a

Summary Introduction

Interpretation:Current values of mean and the MAD of monthly demand is to be determined.

Concept Introduction:

Exponential smoothing is used to recursively update the estimates of the mean and standard deviation of demand. The standard deviation is estimated using the mean absolute deviation (MAD).

b

Summary Introduction

Interpretation:Current values of mean and standard deviation of lead time demand are to be determined.

Concept Introduction:

Normal distribution is the probability function with continuous series. It is bell shaped distribution function where mean, median and mode are same.

Exponential smoothing is used to recursively update the estimates of the mean and standard deviation of demand. The standard deviation is estimated using the mean absolute deviation (MAD).

c

Summary Introduction

Interpretation:Current values of mean and standard deviation of lead time demand when ordered from Japan are to be determined.

Concept Introduction:

Exponential smoothing is used to recursively update the estimates of the mean and standard deviation of demand. The standard deviation is estimated using the mean absolute deviation (MAD).

d

Summary Introduction

Interpretation:Value of reorder is to be determined.

Concept Introduction:

Exponential smoothing is used to recursively update the estimates of the mean and standard deviation of demand. The standard deviation is estimated using the mean absolute deviation (MAD).

what is the arithmetic average annual return per year?
Describe a simple sales information system for an online store, including its products, branches, and its appraisal, so that it captures the attention of an average person without a university degree or a particular career, and develop a report about it.
Note: A waiting line model solver computer package is needed to answer these questions. The Kolkmeyer Manufacturing Company uses a group of six identical machines, each of which operates an average of 23 hours between breakdowns. With randomly occurring breakdowns, the Poisson probability distribution is used to describe the machine breakdown arrival process. One person from the maintenance department provides the single-server repair service for the six machines. Management is now considering adding two machines to its manufacturing operation. This addition will bring the number of machines to eight. The president of Kolkmeyer asked for a study of the need to add a second employee to the repair operation. The service rate for each individual assigned to the repair operation is 0.40 machines per hour. (a) Compute the operating characteristics if the company retains the single-employee repair operation. (Round your answers to four decimal places. Report time in hours.) La = L = Wa W = h…
