1. Problem 13.9
   1. Mary who is operations manager at a furniture store has received the following estimates of demand requirements.

      July	Aug	Sept	Oct	Nov	Dec
      1000	1200	1400	1800	1800	1600

      1. Assuming stockout costs for lost sales of $100 per unit, inventory carrying costs of $25 per unit per month, and zero beginning and ending inventory, evaluate these two plans on as incremental cost basis.
         1. Plan A: Produce at a steady rate ( equal to minimum requirements) of 1,000 units per month and subcontract additional units at $60 per unit premium cost
         2. Plan B: Vary the workforce, which performs at a current production level of 1,300 units per month. The cost of hiring additional workers is $3,000 per 100 units produced. The cost of layoffs is $6,000 per 100 units cut back.
      2. Which plan is best and why?
2. Problem 13.10
   1. Use problem above…..mary is considering two more mixed strategies. Using the data compare plans C and D with plans A and B and make a recommendation
      1. Plan C: Keep the current workforce steady at a level producing 1300 units per month. Subcontract the remainder to meet demand. Assume that 300 units remaining from June are available in July.
      2. Plan D- Keep the current workforce at a level capable of producing 1300 units per month. Permit a maximum of 20% overtime at a premium of $40 per unit. Assume that warehouse limitations permit no more than a 180 unit carryover from month to month. This plan keeps that any time inventories reach 180 the plant is kept idle. Idle time per unit is $60 per incremental unit.
         Solution: Now we get

         PLAN C
         Period	Demand	Production	Inventory (end of period) ($25)	Sub contract ($60)
         June		1300	0
         July	1000	1300	300	0	$7,500.00
         August	1200	1300	400	0	$10,000.00
         September	1400	1300	300	0	$7,500.00
         October	1800	1300	0	200	$12,000.00
         November	1800	1300	0	500	$30,000.00
         December	1600	1300	0	300	$18,000.00
         				Extra Cost =	$85,000.00

3. Problem 15.3
   1. The orange top cab company has a taxi waiting at each of four cabstands in Evanston illiniois. Four customers have called and requested service. The distances, in miles, from the waiting taxis to the customers are given in the following rable. Find the optimla assignment of taxis to customers so as to minimize total driving distances to the customers.

4) The following jobs are waiting to be processed at your work center, which cleans valve body castings. Job numbers are assigned sequentially upon arrival in the facility (a missing number means that job does not require your work center). All dates are specified as days from Today.

a. In what sequence should the jobs be processed according to the FCFS scheduling rule?

b. In what sequence should the jobs be processed according to the EDD scheduling rule?

c. In what sequence should the jobs be processed according to the SPT scheduling rule?

d. In what sequence should the jobs be processed according to the LPT scheduling rule?

e. In what sequence should the jobs be processed according to the critical ratio scheduling rule?
