Development of a Multi-agent Collision Resolution System at the Supply of Spare Parts and Components to the Production Equipment of Industrial Enterprises

The approach to the creation of computer facilities for the automation of the technical maintenance of production equipment (TMPE) at industrial enterprises (IE) is outlined. Meaningful and formal statement of the problem of forming solutions for identifying and eliminating collisions that arise when delivering spare parts and components for TMPE are presented. The method of formation of coordinating decisions on maintenance with spare parts and accessories for carrying out TMPE at IE is described. The organization of intellectual support of formation of coordinating decisions by recognition of potential collision in the TMPE process is offered. This procedure involves checking the real existence of the collision and issuing a coordinating decision. In this case, the decision is formed in the event of a disagreement between the need for spare parts and components for the TMPE maintenance, with their availability in the PP warehouse. The ways of software implementation of this method in the environment of multi-agent system are considered. In particular, the description of the multi-agent system developed during the prototype research is given. The prototype is implemented using CORBA technology, in accordance with DSTU ISO/ EC 2382-15:2005. The calculation of the efficiency of the application of the developed computer tools in production is shown. To assess the quality of the system, a sliding control method based on leave-on-out cross-validation (LOOCV) is applied

Development of the Temporal Knowledge Representation Model for Computer Support of Consumer Goodd Production Processes at Multi-nomenclature Machine-building Enterprise

The object of research is the processes associated with the organization of the production of consumer goods (CG) at the multi-nomenclature machine-building enterprise (MME). These processes are considered in the aspect of automating the production of consumer goods by creating a special model of knowledge about the current state of production processes. One of the most problematic issues is the complex automation of combined processes for the production of basic products and CGs at MMEs. The solution of this question required the improvement of the formal apparatus for modeling time dependencies. In the course of the research, discrete mathematics methods, in particular set theory and mathematical logic, are used, as well as tools that are known in knowledge engineering, in particular production systems.A temporal model of knowledge and technology is combined with the knowledge base of the decision support system. The peculiarity of this model is the possibility of adequate reflection of asynchrony and parallelism, which is inherent in the processes of CGs production at MMEs. The overall effect of the implementation of the developed model of knowledge will be achieved by reducing the incidence of disruptions in the production program, preserving the professional knowledge of experienced MME specialists in the production of consumer goods. In addition, the use of the temporal knowledge model as part of the intellectual core of the decision support system will ensure the reduction of the MME costs in the organization of production of consumer goods
