title = "A bi-objective railroad track inspection planning problem",
abstract = "Track inspection, specifically automated ultrasonic inspections of railroad tracks, is one of the most important safety operations that State Department of Transportation and railroad companies need to plan. This study analyzes a track inspection scheduling problem (TISP) considering the practical constraints and objectives of track inspections. TISP is a bi-objective binary optimization problem, where the total time to complete the predetermined number of inspections on a given set of railroad tracks is minimized and the total weighted importance of the inspections is maximized. We explicitly consider the track inspection times, the travel times between tracks, and the time required between two consecutive inspections of the same track. Two greedy algorithms are proposed and used to approximate a set of Pareto efficient inspection schedules.",
