Optimize WIP inventory levels to reduce storage and holding costs without affecting production capacity. The report should recommend WIP inventory levels based on a balance between production requirements and cost minimization, incorporating historical inventory turnover rates and expected future demand. Use [InventoryTurnoverRate], [HoldingCosts], [ProductionSchedule], and [ExpectedDemand] as placeholders. The output should include recommendations on adjusting WIP levels, with potential cost savings and impact on production efficiency.
