MODELING UNDER MATLAB OF THE DISCRETE INSTANTANEOUS AVAILABILITY OF A TECHNICAL MEDICAL DEVICE

The study of the environment and constraints of exploitation of the devices and medical equipment allows an analysis of their reliability - maintainability - availability. That can result in the profile from the correspond ing curve of the opérationo - functional calculus availability. This work proposed two digital models, under MatLab, of discrete instantaneous availability starting from the basic model of the continuous instantaneous availability. It is about the discrete i nstantaneous availability without restoring of the timer and the discrete instantaneous availability with restoring of the timer. The two models constitute innovating tools whose service of biomedical maintenance can be useful in a hospital to make decisio ns. Lastly, they are answers to criticisms in the literature on the constant rates of alternation of reliability and maintainability in the basic model
