Concept explainers
A.
Interpretation: The earliest and the latest starting and finishing times for all activities are to be determined and the days required to complete the project are to be calculated. Also, a Gantt chart need to be drawn indicating activity slack.
Concept Introduction: Network diagram is a graphical representation of tasks and events happening in a project. It depicts the work flow and is used to compute the total duration of the project.Gantt chart is a project management tool that is a type of bar chart. It depicts the project
B.
Interpretation:A feasible schedule for the project is to be determined assuming that none of the activities mentioned can be done simultaneously.
Concept Introduction: Gantt chart is a project management tool that is a type of bar chart. It depicts the project schedule and is used for resource allocation. Resource loading is a method of allocating manpower, equipment and materials required for completion of a project.
C.
Interpretation:The resource loading profiles for the consumable resources R1 and R2 used for the project are to be determined.
Concept Introduction: Resource loading is a method of allocating manpower, equipment and materials required for completion of a project.
D.
Interpretation:Thecumulative amount of resources consumed are to be determined if schedule determined in part (b) is used.
Concept Introduction: Resource loading is a method of allocating manpower, equipment and materials required for completion of a project.

A community neighborhood association decided to add a swimming pool to the community activity center. The project is divided into the activities listed in the following table. The activity times and costs, both normal and crashed, are given. To finish the project before the summer season starts, the neighborhood has to make time and cost tradeoffs. If the project needs to be finished in 20 weeks, you are required to formulate a linear programming model to decide about how much to crash for each activity.

This has been increasingly challenging for the company, so the Justin is looking to consolidate and integrate the financial management across all locations into a single software system that can operate across the national boundaries. This is a new, complicated and lengthy project, so Justin has identified a set of activity categories that will need to be carefully managed, as noted in the table.
