Score for this attempt: 20 out of 20 Submitted Oct 29 at 10:05pm Dear Students: This is your Homework Quiz 7. Like previous Homework Quizzes it will be graded on a pass-fail basis and we have set it up so that all questions will be graded automatically. Accordingly, you will get your grade right after you submit your work. NOTE that you will see the correct/incorrect answers at that time, but you will see these only ONCE so take a screenshot if you care to have them for later review. You can then assess whether or not to take the test again. 15 out of a total of 20 points will earn you a "pass." A pass will earn you 5 points out of a maximum of 55 points for assignments, team exercises, etc. You may repeat taking this test up to three times before the final due date to earn a "pass." This time, there are no separate PDFs to be uploaded. Best wishes, Prof. T Take the Quiz Again

Concepts and Definitions For each definition, identify the term that best matches it. When improving the resource requirement profile of a schedule, move activities to start at another time by reallocating TF or FF, or extending the schedule duration. Note that this can be particularly challenging when resources are scarce and there is resource contention. Resource leveling A network of activities with precedence relationships, where activities are specified with their durations, as well as the type and number of resources they need. Resource-loaded sche A 'typical' estimate of how long an activity may take Normal duration of an Characteristic of an activity network, that a shorter project duration can have a lower total project cost Time-cost tradeoff Expenses that are tied to work items (e.g., subcontracted work) Direct cost Compensation paid by the contractor to the owner in Liquidated damages

Resource Leveling Consider the following schedule. It is the same as the one you analyzed in your previous homework assignment (so you may want to review your float calculations), but now each activity has resource requirements added. Activity Predecessors Duration (days) Resources per day Start (milestone) - 0 0 A Start 10 2 B Start 5 5 C Start 4 3 D A 3 0 E A 1 3 F C 3 4 G D 4 2 H B, E, F 5 4 Finish (milestone) G, H 0 0

You may come up with several different schedule alternatives. Some of the possible solutions are shown in the following table: Schedule 1 Schedule 2 Schedule 3 Schedule 4 Schedule 5 Schedule 6 Schedule 7 A starts at 0 A starts at 0 A starts at 0 A starts at 0 A starts at 0 A starts at 0 A starts at 0 B at 0 B at 4 B at 0 B at 0 B at 7 B at 4 B at 0 C at 5 C at 0 C at 5 C at 5 C at 0 C at 0 C at 5 E at 10 E at 10 E at 10 E at 10 E at 12 E at 11 E at 11 F at 9 F at 9 F at 9 F at 9 F at 4 F at 9 F at 9 G at 11 G at 13 G at 12 G at 13 G at 13 G at 12 G at 13 2.1 Analyze each schedule alternative and decide if it keeps the project duration as short as possible while also respecting the daily resource constraint ( "Feasible" ) or if it does not ( "Infeasible" ).

Resource Leveling... 2.2 Identify from a 'traditional CPM' and from a resource perspective which activities are ‘critical’ and which ones are ‘not critical’. In a schedule that is NOT resource loaded (a 'traditional CPM'), activities are CRITICAL in case, if scheduled at their early start date and delayed, they would delay the overall project completion. A chain of activities that are critical is called the CRITICAL PATH, from there also the name “critical path scheduling” or CPM. Now consider a schedule that IS resource loaded. Resource critical extends the definition of critical. Activities are RESOURCE CRITICAL in case, if scheduled at their early start date and delayed, they would delay the overall project completion. This situation occurs when the number of available

If the scheduled completion date (without resource loading) gets extended because of resource limitations, then activities that were plain CRITICAL may no longer be critical, but others will be RESOURCE CRITICAL. Activity Select the best option: B Not critical but resource critical E [ Select ] G [ Select ] Not critical but resource critical Not critical and not resource critical Critical and resource critical 1.25 / 1.25 pts Question 4 Continuing with question 2.

Float (total float) when not considering resource loading Float (total float) when considering resource loading B 7 0 E
