Donner Company Case Overview Donner Company manufactures printed circuit boards for both large and small companies‚ specializing in experimental devices and for pilot production runs in the late 1980s. The circuit boards that it produces are made from thin sheets of narrow metal strips and insulating material. The process to produce each circuit board is very meticulous and involves many intricate steps. Their process‚ otherwise known as the “soldermask over bare copper” (SMOBC) process includes

Order Size for drilling: * The Manual press needs 15 min for set up‚ in addition to 0.08 min for every hole. Knowing that the typical circuit board has 500 drilled holes‚ then run time will be 0.08*500 = 40 min / board. Therefore‚ time taken to drill N boards manually will be equal to : 15 + 40(N) * On the other hand the CNC drill needs 240 min for set up‚ in addition to 0.004 min for every hole. So run time will be 0.004*500 = 2 min / board. Then the time taken to drill N boards by CNC drill

Case: Donner Company EXECUTIVE SUMMARY The Donner Company is a manufacturer of printed circuit boards. They need to address several issues in their supply chain operations to improve their service level because net income in the month of September has drastically decreased. Before September‚ growth was steadily increasing every month. They found that the major problems include unpredictable bottlenecks in manufacturing‚ lower than expected productivity and lower than expected quality
