Case Study 1: Project Management – Decision Trees A local toy manufacturer has three different mechanisms that can be installed in a doll that it sells. The different mechanisms have three different setup costs (overheads) and variable costs and, therefore, the profit from the dolls is dependent on the volume of sales. The anticipated payoffs are as follows: Light Demand Moderate Demand Heavy Demand Probability 0.25 0.45 0.3 Wind-up action $325,000 $190,000 $170,000 Pneumatic action $300,000 $420,000 $400,000 Electrical action -$400,000 $240,000 $800,000 What is the ultimate objective in the use of decision trees to product design? How is this objective accomplished? Draw the decision tree. What is the EMV of each decision alternative? Which action should be selected?

an engineer proposes to spend $95,000 on a capital project to upgrade a package delivery system. The project is expected to have labor savings of $20,000 a year plus reduce scrap costs by $5,000 a year. There is expected to be no salvage value at the end of the equipment life, which is anticipated to be 7 years. MARR is 12% What is the present worth of this project?
