In this discussion forum: Identify and explain at least five (5) project constraints, and explain the working of the triple constraint model of project management.Two law students, John and Marsha, are planning an all-nighter to prepare for theirlaw boards the following day.

Determine the exact timesthat each will begin and end studying each subject in order to minimize the totaltime required for both to complete studying all five subjects
- Solve the following problems using Excel Solver or R Studio. 1. Scott and Associates is an accounting firm that has three new clients. Project leaders will be assigned to the three clients. Based on the different backgrounds and experiences of the leaders, the various leader-client assignments differ in terms of projected completion times. The possible assignments and estimated completion times in days are given below. Find the optimal assignment of leaders to clients. 2. Suppose in problem 1, an additional employee, Joanne, is available for possible assignment, and that Joanne will take 14, 18and 36 days with clients 1, 2, and 3, respectively. What is now the optimal assignment of project leaders to clients?The Lotus Point Condo Project will contain both homes and apartments. The site can accommodate up to 10,000 dwelling units. The project must contain a recreation project: either a swimming-tennis complex or a sailboat marina, but not both. If a marina is built, then the number of homes in the project must be at least triple the number of apartments in the project. A marina will cost $1.2 million, and a swimming-tennis complex will cost $2.8 million. The developers believe that each apartment will yield revenues with a net present value of $48,000, and each home will yield revenues with a net present value of $46,000. Each home (or apartment) costs $40,000 to build. Formulate an integer program to help Lotus Point maximize profits.A project that you are managing is into six months of its accomplishment andthe planned duration is also six months. You are now reviewing the projectstatus. The actual cost of Activity A and B are RM 200,000 and RM 100,000respectively. The planned value for Activity A and B are RM 180,000 and RM80,000 respectively. The Activity A is 100% complete whereas Activity B isonly 75% complete. (a) Formulate the problem to determine whether the project is on-time and on-budget after six months using the Earned Value Analysis (EVA) method. (b) Generate the expected “cost at complete” and “time at complete” to finishthe project at this pace. (c) Present two initiatives to be undertaken by the project manager to improvethe situation based on Q4(b).
- A Construction Project A maintenance building construction project also includes an external electrical generator and water tank. The first activity is to excavate which requires two weeks. Following excavation, the maintenance building will be built, and then both the generator and the water tank can be installed. These three activities, building, generator, and tank, require six, four, and two weeks, respectively. Once this set of three activities is completed, the tank and generator can be connected to the building, an activity that requires five weeks. After the maintenance building is built, maintenance equipment can also be installed inside the building and this activity takes four weeks. Painting the maintenance building is also required, following its construction, and this takes three weeks. Finally, after the maintenance equipment is installed and the connection is completed, it will take two weeks to inspect the new maintenance facility.

- Brenda Last, an undergraduate business major at State University, is attempting to determine her course schedule for the fall semester. She is considering seven 3-credit-hour courses, which are shown in the following table. Also included are the average number of hours she expects to have to devote to each course each week (based on information from other students) and her minimum expected grade in each course, based on an analysis of the grading records of the teachers in each course: Course Average Hours per Week Minimum Grade Management I 5 B Principles of Accounting 10 C Corporate Finance 8 C Quantitative Methods 12 D Marketing Management 7 C Java Programming 10 D English Literature 8 B An A in a course earns 4 quality credits per hour, a B earns 3 quality credits, a C earns 2 quality credits, a D earns 1 quality credit, and an F earns no quality credits per hour. Brenda wants to select a schedule that…A student in the project management course takes no less than 20 minutes to solve a typical network problem and sometime, as much as 50 minutes. However, the most frequent time taken usually by students is 30 minutes for the same network. If one has to solve using PERT, then calculate the (i) expected time and variance to solve the network (ii) maximum and minimum allocated time to solve the networkEvery project is constrained in different ways.These limitations are often denoted as the “triple constraints”. Using an appropriate diagram, describe these constraints.
