The US has a big market for pet toys. The operations manager of Squeakers, a pet toy manufacturing company is now seriously thinking of adding a new production line for a special type of pet toys. There are two options of production lines that Squeakers can choose: Advanced production line and Standard production line. The former will cost Squeakers $400, 000; and the latter will only cost $300, 000. The market for the special pet toy is believed to be high at $600,000 at 2/3 chance, and low at $300,000 at 1/3 chance. When the market is high, the advanced production line is capable of handling the high figure of $600,000. However, a standard production line needs some expansion at a cost of $150,000. After the expansion, the sales would be $500,000 due to the lost time during the expansion. If the standard production line is not expanded, the sales would be only $400,000. When the market is low, both production lines are able to satisfy all of the demand. What is the optimal decision?
