The engine manufacturer has observed that their engine control modules (ECM) fail as a direct function of how many hours they are active. The mean time between failures for the ECM is 50,000 operating hours. Accounting has determined that the company cannot profitably afford to pay for the repair of more than 12% of the ECM modules produced.
What do you estimate to be the maximum acceptable warranty
period (in operating hours) so that the company does not end up
having to exceed the guidance for acceptable fraction of units
repaired under warranty?

An engine manufacturer has observed
failures with their product. In the last 6 years, they have
experienced 2 engine failures one year, 3 engine failures in two
consecutive years, 4 engine failures one year, and 5 engine
failures in each of the preceding two years (two in the last month,
alone).
The CEO of the engine manufacturer
wants to reassure customers. He promises that in the next month,
there will not be multiple engine failures (no more than 1
failure)....

An environmentally progressive small manufacturer in South
Dakota has observed that her gas bill in February (the coldest
month of the year) is usually about $900 (for space heating only).
She uses a large natural gas space heater whose efficiency is known
to be about 89%. She is considering upgrading to a furnace that
uses a water source heat-pump with a coefficient of performance of
4.2. The heat-pump operates on 240 VAC electricity. Furthermore,
she plans to install a wind...

Lakeview Engine, Inc., produces engines for the watercraft
industry. An outside manufacturer has offered to supply several
component parts used in the engine assemblies, which are currently
being produced by Lakeview. The supplier will charge Lakeview $320
per engine for the set of parts. Lakeview’s current costs for those
part sets are direct materials, $160; direct labor, $75; and
manufacturing overhead applied at 100% of direct labor. Variable
manufacturing overhead is considered to be 20% of the total, and
fixed...

6.5 An engine manufacturer has decided to change one of its
engines from a spark ignition type to a compression ignition type.
If the swept volume is unchanged, what effect will the change have
on:
(i) maximum torque?
(ii) maximum power?
(iii) the speed at which maximum power occurs?
(iv) economy of operation?

A electronics manufacturer has developed a new type of remote
control button that is designed to operate longer before failing to
work consistently. A random sample of 28 of the new buttons is
selected and each is tested in continuous operation until it fails
to work consistently. The resulting lifetimes are found to have a
sample mean of ?¯x¯ = 1254.6 hours and a sample standard deviation
of s = 109.1. Independent tests reveal that the mean lifetime of
the...

A Manufacturer of flash drives has a profit function of
P= t - q2where t is the price charged
for a flash drive and q2 is the cost of producing a
drive whose capacity is q gigabytes. A consumer of type
'x' has a utility function of u =
xq-t, where 'x' takes on the value of 8 for
H-type consumers or 6 for L-type consumers. There are 100 consumers
of each type. A consumer gets zero utility if she...
