Question

The following table shows activities with duration, dependency, dependency type, and the number of workers from one small segment of a project network. Draw the segment of the network diagram and then: (a) Show the resource usage (chart) if activities A, B, and C start on day one; (b) Show the new network diagram and the resource usage (chart) when resources are leveled after applying appropriate slack times.

 

 

This table outlines the details of various activities within a project. Each activity is characterized by its duration, predecessors, dependency type, and the number of workers involved. Here's a detailed explanation: | Activity | Duration | Predecessor (dependency) | Dependency Type | Number of Workers | |----------|----------|--------------------------|-----------------|-------------------| | A | 2 | - | D | 2 | | B | 4 | - | D | 2 | | C | 10 | - | M | 4 | | D | 3 | A | D | 2 | | E | 1 | B | D | 2 | | F | 2 | C,D,E | M(C,E) | 4 | ### Explanation: - **Activity**: This column lists the various tasks or activities in the project. - **Duration**: The time each activity is expected to take. For example, Activity A has a duration of 2 units of time. - **Predecessor (dependency)**: This shows which activities need to be completed before the current activity can begin. A dash ("-") indicates no predecessors. - **Dependency Type**: - "D" indicates a Direct dependency, where one activity depends on the completion of another. - "M" indicates a Multiple dependency, where the activity may depend on more complex conditions or multiple predecessor activities. - "M(C,E)" for Activity F signifies a dependency on the completion of Activities C and E. - **Number of Workers**: Indicates how many workers are assigned to each activity. For example, Activity C involves 4 workers. This table is used for project planning and scheduling, helping to allocate resources efficiently and identify dependencies between tasks.
