Abstract
Harmonization of the flow lines of sawmills and drying shops is a problem in the foundation and operation of enterprises with large-scale mass flow technology. At present, it is aggravated by the fact that the requirement to “cut no more than 8 sections” is practically not met due to a large number of small orders that cannot be grouped and unified.
To synchronize the processes of cutting logs and drying lumber, the “stack accumulator – drying tunnels” system is presented as a multi-channel mass service system with waiting. A special type of open Markov chain of “death and reproduction processes” is used to describe it.
Using the marked graph of system states, a matrix for Markov transitions, Kolmogorov differential equations and expressions for the main operational characteristics of the system are obtained: the probability of full loading of drying tunnels (the efficiency of tunnels); the capacity of the stack accumulator; the waiting time of stacks in the accumulator.
