In this paper we propose a recursive method in stochastic optimization
problems with compound criteria. By introducing four (Markov, general, primitive
and expanded Markov) types of policy, we establish an equivalence among three
(general, expanded Markov and primitive) policy clatsSes. It is shown that there
exists an optimal policy in general class. Further we apply this result to range, ratio
and variance problems. We derive both forward recursive formula for past-value sets
and backward recursive formula for value functions. The compound criteria is large
for economic decision processes.
