Assume that you are a quality inspector for a manufatcuring company. Every day you take a random sample of 10 parts (items) of finished products and inpsect the items to see if there is any defective item. If you found any defective item, then you send it to the rework station for recovery. Based on the past historical data, we know that there is 15% chance that an item to be defective. There is a rework cost associated with each defective item. The rework cost is following Uniform distribution with parameters of $30 and $50.

A company produces two very similar products that go through a three-step sequence of fabrication,assembly, and packaging. Each step requires one day for a lot to be completely processed and movedto the next department. Processing requirements for the departments (hours per unit) are as follows.FABRICATION ASSEMBLY PACKAGINGProduct Labor Machine Labor Machine Labor MachineA 2 1 1.5 1 1 .5B 1 1 1 1 1.5 .5Department capacities are all 700 hours of labor and 500 hours of machine time, except Friday,when capacities are 200 hours for both labor and machine time.

Question: The Thermiston production plant's equipment operates two shafts for eight hours and produces 100,000 pieces per day. The design time for producing a thousand pieces was 6.88. The last quarter of an hour is allocated for daily maintenance and the first quarter of an hour for operation. The time for unexpected malfunctions in the shaft was 20 minutes. If there were 1,000 defective units per shelf, what is the overall effectiveness of the laboratory equipment for that day?

You are the division manager of Sellwell Co.—a firm that has developed an inexpensive chemical spe cialty that you hope will find a huge market as a household product. You want to package this product in 1 L and 2 L sizes. A number of container materials would appear to be practical—glass, aluminum, treated paper, steel, and various types of plastic. A young engineer whom you hired recently and assigned to the packaging department has done a container-disposal study that shows that the disposal cost for 2 L con tainers can vary by a factor of three—depending on the weight of the container, whether it can be recycled, whether it is easy to incinerate, whether it has good landfill characteristics, etc. Your company’s marketing expert believes that the container material with the highest consumer ap peal is the one that happens to present the biggest disposal problem and cost to communities. He estimates that the sales potential would be at least 10% less if the…
An airport needs a modern material handling system for facilitating access to and from a busy maintenance hangar. A second-hand system will cost $75,000. A new system with improved technology can decrease labor hours by 20% compared to the used system. The new system will cost $150,000 to purchase and install. Both systems have a useful life of ﬁve years. The market value of the used system is expected to be $20,000 in ﬁve years, and the market value of the new system is anticipated to be $50,000 in ﬁve years. Current maintenance activity will require the used system to be operated 8 hours per day for 20 days per month. If labor costs $40 per hour and the MARR is 1% per month, which system should be recommended?
