Quantitative Method Simulation Problem for Kodak

See attached template.

Optics Manufacturing

In the late 90's Kodak was bidding for a contract with a major research facility on the West Coast to build large-scale optics for the National Ignition Facility. These optics were roughly two feet by two feet and had to be of extremely high quality. My role in this contract proposal was to analyze the flow of the product as it went though the manufacturing line. For this exercise, we will take a look at four major steps in this process, and use simulation to determine the average length of time it takes a single optic to flow through the manufacturing line. This objective was one of many objectives the original analysis was to achieve. We will assume that there is no queuing and that there are sufficient resources to perform the operations. The four key operations are shown below and the assumed probability distributions for each operation. These operations are done in series; i.e., done sequentially. Perform the simulation with 50 iterations and compute the average service (time to complete an optic) for all 50 iterations from Grinding through Cleaning.

Operation Time Required Probability

Grinding 5 min 0.20

7 min 0.40

10 min 0.40

Machining 10 min 0.20

20 min 0.40

30 min 0.30

50 min 0.10

Polishing 15 min 0.4

20 min 0.4

30 min 0.2

Cleaning 10 min 0.30

15 min 0.40

20 min 0.30.
