This document proposes a new flexible storage method called FP2C (Flexible Place/Constant Bin/Constant Qty) to address constraints with the existing 3C (Constant Place/Constant Bin/Constant Qty) storage method. FP2C allows parts to be stored in flexible locations while keeping bins and quantities constant. This saves around 50% of storage space and costs while improving FIFO, traceability, inventory monitoring and reducing part damages compared to the fixed 3C method. FP2C is suitable for raw material, finished goods, work-in-process, compound and warehouse storage. The document includes examples to illustrate the FP2C method and compares it to the existing 3C approach.
