AI Technical Summary

Technical Problem

Existing technologies make it difficult to scientifically and rationally analyze the duration of construction processes in pumped-storage power station projects, resulting in inaccurate progress control and affecting project quality and safety.

Method used

A method based on semantics and engineering similarity is adopted. By establishing the attribute vector of the extracted engineering process, the Word2vec model is used to build a similar word knowledge base. The Manhattan distance is combined to quantify the attribute similarity, and the comprehensive similarity of the process is calculated. The construction period of the process to be built is then corrected by correcting the construction period of the most similar case.

Benefits of technology

It provides a reliable basis for construction period prediction, improves the accuracy of progress analysis and the level of design intelligence, and enhances the scientific and technological strength and service image of the design unit.

Abstract

The invention provides a pumping and storage project process construction period analysis method based on semantic and project similarity, which comprises the following steps of: determining a plurality of influence factors of a pumping and storage project process construction period, and establishing an attribute vector of the pumping and storage project process construction period according to the plurality of influence factors of the pumping and storage project process construction period; establishing an attribute similarity function of each process attribute in the attribute vector; according to the attribute similarity function, combined with the calculation weight of each process attribute, calculating the comprehensive similarity Si between the to-be-established process Y and each case process Xi in the case process set; and obtaining the most similar case process of the to-be-built process Y through sorting, and correcting the construction period of the most similar case process to obtain the construction period of the to-be-built process Y. The method has the following characteristics that the basis is provided for construction period prediction of the pumping and storage engineering project based on process semantics and engineering project conditions by utilizing experience knowledge of the built project, the intelligent level of pumping and storage engineering progress design is improved, and the scientific and technological strength and the service image of a design unit are improved.
