Constructional engineering cost management method and system

The invention relates to the technical field of cost management, in particular to a construction engineering cost management method and system, and the method comprises the following steps: collecting the cost data of a construction project, including the material cost, the labor cost, and the equipment use and maintenance cost, calculating the distribution uniformity of the cost data, analyzing the information amount through an entropy calculation method, and carrying out the calculation. And quantifying the multiple cost factors to generate a cost factor entropy value. According to the method, accurate quantification of cost factors and optimization of strategy selection can be realized through comprehensive utilization of entropy calculation and weighting of the decision matrix, the scientificity and practicability of decision are improved, cost management is more targeted and prospective, and through measurement of the distance of the management strategy relative to an ideal solution, the method can be us
