Abstract

The author shows a method of using the balance criterion in elaborating operations by establishing a relationship between the sum of the time needed for motions or actions necessary for the processing of the product, and motions or actions necessary for the preparation and postponement of processing. As this ratio is approximately 1:1, it is possible to establish the labour rhythm, normal fatigue of the worker, as well as other criteria for evaluation. Therefore, the balance criterion could be considered as a more suitable and more objective criterion in determining criteria of elaborating operations. The methodology of elaboration is also presented and the results obtained on two operations, 1.05:1 and 0.96:1, justify the validity of the use of this criterion.
