Identification of potential bottlenecks in proposed process flow
Redesigning of process flow to alleviate bottlenecks
Client's Challenge
The body shop plans to introduce new model C while producing existing models A,B
Each body type requires its own special pallet type
the proposed empty pallet release process flow to: 1. Ensure pallets are released efficiently in production sequence while maintaing current production levels 2. Minimize empty pallet set-asides
PMI's Approach
Analysis of Data and Verification of Baseline Model
Identification of bottleneck by measuring pallet set asides in return loop section
Findings & Recommendation
Proposed process flow was ineffective because:
Facility has to manually “set-aside” excess B type pallets to alleviate blockage(see Fig. 1)
Revised the process flow in pallet return loop to minimize manual set-asides(see Fig. 2)
Cost effective solution - 25% savings in buffer space while maintaining current production
Revised process flow found to be able to handle up-to 20% variation in product mix(see Fig. 3)
