Changing the narrative to drive analytically-charged innovation in supply chain management
Optimising Inventory Using Machine Learning
A Deep Dive into Advanced Techniques
Effective inventory management is essential for businesses of all sizes, spanning from online retail behemoths to industrial manufacturing facilities. The ability to efficiently manage inventory can result in cost reductions, enhanced customer experiences, and smoother operational processes. Yet, traditional inventory management approaches frequently struggle to keep pace with the intricacies of contemporary supply chains. Enter machine learning (ML), revolutionising inventory management with advanced solutions that address modern challenges like never before.
Challenges and Perspectives for Inventory Optimisation
Understanding Inventory Optimisation
Inventory optimisation entails strategically managing stock levels to align with customer demand, all while minimising expenses and maximising operational efficiency.
This multifaceted process includes forecasting demand, establishing optimal reorder points, defining safety stock thresholds, and efficiently managing supply and distribution lead times.
The ultimate objective is to ensure the optimal quantity of inventory is available precisely when and where it’s needed, at the most favorable cost.
The Perilous Trap of Overfitting
Inventory management poses several challenges, especially in today’s dynamic business environment. Some of the key challenges include:
⦿ Demand Variability: Fluctuating customer demand makes accurate forecasting difficult.
⦿ Lead Time Variability: Unpredictable lead times from suppliers can result in stockouts or excess inventory.
⦿ Seasonality and Trends: Sales patterns influenced by seasons and trends require adaptive inventory strategies.
⦿ Multiple SKUs: Businesses with a large number of products face complexity in managing inventory for each SKU.
The Business Perspective: Beyond Accuracy
Before diving into ML-driven inventory optimisation, certain prerequisites must be in place:
⦿ Data Quality: Clean, accurate, and reliable data is crucial for ML algorithms to make accurate predictions.
⦿ Historical Data: A rich dataset of past sales, customer behaviour, and supplier performance is essential for training ML models.
⦿ Domain Knowledge: Understanding the nuances of the business, market trends, and supply chain dynamics is vital for effective inventory optimisation.
Machine Learning Applications in Inventory Management
Machine learning offers a range of advanced techniques to tackle inventory optimisation challenges:
Demand Forecasting and Sensing
ML models can analyse historical sales data, seasonality, promotions, and external factors to predict future demand more accurately.
Reorder Point (ROP) Optimisation:
Determining the optimal ROP ensures that inventory is replenished just in time to avoid stockouts while minimising excess inventory.
Safety Stock (SS) Calculation:
ML algorithms can calculate safety stock levels based on demand variability, lead times, and desired service levels.
Dynamic Replenishment
ML systems can continuously adjust reorder points and safety stock levels in response to changing demand patterns & lead times.
Advanced Techniques in Inventory Optimisation
Reinforcement Learning: ROP & SS
Reinforcement learning (RL) is a powerful ML technique where an agent learns to make decisions by interacting with an environment to maximise rewards. In inventory optimisation, RL can be used to dynamically adjust reorder points and safety stock levels based on real-time data and feedback.
Dynamic Network Quantisation (DNQ)
DNQ is a technique that optimises the structure of neural networks to reduce computational complexity while maintaining accuracy. In inventory management, DNQ can be used to build efficient forecasting models that consume less computational resources without sacrificing performance.
Enforcement Learning
Enforcement learning is a subset of ML that focuses on decision-making and control in dynamic environments. In inventory optimisation, enforcement learning algorithms can learn optimal inventory policies by interacting with the system over time. This enables adaptive and responsive inventory management strategies.
Stochastic Optimisation
Stochastic optimisation methods, such as stochastic gradient descent and simulated annealing, are valuable for handling uncertainty and randomness in inventory management. These methods can help in finding near-optimal solutions for complex inventory optimisation problems.
