To assess the rhythm of production is usually performed analysis of production by months, weeks or days. Calculated the planned volumes, performed volumes, shortfalls in production, and the time corresponding to their implementation. Next is a table in which a particular period of time corresponds to a certain rate of release of the goods. The analysis covers the period of time that is required for the precise organization of work.
The overall rhythm (Rd) calculates on the basis of the analysis of production and is determined by the formula:Rd =Ad*100/ S where:Ad is the actual output for the decade;Am - actual production for the month.However, this indicator is quite General because it does not take into account the number of working days in the period, as well as the planned production schedule.
For a more reliable determination of rhythmicity use the ratio of rhythmicity (CR). This value shows the share of output without causing distortion. Use the formula:Cu=AF/AP, where:AF is the actual output for a certain period of time;the AP - the target for the output in the same period of time.
In addition, the coefficient of rhythm and can be calculated according to the formula:Cu=1-Ah/AP where: an execution plan output for a certain period;AP – the planned target for the production for the same period.
In the second case the calculation is based on the planned schedule of release of the goods. To analyze the production and to calculate the coefficient of rhythm can be for any desired period of time: shift, day, week, decade, etc.
Determination of the coefficient of the rhythm is an important stage in operational planning of production, which is a prerequisite for smooth operation of the entire enterprise.
