When conducting a timing, it is important to correctly solve the issue of the number of measurements. The more measurements it is made, the more accurately the average amount of time cost per unit of the product (work) can be determined. But, starting with a certain number, the accuracy of the average time spent will increase slightly, and the further increase in the number of measurements will be practically inappropriate. When determining the number of chronomgrading measurements to study the duration of the elements of the operation, it is necessary to be guided by the following:
Observations are carried out on a special form of the timing map. On its first page, filled on the eve of the observation, a characteristic of the work performed, artist, machine, tools, devices, products, processed breed, production atmosphere at the workplace, indicates the composition of the brigade and the procedure for servicing the workplace. The full name of the operation is also given here (when observing transport operations, the transportation distance is indicated); Description of techniques or components for which the operation is divided; The quantitative composition of the brigade serving the machine, or the number of people performing work.
Chronometing observations are recorded on the second and third pages of the map. The components of which the operation are divided in the technological sequence are indicated in the technological sequence; fixing points of each element are affixed.
At the same time, for the first element, the initial and final points A for subsequent elements only the final point due to the fact that the end point of this element must coincide with the starting fixing point of the subsequent element.
The horizontal line for recording time according to the elements is divided into two parts: the first T current time, the second P is duration. When observing, in a continuous way, the current end time of the elements is indicated in line T, and the line P is filled in the processing of observation.
