Lean Manufacturing

In this activity, students will explore how lean manufacturing can apply to the assembly process in a simulated airplane assembly plant.

Students will identify the process wastes and provide solutions to improve. Through multiple iterations, students will collect data about the number of planes produced and if they met customer demand as well as production time and amount of work in progress items.

Activity Components

Pre-Laboratory Engagement

Students can begin to think about time wastes and how organization decreases that waste with a 5S activity.

Activity

In this activity, students will have the opportunity to see assembly line processes in live time and see hands-on how small changes to the process can vastly improve production.

This activity can be used to present advanced manufacturing concepts or to introduce the concept of change as a positive force. Throughout the activity, students will compare cellular manufacturing, pull/push systems, batch size, work in progress as a manageable asset, inventory risks, independent cross training, and the effects of rapid throughput with traditional manufacturing.

This activity dramatically demonstrates the advantages of advanced production techniques over traditional production methods still practiced by many companies today. The activity consists of four different phases. By working through the four basic phases, students quickly understand the dynamics necessary to maximize throughput, minimize losses, and minimize inventory.

Utilizing a hands-on approach, students operate workstations (WS) along the assembly line in a fictional aircraft plant. For simplicity, the actual construction materials and components are represented with Lego blocks. Labor skills, deadlines, quality control and other real-life situations have been incorporated into each phase of the simulation. Each phase of the simulation runs approximately 6 minutes.

Post-Laboratory Extension

Students can further explore lean and how to best solve problems related to bottlenecks with another simulated manufacturing experience.
