Even if you perfectly solve a problem with a very nice report and presentation, if the problem is simple very similar to the in-course problems or standard problems provided in the other textbooks, then you will get a low grade. Even if you perfectly solve a very difficult problem, if you cannot explain the process in your report and presentation, it would be valueless in a real life business (as you will not be able to sell it), hence you will get a low grade. So select a nice problem and prepare a good report & presentation. Important deadlines for your project are: -Forming groups: 23.10.2024 (Students who is not assigned to a group will be randomly assigned to any group. Groups will not change after this date.) -Submission of the report: 27.11.2024 The final examination will be an open-book written exam with essay questions/problems. In addition to classical problems, you will also be asked to fill in forms representing Excel spreadsheets. Please bring your calculators and necessary stationary equipment with you for the exam. Sharing calculators or any stationary equipment will not be allowed. Class Policy: Students are obliged to maintain the learning environment. When asked, students are expected to participate in in-class activities. Lack of knowledge of the rules is not a reasonable explanation for a violation. Any violation of the rules or causing a disturbance in the classroom will be observed and necessary actions will be taken.

In a 2070 DOD will be added by the in-class activity score. The midterm score will be calculated based on a group project. Groups may involve exactly 4 students. Students may form their own groups before the due date on the think provided in the moodle system. Students who did not attend to a group will page 1 of 4 Operations Research II Dr. Mustafa Çimen be randomly assigned to a group on the due date. Any changes after the due date will not be allowed, except for extraordinary excuses. -The project is on defining and solving a decision problem. You will find a real-life decision problem, define it and work on it. -The decision problem should be well-defined, realistic and worth to work on. The decision problem may be found from any source, including newspapers, TV news, a movie or your imagination, and not obliged to be industrial. However, the effort you pay to solve the problem should have a sufficient remuneration in real life (assuming that your solution is applied, of course). -Once you spot a problem, the instructor will assist you for officially defining and formulating the problem. If the problem is too large to solve, simplifications/assumptions can be made if allowed by the instructor. - You can use any solution approach taught in the course (Integer Programming and/or Goal Programming approaches). Then, you are expected to solve the problem using Excel Solver. - You will be required to write a report (50%) and make a presentation (60%). -The report should be around 3-6 thousand words (not a condition but a clue), will be in the form of a clear and detailed business report and should consist of the definition of and solution to the decision problem: * Introduction: Context of the problem. Where did you find it? Motivation: Why is this an important problem? * Problem definition: What do you need to decide, what is your aim, what limits you within the problem context. Mathematical model: Decision model of the problem, with explanations (i.e., explain each expression in the objective function, how each constraint works, etc..) Solution: Screen shots of the Excel-Solver windows you used, and presentation of results in detail. * Conclusion: A summary of what you did and how your results fit in the real-life problem. * Appendix: A shortened version of your report, which involves a small-sized version of your decision problem. The problem should involve the same types of constraints and objective function expressions, but with a smaller number of variables and constraints. One of your final exam questions will be based on one of these summaries. -Reports will be submitted as printed hard copies in the classroom. Reports will be taken as two- sided, black&white (if color printing is not necessary) prints, stapled from top-left or top-right corner. No fancy stationary will be graded. - Late submission of the reports will be penalized by 10 points out of 100. If the submission is late for more than one week, each week passed will be penalized by extra 10 points. Submission of a single member of each group is sufficient. -The presentations will take place at the end of the semester. The orders of the presentation will be random. Each week, in the class, 7 groups will be randomly selected by Excel software among those who submitted their reports and presentation material (e.g., .ppt files) and have not yet presented their work. Hence all students are expected to be ready to present their material starting from the first presentation week. Remember that one of the final exam questions will be prepared based on one of these projects, hence understanding each project problem and solution is important for all students. -The presentation duration should be 15 minutes + 5 minutes question & answers. -As the presenting groups will be random, the presenting order of the students within each group will be also randomly selected by the instructor in order to ensure that each student should have a full understanding on not only a fraction of but the whole project. page 2 of 4
