A MODEL FOR ALLOCATION OF SEWAGE TREATMENT SYSTEMS TO THE NAVAL FLEET
The paper discusses the problem of planning the allocation of sewage treatment systems to the Naval Fleet. It is assumed that the obsolescence or deterioration process of a ship is a semi-Markov process. For the special case of deterministic deterioration, the total discounted cost of revamping a group of ships is determined as a function of the time horizon chosen to do so. This function is graphed for a set of representative cost factors. Finally, the semi-Markov and Markov models are discussed with a view towards a future simulation study.
