A decision has been made to perform certain repairs on the outlet works of a small dam. For a particular 36-inch gate valve, there are three available Alternatives: A. Leave the valve as it is. B. Repair the valve. C. Replace the valve. If the valve is left as it is, the probability of a failure of valve seats, over the life of the project, is 60%; the probability of failure of the valve stem is 50%; and of failure of the valve body is 40%. If the valve is repaired, the probability of a failure of the seats, over the life of the project is 40%; of failure of the valve stem is 30%; and of failure of the valve body is 20%. If the valve is replaced, the probability of a failure of the seats, over the life of the project, is 30%; of failure of the stem is 20%; and of failure of the body is 10%. The present worth of cost of future repairs and service disruption of failure of the seats is $10,000; the present worth of cost of a failure of the stem is$20,000; the present worth of cost of a failure of the body is $30,000; The cost of repairing the valve now is$10,000; and of replacing it is $20,000.
