Study Notes
Stock Optimisation
-
Definition: Stock optimisation involves managing inventory levels to reduce costs while meeting customer demand.
-
Objectives:
- Minimize holding costs (storage, insurance, spoilage).
- Avoid stockouts (lost sales or customer dissatisfaction).
- Improve cash flow and operational efficiency.
-
Key Concepts:
- Economic Order Quantity (EOQ): A formula used to determine the optimal order quantity that minimizes total inventory costs.
- Reorder Point (ROP): The inventory level at which a new order should be placed to replenish stock before running out.
- Safety Stock: Extra inventory kept to mitigate the risk of stockouts due to demand variability or supply chain disruptions.
-
Models of Stock Optimisation:
- ABC Analysis: Categorizes inventory into three classes (A, B, C) based on importance and value to focus management efforts on critical items.
- Just-In-Time (JIT): Inventory strategy that aligns raw-material orders with production schedules to reduce inventory costs.
- Vendor-Managed Inventory (VMI): Suppliers manage the inventory of their products in the customer’s warehouse to optimize stock levels.
-
Techniques:
- Forecasting: Use historical data and market trends to predict demand.
- Inventory Management Software: Tools that automate tracking and analysis of stock levels.
- Continuous Review System: Regularly monitoring inventory levels and placing orders as needed.
-
Challenges:
- Demand variability and unpredictability.
- Supply chain disruptions (e.g., delays, shortages).
- Balancing cost efficiency with service levels.
-
Performance Metrics:
- Inventory Turnover Ratio: Measures how often inventory is sold and replaced over a period.
- Service Level: Percentage of customer demand met without stockouts.
- Gross Margin Return on Investment (GMROI): Assesses the profitability of inventory.
-
Best Practices:
- Regularly review and adjust inventory policies.
- Collaborate with suppliers for better forecasting and stock management.
- Implement technology for real-time inventory tracking and analytics.
Stock Optimisation
-
Definition: Involves managing inventory levels to reduce costs while satisfying customer demand.
-
Objectives:
- Minimize holding costs such as storage, insurance, and spoilage.
- Prevent stockouts to avoid lost sales and customer dissatisfaction.
- Enhance cash flow and overall operational efficiency.
Key Concepts
-
Economic Order Quantity (EOQ): Formula for determining the optimal order quantity that minimizes total inventory costs.
-
Reorder Point (ROP): Inventory level at which a new order must be placed to avoid stock shortages.
-
Safety Stock: Additional inventory kept to protect against stockouts caused by demand fluctuations or supply chain issues.
Models of Stock Optimisation
-
ABC Analysis: Inventory categorization method that sorts items into three classes (A, B, C) based on their importance and value.
-
Just-In-Time (JIT): Strategy that synchronizes raw material orders with production schedules to decrease inventory expenses.
-
Vendor-Managed Inventory (VMI): Suppliers oversee and manage the stock of their products within the customer's warehouse to maintain optimal levels.
Techniques
-
Forecasting: Employs historical data and market trends to accurately predict future demand.
-
Inventory Management Software: Tools designed to automate the tracking and analysis of stock levels effectively.
-
Continuous Review System: Involves regular monitoring of inventory levels and timely ordering as necessary.
Challenges
-
Fluctuating and unpredictable demand can complicate inventory management.
-
Supply chain disruptions, including delays and shortages, can impact stock levels.
-
Balancing cost efficiency with maintaining high service levels presents ongoing challenges.
Performance Metrics
-
Inventory Turnover Ratio: Indicates how frequently inventory is sold and replaced in a specific time frame.
-
Service Level: Represents the percentage of customer demand met without experiencing stockouts.
-
Gross Margin Return on Investment (GMROI): Evaluates the profitability of the inventory held.
Best Practices
-
Conduct regular reviews and adjustments of inventory policies to align with business needs.
-
Collaborate with suppliers to enhance forecasting accuracy and stock management strategies.
-
Utilize technology for real-time inventory tracking and analytics to optimize decision-making.
