MODEL PENTRU EVALUAREA IMPACTULUI FIABILITĂŢII ASUPRA ANALIZEI COSTULUI PE DURATA DE VIAŢĂ APLICABIL SISTEMELOR TEHNICE COMPLEXE (Rezumat) Lucrarea prezintă aparatul matematic al modelului cu rata distribuţiei defecţiunilor de tip Weibull precum şi un studiu de caz prin care acest model a fost aplicat unui sistem complex de tip vehicul specializat pe roţi. Modelul cu rata distribuţiei defecţiunilor de tip Weibull se poate utiliza pentru evaluarea obţinerii unei operativităţi ridicate pentru sistemele complexe de tip vehicul specializat pe roţi. Astfel
Bul. Inst. Polit. Iaşi, t. LVIII (LXII), f. 3, 2012 33 pentru a se asigura eficienţa operaţională a sistemelor tehnice acest model poate contribui la rezolvarea unui număr ridicat de cerinţe cu resurse limitate.
