combinations of earth excavation machine construction consumption sample indexes through a mathematic multi-objective decision method, performing sequencing by detecting an Euclidean distance between an analysis object and an optimal solution as well as an inferior solution, and finally determining an optimal earth excavation machine combination scheme. The method combines the entropy weight method and the TOPSIS method to assess an earth excavation machine combination effect, processes the common earth excavation machine consumption data through the entropy theory, determines the weight of all the indexes, applies the weight to the TOPSIS method, and calculates a distance between different kinds of combination scheme data and a positive ideal value as well as a negative ideal value; and the method can analyze the indexes directly from the view of cost consumption, can improve the precision and the practicability of analysis, is simple and easy, can be conveniently used by construction site workers, can remarkably decrease the earthwork construction cost, and can improve the engineering earnings.

Description

technical field [0001] The invention relates to an analysis method for earthwork excavation machinery combination, in particular to an analysis method for earthwork excavation machinery combination based on the entropy weight TOPSIS method, which is applicable to the technical fields of earthwork excavation engineering construction such as water conservancy, municipal administration, construction, road and bridge. Background technique [0002] At present, foreign countries have done a lot of research work in the field of how to rationally allocate earthwork mechanized operation groups and improve the work efficiency of the entire earthwork mechanized operation group. The theory in this field has basically matured. Domestic research on the optimization of mechanized construction organization of earthworks has only started in the last two decades. A large amount of practical experience has been accumulated in mechanized construction of earthworks, and certain results have been ...
