Unpaced Lines

Unpaced Lines

  • Introduction
    The main objective of this module is to give an introduction to unpaced lines. This module is mainly focused on the effects of random breakdowns and the curative power of the buffers. Also expressions for throughput in longer lines are discussed for both random processing times and random workstation failures. The module is intended for use as a regular lecture in a graduate introductory course to Manufacturing Systems Analysis, or a self-contained support lecture in a graduate course that focuses on modeling and analysis of manufacturing systems. The background knowledge required for the module is elementary knowledge of assembly lines and serial systems. In particular, it will be helpful if the student has some knowledge in probability and statistics. The module is designed to make the students active participants in the lecture's exercises. This is made possible by the use of Active Learning techniques. The module design is tailored for a class that has been divided into teams. The ideal size of the teams is three or four students. However, smaller or larger teams can also be accommodated without any changes to the module's structure.
