Abstract:
A method to determine the capacity of a plant over a time window of interest, the time window having a time length P, having the steps of:
(a) gathering the plant's historical production data over a selected time period of length L and calculating the cycle entries for that data set;
(b) calculating capacity C(i,1) for each contiguous portion p(i,1) of length p of the cycle entries from the previous step;
(c) storing that calculated capacities C(i,1);
(d) randomly shuffling the cycle entries;
(e) calculating the capacity C(i,2) for each contiguous portion p(i,2) of the shuffled cycle entries;
(f) storing the calculated capacities C(i,2); and
(g) repeating steps (e)-(f) for a sufficient number of iterations, and then creating a histogram of the calculated capacities C(i,j).
