Abstract

The paper analyzes a new method of calculating additional losses of working time in sequential layout systems, considers the problem of applying modern methods of calculating automated production systems to improve the efficiency of woodworking enterprises. The influence of stochastic factors on the stability of technological operations is analyzed. Additional imposed losses of working time significantly reduce the efficiency of production systems as a whole. In the woodworking industry, technological operations have little stability, so the imposition of loss of working time is particularly pronounced. The actual performance of automated lines is significantly reduced. Improving the productivity of technological lines is performed by developing optimal equipment layout schemes, structural and parametric optimization. An important task is to calculate the component costs of the production process and losses of working time in order to improve production efficiency and manufacture quality products. Existing methods for estimating the imposition of loss of working time are approximate and suitable only for production systems with the same sites. In the case of a large number of consecutive production sites with different nominal productivity, an approximate estimate of the loss of working time is performed using the appropriate calculations used for the two sites. In subsequent calculations, a conditional section is created, which interacts with the next section, the parameters of the new section are calculated and so the calculation is carried out to the end of the production line. For complex production systems, simulation of line operation is performed.
