2b. A popular heuristic lot sizing method is known as the period order quantity (POQ). This method requires determining the average number of periods spanned by the EOQ and choosing the lot size to equal this xed period supply. Let P be the average number of periods spanned by the EOQ El; \"5 'I'l rounded to the nearest integer. That is, if A = , where n is the planning horizon length, and n- denotes the requirements in period 2', then we compute the EOQ using this value of A, let P = Ei, and round P to the nearest integer to obtain P'. Once we have the integer P', whenever we produce, we always produce the next P' periods' requirements. If, for example, the EOQ equals 139 and A = 43.9, then P = % = 3.17 and P' = 3. Consider the requirements given below fora six-period problem, and assume K = $180, and h = $0.50 per unit per period.
