U radu je prikazan model projektovanja složenih kontinualnih sistema korišćenjem teorije pouzdanosti. Ukoliko je interval funkcije cilja unapred definisan, a na osnovu postojećih iskustava za slične sisteme i režime rada može se tačno odrediti, metodom alokacije ukupne pouzdanosti mogu se dobiti zahtevani intervali pouzdanosti za svaki podsistem i analogno za sklop, sve do nivoa mašinskog elementa. Na ovaj način dovodi se u direktnu zavisnost nivo funkcije cilja sa nivoom intervala pouzdanosti svakog od sastavnih elemenata sistema. / A complex continual system design model based on the reliability theory is presented in the paper. If a goal function interval is defined in advance, and can be accurately determined on the basis of experience with similar systems and operation modes, then overall reliability allocation can result in obtaining demanded reliability intervals for each subsystem, each assembly and each mechanical element. In this way the goal function level is brought into direct relation with the reliability interval level of each constituent element of the system.
