Introduction to IoT in Supply Chain

What is the “Internet of Things” (IoT)

The Internet of Things (IoT) is a colloquial term that describes a vast network of “things” outfitted with sensors, software, and other technologies that provide more data than ever. These components enable the objects to connect and share data with other devices and systems across the internet. IoT’s reach spans from mundane household items like a smart toaster or thermostat to complex industrial apparatus such as connected factory machinery. This comprehensive interconnection brings about an integrated global system of systems, thereby shrinking the world into a connected ‘global village’.

IoT Impact on Supply Chain

The influence of IoT technology on supply chain management is genuinely transformative. Businesses can gather real-time insights into their location, status, and condition by integrating sensors into various supply chain assets, including equipment, vehicles, and even the products themselves. This live information feed supports more accurate forecasting, enhanced operational efficiency, and a more resilient and responsive supply chain overall.

Moreover, it opens the door to a new level of customer service – with real-time tracking and updates, businesses can provide customers with accurate estimates and instant updates about their orders, thereby enhancing customer trust and satisfaction.

Big Data and IoT

IoT isn’t merely about connecting devices; it’s about the vast data these devices generate. When properly harnessed and analysed, this so-called ‘Big Data‘ can furnish valuable insights into consumer behaviour, market trends, and inefficiencies within the supply chain. Companies use big data analytics to make data-driven decisions, streamline operations, and improve their bottom line. 

For example, understanding customer usage patterns can help in forecasting demand and inventory management, thus reducing waste and improving service levels.

Benefits of IoT in Supply Chain Over Legacy Concepts

Traditional supply chain processesIOT in Supply Chain
Reactive: Issues are typically addressed after they’ve occurred, which can lead to significant losses.Proactive: IoT enables companies to anticipate and address issues before they happen, thus minimising disruptions.
Linear: Each stage of the supply chain operates sequentially, reducing the overall agility.Circular: Information flows continuously throughout the supply chain, enabling real-time adjustments and improving responsiveness.
Siloed: Information sharing between different supply chain stages is limited, hindering coordination and overall efficiency.Interconnected: IoT fosters seamless communication across all supply chain stages, enhancing coordination and efficiency.

Key Applications of IoT in Supply Chain

Real-Time Tracking

In the world of supply chain, “time is money”. Delays in deliveries, losses, or damages to products can translate into significant financial losses. Here’s where IoT comes in.

By deploying IoT sensors, businesses can enable detailed, real-time tracking of goods throughout the supply chain. These sensors can monitor and transmit data on:

  • location
  • temperature
  • humidity
  • how the package is handled
  • product tampering

This capability is critical in ensuring the safe and timely delivery of products.

For instance, consider the transportation of perishable goods like food items or pharmaceuticals. These items must often be kept at a specific temperature throughout their journey. IoT sensors can continuously monitor the temperature and alert the relevant personnel if there is a deviation, enabling immediate corrective action. This results in reduced wastage and improved quality control.

Smart Warehousing

Warehouse operations have been traditionally labour-intensive and prone to errors. IoT is changing this by introducing automated and smart solutions that enhance efficiency and accuracy.

IoT devices can aid sophisticated inventory management by monitoring stock levels and optimising warehouse space usage. For instance, smart shelves fitted with weight sensors can send alerts when a product’s stock level falls below a predetermined threshold, prompting immediate restocking.

Furthermore, Automated Guided Vehicles (AGVs), governed by IoT systems, can transport goods within the warehouse, reducing labour costs, improving safety, and increasing warehouse throughput. AGVs can work round-the-clock, unlike human labour, which further enhances warehouse productivity.

Predictive Maintenance

Equipment downtime in a supply chain can lead to significant disruptions and losses. IoT enables predictive maintenance – a proactive maintenance approach to reliability engineering that predicts equipment failures before they occur. IoT sensors installed on machinery capture data related to parameters like temperature, vibration, and power consumption. This data is then analysed using machine learning algorithms to identify patterns and anomalies that might indicate a potential failure.

By predicting and addressing issues before they occur, businesses can minimise downtime, save on repair costs, and ensure a smooth supply chain operation.

Challenges and Solutions in IoT Implementation

Despite its numerous advantages, integrating IoT into supply chain operations comes with its unique challenges. These hurdles need to be adequately addressed to realise IoT’s potential fully.

Common Challenges for IoT in Supply Chain

While implementing IoT holds great promise, organisations face several challenges:

  1. Costs: The initial investment required for hardware, software, and infrastructural changes can be substantial.
  2. Data Security and Privacy: With the increased connectivity, the risk of data breaches rises. Protecting sensitive information is critical.
  3. Technology Compatibility: Integrating new IoT systems with existing IT infrastructure can be complex and require significant changes.
  4. Lack of Skilled Personnel: IoT involves sophisticated technologies that require specialised skills to implement and manage effectively.
  5. Lack of Standardisation: With IoT being relatively new, industry standards still need to be developed. This lack of standardisation can cause compatibility issues and hinder scalability.

How to Get Started

Surmounting these challenges necessitates a strategic approach. Here are some steps to get started with IoT implementation in your supply chain:

  1. Identify Specific Use Cases: Start by identifying use cases for IoT that align with your business objectives. This could be anything from improving real-time tracking to optimising warehouse operations.
  2. Conduct Pilot Projects: Before implementing IoT across the board, run small-scale pilot projects to evaluate feasibility and return on investment.
  3. Leverage External Expertise: Collaborate with technology partners who specialise in IoT. Their expertise can help mitigate risks, overcome technical challenges, and ensure a smoother implementation process.
  4. Invest in Training: Invest in training existing employees and hiring new ones with the necessary skills to manage IoT systems effectively.
  5. Adopt a Phased Approach: Instead of a full-scale rollout, consider implementing IoT in phases. This allows for learning and adjustments along the way.

Who Provides IOT solutions

As its a growth area there are many companies getting in on the game. Here’s a couple of examples:

  • Honeywell: Honeywell offers a range of IoT solutions designed to optimize supply chain management. This includes warehouse automation solutions, handheld devices for workers, and sensors for equipment and asset tracking.
  • DHL: Though primarily a logistics company, DHL has invested heavily in IoT technologies to optimize their supply chain and offer better services.
  • Cisco: Cisco provides a suite of IoT products and services that can be used to improve visibility and efficiency in supply chain management.

Conclusion: IoT as a Game Changer

The Internet of Things is more than just a buzzword; it’s the personal computer to the typewriter. With its capacity to enable real-time visibility, predictive maintenance, and smart warehousing, IoT offers substantial benefits. Overcoming the hurdles to its implementation might be challenging. Still, with the right strategies and partnerships, businesses can leverage IoT to propel their supply chain operations into the future.
