What does this n(MAX)j=1 part mean?

I'm not familiar with this notation. If you need more info, let me know. (p.s: Sorry if I'm posting this in the wrong place)

Photo of a printed page showing two formulas: Ep(max) = MAX over j from 1 to n of [ (ts/tw) times the sum over i from j to j + tw/ts - 1 of (Qi - qv)/qv times 100 ], and Ep(min) = MIN over j from 1 to n of a similar bracketed expression.

It means to keep the result for the value of ##j## (between 1 and ##n##) for which the expression in brackets is maximum.
