P(B A) = probability of B, given A. Rules of Addition If A and B are mutually exclusive: P(A B) = P(A) + P(B). If A and B are not mutually exclusive: P(A B) = P(A) + P(B) P(A B). Rules of Multiplication If A and B are independent: P(A B) = P(A) * P(B). If A and B are not independent: P(A B) = P(A) * P(B | A).

Future VALUE S, of a sum of X, invested for n periods, compounded at r% interest S = X[1 + r]n Annuity PRESENT VALUE of an annuity of 1 per annum receivable or payable for n years, commencing in one year, discounted at r% per annum: 1 1.

4 PV = 1 . r [1 r ] n . Perpetuity PRESENT VALUE of 1 per annum, payable or receivable in perpetuity, commencing in one year, discounted at r% per annum: 1. PV =. r LEARNING CURVE. Yx = aXb where: Yx = the cumulative average time per unit to produce X units;. a = the time required to produce the first unit of output;. X = the cumulative number of units;. b = the index of learning. The exponent b is defined as the log of the learning curve improvement rate divided by log 2. INVENTORY MANAGEMENT. Economic Order Quantity 2C o D. EOQ =. Ch where: Co = cost of placing an order Ch = cost of holding one unit in Inventory for one year D = annual demand May 2010 4 Performance Operations
