Unformatted text preview: . Note that X i E may be either positive or negative; if it’s negative, then we don’t care; if it’s positive, then it would represent a deviation that is beyond acceptable. So, represent X i E by X i E U i U i , where U i ,U i 0 . Note that this encompasses all possible values of X i E (both negative and positive). Then, if we minimize U i we effectively limit the amount that X i E is positive, or the amount by which X i E . Similarly, consider the deviation from the lower limit, i.e., X i F . Note that X i F may be either positive or negative; if it’s posit...
