IEMS 307: Quality Improvement by Experimental Design

Quarter Offered

Spring : TTH 9:30-10:50 ; Ankenman

Prerequisites

IEMS 201 or IEMS 303 or equivalent

Description

Methods for designing and analyzing industrial experiments.  Blocking; randomization; multiple regression; factorial and fractional factorial experiments; response surface methodology; Taguchi’s robust design; split plot experimentation. Homework, labs, exams, and a project.

  • This course is a major requirement for MaDE and an IE/OR Technical Elective for IEMS

LEARNING OBJECTIVES

  • Students will be able to design, conduct, and analyze comparison experiments and make engineering decisions based on the results.
  • Students will be able to design, conduct, and analyze factorial and fractional factorial experiments and make engineering decisions that account for estimation uncertainty and confounding of main effects and various interaction effects.
  • Students will be able to follow a process of experimental optimization to optimize a design or the settings of a process.
  • Students will be able to design and analyze experiments that have multiple levels of variability.
