M&L 781: Analysis & Design of Logistics Systems - Winter ’12 The Professor: John Saldanha 524 Fisher Hall Phone: 247-8003 saldanha_8@fisher.osu.edu (please put “781” in the Subject line) The Classes: Classes will be held on Mondays and Wednesdays from 9:30-11:18 AM SB 315. Office Hours: T, R 1:30 – 03:00 PM 524 Fisher Hall The Course: 781 can be described as a modeling course in logistics. We will cover a variety of logistics issues and discuss modeling approaches for solving them. The course is organized into four application modules (Forecasting, Routing & Scheduling, Facility Location, and Network Design) and one methods module (Modeling). Each application module will consist of a series of lectures on modeling and solution approaches to a class of problems, followed by a special lecture on case-studies and/or implementation issues. By the end of the course, you will: ! be familiar with several modeling problems commonly faced in logistics, ! understand the uses of, and the appropriateness of solving problems with, heuristics, optimization and simulation, ! be able to solve many of these problems using efficient heuristics (i.e. methods for finding good solutions to a problem) or optimization techniques (i.e. methods for finding the best solution), ! understand how companies address these problems in the “real world.” Readings and Texts: There is no course packet or text book for this course. There is no single textbook dedicated to the material we cover. All required readings for the in-class discussion are available on-line through the course web-site on Carmen or through Business Source Premier (see the reading list). The Grade: The final grade will be determined by the weighted average of the following: 35% Exam 1 40% Exam 2 25% Network Modeling Case The following is the grade distributions: A A- B+ B B- C+ C C- D+ D E [90, 100] [86, 90) [83, 86) [79, 83) [76, 79) [69, 76) [66, 69) [64, 66) [62, 64) [60, 62) [0,60) !90 86-89.9 83-85.9 79-82.9 76-78.9 69-75.9 66-68.9 64-65.9 62-63.9 60-61.9 <60 Homework: There will be 6 homework assignments assigned during the quarter. Homework, will not be graded but is an essential part of the learning by reinforcing through practice the concepts and problem solving methods taught in the classroom lectures. Hence, you are strongly encouraged to do the homework and then correct your solutions using the solution notes and videos posted on the due dates marked on the schedule on page 4 of this syllabus. 1 Extra Credit: Logistics Outside the Classroom (LOC): 5% extra credit can be obtained based on learning about logistics outside the classroom. There are a few different ways to obtain extra credit: 1. Logistics in the News. You can write a one page review of a logistics-related news item. This can come from a current newspaper, or logistics trade magazine. Please do not submit writeups of web-articles or company web-sites. If you use a web article or a web-site as your source you will receive an automatic zero (see LOC tips below). Each write-up is worth 1%. 2. Article Presentation: You can also present the topic to the class (a 3-5 minute interpretive review) and receive an additional 1%. A particular article, however, can only be presented by one student. 3. TLA Meetings. The Transportation and Logistics Association (TLA) meets at 7:30 pm on Tuesdays. You will receive 1% each time you attend a meeting featuring a visiting speaker and then submit a one-page write-up on what you learned from the talk. Submitting a writeup for a meeting you did not attend will be treated as academic misconduct so make sure you sign the meeting attendance sheet. NOTE: Attending a social meeting does not qualify, there has to be an invited speaker at the meeting making a presentation on logistics. TIPS about write-ups. Use the LOC document template from the Carmen course web-site. Type at least a full page (double-space) using 1 inch margins (I give partial credit for write-ups that are not a full page. Writing more than a page is fine). Use the reference style in the document footer. Incorrectly cited articles will be given partial credit. You may access electronic full-text articles of news papers and trade journals through Business Source Complete (see instructions at the bottom of page 5). Write about logistics issues and draw your own conclusions on how events affect logistics. Don’t tell me about announcements that were made at meetings, or what kind of pizza you had. Since I don’t want to be inundated with a flood of LOCs at the end of the quarter (five times the number of students in class) I have put due dates for the extra credit. For example, after Jan 10 you can only submit 4 LOCs, after Jan 19 you can only submit 3 LOCs and so on. LOC SHOULD BE TURNED IN BEFORE THE END OF CLASS ON THE DUE DATE *** *** Exams: LATE LOC WILL NOT BE ACCEPTED *** NO LOC WILL BE ACCEPTED BY E-MAIL *** All exams will be closed-book and closed-notes. The exams are not cumulative although some materials will carry-over. Should you be sick on an exam day, you must contact the professor more than 8 hours before the exam and schedule a make-up exam that must be taken within 2 days. You will also need to provide a doctor’s note. I take academic misconduct very seriously – see university policies attached below. Never represent someone else’s work as your own. If I suspect any violation of the Code of Student Conduct, I will bring it to the attention of the Committee on Academic Misconduct who will determine and impose an appropriate sanction. This can range from a formal reprimand to dismissal. Trust me, I’m good at catching misconduct and cheating isn’t worth the risk. 2 ACADEMIC INTEGRITY (ACADEMIC MISCONDUCT) Academic integrity is essential to maintaining an environment that fosters excellence in teaching, research, and other educational and scholarly activities. Thus, The Ohio State University and the Committee on Academic Misconduct (COAM) expect that all students have read and understand the University’s Code of Student Conduct, and that all students will complete all academic and scholarly assignments with fairness and honesty. Students must recognize that failure to follow the rules and guidelines established in the University’s Code of Student Conduct and this syllabus may constitute “Academic Misconduct.” The Ohio State University’s Code of Student Conduct (Section 3335-23-04) defines academic misconduct as: “Any activity that tends to compromise the academic integrity of the University, or subvert the educational process.” Examples of academic misconduct include (but are not limited to) plagiarism, collusion (unauthorized collaboration), copying the work of another student, and possession of unauthorized materials during an examination. Ignorance of the University’s Code of Student Conduct is never considered an “excuse” for academic misconduct, so I recommend that you review the Code of Student Conduct and, specifically, the sections dealing with academic misconduct. If I suspect that a student has committed academic misconduct in this course, I am obligated by University Rules to report my suspicions to the Committee on Academic Misconduct. If COAM determines that you have violated the University’s Code of Student Conduct (i.e., committed academic misconduct), the sanctions for the misconduct could include a failing grade in this course and suspension or dismissal from the University. If you have any questions about the above policy or what constitutes academic misconduct in this course, please contact me.
