Analiza sistema za ventilaciju je komleksan proces, koji bazira na proračunu brojnih parametara, koji se odnose na: stanje mreže, provetrenost, stabilnost sistema, gubitke vazduha, klimatske uslove, gasno stanje, ugroženost od požara i opasne prašine. Navedeni problemi se uspešno rešavaju paketom SimVent, ali potpuno razumevanje i korišćenje dobijenih rezultata zahteva angažovanje iskusnog specijaliste iz oblasti ventilacije. Rešenje je nađeno u kreiranju ekspertnog sistema VENTEX, čija je baza znanja formalizacija ekspertskog znanja iz oblasti ventilacije rudnika. U radu je prikazana metodologija projektovanja sistema VENTEX, organizacija baze znanja, struktura ES i korisnički interfejs. Navedeni su i primeri davanja ocena postojećeg stanja ventilacione mreže, kao i preporuka za poboljšanje ventilacije rudnika ukoliko su ocene loše. Za specifikaciju sistema je korišćena objektno-orijentisana analiza, pa OOA model čine: objekti - okviri, slotovi - atributi, metode - demoni i pravila. VENTEX se koristi samostalno ili u kombinaciji sa prethodno razvijenim softverom za simulaciju ventilacije rudnika SimVent. Oba sistema rade u Windows okruženju. Za izradu VENTEX-a je korišćena objektno orijentisana školjka za razvoj ekspertnih sistema KAPPA-PC, zasnovana na konceptu okvira.

Problems relating to mine ventilation system analysis are usually of a very complex nature. They involve the estimation of numerous interdependent parameters pertaining to the network status, ventilation status, ventilation system stability, air current losses, climate conditions, gas state, fire risk and dangerous dust pollution risk. The solution of these problems relies to a great extent on numerical methods. With the development of computer technology these methods were incorporated as numerical routines in software packages, such as the mine ventilation simulation system SimVent. However all potentials of these numerical packages can be fully exploited only by specialists in the field. Besides procedural knowledge encapsulated by numerical routines, the complexity of the subject matter requires a high level of expert knowledge and experience. This knowledge pertains to the heuristics experts use when they apply numerical methods and takes a symbolic form, very often that of rules, being thus declarative in its character. Hence both procedural and declarative knowledge are needed for a successful solution of problems in mine ventilation systems analysis. This paper describes an approach to mine ventilation system analysis which is based on a symbolic upgrading of the numerical SimVent system. The result is VENTEX, a coupled expert system incorporating both procedural and declarative knowledge, that offers the possibility for a more profound exploitation of the available software at an expert level. The paper presents the strategy of mine ventilation system analysis used in the VENTEX system and it formalization using a modification of the object-oriented analysis model as well as the basic architecture of the system and outlines the main features of the implemented system.
