2. Prepare a network diagram for this project. The standard working week is 40 hours working Monday through Friday, 8 hours each day. Tasks with duration not dependent on resources assigned are listed as calendar day duration. An example is awaiting arrival of a part in shipment from a supplier. a a e g e Activity Immediate Predecessor Resource Need /Duration 80 person hours b 48 person hours b 80 person hours d 112 person hours sd 3 calendar days f d 128 person hours ef 48 person hours h 48 person hours i g.h 64 person hours j i 4 calendar days k j 32 person hours In solving you will also have to work with a calendar and develop a Gantt chart as well over the calendar several times to answer the questions because of weekends not being worked and calendar day length of some activities. For tasks with calendar day durations weekend days count as 'days worked', weekends are not counted as days worked for staffed tasks. a) What is the EF (the day on which the project is completed) in calendar days from the start at the beginning of Tuesday of the project if 2 workers are assigned to every activity? Partial days on an activity are allowed and activities can start during any day. Calendar days includes counting weekend days when no work is completed on the project. So a project begun on Wednesday that required 4 days of work would be finished at the end of Monday of the following week making it finished after 6 calendar days. b) Using 2 workers per activity as in part a, what is the TS of Activity h if the due date is close of business on the Wednesday of the last week that work is done? (hint, don't forget about weekends!) c) In the part a staffing level of 2 workers to each task, if the desire was to have a start date for activity c on the 7th calendar day after starting the project (Monday of the second week, using the first convention) how many workers would be required to be assigned to activity a? d) What is the EF in calendar days if 2 workers for tasks as before except now 3 workers are assigned to activities g and h, 1 worker is assigned activity k, and 4 workers assigned to activity f? e) Using the staffing from part d, more workers have been added to the project. If 5 workers were available to work on activity a and 4 on what is the EF of the project in calendar days
