Abstract—Safe workplace in the subway construction make a major contribution to personnel safety. Safety of the section in the subway construction is often guaranteed or enhanced by work complexity, machine and equipment, accident statistic, accident severity, work environment, and number of workers for these projects. The choice of a sector safety risk in the subway construction involves multiple criteria decision making and ranking of alternatives according to often contrasting performance measures. In this paper, a systematic methodology for selecting a type of sector of subway construction at risk possible to accidents aimed at reducing physical environmental hazards of type of sector in subway construction is presented. The method at first includes a classification of type of sector in the subway construction, then introduces an exhaustive list of 6 factors useful to judge the suitability of selecting a type of sector in the subway construction for comparison purposes. A comparison of relative importance between the rating criteria is then carried out in the framework of the Analytic Hierarchy Process (AHP)decision making approach, based on expert opinion, allowing unambiguous prioritization of the above decision making factors. Limitation and future work of this study are also discussed.

Index Terms—subway construction, risk assessment, multi-criteria decision making, analytical hierarchy process (AHP)
