Interplanetary Supply Chain Management The Earthlings opened three settlements on planet Mars so far: Mars Head Quarter (MHQ), Psi, and Omega Arnold Schwarzenegger cannot recall how to activate the alien machine that creates a breathable atmosphere on Mars. Therefore, the United Nations Space Agency (UNSA) is sending out a space transporter every 4 weeks from Earth to Mars. Before each space transporter leaves Earth, MHQ has to decide how much oxygen (and other things) to order. The travel time from Earth to Mars is 6 months (= 26 weeks). Assume 52 weeks in a year. MHQ places each order for all three settlements on Mars together. MHQ also serves as a distribution center on Mars, which means that Psi and Omega receive their oxygen from MHQ (Psi and Omega use the fixed order-quantity model to order from MHQ). The lead times from MHQ to Psi and Omega are two weeks and three weeks, respectively. Each cubic meter (m) oxygen costs 10 space dollars (currency symbol: 0) and carrying costs are 26% of the purchase cost per year. At all extraterrestrial settlements of Earthlings, the required service probability of oxygen is 99.99%, so z= 3.72. Psi's weekly demand is 100 m with a standard deviation of 30 m2. A computer-based system is managing the inventory, and orders to MHQ are placed automatically. The order setup cost is only 10
