Tej Dhakar's company wants to establish kanbans to feed a newly established work cell. The following data have been provided. How many kanbans are needed?

Daily demand	250 units
Lead time	$\frac 12$day
Safety stock	$\frac 14$day
Kanban size	50 units

Temple Trucking Co, just hired Ed Rosenthal to verify daily invoices and accounts payable. He took 9 hours and 23 minutes to complete his task on the first day. Prior employees in this job have tended to follow a $90 \%$ learning curve. How long will the task take at the end of the 2nd day?

Even though independent gasoline stations have been having a difficult time, Ian Langella has been thinking about starting his own independent gasoline station. Ian's problem is to decide how large his station should be. The annual returns will depend on both the size of his station and a number of marketing factors related to the oil industry and demand for gasoline. After a careful analysis, Ian developed the following table:

For example, if Ian constructs a small station and the market is good, he will realize a profit of $\$ 50,000$.

What is the equally likely decision?

Jerry Bildery's factory is considering three approaches for meeting an expected increase in demand. These three approaches are increasing capacity, using overtime, and buying more equipment. Demand will increase either slightly $(S)$, moderately $(\mathrm{M})$, or greatly $(\mathrm{G})$. The profits for each approach under each possible scenario are as follows:

Since the goal is to maximize, and Jerry is risk-neutral, he decides to use the equally likely decision criterion to make the decision as to which approach to use. According to this criterion, which approach should be used?

Andrew Thomas, a sandwich vendor at Hard Rock Cafe's annual Rockfest, created a table of conditional values for the various alternatives (stocking decision) and states of nature (size of crowd):

The probabilities associated with the states of nature are $0.3$ for a big demand, $0.5$ for an average demand, and $0.2$ for a small demand.

Compute the expected value of perfect information (EVPI).

Given the following conditional value table, determine the appropriate decision under uncertainty using maximin.

The required number of kanbans equals:

a) 1.

b) Demand during lead time / $Q$

c) Size of container.

d) Demand during lead time.

e) Demand during lead time $+$ Safety stock/Size of container

Jeffrey Helm owns a health and fitness center called Bulk-Up in Harrisburg. He is considering adding more floor space to meet increasing demand. He will either add no floor space $(\mathrm{N})$, a moderate area of floor space $(\mathrm{M})$, a large area of floor space (L), or an area of floor space that doubles the size of the facility (D). Demand will either stay fixed, increase slightly, or increase greatly. The following are the changes in Bulk-Up's annual profits under each combination of expansion level and demand change level:

Jeffrey is risk averse and wishes to use the maximin criterion.

What should he do?

The first vending machine that William Kine, Inc., assembled took 80 labor-hours. Estimate how long the fourth machine will require for each of the following learning rates:

$$95 \%$$

Girish Shambu and William Reisel are teammates at a discount store; their new job is assembling bicycles for customers. Assembly of a bike has a learning rate of $90 \%$. They forgot to time their effort on the first bike, but spent 4 hours on the second set. They have 6 more bikes to do. Determine approximately how much time will be (was) required for the 1st unit

Which Lean techniques work in both the manufacturing and service sectors?

Richard Dulski's firm is about to bid on a new radar system. Although the product uses new technology, Dulski believes that a learning rate of $75 \%$ is appropriate. The first unit is expected to take 700 hours, and the contract is for 40 units.

What is the total amount of hours to build the 40 units?

What are the components of the following queuing systems? Draw and explain the configuration of each.

If it took Boeing $28,718$ hours to produce the eighth 787 jet and the learning-curve factor is $80 \%$, how long did it take to produce the tenth 787 ?
