• Abstract:
  Among all the causes of train accidents in the United States, track defects are one of the leading reasons. Basically, the natural processes of wear and fatigue of rail steel can proceed at a rapid pace that results in track defects and short service lives. Therefore, maintenance of rails (such as grinding, ballast cleaning, ditching) is very important for regular railroad operations. One unique feature of these rail maintenance activities is that vehicles may experience variable productivity due to both endogenous and exogenous factors, and thus the actual working duration of a maintenance job is unknown to the operator beforehand and needs to be determined.
