Process Analysis (35 points). SNMO Co. recently won a contract to refurbish Zambonis (a Zamboni is a machine used to resurface ice for skating). The process used by SNMO Co. is a novel one, in which they use a conveyor belt to move a Zambonis through the refurbishment process, in sequence. The Zamboni refurbishment process consists of the following five steps: Step Description Time required per Zamboni 1 1.0 minutes Register Zamboni Unhook water pipes 2 1.5 minutes 3 Scrub and clean 0.8 minutes 4 1.0 minutes Reconnect water pipes Polish and pack 5 1.2 minutes Each step is staffed by a single resource (a former hockey player) that works 40 hours per week. Question 14 2 pts (a) What is the flow time of the entire process for a Zamboni in minutes? Question 15 3 pts (b) What is the maximum number of Zambonis that SNMO Co. can refurbish in a single week assuming 5 former hockey players work there? Question 16 3 pts (c) Which step (resource) is the bottleneck? O Step 1 (Register Zamboni) Step 2 (Unhook water pipes) O Step 3 (Scrub and clean) Step 4 (Reconnect water pipes) O Step 5 (Polish and pack) Because many people have started to build their own hockey rinks (due to the pandemic), the demand for refurbished Zambonis is 600 per week. SNMO Co. satisfies the demand exactly. Question 17 3 pts (d) What is the throughput rate of the process? Please state your answers in the units of Zambonis per week. Question 18 3 pts (e) What is the utilization of the first worker (your answers should be stated as a number between 0 and 1)? Question 19 4 pts (f) What is the average utilization of the 5 former hockey players (resources) during this week (your answers should be stated as a number between 0 and 1)? Question 20 4 pts (g) If you can add 1 former hockey player to the system, to work on any of the steps in parallel to an existing former player, where would you add the new worker? O Step 1 (Register Zamboni) Step 2 (Unhook water pipes) O Step 3 (Scrub and clean) Step 4 (Reconnect water pipes) Step 5 (Polish and pack)
