sorry for the previous massage ....
shortly i prepare a markov availability model....and i'm a bit
confused, hope someone help me...
a = Lambda[d]/(Lambda[d] + Lambda[in]);
P(0, 0) = 1/(k + (Lambda[in] / Mu[in]) * (k - 1) +
(Lambda[in] / Mu[m]) * (k - 1) +
a* ((1 - a^(n - k)) / (1 - a)) +
(Lambda[in] / Mu[in])* a * ((1 - a^(n -
k)) / (1 - a)) +
(Lambda[in] / Mu[M]) * a * (( 1 - a^(n -
k)) / (1 - a)) +
(Lambda[d] / Mu[D]) * a^(n - k));
> Availability (A) = P(0,0)*(k + (a * (1-a^(n-k))))
> i want to find the optimal Lambda[in] which max. the availability.. is there
