Consider the following 3-station serial production line: • Station 1 has 5 identical machines with average processing time of 15 min per job. • Station 2 has 12 identical machines with average processing times of 30 min per job. • Station 3 has one machine with average processing time of 3 min per job. a) (6 pts) What are the bottleneck rate, the raw process time and the critical WIP? b) (7 pts) Compute the average cycle time when the inventory level is set at 20 jobs, under the assumptions of i) the best case, ii) the worst case and iii) the practical worst case. c) (7 pts) Suppose you want the throughput of the line to be 90% of the bottleneck rate. Find the WIP level required to achieve this under the assumptions of i) the best case, ii) the worst case and iii) the practical worst case. d) (5 pts) If the cycle time at the critical WIP is 100 minutes, where does performance fall relative to the three cases? Is there much room for improvement?

Alandlord rented an art studio to an artist. under the terms of the signed, written, two-year lease, the artist agreed to pay the landlord $1,000 per month and to assume responsibility for all necessary repairs. after the first year of the lease, the artist assigned the balance of his lease to a sculptor. the landlord approved the sculptor as a tenant and accepted two rent payments from her, and then the landlord sold the building to an investor. the sculptor had made two payments to the investor when an electrical fire broke out in the studio, injuring the sculptor. the fire was caused by faulty wiring. the landlord was aware that there was a dangerous wiring problem when he leased the property to the artist. but when the landlord discovered how costly repairs would be, he decided it would be more profitable to sell the property than to repair it. the problem was not easily discoverable by anyone other than an expert electrician, and the landlord did not tell the artist, the sculptor, or the investor about the problem. the sculptor sues to recover damages for her injuries. from whom can the sculptor recover?
