EXPERT SYSTEMS USED IN INDUSTRIAL PRODUCTION MANAGEMENT
Dima I.C., Man M. ,Grabara I. , Ciurea V. *
In the conditions of computing the human society, the operational management activities can be improved by using artificial intelligence. Therefore, an expert system is proposed, for the metallurgical industry, for the casting activity for parts necessary in mining industry.
Key words: expert systems, artificial intelligence, interface, search engine, implementing the expert system.
The efficient operation of the integral production systems is based on artificial reasoning, as condition for simulating the human reasoning and supplying the expert's essential role in an actual domain. The expert system represents a major component of artificial intelligence, by means of which the knowledge of some experts in that domain are stored and, by means of a declarative approach, can be then dynamically exploited by an artificial mechanism, simulator of natural rationing triggered at the level of the human brain. The phrase expert system generally evokes the new techniques of management in various activity domains and which are currently assimilated through the notion "contents of a database management".

The expert system for improving the operational management related to the cast items is especially destined to assisting the exploitation and maintenance personnel when diagnosing the complex defects which may occur during the course of this process and for the efficiency of the technical measures that must be taken after the occurrence of those respective disfunctionalities. This system has the advantage of exploiting the memory of the past events and the experience of more experts whom participated at founding the system’s database of know how, without comprising them into an expert system, such knowledge cannot be transmitted to those who ensure the use of the system forward.
The complex mutations that occur in the current industrial context have determined companies to revolutionise their strategies, to search permanent innovation for keeping and/or winning some new market segments. All these occur during aof “explosion" of the IT systems, highlighting the need of integrating all company’s activities by means of the computer. As strategic option in the domain of operational management, computing the activity by using the expert systems represents a pragmatic modality of improvement, which must be explored thenceforth at S.C. UTILAJUL S.A., due to some incontestable advantages such as: performance – the expert systems do not lose their knowledge as time passes by, being capable of continuously working; the possibility of being multiplied – many copies of an expert system may be easily done, while creating new human experts represents a long and expensive process; efficiency – implies low costs compared to performing the expertises by the human specialists; consistency – similar actions are processed and treated in the same manner; objectivity – the system is not accessible as opposed to human experts whom can be subjective; documentation – an expert system may provide a permanent documentation of the decision process; high working speed etc.

SYSTEMY EKSPERCKIE WYKORZYSTYWANE W ZARZADZANIU PRODUKCJA PRZEMYSLOWA
Sztuczna inteligencja moze przyczynic sie do poprawy dzialan zwiazanych z zarzadzaniem operacyjnym w przypadku informatyzacji spoleczenstwa. W zwiazku z powyzszym, w artykule zaproponowano wykorzystanie systemu eksperckiego w przemysle metalurgicznym, szczegolnie w procesach odlewania czesci niezbednych w przemysle kopalnianym.
