Method for establishing the working mantime in the production line
First Claim
1. A method of employing a plurality of working means, said method comprising the steps of:
- operating a production line by performing a plurality of production processes according to a first schedule, said production processes being performed by said working means;
determining first working mantimes for said working means for said first schedule, said step of determining said first working mantimes including the step of evaluating work volumes of said production processes performed by said working means;
establishing fatigue recovery mantimes for said working means, said step of establishing said fatigue recovery mantimes including the step of evaluating the fatigue extents of said production processes;
determining a modified schedule for said production line based on said first working mantimes and said fatigue recovery mantimes; and
operating said production line according to said modified schedule, said modified schedule being different than said first schedule, said step of operating said production line according to said modified schedule being performed by said working means, and wherein the steps performed by said working means during said step of operating said production line according to said modified schedule are different than the steps performed by said working means during said step of operating said production line according to said first schedule.

Abstract
Disclosed is a method of establishing working mantime in a production line comprising the steps of: numerically evaluating the work volume for the working means performed in each production process, representing the numeralized work volume as a normal work mantime, then numerically evaluating the fatigue extent of each fatigue task as a fatigue score, and adding the fatigue score to the normal work mantime.
Further, the fatigue score is assigned as a fatigue recovery mantime, and the normal work mantime which includes the fatigue recovery mantime is leveled as uniform, thereby establishing a new production process which includes the leveled fatigue recovery mantime.
