AI Technical Summary

Technical Problem

In existing railway engineering construction, the decision-making methods for schedule indicators are difficult to systematically handle multi-attribute, multi-objective, and uncertain information. Simply relying on fuzzy set methods cannot take into account both group benefits and individual preferences, resulting in a lack of scientific rigor and rationality in the decision-making results.

Method used

A project schedule priority evaluation system based on multi-attribute decision-making is adopted. The system acquires multi-source information through the data acquisition module, combines various fuzzy expression forms such as intuitionistic fuzzy sets, hesitant fuzzy sets, and interval value fuzzy sets, and combines the entropy weight method and the analytic hierarchy process to construct a multi-criteria compromise ranking method, generate a comprehensive priority score, and generate a visual report through the result output module.

Benefits of technology

This enabled the scientific and reasonable prioritization of project schedule indicators, improved the objectivity and efficiency of the decision-making process, ensured the scientific and flexible nature of construction management, and enhanced the efficiency and scientific nature of project schedule management.

Abstract

The application relates to the technical field of railway engineering construction management, in particular to a construction period index priority evaluation system based on multi-attribute decision, which comprises a data acquisition module, an attribute weight calculation module, a decision model construction module and a result output module. The system fuses historical case data and expert evaluation, combines various fuzzy expression forms, determines attribute weights through an entropy weight method and an analytic hierarchy process, and generates a construction period index priority ranking based on a double-target optimization principle of maximum group satisfaction and minimum individual regret. The application can effectively integrate qualitative and quantitative information, and improve the scientificity, adaptability and decision efficiency of construction period index evaluation.
