Question

The following table gives the operation times and due dates for five jobs that are to be processed on a machine. Assign the jobs according to the shortest operation time and calculate the mean flow time.

Job	Processing Time	Due Date (Days Hence)
101 102 103 104 105	6 days 7 days 4 days 9 days 5 days	5 3 4 7 2

Short answer

The mean flow time using the shortest process assignment rule is 18.6.

Step-by-step solution

Introduction

The mean is a statistical indicator that can be used to gauge the performance of a company's stock price for days, months, or years; a company's earnings for years; a firm by assessing its fundamentals such as price-to-earnings ratio, free cash flow, and liabilities on the balance sheet; and a portfolio by estimating its average returns over a certain period.

Find mean

Calculation of mean flow time:

$\mathrm{Flowtime}=\mathrm{Processingtimeofcurrentjob}+\mathrm{Processingtimeofpreviousjob}$
