Abstract. Substantial reserves for higher operation efficiency in wooden house building businesses exist in improvements of production control system through methods of simulation and optimization. This report presents analysis of key factors of lumber house building processes that influence approaches to production control simulation. The need to factor in interconnection and dependence of lumber and house part production processes is highly difficult for operational control of the production system in question. The optimization mathematical models that we developed will help to solve the tasks of operational scheduling at all stages of wooden house manufacturing, from log cutting to production of finished assembly sets.

In Economic operators Finance theory they have described many models and approaches to assessing the criteria of a firm’s ability to be liable for its debts to the contractors. Despite the fact that the issue of submitting to payment discipline is extremely important nowadays, in practice these approaches and models are used in checking the potential paying capacity either of the contractor or of one’s own firm. The main issue consists in the fact that many rather dogmatic criteria used in the process actually do not lead to accurate results, thus resulting in quite the opposite conclusions due to their abstractedness, as well as to ‘uncertainty’ of the input data. The aim of the paper is to show the ways of calculating one of the key and the most currently used criterion of paying capacity – the absolute liquidity ratio. The paper considers advantages and disadvantages of the already existing approaches, analyzes the results of a negligent approach to payment capacity analysis by the example of calculating the criterion in question. The theoretical background is offered for practical approbation of the viability of the method offered in the paper. The practical part offers a set of successive calculations, shows the algorithm of the calculations according to the method in question.

The textbook provides basic information on modeling and optimization of woodworking processes. The principles of construction and classification of models of objects, methods of mathematical programming, queuing theory, inventory theory, scheduling and network planning are considered in relation to the processes of woodworking.
