1. Streets in Bellevue are maintained by Public Works Division; "Street Maintenance". Public Works administrators are planning the workforce of this division for next year. Labor hour requirements for the next year are 8,000, 14,000, 29,000, and 18,000, for quarters 1 to 4 respectively. Each of the current 15 workers on the workforce can contribute 500 hours per quarter. Overtime is limited to 20 percent of the regular-time capacity in any quarter. Subcontracting is not permitted. Payroll costs are $7,000 in wages per worker for regular time worked up to 500 hours, with an overtime pay rate of $21 for each overtime hour. Although unused overtime capacity has no cost, unused regular time is paid at $14 per hour. The cost of hiring a worker is $3,500, and the cost of laying off a worker is $2,800. a. Find a level workforce plan that uses overtime and the minimum amount of undertime (idle time for workers) possible. Overtime can be used to its limits (20%). What is the total cost of this plan? b. Plan for a chase strategy to with variable workforce levels adjusted each quarter. What is the total cost of this plan? c. Propose a mix strategy. Compare your plan to plans "a" and "b" and show the differences. Is your plan better than plan "a" or "b"? Why or why not? PUT ALL YOUR ANSWERS IN THE ACCOMPANYING WORD DOCUMENT TEMPLATE. 1. (a) Write a DOS Batch script to automatically recursively backup files from a specified directory (and all its sub-directories), to a newly create directory called BackupFolder (with the same sub-directories). Finally list all the files recursively in the new BackupFolder. Provide screengrabs of the script file, a directory listing before you run the script, a directory listing after you run the script, and at least 150 words explaining how you figured out how to make this work, and what each command does. 1. (b) Write a Bash/Linux script to automatically recursively backup files from a specified directory (and all its sub-directories), to a newly create directory called BackupFolder (with the same sub-directories). Finally list all the files recursively in the new BackupFolder, and what each command does. Provide screengrabs of the script file, a directory listing before you run the script, a directory listing after you run the script, and at least 150 words explaining how you figured out how to make this work. 1. (c) The Little Man model uses a single-digit op-code and a 2-digit memory addressing and has the following instructions defined where the address portion is shown as xx OpCode Instruction Description 1xx ADD Add the value of a given memory location to calculator 2xx SUBTRACT Subtract the value of a given memory location to calculator 3xx STORE Copy the value from the calculator into a given memory location 5xx LOAD Copy the value from a given memory location into the calculator 6xx BRANCH Unconditional branch. Set the Program Counter to value xx 7xx BRANCH IF ZERO Conditional branch. If the accumulator is zero, branch to xx 8xx BRANCH IF POSITIVE Conditional branch. If the accumulator is positive, branch to xx 901 INPUT Get the value from the IN-TRAY and put it into the calculator 902 OUTPUT Put the value in the calculator into the OUT-TRAY 000 HALT Take a break Write a program using these codes to take two numbers which are contained in the IN-TRAY and display the sum (+) of those numbers in the OUT-TRAY.
