Worker management system, worker management apparatus and worker management method
First Claim
1. A worker management apparatus used to manage workers performing tasks at a work site divided into a plurality of work areas each in correspondence to specific task contents, comprising:
- a task identification information storage part for storing in memory task identification information correlating each of the work areas in the work site with task contents of tasks performed in the work area;
a worker position identification part for identifying a specific work area where a worker is currently present based upon outputs from a worker detection part installed in each of the work areas, each worker detection part including a receiver that receives electromagnetic waves transmitted from transmitters carried by each of the workers, each of the transmitters being set so as to transmit an electromagnetic wave carrying identification information that can be used to identify a specific worker, the worker position identification part obtaining worker identification information from the worker detection part, detecting the worker detection part that has received the identification information corresponding to a worker undergoing work area detection and identifying the work area in which the worker detection part is installed as the work area where the worker is present;
a current task identification part for identifying the task currently performed by the worker in correspondence to the work area where the worker is located which is identified by the worker position identification part, based upon the task identification information stored at the task identification information storage part;
a task priority level information storage part for storing in memory task priority information;
a new task detection part for detecting that a new task has arisen based upon an electromagnetic wave transmitted from a portable information terminal carried by the worker, the portable information terminal having thereon a sensor for predetermined state detection, the electromagnetic wave indicating a decision value provided by the sensor;
a task reassignment part for engaging the current task identification part to identify current tasks being performed by all the workers when the new task is detected by the new task detection part, assigning task priority levels to all tasks including the current tasks and the new task based upon the task priority level information stored at the task priority level information storage part, and reassigning all the tasks for all the workers starting with a task with a higher priority level, the task reassignment part assigning a task with a higher task priority level as a new task;
an instruction part for issuing instructions for the portable information terminals carried by all the workers to perform tasks reassigned by the task reassignment part;
a worker skill information storage part for storing in memory worker skill information correlating each of the workers with tasks that each of the workers is capable of performing;
a worker extraction part for extracting workers capable of performing the new task based upon the worker skill information stored at the worker skill information storage part; and
a worker identification part for executing worker identification processing by engaging the current task identification part to identify current tasks being performed by the workers extracted by the worker extraction part, ascertaining and comparing priority levels of the current tasks and a priority level of the new task based upon the task priority level information stored at the task priority level information storage part and identifying a worker performing a current task with a priority level lower than the priority level of the new task as a worker to take on the new task.

Abstract
A worker management system, which includes a plant 100 divided into a plurality of work areas each in correspondence to specific task contents, a database 220 having stored therein task identification information correlating each work area 112 with contents of tasks performed therein and worker detection sensors 130 installed in each work area, identifies the specific work area where a worker is currently located based upon outputs from the worker detection means and then identifies the task currently performed by the worker based upon the task identification information. Based upon the current task thus identified, a decision is made as to whether the worker should continue the current task or be assigned a new task and an instruction for task execution is issued to the worker. Therefore the identification of current tasks, the assignment of a new task and the task reassignment are facilitated to improve the work efficiency.
