Essential Supply Chain Management Concepts and Strategies
Influencing Factors on Supply Chain Management
The modern supply chain is shaped by several critical drivers:
- Globalization
- Urbanization
- Demographic Change
- Technology and Digitalization
- Sustainability
- Economic Crises and Structural Breaks
Why Do Companies Keep Inventory?
Companies maintain inventory to ensure product availability, absorb differences between supply and demand, capitalize on purchasing opportunities, and protect against supply disruptions or price fluctuations. However, maintaining inventory also generates significant storage, financial, and operational costs.
Inventory Classification Techniques
What is ABC Analysis?
ABC Analysis is an inventory classification technique that groups products according to their economic importance. Items are ranked by their annual inventory value (quantity × price) and divided into three categories: A, B, and C. This helps companies focus management efforts on the most valuable items.
What is XYZ Analysis?
XYZ Analysis is an inventory classification method based on demand variability. It groups products into categories according to demand predictability:
- X items: Stable demand.
- Y items: Seasonal or moderate variation.
- Z items: Highly irregular demand.
Reorder Point vs. Order Interval Models
The primary differences between these two inventory models are:
- Reorder Point Model: An order is placed whenever inventory reaches a predefined reorder point.
- Order Interval Model: Inventory is reviewed at fixed time intervals, and the order quantity is adjusted according to the current inventory level.
Strategic Logistics Concepts
What is Supplier Integration?
Supplier Integration involves close collaboration between a company and its suppliers through the sharing of information, planning, and processes. The objective is to improve coordination, reduce costs, increase service levels, and enhance supply chain efficiency.
What is Value Stream Analysis?
Value Stream Analysis is a Lean Management tool used to map all activities involved in producing a product. It helps distinguish between value-added and non-value-added activities, identify waste, and improve process efficiency.
How is a Distribution Tariff Calculated?
A distribution tariff is calculated by identifying every logistics activity involved in the shipment (pre-carriage, handling, main leg, handling at the forwarder, on-carriage, and administration). Each activity is assigned a cost using an appropriate cost driver (such as pallets or orders), summed, and adjusted by a risk or profit margin.
What is LP Modelling in Distribution?
LP (Linear Programming) Modelling in distribution determines the optimal allocation of goods from plants or warehouses to customers while minimizing total transportation costs and satisfying capacity and demand constraints.
What is Cross-Docking?
Cross-Docking is a logistics strategy where incoming goods are transferred directly from inbound vehicles to outbound vehicles with little or no storage. Its objective is to reduce inventory, handling time, and logistics costs while improving delivery speed.
What is Process Automation?
Process Automation utilizes technology, software, and automated systems to perform repetitive business or logistics processes with minimal human intervention. Its objective is to increase efficiency, reduce errors, improve quality, and lower operating costs.
