1. Decision Rules. A company is choosing a motorized mechanism for a new toy, a dancing ballerina (TippiToes) that is currently under development. Demand is uncertain. but the company is confident that demand will be: Light (25,000 units), Moderate (100,000 units) or Heavy (150,000) units. The payoff table for each mechanism (in $) is given below. Action: Choice of Mechanism Event Gears and Levers Spring Weights and Pulleys Pneumatic Light 25,000 -10,000 -125,000 -300,000 Moderate 400,000 440,000 400,000 300,000 Heavy 650,000 740,000 750,000 700,000 Questions: (1) Apply Maximax, Maximin, Minimax Regret, and EMV rules (assuming that the probability of Light demand is 0.1, Moderate demand is 0.7, and Heavy demand is 0.2) to decide what mechanism should the company choose? (2) What is the expected value of perfect information? (3) Draw a decision tree to solve this problem.
