Greenfield Facility - Throughput Validation and Improvement
Key Points
Batch type production - 14 Product Types
Impact of Product Mix on system throughput
Buffer sensitivity analysis
Client's Challenge
14 Product types with different foundry flow and product-dependent cycle time made it difficult to calculate the system's throughput
Equipment Utilization was highly dependent on Product Mix
Batch size of a product family - Different across the process flow
With all the above variations, predicting the required buffer capacities
PMI's Approach
Data analysis, 3D model building, verification & validation
Throughput improvement carried out by analysis of product mix
Sensitivity Analysis carried out on buffer capacity
The throughput Improvement Roadmap was built to meet the expected demand
Sensitivity Analysis also carried out on buffer capacity for expected demand
Findings & Recommendation
The facility was unable to meet the target throughput
Throughput showed strong dependence on Product Mix
With the current setup, max. system throughput was validated to be 18% less than expected
The number of resources required to satisfy expected demand was calculated
Required buffer capacities around the facility were suggested
The average lead time was indicated
