Abstract

A description is given of a state-of-the-art computerized model which is developed to handle reliability and sparing problems for systems with complex redundancies. The model is used in the daily work when doing different kinds of system reliability analysis. The main applications of SPAREL are discussed. A detailed model description including equipment and maintenance support modeling is given. The mathematical assumptions and the calculation methods are examined. Some program facilities are mentioned, and some examples are presented for a fictitious sample case. SPAREL is a very useful tool since it considers availability, redundancies with complex structures and logistic support as an entity
