Zebra Technologies Corporation (ZTC) manufactures a number of navigation packages for pleasure boats. Their plant in Alabama wants to try a fixed production schedule for the next 6 months. When regular-time production and inventory cannot meet demand, they plan on first using overtime, and if that is insufficient, they will subcontract out in order to meet demand. The forecast for the next 6 months and key production data are provided below. Der What would be the total cost of this plan? If management at ZTC is interested in a chase strategy using a hire/fire option, what is the total cost of this plan? They plan on using a policy where if the need were for 21.2 workers, they would hire 22 workers for that quarter. (Hint: this will impact regular time production and inventory.)
