Explain how inventory and investment management are related to this example regarding Discount rate/cost, Warranty period, NPV, etc.?

Step 1:

Simulation Model:

Warranty costs for camera
Inputs
Parameters of time to failure distribution of any new camera (Gamma)
Desired mean	2.5
Desired stdev	1
Implied alpha	6.250
Implied beta	0.400
Warranty period	1.5
Cost of new camera (to customer)	$400
Replacement cost (to company)	$225
Discount rate	8%
Simulation of new camera and its replacements (if any)
Camera	1	2	3	4	5
Lifetime	2.442	NA	NA	NA	NA
Time of failure	2.442	NA	NA	NA	NA
Cost to company	0	0	0	0	0
Discounted cost	0.00	0.00	0.00	0.00	0.00
Failures within warranty	0
NPV of profit from customer	$175.00

Simulation Results:

Failures within warranty simulation results:

NPV of profit from customer simulation results:

Step 2: Week 5 Reflection

This week I learned what a simulation model is and how a distribution model is used in running simulations. I learned that a distribution can be continuous (meaning all continuous values in a distribution range) or discrete (meaning a discrete set of values in a distribution range). I learned how to use the RISK tools in excel to run a simulation which I captured the output above. I learned about the flaw of averages and how it impacts simulations. I also learned how the input variables distribution varies allow for multiple simulation runs or scenarios.

This weeks assignments took me about 8-10 hours.
