Research of Models and Methods of construction project information management with 2-tuple Linguistic Information

In recent years, with the development of the times and technological advances, the information management of construction project (IMCP) has been attached more and more importance by the state, government departments and enterprises. The level of R&D in our country has been raised in the field of construction management and the application of information technology in construction project management has been made considerable progress on. In this paper, we investigate the multiple attribute decision making problems for evaluating the construction project information management with 2-tuple linguistic information. We extended the TOPSIS model to solve the evaluation problems of the construction project information management with 2-tuple linguistic information. According to the traditional ideas of TOPSIS, the optimal. altemative(s) is determined by calculating the shortest distance from the 2-tuple linguistic positive ideal solution (TLPIS) and on the other side the farthest distance of the 2-tuple linguistic negative ideal solution (TLNIS). It is based on the concept that the optimal alternative should have the shortest distance from the positive ideal solution and on the other side the farthest distance of the negative ideal solution. Finally, a numerical example for evaluating the construction project information management with 2-tuple linguistic information is used to illustrate the applicability and effectiveness of the proposed model.
