Abstract

In an approach, a processor predicts a thermal load caused by a door opening event in at least part of a cargo space of a refrigerated transport vehicle based on, at least, an external ambient condition, environmental factors within the cargo space, and a duration of the door opening event. A processor obtains pre-cooling profile information describing cargo space temperature performance with a pre-cooling operation under conditions corresponding to, at least, the predicted thermal load caused by the door opening event. A processor determines a distribution path for the refrigerated transport vehicle based on the predicted thermal load caused by the door opening event and the obtained pre-cooling profile information, wherein the distribution path is associated with the pre-cooling operation.

Claims (37)

1. A method, the method comprising:

predicting, by one or more processors, a thermal load caused by a door opening event in at least part of a cargo space of a refrigerated transport vehicle based on, at least, an external ambient condition, environmental factors within the cargo space, and a duration of the door opening event;

obtaining, by one or more processors, pre-cooling profile information describing cargo space temperature performance with a pre-cooling operation under conditions corresponding to, at least, the predicted thermal load caused by the door opening event; and

determining, by one or more processors, a distribution path for the refrigerated transport vehicle based on the predicted thermal load caused by the door opening event and the obtained pre-cooling profile information, wherein the distribution path is associated with the pre-cooling operation.

2. The method of claim 1 , wherein the distribution path meets temperature requirements associated with cargo of the cargo space.

3. The method of claim 1 , wherein the pre-cooling operation is further based on thermal capacitance of one or more products located within the cargo space.

4. The method of claim 1 , wherein the external ambient condition includes, at least, temperature, humidity, and wind speed.

5. The method of claim 1 , wherein the pre-cooling profile information is based on, at least, a simulation of temperature changes with the pre-cooling operation under conditions corresponding to, at least the predicted thermal load caused by the door opening event.

6. The method of claim 1 , further comprising:

determining, by one or more processors, to perform the pre-cooling operation based on the pre-cooling profile information; and

causing, by one or more processors, a refrigeration unit, of the refrigerated transport vehicle, to cool the cargo space based on the pre-cooling operation.

7. The method of claim 6 , wherein determining to perform the pre-cooling operation is further based on a predetermined time before occurrence of the door opening event.

8. A computer program product, the computer program product comprising:

one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions comprising:

program instructions to predict a thermal load caused by a door opening event in at least part of a cargo space of a refrigerated transport vehicle based on, at least, an external ambient condition, environmental factors within the cargo space, and a duration of the door opening event;

program instructions to obtain pre-cooling profile information describing cargo space temperature performance with a pre-cooling operation under conditions corresponding to, at least, the predicted thermal load caused by the door opening event; and

program instructions to determine a distribution path for the refrigerated transport vehicle based on the predicted thermal load caused by the door opening event and the obtained pre-cooling profile information, wherein the distribution path is associated with the pre-cooling operation.

9. The computer program product of claim 8 , wherein the distribution path meets temperature requirements associated with cargo of the cargo space.

10. The computer program product of claim 8 , wherein the pre-cooling operation is further based on thermal capacitance of one or more products located within the cargo space.

11. The computer program product of claim 8 , wherein the external ambient condition includes, at least, temperature, humidity, and wind speed.

12. The computer program product of claim 8 , wherein the pre-cooling profile information is based on, at least, a simulation of temperature changes with the pre-cooling operation under conditions corresponding to, at least the predicted thermal load caused by the door opening event.

13. The computer program product of claim 8 , further comprising:

program instructions, stored on the one or more computer readable storage media, to determine to perform the pre-cooling operation based on the pre-cooling profile information; and

program instructions, stored on the one or more computer readable storage media, to cause a refrigeration unit, of the refrigerated transport vehicle, to cool the cargo space based on the pre-cooling operation.

14. The computer program product of claim 13 , wherein the program instructions to determine to perform the pre-cooling operation is further based on a predetermined time before occurrence of the door opening event.

15. A computer system, the computer system comprising:

one or more computer processors, one or more computer readable storage media, and program instructions stored on the computer readable storage media for execution by at least one of the one or more processors, the program instructions comprising:

program instructions to predict a thermal load caused by a door opening event in at least part of a cargo space of a refrigerated transport vehicle based on, at least, an external ambient condition, environmental factors within the cargo space, and a duration of the door opening event;

program instructions to obtain pre-cooling profile information describing cargo space temperature performance with a pre-cooling operation under conditions corresponding to, at least, the predicted thermal load caused by the door opening event; and

program instructions to determine a distribution path for the refrigerated transport vehicle based on the predicted thermal load caused by the door opening event and the obtained pre-cooling profile information, wherein the distribution path is associated with the pre-cooling operation.

16. The computer system of claim 15 , wherein the distribution path meets temperature requirements associated with cargo of the cargo space.

17. The computer system of claim 15 , wherein the pre-cooling operation is further based on thermal capacitance of one or more products located within the cargo space.

18. The computer system of claim 15 , wherein the external ambient condition includes, at least, temperature, humidity, and wind speed.

19. The computer system of claim 15 , wherein the pre-cooling profile information is based on, at least, a simulation of temperature changes with the pre-cooling operation under conditions corresponding to, at least the predicted thermal load caused by the door opening event.

20. The computer system of claim 15 , further comprising:

program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more processors, to determine to perform the pre-cooling operation based on the pre-cooling profile information; and

program instructions, stored on the one or more computer readable storage media for execution by at least one of the one or more processors, to cause a refrigeration unit, of the refrigerated transport vehicle, to cool the cargo space based on the pre-cooling operation.
