Multi-factor-based cable line engineering data processing method and system

The invention discloses a multi-factor-based cable line engineering data processing method and system, and aims to solve the problems that a cable line engineering data rectifying method in the prior art is lack of rectifying standards, so that the cost rectifying is inaccurate, and the investment effect is influenced. Comprising the steps of obtaining historical data of a cable line project, extracting influence factors of the historical data, analyzing a conduction mechanism of the influence factors based on system dynamics, and carding the influence factors meeting correlation requirements to form a key index library; and constructing a cable line engineering algorithm based on the key indexes, carrying out cost analogue simulation on the cable line engineering, and setting early warning mechanisms of different grades according to an algorithm result. According to the method, influence factors of cable line engineering data are sorted, key indexes are screened out, the accuracy of the indexes is improved,
