Please help me to solve this question using 1)Decision Variable 2)Objective Function 3)ConstraintsYou have been asked to determine how long a project will take to be completed. This projectconsists of 11 tasks of varying time durations (measured in days) that must all be completed.Unfortunately, not all tasks can be done at the same time (although some can be done in parallel);certain predecessor tasks must be completed before others can be started. The table below givesthe duration and predecessors for each task. Thus, for example, task J cannot begin before each oftasks F, G, and H are completed.

You are managing a software development project. Only 35% of the work has so far been completed, while the planned schedule called for 50% completion by this date. Originally budgeted for $250,000, the team has already spent $150,000 on the project. What is the best way to describe the state of this project? Ahead of schedule, within budget Behind schedule, within budget Ahead of schedule, over budget Behind schedule, over budget
A project has 92 activities, but only 13 of them are analyzed here.

Consider the precedence network diagram. The numbers above the nodes represent activity durations (in days). End 13 Suppose that after 12 days, activities 1, 9, and 2 have been finished; activity 3 is 75 percent finished; and activity 10 is half finished. How many days after the original start time would the project finish? The project should finish ]days from the start.
We reduce Activity B to 4 weeks on each of the six houses.What affect will that have on the project completion time? Show work on the template provided. The x axis is the number of houses The y axis is time (number of weeks)
Consider a project with four activities. Activities A1, A2, and A3 all can start immediately.However, A4 requires the completion of A1, A2, and A3. A1 can take any time between4 and 8 days. A2 can take any time between 2 and 6 days. A3 always takes 5 days. Inaddition to A4, which activity (or activities) has the potential to be on the critical path?a. A1b. A1 and A2c. A2 and A3d. A1, A2, and A3e. None of these options is correct
What is the least expensive method of halting some tasks in order to keep the project's (estimated) duration within the set range ?
To help with preparations, a couple has devised a project network to describe the activities that must be completed by their wedding date. A project network with 10 activities and 13 directed arcs is shown. Activity Start is connected to activity A and to activity B. Activity A is connected to activity C and to activity D. Activity B is connected to activity E. Activity C is connected to activity H. Activity D is connected to activity F and to activity G. Activity E is connected to activity F and to activity G. Activity F is connected to activity H. Activity G is connected to activity Finish. Activity H is connected to activity Finish. Activity Finish has no arcs directed to other activities. The following table lists the activity time estimates (in weeks) for each activity.

3. Compute the early, late, and slack times for the activities in the network that follows, assuming a time-constrained network. Which activities are critical? What is the time-constrained project duration? Note: Recall, in the schedule resource load chart the time-consmael scheduling interval (ES through LF) has been shaded. Any resource scheduled beyond the shaded area will delay the project. Assume you have only three resources and you, are using a computer that uses software that schedules projects by the parallel method and following heuristics. Schedule only one period at a time! Minimum slack Smallest duration Lowest identification number 282 Chapter 8 Scheduling Resources and Costs Keep a log of each activity change and update you make each period-e.g., period 0-1, 1-2, 2-3, etc. (Use a format similar to the one on page 259.) The log should include any changes or updates in ES and slack times each period, activities scheduled, and activities delayed. (Hint: Remember to maintain…
12. In general, work packages should not exceed 10 work days. 13. The project structure chosen to manage the project will have little impact on the actual project work to be accomplished. 14. An activity is an element of the project that always requires time but may or may not require resources. 15. The forward pass through a project network determines the critical path. 16. Different activities along the same path can have different total slack. 17. It is possible to have more than one critical path at the same time. 18. Free slack applies to an entire project network. 19. Lags are used to break larger activities into smaller segments so that activities that follow can be started earlier. 20. In a balanced matrix form of project management, the project manager is responsible for defining what needs to be accomplished while the functional managers are concerned with how it will be accomplished.
