This project focused on the modeling assignments and production planning for the medium wheel loaders for Caterpillar. The purpose behind this project was to study and evaluate in detail the possible modeling combinations to optimize the current resources on the medium wheel loaders in the robotic welding cell. Through time studies, changes in the modeling assignments, and a study of the flow of material through the robotic welders, several alternatives were determined. The project team used three deciding factors: robot utilization, labor utilization, and annual cost savings. Alternative one had the smallest decrease in robot utilization, the highest labor utilization under 85%, and the largest annual cost savings. Thus, the modeling assignment changes as well as the preparatory station changes resulting from alternative 1 are what the project team recommends for implementation.
