Ordering costs cover purchasing and receiving parts. Frequent small orders increase these costs. Bulk orders may reduce per-unit costs but tie up more capital.

Centralized storage can lower overall inventory costs. It improves accuracy and accessibility. This approach often reduces duplicate stock across locations.

Obsolescence is a major cost risk for spare parts. Slow-moving items may become outdated before use. Regular inventory turnover reviews help identify at-risk parts.

Spare Parts Inventory Strategies

Managing spare parts inventory requires careful planning and smart tactics. The right approach can save money and keep operations running smoothly. Three key strategies help businesses optimize their spare parts management.

Economic Order Quantity (EOQ)

EOQ helps find the ideal order size for spare parts. It balances ordering and holding costs to minimize total inventory costs.

To calculate EOQ, you need annual demand, ordering cost per order, and holding cost per unit per year. The formula is:

EOQ = √[(2 x Annual Demand x Ordering Cost) / Holding Cost]

Using EOQ can lead to big savings. It reduces excess stock and frequent orders. This method works well for parts with steady demand.

CMMS Systems can help track inventory and calculate EOQ, making it easier to keep the right amount of parts on hand.

Just-In-Time (JIT) Inventory

JIT aims to have parts arrive precisely when needed. This cuts storage costs and reduces waste. It works well for expensive parts or those with short shelf lives.

JIT requires close ties with suppliers. You need fast, reliable delivery. Good forecasting is also key. Without it, you risk running out of critical parts.

Detailed maintenance records help with JIT. They show patterns in part usage. This info helps predict when you’ll need new parts.

JIT can be risky. A single delay can halt production. But when done right, it greatly improves efficiency.

ABC Analysis for Inventory Control

ABC analysis groups spare parts by value and importance. It helps focus management efforts where they matter most.

• A items: These are high-value, critical-to-operations items. They get the most attention because they are for critical equipment. These items are well suited for JIT.
• B items: Moderate value and importance.
• C items: These are low-value and many in number. You can use simpler controls for these items and keep higher inventory counts due to the lower cost of the material.
