Checking working hours is a very complicated job. The basic idea is to get the total amount of working hours consumed by a batch of parts through the actual production process, and then calculate the working hours consumed by a part. It takes several times to get the average value, and it is necessary to ensure that the real-time work rhythm is normal, and there are no human factors (intentional acceleration or delay) and objective factors (temporary power failure, etc.). ).
It is necessary to eliminate the necessary preparation before work and rest in the middle (going to the toilet, etc.). ), shift change, etc. , record the composition and quantity of different types of work (or auxiliary labor), and record the difference of work efficiency of workers with different proficiency.
Finally, according to the results calculated from the above situation, how many man-hours are needed for a component, including the main types of work, the number of auxiliary workers, the proficiency of workers (several types of work) and so on. I'm just talking about the basic idea. Think about it yourself.
