An evaluation method and a computing device for influencing factors of substation engineering cost

The invention discloses an influence factor evaluation method and a calculation device of a substation project cost. The method comprises the following steps: according to the construction stage of the substation project, an initial influence factor system of the substation project cost is constructed; the initial influencing factor system is filtered to generate the corresponding simplified influencing factor system; the relationship among the influencing factors in the system of influencing factors are analyzed and simplified, so as to generate the overall influence matrix; the correspondingreachability matrix is formed based on the global shadow matrix, and the influence factors included in the simplified influence factor system are divided into regions according to the reachability matrix; according to the results of regional division, the influence of each factor in the simplified influencing factor system on the substation project cost is evaluated. 本发明公开了种变电站工程造价的影响因素评估方法及计算设备，该方法包括：根据变电站工程的建设阶段，构建变电站工
