Abstract

In view of the low efficiency of inspection and pricing caused by frequent design changes and cross-disciplinary information fragmentation in long and long trunk railway projects such as Ganqing section of Lanzhou-Xinjiang high-speed railway, Aiming at the demand priority decision-making problem of BIM inspection and pricing system in railway engineering, by constructing KANO-TOPSIS dual-model coupling framework, based on the survey results of 156 questionnaires and the scoring results of 15 experts, firstly, KANO classification results are corrected by role weight coefficient to identify necessary, expected and attractive demands; Then, TOPSIS model is used to quantify and sort 22 high-value demands in KANO classification results from five dimensions, such as technical difficulty and business value; Based on the results of the dual models, a four-level R&D strategy matrix is constructed, and the phased implementation path and risk avoidance measures are put forward. The empirical results show that the framework can effectively reduce the risk of mismatch of R&D resources, provide a reusable paradigm for the demand analysis of intelligent railway engineering systems, and promote the transformation of BIM from visual tools to pricing core engines.
