ENGR 1181 Lab2: Quality and Productivity Lab Lab Procedure 1. Overview of Quality and Productivity Lab The Quality and Productivity lab introduces various aspects of the manufacturing process. At the end of this laboratory experience, it is expected that the students understand the core, fundamental principles of Lean and Sigma manufacturing as well as understand the difference between a push and pull system. Learning Objectives – students will be able to: 1. Gain an appreciation for the importance of engineering in manufacturing processes. Industrial Systems Engineering encompasses the design, analysis, and evaluation of the whole manufacturing process. 2. Enhance productivity, speed, quality, cost and sustainability in the manufacturing process via the core, fundamental principles of Lean production (eliminating waste) and Six Sigma (reducing variation in the product). 3. Understand the fundamental difference between PUSH and PULL systems on the assembly line. 2. Manufacturing Processes Products are manufactured in a variety of different ways following many unique and different processes. Fixed Manufacturing Process Here the product does not move and remains in a fixed position throughout the manufacturing process, as portrayed in Figure 1. This type of manufacturing process is typical of large cumbersome items such as a home or office building. Figure 1: Fixed Manufacturing Process

ENGR 1181 Lab2: Quality and Productivity Lab Lab Procedure Custom Product Manufacturing Process This process is typical of products where inputs from the customer (and outcomes from other processes) are used to modify the product during the manufacturing process. Products manufactured through this process are usually of low volume, such as custom software, as portrayed in Figure 2. Figure 2: Custom Product Manufacturing Process Batch Manufacturing Process In this manufacturing process, the final product is made in a series of independent and disconnected stages. It has the advantage of being capable of producing several products in a single production line. A simple example of the Batch manufacturing process is listed below. 1. Collect your dirty washing as two loads. 2. Put the first load into the washing machine. 3. When washed, dry the first load in the drier and place the second load into the washer. 4. When the first load is dry, place the second load into the drier and begin ironing and folding the first load. 5. Iron and fold the second load when it has been dried. Sequential Manufacturing Process In this process the product is moved sequentially along an assembly line. There are two typical sub-types of this manufacturing process, the push system and the pull system : Push System In a push system, assumptions regarding demand are made to simplify the overall process.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
