This article continues the series of the author's works on mechanical systems modeling during process design. It is proposed to use a lattice model describing the product’s mechanical constraints. This model is defined as a partial order on the set of contractible subgraphs. It is shown that many design and technological solutions are described in lattice terms. A set of components that are coordinated relative to each other can be described as an act of a closure operator defined on the set of parts. The images also form a lattice operator which is defined as an algebraic structure.

The article tells about business game properties as a method of active training and test control of knowledge of industrial enterprises staff. A formalized model of realization of a multiuser business game script on the basis of Petri net theory is offered. A formalized description of a multirole business game script design process is considered. The article also considers the structure and principles of creation of programmed software environment for computer multirole business games design.

The summary. Primary goals, methods and models of organizational structure of industrial enterprise management are considered. Formalized methods of organizational management structure synthesis from the point of view of staff recruitment for each work cycle chain of the general production process of the enterprise are described. The article describes the definition of the problem of definition of the structure of a technological communications pseudo-optimum control system, and also methods, models and algorithms of its decision. The article considers principles of multirole business game organization in the form of decomposition, and also tell about the assessment procedure and reassessment of the staff qualification according to the results of a business game.

The article covers the approach to modeling indicators that characterize the need for human resources both at an individual enterprise and a regional labor market (RLM) as a whole, with the use of fuzzy sets. RLM need for human resources is based on criteria values aggregation received for each individual RLM enterprise participating in the study. For this the following were used: a criterion to assess the degree of using human resources on the basis of employment analysis of employees, and a criterion describing human resources motion at an enterprise. Analysis of the received values can be used to forecast future need for human resources.

The work covers a method and its software implementation for the optimum design based on API SolidWorks. Optimization functions are approximated step by step by simplified analytical functions the analysis of which does not demand greater computing expenses. The application is realized as the AddIn DLL-module with COM-interface to SolidWorks. Thus SolidWorks is used by the program as a processor to define current parameters of the model and also as pre- and the postprocessor. To illustrate the work gif-animations are included in the paper.

We consider the extension of an ontological model of knowledge representation in intelligent systems of computer text recognition. For the proposed extension a special term is introduced (GLOTEON): glossary +  thesaurus + ontology. Use of GLOTEON would increase the efficiency of text recognition both on the basis of an ontological model and on the basis of a domain model. The proposed extension would also extend the "ontological" approach to intelligent systems beyond computer linguistics.

The risks are considered as an economic category and their classification is given. The supply chain (SCh) and the measures for its optimization are submitted. The analysis of macro and micro environment of SCh is given as a source of risk rising costs. The relation between the types of risks and factors of their uprising in the macro-and micro-environment is shown.

Problems of management by associations of the organizations in a network are considered: management of object of management without precise borders, necessity of delimitation of a network, management of object without uniform control centre, material and information restrictions of management on communications between the organizations.

The problem of revealing and use of a current functional condition of difficult object for the organization of his maintenance service and repair is considered. Classification of systems of diagnostics from the point of view of the organization of maintenance service and repair on reliability of their forecast is offered. The model of events depending on quality of system of diagnostics is developed and the comparative analysis of expenses for the basic cases (degrees of quality) is lead.

The article considers an application of contours of management in modern network organizations as one of the ways of network management as a whole for achieving the purposes set by a network and the purposes of each separate organization. The article gives a description of management contours, a scheme of interaction of network organizations, results of application of this way of management, and also requirements to network organizations and separate streams between them.

Hot rolling wide-strip mill (h.r. WSM) continue to reserve the leadership in the production of hot rolled strips. Transfer table between roughing and finishing trains the problematic place in the technological line of h.r. WSM where essential uneven cooling along the length of transfer bar. Passive methods heat insulating or reflecting are widely applied at continuous (3/4 continuous) h.r. WSM for cooling reduction of transfer bar don’t eliminate the mentioned phenomenon totally. Last years active methods of influence upon transfer bar temperature at transfer table began to appear in industry: active tunnel furnace Techint (Italy), pseudo-active panel Istok ML JSC (Russia). Heat and energy efficiency of these methods for holding transfer bar temperature are analyzed below.

Dynamic system attainability domain approximate construction problem based on “multi-finish” and model differential equation system vector field approximation methods combination is discussed. The main point of the first method is multiple model differential equation system integration with different controls values. The idea of the second method is preliminary approximation  of model differential equation system’s right side. The purpose of this article is to find out the efficiency of neural network approximation. The research is carried out for 7^th order differential equation system, which describes aircraft center-of-mass motion. Three-layer feed-forward neural network and similar cascaded neural network are analyzed.
