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.

Joe and Noël have just gotten engaged. Seeing as they are both business students, they thought that they’d try to plan out their wedding preparation as a project. Here’s the WBS they’ve determined is necessary for a simple but elegant wedding. Assume all durations are deterministic. Although perhaps not realistic to real wedding planning, use the standard calendar in ProjectLibre (use default working days in software). Based on the project you created, answer the following questions. Please note that each question is independent and not built upon each other. a) If Joe and Noël start wedding planning on January 1, 2023, when is the wedding day? b) What is the critical path? List all critical tasks in chronological order. c) Will the critical path change if Noël decides she needs two extra weeks for the Bridal Diet? If yes, what is the new critical path and when should the wedding be held? d) Assume that band auditions take twice as long as expected. Does this affect the…
You are in charge of a project at the local community center. The center needs to remodel one ofthe rooms in time for the start of a new program. Delays in the project mean that the center mustrent other space at a nearby church at additional cost. Time and cost data for your project arecontained in below table. Your interest is in minimizing the cost of the project to the communitycenter.Using the normal times for each activity, what is the earliest date you can complete the project?Suppose the variable overhead costs are $50 per day for your project. Also, suppose that thecenter must pay $40 per day for a temporary room on day 15 or beyond. Find the minimum-costproject schedule using below format.The AON diagram for the community center project is below. Crash 4 times and find total cost.
IS Development Assignment Notes Assume that you are in charge of IS for a mid-sized oil and natural gas company. The CEO is interested in developing an application that will give him information about the amount of natural gas passing through pumping stations located around North America. He wants it to work on his desktop, iPad, and smartphone. The features he wants on the application change every time you speak with him and you’re still in the planning phase. Now he’s asked for a schedule. How do you respond?
The SDLC is an established methodology which aims to manage the complexity of large softwareprojects by following a structured set of steps that all stakeholders need to adhere to. Projectteams following this methodology would conclude each step before moving onto the next stepwhich gives rise to the name waterfall methodology as steps are followed in sequence and movingback is not possible, much like water following down a waterfall (Bourgeois et al., 2019). D escribe the following steps in the system development life cycle (SDLC) Q.2.1 Preliminary analysis Q.2.2 System analysis Q.2.3 System design
Dave is the project manager for a construction project that is building agazebo. When the project first started, he met with the stakeholders to definethe scope.

True / False Questions Good project management is especially important with virtual teams. One way that project management differs from management of more traditional activities is because of the limited life-time of projects. Once a project is approved and underway, project managers are only responsible for effectively managing time and costs which, if done well, will assure project completion on time and on budget. Matrix organizations transfer control of workers to project managers for the duration of the project. Some organizations use a matrix organization to integrate the activities of specialists within a functional framework. The computing algorithm requires both a forward and backward pass. 7. A hierarchical (vertical) listing of what must be done during a project is called matrix. 8. An advantage of Gantt charts in project management is that they identify which activities can be delayed without delaying the overall project. 9. A Gantt chart is built using…

Please provide feedback and reaction to discussion below. A project is a “temporary activity launched for a specific purpose, to carry out a particular objective” (Wallace, 2020, p. 354). Projects are generally special and specific to a certain task. They also can contain many complicated or long-term steps that are needed to complete the project. In a project, steps and tasks are not always straight to the point. Because projects are unique, there are constraints to be followed. These constraints are forces that consists of time consumption, costs and budgets, and scope (Wallace, 2020). These forces work hand in hand and affect each other differently. A process is different from a project and generally less complicated. While projects contain complicated and elongated steps, processes are usually shorter and straight to the point. A process “is a series of events designed to deliver a product or service that is repeated over and over” (Wallace, 2020, p. 354). In order to keep the…
