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. The role in this contract proposal was to analyze the flow of the product as it went though the manufacturing line. For this exercise, we took a look at four major steps in this process, and used simulation to determine the average length of time it took a single optic to flow through the manufacturing line. This objective was one of many objectives the original analysis was to achieve. We

Unformatted text preview: assumed that there was no queuing and that there were sufficient resources to perform the operations. The four key operations are shown below and the assumed probability distributions for each operation. These operations were done in series; i.e., done sequentially. We Performed the simulation with 50 iterations and computed 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...
