Supply Chain Management (SCM) 101: Supply Chain Technology Supply Chain Visibility RFID IoT Blockchain Serialization

What This Is

Supply Chain Visibility (SCV) is the ability to track and monitor the movement of goods, services, and information across the supply chain in real-time. This concept is crucial in supply chain management as it enables organizations to make informed decisions, reduce costs, and improve customer satisfaction. For instance, Amazon uses RFID and IoT technology to track packages in real-time, allowing them to provide accurate delivery times and improve their logistics efficiency.

Key Frameworks & Formulas

• SCOR (Supply Chain Operations Reference): A framework for designing and managing supply chains, consisting of five processes: Plan, Source, Make, Deliver, and Return.
• Fisher's Model: A framework for classifying products based on their demand patterns, with two dimensions: variability and lead time.
• EOQ (Economic Order Quantity): A formula for determining the optimal order quantity, calculated as √(2DS/H), where D is demand, S is setup cost, H is holding cost, and Q is order quantity.
• Safety Stock: A formula for determining the optimal safety stock level, calculated as Z × σ × √L, where Z is the Z-score, σ is the standard deviation, and L is the lead time.
• RFID (Radio Frequency Identification): A technology for tracking and identifying objects using radio waves.
• IoT (Internet of Things): A network of physical devices, vehicles, and other items embedded with sensors, software, and connectivity, allowing them to collect and exchange data.
• Blockchain: A distributed ledger technology for recording transactions across a network of computers, ensuring transparency and security.
• Serialization: The process of assigning a unique identifier to each product, allowing for tracking and authentication.

Step-by-Step Application

1. Implement RFID Technology: Install RFID readers and tags in the warehouse and on products to track inventory levels and movement.
2. Configure IoT Sensors: Install IoT sensors in the warehouse to monitor temperature, humidity, and other environmental factors.
3. Integrate Blockchain: Integrate blockchain technology to record transactions and track the movement of products.
4. Assign Serialization: Assign a unique identifier to each product to track and authenticate.
5. Monitor and Analyze Data: Use data analytics tools to monitor and analyze data from RFID, IoT, and blockchain systems.
6. Make Informed Decisions: Use data insights to make informed decisions about inventory management, logistics, and supply chain operations.

Common Mistakes

• Mistake: Assuming that RFID and IoT technology are the same.
  • Correction: RFID is a specific technology for tracking and identifying objects, while IoT is a broader network of devices and sensors.
• Mistake: Believing that blockchain is a replacement for traditional supply chain management systems.
  • Correction: Blockchain is a complementary technology that enhances transparency and security, but does not replace traditional systems.
• Mistake: Failing to consider the costs and benefits of implementing SCV technologies.
  • Correction: Conduct a thorough cost-benefit analysis to determine the feasibility and ROI of implementing SCV technologies.

Exam / Certification Tips

• Tip: Be familiar with the SCOR framework and its five processes.
• Tip: Understand the differences between RFID and IoT technology.
• Tip: Be able to explain the benefits and limitations of blockchain technology in supply chain management.
• Tip: Practice calculating EOQ and safety stock levels using formulas.

Quick Practice Problem

Scenario: A retailer wants to implement RFID technology to track inventory levels in their warehouse. The warehouse has a capacity of 10,000 units, and the average lead time is 5 days. The retailer wants to maintain a service level of 95%. What is the reorder point?

Answer: Reorder point = (Average demand × Lead time) + (Service level × Standard deviation × √Lead time) = (500 × 5) + (0.95 × 10 × √5) = 2500 + 47.4 = 2547.4

Explanation: The reorder point is calculated by multiplying the average demand by the lead time and adding the service level times the standard deviation times the square root of the lead time.
