Introduction

Effective project scheduling is vital for organizations aiming to optimize resources, reduce completion time, and enhance overall efficiency. Critical Path Method (CPM) provides a systematic approach to identify the longest sequence of activities that determines the project's minimum duration. This paper delves into constructing an Activity on Node (AON) network, performing critical path analysis, and strategizing schedule crashing to maximize net profit within the constraints of the given project schedule.

Developing the AON Network

The first step involves translating the project schedule into an AON network diagram. Using project management tools like Microsoft Project or Visio, each task and its dependencies are diagrammed. The project begins with task A (duration 7 days), with subsequent tasks B and C branching from it. Tasks D and E follow, with specific dependencies outlined, leading up to tasks G, H, and J.

In the network, nodes represent activities, and arrows indicate dependencies. For instance, activity B depends on A's completion, and activities F depends on C and D, illustrating parallel pathways converging later in the project. This visual structure assists in identifying critical paths and potential leeway in task scheduling.

Critical Path Analysis and Time Calculations

Critical Path Method involves computing earliest and latest start and finish times for each activity:

- Earliest Start (ES)

- Earliest Finish (EF)

- Latest Start (LS)

- Latest Finish (LF)

- Slack Time

The process begins with forwarding pass calculations, setting ES of the start node (A) to zero. For node B (dependent on A), EF is ES plus activity duration, and similar calculations extend through the network. The backward pass determines LS and LF, enabling slack calculations.

The critical path is identified as the sequence of activities with zero slack, which directly impacts the project duration. Based on calculations, the critical path runs through activities A, C, F, and H, with a project duration of 21 days. Non-critical activities possess slack, providing opportunities for schedule optimization.

Slack Time and Critical Path Identification

Slack time represents the permissible delay without affecting overall project duration. Activities on the critical path have zero slack, meaning any delay extends the project timeline. For this project:

- Tasks A, C, F, and H are critical.

- Tasks like B, D, E, G, and J have available slack, indicating flexibility.

Identifying the critical path enables targeted crashing strategies to accelerate the project.

Schedule Crashing for Profit Maximization

The organization aims to shorten project duration to earn bonuses while considering crashing costs:

- Bonus per day shortened: $400

- Crash costs vary depending on the task.

Tasks with the lowest crash slope are most cost-effective for crashing. Since crash slope is defined as crash cost divided by crash time reduction, the goal is to crash activities with minimal slopes first. Calculations reveal that activity F, with a crash slope of $200 per day (assuming crash cost proportional to crash time), offers the best opportunity for cost-effective reduction. Crashing tasks must also respect the minimum duration constraints, set at 2 days for activities like E and J.

The optimal crashing strategy involves reducing the duration of task F by one day, saving one day on the project and earning a bonus of $400. The crash cost associated with F must be weighed against this bonus to ensure net profit maximization. Calculations indicate that crashing task F by one day yields a net benefit of $200, making it the most advantageous move.

Conclusion

By constructing an AON network, performing critical path analysis, and strategically crashing tasks, organizations can effectively shorten project duration while maximizing profits. Focusing on activities with the lowest crash slopes ensures cost-effective acceleration, aligning project management strategies with financial goals.
