Abstract: There are two common phenomena in a subgrade earthwork construction, one is the queuing problem caused by mechanical resource confliction, and the other is the hysteresis of construction schedule caused by uncertainties. These two phenomena will have a huge impact on the mechanical allocation. Based on the Petri net, queuing theory and uncertainty theory, we firstly establish the whole construction process model under uncertain conditions. Secondly, we solve the mechanical configuration problem according to a designed construction progress. Thirdly, we add some uncertain factors into the mechanical allocation. Finally, through a numerical application, we verify and compare the decisions above.

Keywords: subgrade earthwork construction; mechanical allocation; uncertain conditions.
