The article proposes to reduce the duration of non-rhythmic flow lines on technologically identical processes by using the resource of «flow-line non-critical» divisions on interdependent works.
In non-rhythmic flow-line construction, there are processes with a reserve of non-used resources with adjacent works («flow-line non-rhythmic» works). As a result of the system study, it is proposed to characterize «flow-line non-critical» works as having an increased period of deployment or convolution of flow lines.
The work volume is redistributed on technologically identical processes, for which interdependent divisions are determined. General new working deadlines are limited by the target function. Additional restrictions determine the limits of change in the term of work on intermediate divisions.
Optimized works are performed in two variants for three and two shifts. This method is more effective in reducing construction and complements the optimization method by reducing the deployment period.
