RT =I
Rp = c/Tp
U = R/Rp
EOQ=SQRT(2DS/H)
Ordering Cost (OC) = SD/Q
Carrying Cost (CC) = HQ/2
Total Cost (TC) = SD/Q+HQ/2
If you see the term “capacity waste factor”, just ignore it.
“Capacity” and “Effective Capacity” are the same terms.
Cycle Time = CT= 1/Rp
Takt Time = TT=1/R
SL*=Cu/(Cu+Co)
Cycle Inventory = Q/2
Average Inventory in the presence of Safety Stock = Cycle Inventory + IsafetyThere are four resources in a medical billing process. The unit load (Tp) of each resource unit to process one flow unit (a medical bill) is given below: Mailroom Clerk 7 min. Data-entry clerk 6 min. Claim processor 18 min. Claim supervisor 20 min. These numbers already include capacity waste factors. There are 2 resource units in the mailroom clerk resource pool, 5 resource units in the data-entry clerk resource pool, 2 resource units in the claim processor resource pool, and 3 resource units in the claim supervisor resource pool. Process utilization is 0.6. (Hint: you do not need utilization in computing capacities.)

Flag question: Question 3Question 33.5 pts
There are three sequential operations (Station 1, Satiation 2, and Station 3) in a process. Incoming applications go to station 1 first, then to Station 2, finally to station 3, and then leave the process. There are 2 resources in Station 1, 3 resources in Station 2, and 3 resources in Station 3. The HOURLY capacity of EACH SINGLE RESOURCE in these resource pools is 20 , 10 , and 15, respectively. The last 3 numbers are the capacity of a single machine in each of the three stations, respectively.

Flag question: Question 8Question 87 pts
A large distributor has 4 retail outlets. Currently each outlet manages its ordering independently. Demand at each retail outlet averages 1600 per day. Assume there are 250 days per year. Each unit of product costs 160 dollars, and holding cost per unit of product per year is 16% of the product cost. The fixed cost of each order (administrative plus transportation) is 1200 dollars in the decentralized system. The fixed cost of each order in the centralized system is twice of the decentralized system. Holding cost per unit are the same in the two systems.
1. How much does EACH warehouse need to order individually to minimize the total cost in the DECENTRALIZED system?
The potential answers are:
A: 3904 units.
B: 6124 units.
C: 4000 units.
D: 7746 units.
E: 7906 units.
2. How much should ALL the warehouses order together to minimize the total cost in the CENTRALIZED system?
The potential answers are:
A: 19365 units.
B: 12344 units.
C: 17321 units.
D: 12649 units.
E: 26833 units.
