In the attacks on the World Trade Center alone on September 11th, 2001, there were 2,606 deaths, and over 6,000 injuries. Assume a worker is injured as she is escaping from the building before the collapse.
1) Would she be able to file a worker's compensation claim for a job-related injury due to terrorist attacks?
2) Are terrorist attacks foreseeable by businesses operating in tall buildings?
3) What of the victims of the San Bernadino attacks in 2015, are those workers eligible for worker's compensation?
4) Would the employee be able to sue her employer because of their failure to provide adequate safeguards for a terrorist or mass shooting?

Hart Manufacturing makes three products. Each product requires manufacturing operations in three departments: A, B, and C. The labor-hour requirements, by department, are as follows:
| Department | Product 1 | Product 2 | Product 3 |
| A | 3.00 | 2.00 | 1.50 |
| B | 1.00 | 2.50 | 2.00 |
| C | 0.25 | 0.25 | 0.25 |
During the next production period the labor-hours available are 450 in department A, 350 in department B, and 50 in department C. The profit contributions per unit are $28 for product 1, $30 for product 2, and $25 for product 3.

Step 1 Picture yourself as a Senior Product Manager in your
favorite industry. This could be high-tech, financial services,
consumer products, electronics, automobiles, restaurants, food
services, etc. Choose an industry with which you are familiar. Sit
quietly and brainstorm with yourself about a possible new product
idea. This does not have to be completely original. It could be as
simple as a new flavor of ice cream, a new feature on a hair dryer
or a new color iPod/iPad.
Step 2 Create a post describing your new product idea. Be as specific as possible and provide as much detail as you can so that other's reading your post can understand your idea in sufficient detail so as to comment on it. Be sure to state who the product idea is targeted to, that is, who you expect to buy it. How will the new product compare and compete with similar, currently available products? How can labeling and package design help? Consider the labeling for the new product idea. What restrictions and legal requirements have to be fulfilled? Consider the packaging for the new product ideas. If applicable, what sizes will be available? How will the packaging help the product to stand out? How will the packaging help prevent or deter theft? Feel free to attach images to your post, or include links to similar products that might have similar characteristics to the new one you are developing.

Have you had a frustrating experience with customer support? Let's say you receive a promotion from your cable company offering you a month of free HBO. Then they bill you for it. You call customer service and they say it’s a marketing promotion so you need to call marketing. Marketing tells you to call billing. Billing says they never heard of any such promotion. Are you ready to bang your head against the wall? Why did this happen?

The Bijou Theater shows vintage movies. Customers arrive at the
theater line at the rate of 80 per hour. The ticket seller averages
36 seconds per customer, which includes placing validation stamps
on customers’ parking lot receipts and punching their frequent
watcher cards. (Because of these added services, many customers
don’t get in until after the feature has started.) (Use the Excel
spreadsheet Queue Models.)
a. What is the average customer time in the
system? (Round your answer to 2 decimal
places.)
|
b. What would be the effect on customer time in the system of having a second ticket taker doing nothing but validations and card punching, thereby cutting the average service time to 25 seconds? (Round your answer to 3 decimal places.)
Average time in system ________ minutes
c. What would be the customer time in the system if instead of the change in Part b, a second window was opened with each server doing all three tasks? (Do not round intermediate calculations. Round your answer to 3 decimal places.)

d. Would system waiting time which is obtained in part (c) be less than you found in (b)?
Yes

Roedel Electronics produces tablet computer accessories, including integrated keyboard tablet stands that connect a keyboard to a tablet device and hold the device at a preferred angle for easy viewing and typing. Roedel produces two different sizes of integrated keyboard tablet stands, small and large. Each size uses the same keyboard attachment, but the stand consists of two different pieces, a top flap and a vertical stand that differ by size. Thus, a completed integrated keyboard tablet stand consists of three subassemblies that are manufactured by Roedel: a keyboard, a top flap and a vertical stand.
Roedel's sales forecast indicates that 7,000 small integrated keyboard tablet stands and 5,000 large integrated keyboard tablet stands will be needed to satisfy demand during the upcoming Christmas season. Because only 500 hours of in-house manufacturing time are available, Roedel is considering purchasing some, or all, of the subassemblies from outside suppliers. If Roedel manufactures a subassembly in-house, it incurs a fixed setup cost as well as a variable manufacturing cost. The following table shows the setup cost, the manufacturing time per subassembly, the manufacturing cost per subassembly, and the cost to purchase each of the subassemblies from an outside supplier:
| Manufacturing | ||||
| Subassembly | Setup Cost ($) | Time per Unit (min.) | Cost per Unit ($) | Purchase Cost per Unit ($) |
| Keyboard | 1,000 | 0.9 | 0.40 | 0.65 |
| Small top flap | 1,200 | 2.2 | 2.90 | 3.45 |
| Large top flap | 1,900 | 3.0 | 3.15 | 3.70 |
| Small vertical stand | 1,500 | 0.8 | 0.30 | 0.50 |
| Large vertical stand | 1,500 | 1.0 | 0.55 | 0.70 |

| (b) | Suppose Roedel is considering purchasing new machinery to produce large top flaps. For the new machinery, the setup cost is $3,000; the manufacturing time is 2.5 minutes per unit , and the manufacturing cost is $2.60 per unit. Assuming that the new machinery is purchased, determine how many units of each subassembly Roedel should manufacture and how many units of each subassembly Roedel should purchase. If an amount is zero, enter “0”. | |||||||||||||||||||||

The Dolomite Corporation is making plans for a new factory. One department has been allocated 12 semiautomatic machines. A small number (yet to be determined) of operator will be hired to provide the machines the needed occasional servicing (loading, unloading, adjusting, setup, and so on). A decision now needs to be made on how to organize the operators to do this. Alternative 1 is to assign each operator to her own machines. Alternative 2 is to pool the operators so that any idle operator can take the next machine needing servicing. Alternative 3 is to combine the operators into a single crew that will work together on any machine needing servicing. The running time (time between completing service and the machine’s requiring service again) of each machine is expected to have an exponential distribution, with a mean of 150 minutes. The service time is assumed to have an exponential distribution, with a mean of 15 minutes (for Alternatives 1 and 2) or 15 minutes divided by the number of operators in the crew (for Alternative 3). For the department to achieve the required production rate, the machines must be running at least 89 percent of the time on average.
(a) For Alternative 1, what is the maximum number of machines
that can be assigned to an operator while still achieving the
required production rate? What is the resulting utilization of each
operator?
(b) For Alternative 2, what is the minimum number of operators
needed to achieve the required production rate? What is the
resulting utilization of the operators?
(c) For Alternative 3, what is the minimum size of the crew needed
to achieve the required production rate? What is the resulting
utilization of the crew?
