Tailwind, Inc., produces high-quality but expensive training shoes for runners. The Tailwindshoe, which sells for $210, contains both gas- and liquid-filled compartments to provide morestability and better protection against knee, foot, and back injuries. Manufacturing the shoesrequires 10 separate tasks. There are 400 minutes available for manufacturing the shoes inthe plant each day. Daily demand is 60.
