The establishment of a comprehensive evaluation model of productivity construction projects in the Sichuan Basin

Abstract

In the process of natural gas productivity construction in the Sichuan basin, in order to carry out the technical and economic feasibility demonstrations based on the productivity of the construction project, it is necessary to establish an integrated productivity and economic risk evaluation model based on the productivity prediction of natural gas and considering the impacts of economic benefits and various risks. Based on the economic evaluation of productivity construction projects, this paper analysed the risk evaluation standards of productivity construction projects in the Sichuan basin and quantified risk indicators at all levels, then used 0-1 regularization method and Monte-Carlo technique to establish the risk evaluation model, and finally achieved projects scheme scheduling and multi-scenario, multi-scheme target optimal combination by synthesizing the economic evaluation model, risk evaluation model, and comprehensive evaluation model established by AHP method of productivity construction projects.
