Stochastic Programming Models 53 For a discrete distribution of R we can convert the above mean–risk model into a linear programming problem. Indeed, let k ¼ 1, . . , K denote scenarios, and let Rik be the realization of the return P of security i in scenario k. The K probabilities of scenarios are p1 , . . , pK , k¼1 pk ¼ 1. Introducing new variables  (representing the mean), and rk , k ¼ 1, . . 0, , r s:t: ð1 À Þ þ  n X K X ) pk rk k¼1 i xi ¼ , i¼1 rk rk , k ¼ 1, . . , K, n X Rik xi , k ¼ 1, .

T À 1 the conditional distribution of t þ 1 given ½1, tŠ ¼ ð1 , . . , t Þ is the same as the conditional distribution of t þ 1 given t . If the process 1 , . . , T is Markovian, the model is simplified considerably. 3) does not depend on 1 , . . 3) depends only on xTÀ2 and TÀ1 . Similarly, at stage t ¼ 2, . . 4) is then a function of xtÀ1 and t , and can be denoted by Qt ðxtÀ1 , t Þ. We shall call then t the information state of the model. In particular, the process 1 , . .

4) is equal to E½Qðx, ފ and the distribution of Qðx, Þ is symmetrical around its mean, then ðQðx, 1 Þ, . . , Qðx, K ÞÞ ¼ E½Qðx, ފ þ ð=2ÞVar½Qðx, ފ: Of course, the mean (expected value) of Qðx, Þ depends on x; in practical applications it would have to be iteratively adjusted during an optimization procedure. 3) is that then the function Ch. 1. 2) can be formulated as a linear programming problem. The above approach to stochastic programming is called robust by some authors. 4) is an example of a mean–risk model.
