ABSTRACT
A dynamic and stochastic distribution problem with a number of terminals and a fleet of vehicles is analyzed. Customers request the transportation of batches of loads between different origins and destinations. A request can be accepted or rejected; if the request is accepted, a reward is received. Holding costs for vehicles and loads at terminals as well as transportation costs are included in the model. The objective is to determine a policy for accepting transportation requests and for dispatching vehicles that maximizes the expected value (rewards minus costs) of operating the distribution system. A Markov decision process model is developed, optimal policies are characterized, and algorithms that exploit the structure of the problem are developed.

    We consider optimal control problems for stochastic fluid models of the following type: Suppose (Zt) is a continuous-time Markov chain with finite state space. As long as Zt = z, the dynamics of the system at time t are given by a function bz(u(.)), where u is a control we have to choose. A cost...
