Title: Method and equipment for calculating work burden evaluation index and work scheduling method employing it
Inventor: OGATA SATOSHI
IPC: G01M99/00
Filed: 1994-03-03
Abstract: PURPOSE:To allow rescheduling of compulsory work and unrational work schedule by calculating a work burden evaluation index based on an actual work time and a uniform load calculated from the maximum muscular strength ratio and predetermined time thereby determining an index corresponding to the extent of burden for a worker accurately. CONSTITUTION:Twenty pairs of electrodes are set for a worker in order to measure the muscular potential at the time of maximum muscular contraction thus measuring X1 the maximum muscular strength ratio. The measurement is conducted after continuation of work for 5min for each content of work. Subsequently, a uniform load in a standard work providing a same work burden evaluation index is calculated X2 from the maximum muscular strength ratio and a predetermined work time and stored along with the maximum muscular strength ratio. When an actual work time is inputted for each content of work, the uniform load for that work is deleted from the stored data and a work burden evaluation index is calculated X3 from the load and the work time. Accurate index can be calculated for a diversity of works by expressing the extent of work burden in terms of the uniform load in standard work.
