An airport needs a modern material handling system for facilitating access to and from a busy maintenance hanger. A second-hand system will cost $75 comma 00075,000. A new system with improved technology can decrease labor hours by 2020% compared to the used system. The new system will cost $150 comma 000150,000 to purchase and install. Both systems have a useful life of five years. The market value of the used system is expected to be $20 comma 00020,000 in five years, and the market value of the new system is anticipated to be $50 comma 00050,000 in five years. Current maintenance activity will require the used system to be operated 8 hours per day for 20 days per month. If labor costs $4040 per hour and the MARR is 11% per month, which system should be recommended?

Cadbury has a chocolate factory in dunedin, new zealand. for easter, it makes two kinds of “easter eggs”: milk chocolate and dark chocolate. it cycles between producing milk and dark chocolate eggs. the table below provides data on these two products. demand (lbs per hour) milk: 500 dark: 200 switchover time (minutes) milk: 60 dark: 30 production rate per hour milk: 800 dark: 800 for example, it takes 30 minutes to switch production from milk to dark chocolate. demand for milk chocolate is higher (500lbs per hour versus 200 lbs per hour), but the line produces them at the same rate (when operating): 800 lbs per hour. a : suppose cadbury produces 2,334lbs milk chocolate and 1,652 lbs of dark chocolate in each cycle. what would be the maximum inventory (lbs) of milk chocolate? b : how many lbs of milk and dark chocolate should be produced with each cycle so as to satisfy demand while minimizing inventory?
