Use the parallel method and heuristics given. a) What is the project duration after resource levelling? (Write the duration only, do not add any unit, for example, if your answer is 50 days, write 50 only. Use the first input box) [15 marks] b) Recompute your slack for each activity given your new schedule. What is the slack for activity D? (Write the duration only, do not add any unit, for example, if your answer is 50 days, write 50 only. Use the second input box) [5 marks] c) How many resources have you scheduled between week 7 to 9? (Use the third input box) [5 marks] Use the following heuristics: Minimum slack Smallest duration Lowest identification number 0A1 4 14 4 15 0B2 1 1 1 2 D4 3 13 5 27 7F9 020 1 2 3 7 29 0C3 3 E7 020 34 7 010 03 3 ID RES DUR ES LF SL O A 1 1 B 1 2 C 13 D 1 2 E F 2 2 24 3 4 Resources scheduled Resources available 2 2 2 2 2 2 S 5 Legend ES ID EF SL RES SL LS DUR LF 6 2 2 2 2 2 10 11 12 13 2 2
