Group Assignment #2 1) What is the utilization at each step of the process in the clinic? Front Desk: a. Registration: The total availability time = 3*180 = 540 min The total registration time = 80*5 = 400 min (New patient & Follow-up patient) The utilization of Registration = 400/540 = 74.07% b. Verification & Hand-off: Total available time = (4*60 + 15)*3 = 255*3 = 765 min The number of follow-up patients = 80*60% = 48 people The number of new patients = 80*40%

The cycle time is 10 minutes because the bottleneck is the time they have to wait for the cookies to bake in the oven. They cannot continue the cookie process without baking and the lack of room in the oven or additional ovens are the constraints that are limiting the total operation. The capacity of the operation would be 6

She believed that theses were due to outdated manufacturing technology‚ a lack of floor space‚ and multiple bottlenecks in the process‚ specifically in the customization phase. Breen feels that the only way to fix Morrison’s problems and set the company up for success in the future‚ their capacity must increase. In order to increase capacity‚ Breen will need to

Fruit Computer Company manufactures memory chips in lots of ten chips. From past experience‚ Fruit knows that 80% of all lots contain 10% (1 out of 10) defective chips‚ 20% of all lots contain 50% (5 out of 10) defective chips. If a good batch (that is‚ 10% defective) of chips is sent on to the next stage of production‚ processing costs

obtain a stable utilization rate throughout all machines to prevent incurring any late penalty. For example at Day 50‚ before the game started‚ we observed that machine 1 was running at 100% utilization for a few days before‚ and we predicted a bottleneck situation would occur here. Therefore we decided to purchase an additional machine immediately as the game started so as to allow continuous processing of lots to meet the demand and prevent losses in revenue.

How many orders can you fill in a night‚ assuming you are open four hours each night? 4 hours per each night = 4 hours * 60 minutes = 240 minutes Cycle Time = The Duration of the bottleneck = (Setting thermostat and Timer) + (Baking Cookies) = 1 minute + 9 minute = 10 minutes Maximum no of orders we can fill in a night = (No of minutes per night-Duration of First Setup) / Cycle Time + 1 = ((240
