Abstract:
A method to determine the capacity of a plant over a time window of interest, said time window having a time length P, said method comprising the steps of:(a) assembling said plant's historical production data over a selected time period;(b) creating the cycle entry data set for said time period, said cycle entry data set representinga plant operating time of length L;(c) calculating the capacity (C(i,1)) for each contiguous portion of length P of the cycle entry data set, where ""i"" is an index representing the number of contiguous P length portions of the cycle entry data set of length L;(d) shuffling the elements in the cycle entry data set;(e) calculating the capacities (C(i,j)), j=2, for each contiguous portion of length P of said shuffled cycle entry data set;(f) storing said calculated capacities C(i,2), j=2;(g) repeating steps (d)-(f) a sufficient number of times, incrementing the index j for each iteration; and(h) creating a histogram data set from said stored capacities C(i,j).
