1. Consider a machine in our smart factory model (Machine ID=10). The machine just completed a job and it now must choose one of the 4 jobs waiting in its queue. The information of waiting jobs is summarized below.

Job	A(1): Creation Time	A(2): Job Type	A(3): Position in operation sequence
1	2	1	3
2	15	5	1
3	22	7	4
4	49	4	3

1. What is the current location of the machine (in xy coordinates)?

2. Assume that current_type(10) is 4 and the setup time (setup variable in our model) is 10. Find the processing time (including setup time) for each of the four jobs if the job is chosen for next processing.

3. Choose one job according to the following rules.

• Arrival Time (AT)
• Minimum Setup Time (MSetT)
• Most Remaining Operations (MRO)
• Shortest Processing Time (SPT)
