1. A method comprising:
determining a baseline lifetime model for a component connected to a machine functional safety system from an equation-based lifetime model, the component part of a system with physical devices, the baseline lifetime model generated from the equation-based lifetime model using initial environmental conditions and usage conditions;
monitoring environmental conditions and usage conditions of the component during usage of the component;
modifying the baseline lifetime model based on the monitored environmental and usage conditions of the component to produce a modified lifetime model for the component by inputting the monitored environmental and usage conditions of the component into one or more equations of the equation-based lifetime model to derive the modified lifetime model of the component being monitored;
tracking a lifetime progress of the component with respect to the modified lifetime model; and
sending an alert in response to lifetime progress of the component reaching a lifetime threshold associated with the modified lifetime model.
