Schedulingfor An Organization The Following Project Schedule Is Given
Effective project scheduling is essential for organizations aiming to optimize resource allocation, reduce project duration, and maximize profit. This paper presents a detailed analysis of the given project schedule, including the construction of an Activity on Node (AON) network, critical path determination, slack time calculation, and an optimal crashing strategy to enhance project profitability. Using standard project management techniques, the analysis utilizes critical path method (CPM) principles to ensure precise planning and control, supporting the findings with relevant scholarly references.
Constructing the AON Network
The project schedule provided involves nine activities with respective predecessors, normal durations, and crash data. To begin, the AON network is constructed, representing activities as nodes and dependencies as directed edges. The activities are as follows:
- Task A: Predecessor None, Duration 7 days
- Task B: Predecessor A, Duration 3 days
- Task C: Predecessor A, Duration 4 days
- Task D: Predecessor A, Duration 4 days
- Task E: Predecessor B, Duration 2 days
- Task F: Predecessor C and D, Duration 2 days
- Task G: Predecessors E and F, Duration 6 days
- Task H: Predecessor F, Duration 4 days
- Task I: Predecessor G and H, Duration 4 days
- Task J: Predecessor I, Duration 2 days
Constructing this network using Microsoft Project or Visio involves creating nodes for each activity and drawing edges based on the dependency relationships. This visual network forms the basis for critical path analysis.
Critical Path Analysis: ES, EF, LS, and LF Calculation
The critical path method involves calculating the earliest start (ES), earliest finish (EF), latest start (LS), and latest finish (LF) times for each activity. The process begins with a forward pass to determine ES and EF, followed by a backward pass for LS and LF.
Forward pass:
- A: ES=0, EF=7 (ES+duration)
- B: ES=7 (EF of A), EF=10 (ES+3)
- C: ES=7, EF=11
- D: ES=7, EF=11
- E: ES=10, EF=12
- F: ES=11 (max EF of C and D), EF=13
- G: ES=12 (max EF of E and F), EF=18
- H: ES=11, EF=15
- I: ES=18 (max EF of G and H), EF=22
- J: ES=22, EF=24
Backward pass:
- J: LF=24, LS=22 (LF - duration)
- I: LF=22, LS=18 (min LS of successors)
- H: LF=18, LS=14
- G: LF=18, LS=12
- F: LF=15, LS=13
- E: LF=12, LS=10
- D: LF=11, LS=7
- C: LF=11, LS=7
- B: LF=10, LS=7
- A: LF=7, LS=0
From these calculations, the critical path comprises the activities with zero slack time, specifically activities A, B, E, G, I, and J, indicating the longest path and shortest project duration of 24 days.
Slack Time Calculation
Slack time for each activity is determined by subtracting ES from LS or EF from LF. Activities on the critical path inherently have zero slack, while others may have positive slack, indicating flexibility.
- A: Slack=LS-ES=0
- B: Slack=0
- C: Slack=LS-ES=0 (on non-critical path)
- D: Slack=LS-ES=0 (on non-critical path)
- E: Slack=0
- F: Slack=LS-ES=2 (not on critical path)
- G: Slack=0
- H: Slack=LS-ES=3
- I: Slack=0
- J: Slack=0
Some activities like F and H have positive slack, providing room for potential crashing to shorten the project duration.
Identifying the Critical Path
The critical path, being the longest path with zero slack, is composed of activities A → B → E → G → I → J, totaling 24 days. These activities directly impact the project's minimum duration.
Profit Optimization through Crashing
The organization can reduce project duration through crashing, with each day shortened earning a bonus of $400. However, crashing incurs additional costs, represented by crash costs in the data. To maximize profit, the optimal activity to crash and the extent of crashing must be determined, balancing bonus earnings against crash costs.
Activities eligible for crashing are those with positive slack or on the critical path. The crash slope (cost per day saved) guides decisions. For instance, studying the crash data, if activities like F and H can be crashed at reasonable costs, they become prime candidates.
Suppose crashing activity F by 1 day reduces the project by one day at a crash cost of, say, $100. Similarly, activity H might be crashed by 1 day at a cost of $150. The net profit would increase when the bonus earnings from reducing the project duration outweigh the crash costs.
In this case, crashing activities with the lowest crash costs per day saved on the critical path offers the best profit margin. Activities such as F and H, with lower crash slopes, are immediate candidates. The decision ultimately involves calculating total crash costs for various crash levels and comparing added bonus earnings. The optimal crash level maximizes net profit, considering the bonus for each day saved minus the crash costs.
Given that crash costs have not been specified explicitly for activities, we assume a uniform slope or estimate based on typical crash cost data. For this example, crashing F and H by one day each would deliver the highest net benefit, increasing project savings without disproportionately increasing crash costs.
Conclusion
This comprehensive analysis demonstrates that constructing an AON network, performing CPM calculations, and strategically crashing activities can significantly reduce project duration and enhance organizational profitability. The critical path identified guides focused crashing efforts, and an economic analysis ensures maximum net gain. Applying these project management principles enables organizations to optimize schedules effectively while controlling costs.
