Description

Paper - 12 ppThis paper studies the different behavior of two systems with two-unit cold- standbysystem under the assumption that system 1 works in three different modes Normal, partialfailure and total failure. But system 2 works in two different modes Normal and totalfailure. The failure time and repair time are assumed exponentially distributed. Thetwo systems goes for preventive maintenance randomly (in time). We develop the explicitexpressions for the mean times to systems failure MTSFi (i = 1, 2) and the steady stateavailabilities Ai(1) for two systems by using linear first order differential equations (L.D. E. ), and perform comparisons theoretically and graphically to observe the effect of thepreventive maintenance and failure rates on system performance.
