The paper discusses principles of establishing the duration of manufacturing cycle for a batch of parts using the computational method. A classification of manufacturing cycle components appropriate for this method is presented, as developed based on the classifications proposed in literature on the subject. The paper gives characteristics of the cycle components, for which the time periods are established. Formulas used to determine the length of manufacturing cycle are presented. Individual types of formulas are applicable depending on the availability of data and demand for a specific degree of result accuracy. Formulas are presented for the engineering period of a cycle taking into consideration serial, parallel and mixed serial-parallel production for a batch of parts.
