STATISTICAL ANALYSIS OF A TWO-UNT COLD STANDBY SYSTEM WITH TWO-TYPES OF FAILURE AND PREVENTIVE MAINTENANCE

Résumé

This study presents the statistical analysis of two dissimilar parallel units in cold standby. Each unit works in two different types of failure as failure of type I and failure of type II. System fails when both units fail totally. The system goes for preventive maintenance at random epochs. The failure and repair time and preventive maintenance time are assumed to have different arbitrary distribution .
