摘要:
A scheduling system and method for moving plural objects through a multipath system described as a freight railway scheduling system. The scheduling system utilizes a cost reactive resource scheduler to minimize resource exception while at the same time minimizing the global costs associated with the solution. The achievable movement plan can be used to assist in the control of, or to automatically control, the movement of trains through the system, and is particularly useful in managing the unpredictable movement of local industry trains.

摘要:
A method includes determining candidate schedules for plural vehicles traveling in a transportation network comprising and identifying a gridlock area in the transportation network by simulating travel of the vehicles according to the candidate schedules. The gridlock area includes a geographic subset of the transportation network during a time window having at least a predetermined number of failed candidate schedules that result in a decrease of a throughput parameter. The throughput parameter represents flow of travel of the vehicles in the transportation network. The method also includes determining an alternate schedule that differs from the candidate schedule for one or more of the plural vehicles (e.g., a first vehicle of the plural vehicles) that is traveling through the gridlock area. The alternate schedule dictates travel of the one or more of the plural vehicles (e.g., the first vehicle) without decreasing the throughput parameter of the transportation network.
