Course objectives: This course is intended to provide an introduction to the design, analysis and control of manufacturing systems. Systems of interest include automated flow lines, assembly systems, cellular and flexible manufacturing systems. Both hardware and software requirements of such systems will be reviewed. However, emphasis will be on methodologies of system design, modeling and control. Issues addressed will include part flow management, lead time analysis, facilities planning and layout, real time production control and scheduling, and information flow management. Special attention will be paid to emerging trends in manufacturing such as JIT, agile manufacturing, theory of constraints, computer integration, and distributed manufacturing.

Prerequisites: Although not required, introductory courses in operations research, production planning and control, and manufacturing processes are useful.

Instructor: Prof. Saifallah Benjaafar - ME 205 - Tel: 6-7239 - email: saif@staff.tc.umn.edu

Office hours: Wednesday: 2:00 - 1:00 and Friday 2:00 - 4:00 (or by appointment).

Teaching assistant: Mehdi Sheikhzadeh, ME 15B, email: mehdi@me.umn.edu.

Homework: Assigned weekly and is due a week from the assignment date (unless instructed otherwise). Homework solutions will be either distributed in class or placed on reserve in Walter Library. In addition, each student will be assigned a paper for in-class presentation and critique. All students are required to provide a one page summary of each presented paper. Summaries are due the day of the corresponding presentation.

Exams: Two in-class exams. Tentative dates are: October 29 and November 26. No final exam. Exam solutions and sample exams will be either placed on reserve in Walter Library or distributed in class.

Term Project: Two progress reports will be due October 15 and November 5, respectively. Project presentations will be scheduled during the last week of class. Project reports will be due on the last day of finals week.

Grading: Final grades will be assigned based on the following breakdown:

Exam 1: 25%, Exam 2: 25%, HWK: 25%, and Project: 25%.

Computer access: Access to the following computing laboratory is provided: ME 308 (IBM & SGI), EE/CS 3-166 (MAC & IBM), and EE/CS 4-204 (Mac, Sun & Next). Lab attendants should be able to help you with workstation access and operating systems problems. Graduate students have also acccess to the CIMLAB in Old EE 248.

Re-grades: You may submit an assignment or an exam for a re-grade within 5 working days following its return date. Re-grade requests are not accepted after this time limit. The requests must be accompanied by a written explanation of where you feel the original grading was inaccurate.

Incompletes: The grade of "I" is awarded only in the case of exceptional and verifiable severe illness or tragedy. An "I" will not be awarded because you are doing poorly in the class.

Class attendance: While attendance will not be taken, attendance of all lectures is expected. You will be held responsible for all material presented and work assigned in class. Copies of notes for any missed lectures will not be provided.
