De Law Construction has a gotten some construction jobs to build some starter housing units in a few areas. The building time for each housing unit to be completed as well as the date that each unit is to be completed is shown in the table below. Today is Day 471. Which of the sequences, EDD OR SPT should the company use to sequence the order in which they do the jobs, assuming that because of resource constraints it cannot do the jobs simultaneously? HOUSING UNIT Building Time (days) Due Date Marabella 39 Day 502 Tabaquite 23 Day 528 San Juan 30 Day 515 Mayaro 33 Day 498 D’Abadie 41 Day 535 Preysal 40 Day 510 Some time after starting the jobs according to the sequence you decided on, it was found that because of inclement weather the last three housing units in the sequence have been delayed. You now have to prioritise and decide in which order to expedite those three jobs, using the Critical Ratio model. It is now Day 495. In what order should those three jobs be expedited?

A nursing home must schedule nurses in a manner that balances providing adequate patient care while keeping costs down. From historical records, administrators can project the minimum number of nurses to have on hand during each day/time slot. This data is shown below. Shift Time Slot Minimum number of nurses needed 1 12 am-4 10 2 4 am-8 6 3 8 am-12 8 4 12 pm-4 12 5 4 pm-8 10 6 8 pm-12 14 Nurses must start work at the beginning of one of the four-hour shifts (starting as early as 12 am midnight or as late as 8pm evening) and work for eight hours. Nurses who begin working at 8 pm will work until 4 am the next morning. Formulate and solve the nurse-scheduling problem so as to minimize excess stagging while satisfying minimum staffing requrements. What is the value of total excess staffing?
