Abstract

A method, system, and computer program product for occupant-based elevator actions are provided. The method identifies a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects. A set of initial priority statuses are generated for the set of subjects. Based on the set of identities and the set of initial priority statuses, an elevator dispatch solution is determined. The method updates at least a portion of the initial priority statuses to generate a set of subsequent priority statuses in response to a subset of subjects entering at least one elevator. The method determines an isolation response for a first subject of the subset of subjects and modifies the elevator dispatch solution based on the isolation response to generate an isolation dispatch solution. The at least one elevator executes the isolation dispatch solution.

First claim

What is claimed is:

1. A computer-implemented method, comprising:
identifying a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects;
generating a set of initial priority statuses for the set of subjects, each initial priority status generated based on an identity for a subject of the set of subjects;
based on the set of identities and the set of initial priority statuses, determining an elevator dispatch solution for one or more elevators of the set of elevators;
in response to a subset of subjects entering an elevator, updating at least a portion of the initial priority statuses to generate a set of subsequent priority statuses;
determining that at least one identity generated for the subset of subjects is associated with a preset response code;
in response to the determining, adjusting interior settings of the elevator based on the preset response code;
determining an isolation response for a first subject of the subset of subjects;
modifying the elevator dispatch solution based on at least a portion of the set of subsequent priority statuses and the isolation response to generate an isolation dispatch solution; and
causing the elevator to execute the isolation dispatch solution.

2. The method of claim 1 , wherein the set of identities is generated based on first identification information obtained by one or more facility sensors.

3. The method of claim 2 , further comprising:
in response to the subset of subjects entering the elevator, modifying a subset of identities based on second identification information obtained by one or more elevator sensors, the subset of identities corresponding to the subset of subjects entering the elevator.

4. The method of claim 1 , wherein the isolation response is determined based on an identity of the first subject.

5. The method of claim 1 , wherein the isolation response is determined based on an isolation event associated with the first subject.

6. The method of claim 1 , wherein executing the isolation dispatch solution isolates the first subject from one or more subjects of the subset of subjects that entered the elevator.

7. The method of claim 1 , wherein executing the isolation dispatch solution locks one or more manual interface controls of the elevator.

8. A system, comprising:
one or more processors; and
a computer-readable storage medium, coupled to the one or more processors, storing program instructions that, when executed by the one or more processors, cause the one or more processors to perform operations comprising:
identifying a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects;
generating a set of initial priority statuses for the set of subjects, each initial priority status generated based on an identity for a subject of the set of subjects;
based on the set of identities and the set of initial priority statuses, determining an elevator dispatch solution for one or more elevators of the set of elevators;
in response to a subset of subjects entering an elevator, updating at least a portion of the initial priority statuses to generate a set of subsequent priority statuses;
determining that at least one identity generated for the subset of subjects is associated with a preset response code;
in response to the subset of subjects having entered the elevator, adjusting interior settings of the elevator based on the preset response code;
determining an isolation response for a first subject of the subset of subjects;
modifying the elevator dispatch solution based on at least a portion of the set of subsequent priority statuses and the isolation response to generate an isolation dispatch solution; and
causing the at least one elevator to execute the isolation dispatch solution.

9. The system of claim 8 , wherein the set of identities is generated based on first identification information obtained by one or more facility sensors.

10. The system of claim 9 , wherein the operations further comprise:
in response to the subset of subjects entering the elevator, modifying a subset of identities based on second identification information obtained by one or more elevator sensors, the subset of identities corresponding to the subset of subjects entering the elevator.

11. The system of claim 8 , wherein the isolation response is determined based on an identity of the first subject.

12. The system of claim 8 , wherein the isolation response is determined based on an isolation event associated with the first subject.

13. The system of claim 8 , wherein executing the isolation dispatch solution isolates the first subject from one or more subjects of the subset of subjects that entered the elevator.

14. The system of claim 8 , wherein executing the isolation dispatch solution locks one or more manual interface controls of the elevator.

15. A computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions being executable by one or more processors to cause the one or more processors to perform operations comprising:
identifying a set of subjects approaching a set of elevators to generate a set of identities for the set of subjects;
generating a set of initial priority statuses for the set of subjects, each initial priority status generated based on an identity for a subject of the set of subjects;
based on the set of identities and the set of initial priority statuses, determining an elevator dispatch solution for one or more elevators of the set of elevators;
in response to a subset of subjects entering an elevator, updating at least a portion of the initial priority statuses to generate a set of subsequent priority statuses;
determining that at least one identity generated for the subset of subjects is associated with a preset response code;
in response to the determining, adjusting interior settings of the elevator based on the preset response code;
determining an isolation response for a first subject of the subset of subjects;
modifying the elevator dispatch solution based on at least a portion of the set of subsequent priority statuses and the isolation response to generate an isolation dispatch solution; and
causing the at least one elevator to execute the isolation dispatch solution.

16. The computer program product of claim 15 , wherein the set of identities is generated based on first identification information obtained by one or more facility sensors and wherein the operations further comprise:
in response to the subset of subjects entering the elevator, modifying a subset of identities based on second identification information obtained by one or more elevator sensors, the subset of identities corresponding to the subset of subjects entering the elevator.

17. The computer program product of claim 15 , wherein the isolation response is determined based on an identity of the first subject.

18. The computer program product of claim 15 , wherein the isolation response is determined based on an isolation event associated with the first subject.

19. The computer program product of claim 15 , wherein executing the isolation dispatch solution locks one or more manual interface controls of the elevator.

20. The method of claim 1 , wherein generating the initial priority statuses comprises generating a priority record for a subject from the set of subjects, the priority record comprising an initial priority score and a response code associated with an identi
