Choose the correct answer from the options given below:

The correct answer is A - IV, B - III, C - I, D - II.

Key Points

The correct sequence is:

A. Crashing an activity - IV. Taking special (costly) measures to reduce the duration of an activity below its normal value
Crashing an activity refers to the process of shortening the duration of an activity in a project. It involves taking special measures, which can be costly, to expedite the completion of the activity. These measures may include adding more resources, working overtime, or using specialized equipment to accelerate the work. Crashing an activity allows for a shorter overall project duration but often comes with additional costs.

B. Project Network - III. It consists of a number of nodes and a number of arcs that connect two different nodes
A project network is a graphical representation of the activities and their dependencies within a project. It consists of nodes, which represent the activities, and arcs, which connect the nodes to show the logical sequence and dependencies between the activities. The project network helps visualize the flow of work and the relationships among activities, aiding in project planning, scheduling, and monitoring.

C. Critical path - I. Length of the longest path through the project network
The critical path in a project network is the longest path from the project's start to its end. It determines the minimum amount of time required to complete the project. Any delay in activities along the critical path will directly impact the overall project timeline. Identifying the critical path is essential for project scheduling and resource allocation, as it helps in prioritizing activities that are critical for the project's timely completion.

D. Crash point - II. It shows the time and cost when the activity is fully crashed
The crash point represents the time and cost associated with fully crashing an activity in a project. Fully crashing an activity means reducing its duration to the shortest possible time by applying all available resources and measures. The crash point helps in evaluating the impact of crashing activities on project timelines and costs. It provides insights into the trade-offs between time and cost when accelerating specific activities in a project.

Hence, the correct answer is A - IV, B - III, C - I, D - II.
