Answer:

A) Single-server single-phase model (M/M/1).

\lambda=2.5 \,customers/hour\\\\\mu=6\,customers/hour

B) The goal is not met, as the average time waiting for service is 5.56 minutes.

C) The new mean service rate is 7.5 customers/hour.

In this case, the average time waiting for service is 4 minutes, so the goal is met.

Explanation:

A) This situation can be modeled as a single-server single-phase model (M/M/1).

The mean arrival rate is 2.5 customers per hour.

\lambda=2.5 \,customer/h

The mean service rate is 6 customers per hour, calculated as:

\mu=\frac{60\, min/h}{10 \,min/customer}=6\, customer/h

B) The average waiting time for a customer can be expressed as:

W_q=\frac{\lambda}{\mu}\frac{1}{\mu-\lambda}  =\frac{2.5}{6}\frac{1}{6-2.5} =0.417*0.222=0.093\,hours\\\\W_q=0.093\,hours*(60min/h)=5.56 \,min

The average waiting time is 5.56 minutes, so it is more than the goal of 5 minutes.

C) If the average time spent per customer to 8 minutes, the mean service rate becomes

\mu=\frac{60\, min/h}{8 \,min/customer}=7.5\, customer/h

An the average waiting time for the service now becomes:

W_q=\frac{\lambda}{\mu}\frac{1}{\mu-\lambda}  =\frac{2.5}{7.5}\frac{1}{7.5-2.5} =0.333*0.2=0.067\,hours\\\\W_q=0.067\,hours*(60min/h)=4 \,min

The average time is now 4 minutes, so the goal is achieved.

salantis [7]

Answer:

insurance company will pay $75 to Alfred.

Explanation:

given data

Actual cost of camera = $200

Alfred cost of camera = $150

Life expectancy = 6 years

solution

we get here first Remain life of camera that is

Remain life of camera = 6 years  - 3 years

Remain life of camera = 3 years

and

now we get here current cost of the camera that is

current cost of camera = Alfred cost of camera × (Remain life of camera ÷ Life expectancy)    ........................1

put here value and we get

Current cost of camera = $150   ×   \frac{3}{6}

Current cost of camera = $75

so that insurance company will pay $75 to Alfred.

Brilliant Accents Company manufactures and sells three styles of kitchen faucets: Brass, Chrome, and White. Production takes 25,
stepan [7]

Answer:

1. Using the ABC system, for each style of faucet, compute the estimated overhead cost per unit.

Brass = [(30 x $4,900) + (900 x $150)] / 30,000 units = $9.40 per unit

Chrome = [(25 x $4,900) + (1,000 x $150)] / 50,000 units = $5.45 per unit

White = [(40 x $4,900) + (800 x $150)] / 40,000 units = $7.90 per unit

2. Compute the estimated operating profit per unit.

Brass = $40 - $8 - $15 - $9.40 = $7.60

Chrome = $20 - $4 - $3 - $5.45 = $7.55

White = $30 - $8 - $9 - $7.90 = $5.10

Explanation:

cost per setup = $465,500 / 95 = $4,900 per setup hour

cost per inspection = $405,000 / 2,700 = $150 per inspection hour

                                               BRASS      CHROME     WHITE

Projected sales in units        30,000        50,000      40,000

Per unit data: Selling price     $40              $20            $30

Direct materials                        $8                 $4              $8

Direct labor                             $15                 $3              $9

Setup hours                              30                 25             40

Inspection hours                    900             1,000           800
