INTRODUCTION

1.1 Background of the study

The integration of smart sensors into logistics operations has revolutionized the monitoring and tracking of goods in logistics operation. Transforming the way businesses manage their supply chains, Intelligent and communicative smart sensors have changed the game by allowing for real time process monitoring and revolutionizing the logistics process from start to finish. This study explores how smart sensors can revolutionize the logistics industry. First, smart devices were study in-depth and their various features were equally examined, such as GPS tracking, RFID scanning, temperature and humidity sensors, package integrity assessment, vibration and acoustic sensors, and environmental monitoring. By conducting a comprehensive investigation, this research paper aims to scrutinize the data collecting ability of these sensors. The study will focus on their potential for gathering an abundance of information regarding cargo whereabouts, surrounding environment conditions, physical soundness, and equipment efficiency These advanced sensors, which form part of the broader Internet of Things (IoT) framework, continuously provide vital data on various parameters such as location, temperature, humidity, vibration, and more (Kwok, 2015). This real-time monitoring plays a crucial role in safeguarding the quality and integrity of goods, particularly in industries like food and pharmaceuticals where precise conditions are paramount (Lee, 2013).

The benefits of smart sensors in logistics are multifaceted. For instance, real-time monitoring enables logistics providers to optimize their routes and reduce transit times, leading to cost savings and improved customer satisfaction (Bhatia, 2017). Additionally, smart sensors can detect any tampering or damage to goods during transit, enabling logistics providers to take prompt action and minimize losses (Wang, 2019).

Maersk, a global leader in shipping and logistics, stands out as a prime example of leveraging smart sensors to elevate supply chain visibility and efficiency. Through the implementation of these sensors (Maersk, 2020), Maersk can actively monitor the condition of goods in real-time, ensuring optimal storage and transportation conditions. This not only aids in reducing spoilage and waste but also enhances customer satisfaction by offering transparency and real-time updates on the status of their goods.

The use of smart sensors in logistics has been shown to have a positive impact on the environment. By optimizing routes and reducing transit times, logistics providers can lower their carbon emissions and minimize their environmental footprint. Additionally, smart sensors can help logistics providers to identify areas of inefficiency in their operations and make data-driven decisions to improve their sustainability. For instance, a study conducted by Li (2018) investigated the impact of smart sensors on logistics operations. The study found that the use of smart sensors in logistics reduced transit times by 30% and improved delivery accuracy by 25%. This significant reduction in transit times and improvement in delivery accuracy can be attributed to the real-time monitoring capabilities of smart sensors, which enable logistics providers to track the location and condition of goods in real-time.

In a global supply chain, logistics activities can only be well executed with the monitoring of stages and quality of goods from the point of production to the point of consumption. Smith et al. (2018), the authors highlighted the benefits of using smart sensors for real-time monitoring and tracking of goods in the logistics industry. The research emphasized how smart sensors enable real-time data collection, allowing companies to track the location, condition, and status of goods throughout the supply chain. This level of visibility not only enhances operational efficiency but also enables proactive decision-making and risk management. Jones and Brown (2019) explored the impact of smart sensors on inventory management and supply chain optimization. The researchers found that the integration of smart sensors in warehouse management systems can significantly improve inventory accuracy, reduce stock outs, and streamline order fulfillment processes. By providing real-time insights into inventory levels and movement, smart sensors help companies optimize their inventory levels and prevent costly disruptions.

The integration of smart sensors into logistics has greatly improved the way businesses manage their supply chains. These sensors can track and monitor goods in real-time, allowing for more efficient and effective management of the logistics process. This includes tracking the location of goods on transit, monitoring environmental conditions such as GPS trackers, RFID scanners, temperature and humidity sensors, package integrity assessors, vibration and acoustic sensors, and environmental monitors. Through their profound capability to collect extensive data on cargo whereabouts, environmental conditions, and physical integrity, these sensors empower businesses to make more informed decisions, optimize supply chain operations, and ensure the quality and safety of goods. Detecting potential issues, before they become major problems. By using smart sensors, businesses can optimize routes, reduce transit times, and improve the overall efficiency of their logistics operations. This can lead to cost savings, reduced waste, and improved customer satisfaction. In short, smart sensors are revolutionizing the logistics industry by providing real-time information and enabling businesses to make data-driven decisions

1.2 The statement of the problem

In the globalized economy, businesses are increasingly focused on optimizing their supply chains, particularly in the monitoring and tracking of goods as they move across various stages of the distribution process. Efficient tracking and monitoring mechanisms ensure timely delivery, reduce operational costs, and improve customer satisfaction. As the logistics sector continues to grow, integrating advanced technologies such as smart sensors into the supply chain has gained substantial attention. Smart sensors have the potential to revolutionize goods tracking by providing real-time data, improving accuracy, and enabling proactive problem-solving in case of disruptions.

However, despite the significant technological advancements in logistics sectors, many businesses still face challenges related to the efficient monitoring and tracking of goods. In Douala, Cameroon, where Maersk operates as a key player in logistics and transportation, the tracking and monitoring of goods can still be prone to inefficiencies, delays, and data inaccuracies. Traditional methods of tracking, such as manual processes or basic barcoding, often result in gaps in information, human errors, or an inability to make timely decisions in case of unforeseen circumstances. These limitations are particularly noticeable in an increasingly complex logistics environment, where goods are moving across multiple touch points in the supply chain.

The introduction of smart sensors in Maersk Douala has, enabled real-time monitoring and tracking of goods, providing valuable insights into their location, temperature, humidity, and other important parameters. These sensors have the potential to significantly improve the visibility, security, and reliability of goods in transit. Moreover, smart sensors could enhance data-driven decision-making, optimize route planning, and mitigate risks, such as theft or spoilage of perishable goods.

Despite the promising potential, there is limited research on the practical application and effectiveness of smart sensors in the context of monitoring and tracking of goods in Douala, especially within the operations of Maersk. Questions remain regarding the impact of these sensors on operational efficiency, cost reduction, and overall supply chain performance. Furthermore, there are concerns about the initial implementation costs, integration with existing systems, and the extent to which the supply chain can rely on these technologies for accurate and reliable information.

Therefore, this research seeks to evaluate the role of smart sensors in real time monitoring and tracking of goods at Maersk, Douala. By evaluating the impact of these sensors on supply chain performance, the study aims to provide insights into how businesses in Douala and similar regions can benefit from adopting smart technologies in logistics. The research will also explore the challenges faced by businesses in implementing these technologies and propose solutions for overcoming these barriers. Ultimately, this study aims to contribute to the understanding of how smart sensors can enhance the efficiency, security, and sustainability of goods tracking in the logistics sector, with a particular focus on Maersk Douala as a case study.
