Abstract

Embodiments of the disclosure include a method for providing a consolidated estimated time of arrival in a scheduled transportation system. The method includes receiving at least one of a scheduled time of arrival, a real-time estimated time of arrival and a predictive estimated time of arrival and assigning a weight to each of the scheduled time of arrival, the real-time estimated time of arrival and the predictive estimated time of arrival. The method also includes calculating a confidence level and the consolidated estimated time of arrival based on the weights and the scheduled time of arrival, the real-time estimated time of arrival and the predictive estimated time of arrival.

Claims

1. A computer system for providing a consolidated estimated time of arrival in a scheduled transportation system, the computer system comprising:

a scheduling device having a processor, the processor configured to perform a method comprising;

receiving a scheduled time of arrival;

calculating the consolidated estimated time of arrival based on the scheduled time of arrival and associating a confidence level with the consolidated estimated time of arrival;

based on receiving a real-time estimated time of arrival re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival and the real-time estimated time of arrival and increasing the confidence level with the consolidated estimated time of arrival; and

based on receiving a predictive estimated time of arrival, re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival, the real-time estimated time of arrival, and the predictive estimated time of arrival and increasing the confidence level with the consolidated estimated time of arrival.

2. The computer system of claim 1, wherein re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival and the real-time estimated time of arrival comprises assigning a first weight to the real-time estimated arrival and a second weight to the scheduled time of arrival.

3. The computer system of claim 2, wherein the first weight and second are calculated based on at least one of a confidence level of the scheduled time of arrival and a confidence level of the real-time estimated time of arrival.

4. The computer system of claim 3, wherein the confidence level of the real-time estimated time of arrival is based on an availability of data and a quality of data.

5. The computer system of claim 1, wherein re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival, the real-time estimated time of arrival, and the predictive estimated time of arrival comprises assigning a first weight to the predictive estimated arrival and a second weight to the real-time estimated time of arrival.

6. The computer system of claim 1, wherein the predictive estimated time of arrival is calculated based at least one of a real time data, a historical data and one or more external variables.

7. The computer system of claim 1, wherein the scheduled time of arrival is based upon a production schedule.

8. The computer system of claim 1, wherein the real-time estimated time of arrival is based upon vehicle information received from a piece of equipment in the scheduled transportation system.

9. A computer program product for providing a consolidated estimated time of arrival in a scheduled transportation system, the computer program product comprising:

a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising;

computer readable program code configured for;

a scheduling device having a processor, the processor configured to perform a method comprising;

receiving a scheduled time of arrival;

calculating the consolidated estimated time of arrival based on the scheduled time of arrival and associating a confidence level with the consolidated estimated time of arrival;

based on receiving a real-time estimated time of arrival re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival and the real-time estimated time of arrival and increasing the confidence level with the consolidated estimated time of arrival; and

based on receiving a predictive estimated time of arrival, re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival, the real-time estimated time of arrival, and the predictive estimated time of arrival and increasing the confidence level with the consolidated estimated time of arrival.

10. The computer program product of claim 9, wherein re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival and the real-time estimated time of arrival comprises assigning a first weight to the real-time estimated arrival and a second weight to the scheduled time of arrival.

11. The computer program product of claim 10, wherein the first weight and second are calculated based on at least one of a confidence level of the scheduled time of arrival and a confidence level of the real-time estimated time of arrival.

12. The computer program product of claim 11, wherein the confidence level of the real-time estimated time of arrival is based on an availability of data and a quality of data.

13. The computer program product of claim 9, wherein re-calculating the consolidated estimated time of arrival based on the scheduled time of arrival, the real-time estimated time of arrival, and the predictive estimated time of arrival comprises assigning a first weight to the predictive estimated arrival and a second weight to the real-time estimated time of arrival.

14. The computer program product of claim 9, wherein the predictive estimated time of arrival is calculated based at least one of a real time data, a historical data and one or more external variables.

15. The computer program product of claim 9, wherein the scheduled time of arrival is based upon a production schedule.

16. The computer program product of claim 9, wherein the real-time estimated time of arrival is based upon vehicle information received from a piece of equipment in the scheduled transportation system.
