i made a markov model for a maintenance system with two treshold values and 3 types of maintenance actions. the first state is P(0,0).
i write all my states in the form of P(0,0), then availability(A) function and i want to find the mean time between inspections(let's say x) which max availability (like dA/dx).
i derivated my function in mathematica but i don't know how to find optimal x without giving any numerical values to other constraits (threshold values, mean duration of maintenance activities, mean duration of inspectionand x). i also want to plot dA/dx graph..
is any one able to help me...
