Abstract

The present invention relates to a human workload management system and method. In order to safely and efficiently control the system, the present invention measures and manages the user'"'"'s workload to manage all actions while the user performs a task, particularly when he drives a car. Also, the present invention manages the user'"'"'s workload when the user interacts with a control system other than to drive.

Claims

1. In a system for managing a user'"'"'s workload, a workload management system comprising:

a user interaction information storage unit for storing and managing information including user condition information, system condition information, external event information, and user secondary task information;

a manager for managing event information provided from the outside of the system and priority task information that is a task performed by the user;

a load manager for managing user'"'"'s resource information and user'"'"'s action information for generating the user'"'"'s load;

a definer for defining a user'"'"'s goal, a detailed action caused by the goal, and a user'"'"'s current action; and

a simulation engine for receiving information from the user interaction information storage unit, the definer, and the load manager, and generating the user'"'"'s load.

2. The workload management system of claim 1, further comprising:

a user workload condition display for displaying the user'"'"'s load degree generated by the simulation engine and information of the user interaction information storage unit;

an information sensor for collecting the user'"'"'s condition information, system condition information, and external environment condition information; and

a system controller for controlling the user interaction information storage unit, the manager, the definer, the load manager, the simulation engine, the user load condition display, and the information sensor through the user interaction information manager.

3. The workload management system of claim 2, wherein

the manager includes:

an external event information manager for managing event information that is generated from the outside of the system;

a user task information manager for managing information on a secondary task performed by the user, the secondary task being performed other than the priority task; and

a system interaction information manager for managing interaction information of the system.

4. The workload management system of claim 2, wherein

the definer includes:

a user goal definer for defining and storing information on the user'"'"'s goal managed and generated by the manager;

a detailed action definer for defining a detailed action to be performed according to the user'"'"'s goal; and

a current action definer for defining an action that is currently performed from among detailed action information divided by the simulation engine, and storing the same.

5. The workload management system of claim 2, wherein

the load manager includes:

a user resource manager for checking and managing the capacity used for the user'"'"'s resource information, the resource information being divided into a first resource and a second resource; and

a user action definer for defining a goal performed by the user and the user'"'"'s detailed action to be performed so as to fulfill the goal, and storing and managing a goal and a detailed action that are changed or added according to an input by the user.

6. The workload management system of claim 1, wherein

the simulation engine includes:

an event information collector for receiving external event information from among information collected by the information sensor;

a task collector for receiving the user'"'"'s secondary task information from among the information collected by the information sensor;

a goal inferring unit for inferring the user'"'"'s goal from the received external event information and secondary task information;

an action divider for dividing the user'"'"'s goal inferred by the goal inferring unit into detailed actions; and

an action checker for selecting the action to be currently performed based on information on the detailed actions divided by the action divider.

7. The workload management system of claim 6, further comprising:

a timer driver for increasing a time that is used as a reference for storing information on the user'"'"'s action.

8. In a method for managing a user'"'"'s workload, a workload managing method comprising:

inferring a user goal from external event information and the user'"'"'s secondary task information from among predetermined information collected through an information collecting means, the predetermined information including user condition information, system condition information, external event information, and user secondary task information;

selecting an action to be currently performed from the inferred user goal; and

determining whether the selected action is a scheduled action, and managing the user'"'"'s workload by performing the action when it is found to be a scheduled action.

9. The workload managing method of claim 8, wherein

the selecting of an action includes:

classifying a plurality of detailed actions from the inferred user goal; and

selecting the action to be currently performed from among the classified detailed actions.

10. The workload managing method of claim 9, wherein

the classifying of detailed actions includes:

determining whether there is an emergency action having emergency priority information;

controlling the actions other than the emergency action to be stopped, and updating condition information of all actions that are currently performed and an action instance;

updating a resource utilization table according to stopping of the action;

adding information on an emergency action to a detailed action definer based on the emergency priority information, and eliminating action stopped action information in the current action definer;

determining whether emergency actions remain, and scheduling performance of the emergency action by referring to the resource utilization table for the remaining emergency actions; and

updating condition information of the scheduled emergency action, and updating the resource utilization table for the emergency action.

11. The workload managing method of claim 10, further comprising,

when there is no emergency action having the emergency priority information:

determining whether all actions other than the emergency action are considered;

scheduling performance on one of the remaining actions when all the actions are not considered; and

determining whether there is an emergency action, and when there is no emergency action, updating condition information for one of the actions, and updating the resource utilization table.

12. The workload managing method of claim 8, wherein

the performing of an action includes:

storing start time information when the action is performed and the action information;

updating condition information before the action is started and condition information after the action is started in the information storage unit when the action is performed; and

deleting the action information from the current action definer.

13. The workload managing method of claim 8, wherein the method includes,

when the selected action is not a scheduled action:

determining whether the selected action is an action that is currently performed;

adding action duration time information to the action started time information when it is an action that is currently performed;

displaying condition information of the action as finished, and updating a resource utilization table; and

updating condition information after the action is finished in an information storage unit.

14. The workload managing method of claim 13, further comprising,

after the updating in the information storage unit:

determining whether the action is the last action;

determining whether the action is repeated in the goal when it is the last action;

inserting information on the goal when it is a repeated action in the goal, and deleting information on the goal when it is not a repeated action.

15. The workload managing method of claim 8, wherein

the inferring of a user goal includes:

selecting one of a plurality of goals stored in a system, and determining whether the goal satisfies pre-conditions;

performing the goal, and selecting one of a plurality of methods for fulfilling the goal when the goal satisfies pre-conditions;

dividing the selected method into a lower goal and a basic action;

adding pre-effects for the goal as the first action of the goal or pre-effects of the first lower actions;

turning over the priority of the goal to the lower goals, and adding the goal for the lower goals as a parent goal; and

turning over the goal to the basic action as a parent goal.
