warehouse layout

1. Which warehouse layout is the most suitable for a highly seasonable demand pattern?
2. Show that a warehouse can be modelled as a queueing system.
3. A warehouse stores nearly 20 000 pallets. Pallets turn around about five times a year. How much is the required labour force? Assume two eighthour shifts per day and about 250 working days per year. (Hint: apply Little’s Law stating that for a queueing system in steady state, the average length LQ of the queue equals the average arrival rate ? times the average waiting time TW , LQ = ?TW.)
