Create a minimum cost chase plan for the forecast shown in the table. There is no beginning inventory and regular production capacity is 350 units. Overtime costs $20 and is limited to 50 units per month and subcontracting is limited to 100 units per month and costs $15 per unit. What is the total plan cost (i.e. subcontracting + overtime)?

Hint: In a chase production plan, production is changed each time period to match the demand. Use regular production, overtime, and subcontracting to create the plan.

Month	Forecast	Regular	Overtime	Subcontracting
January	250
February	400
March	500
April	350

3) A firm wishes to assign a set of jobs to a set of machines. The table below provides data on the cost of production of each job when performed on a specific machine.

a) Determine the set of assignments that minimizes production cost.

b) What is the total production cost of your assignments?

	Machine
Job	A	B	C	D
1	27	29	28	30
2	30	29	27	26
3	31	25	29	26
4	29	31	25	28

4) Using the information given in the table, find the sequence for the following priority rules:

a) SPT

b) EDD

c) LPT

Job	Process Time	Due Date
A	6	10
B	4	2
C	8	5
D	9	16
