2.3 Literature Review
2.3.1 History and Lead-up to the Present
Early 20th-century facility layout theories focused on making workplaces more efficient and
productive. Frederick Taylor's Principles of Scientific Management (1911) emphasized
organizing workspaces strategically to improve workflow efficiency and reduce unnecessary
movements. Around the same time, Frank and Lillian Gilbreth's motion studies were innovative
for their era; their research aimed to enhance productivity and reduce worker fatigue,
significantly influencing the ergonomic arrangement of workstations and the design of more
efficient work environments (Gilbreth and Gilbreth, 1924). Their work set the foundation for
future improvements in industrial engineering and facility layout planning. In the aftermath of
World War II, the burgeoning manufacturing industries underscored the necessity for advanced
facility layout planning to manage increasingly complex operations and expanded production
capacities. Apple (1977) highlighted this era as a turning point that necessitated more
sophisticated approaches to optimize the use of space and resources within industrial settings.
Moving forward in history, Tomkins et al. (2010) introduced computer-aided design (CAD)
and simulation in the 1960s and 70s, drastically changing layout planning. These technologies
allowed for precise and flexible designs, enabling the simulation of operations before actual
implementation. The late 20th and early 21st centuries witnessed significant advancements in
facility layout planning with the introduction of lean manufacturing principles, which
emphasize waste elimination, enhanced workflow, and optimized space utilization. Womack
and Jones (1996) highlighted that these principles not only streamline production processes but
also contribute to creating more value in corporations by improving operational efficiencies.
The era also welcomed the integration of technologies like the Internet of Things and Artificial
Intelligence, which allow for real-time adjustments in facility layouts based on predictive
analytics (Zhong et al., 2017).
2.3.2 Warehouse Layout Optimization
Warehouse layout optimization involves strategically arranging the physical layout of a
warehouse to maximize space utilization, minimize travel distances, and enhance operational
efficiency. It stands at the forefront of enhancing logistical efficiency, an endeavour crucial to
the operational success of any warehouse system. Warehouse Layout Optimization is a key
focus of Andrada and Biscocho (2019) who emphasized the difficulties in the facility layout
and design of sugar plants in the Philippines, suggesting a more nuanced approach to
operational efficiency. They suggested approaches such as time study, ABC inventory analysis,
and Systematic Layout Planning (SLP) used to enhance material location within warehouses.
Their goal was to reduce the time and distance required in search and retrieval activities, which
improved operational efficiency. Similarly, in their article written by Wang and Ke (2019)
titled "Spatial Layout Optimization of Warehouse Based on Improved SLP" they focused on
optimizing warehouse spatial layouts with an upgraded SLP technique. It seeks to improve
logistics efficiency by carefully examining and integrating logistics and non- logistics aspects
to increase turnover and space utilization rates.
In their study of warehouse layout optimization, Saderova et al. (2020) delve into the
complexity of improving rack system designs to boost operational efficiency, that extend to
operations such as receiving goods and storage, inventory management, internal movement and
distribution. The study objectively evaluates several rack system layouts, including standard
and V-shaped aisles, and compares their performance using important criteria such as rack field
count, pallet accommodation capacity, and total warehousing space utilization. Georgise,
Assefa, and Bekele (2020) also explore the complexities of designing a different warehouse
layout with the aim of optimizing space utilization. Their research begins on an attempt to
restructure existing layouts to alleviate congestion difficulties, using the Analytical
Hierarchical Procedure (AHP) to thoroughly assess alternative options. This strategy seeks to
maximize space use, emphasizing the importance of layout optimization in improving the

the consequence of ineffective layouts that increase travel distances for workers, leading to
slower operations and a higher error rate. These inefficiencies not only impact financial
outcomes but also compromise customer satisfaction, underscoring the urgency for strategic
layout redesign to bolster warehouse operations. Additionally, Wang and Ke (2019) identify
problems like poor space utilization and unclear functional area delineation, which can cause
congestion and logistical bottlenecks, thereby escalating operational costs and impeding the
warehouse's capacity to efficiently fulfil customer demands.
The study by Georgise, Assefa, and Bekele (2020) at Modjo Dry Port echoes similar concerns,
where cargo congestion and operational bottlenecks threaten the supply chain's reliability due
to the port's inability to handle the surge in container volume. This scenario highlights the need
for alternative warehouse layouts to alleviate congestion and enhance operational flow. On
another front, the challenge of embedding sustainable practices within warehouse operations is
dissected by Ali, Kaur, and Khan (2023), who argue that despite the initial investment and

analytics tools and techniques, warehouses can analyse vast amounts of data related to
inventory levels, order volumes, customer preferences, and operational performance. This
enables warehouses to forecast demand more accurately, optimize inventory levels, and
improve resource allocation. A case study conducted in a leading Logistics and Supply Chain
company demonstrates the significant competitive advantage gained through the deployment
of data analytics and reporting tools. By leveraging these tools, companies can ensure timely
delivery of products, enhance customer service by optimizing inventory levels, and establish
themselves as technology leaders in the logistics industry. Moreover, the research highlights
the clear return on investment provided by data analytics tools, enabling better-informed
decision-making, business growth, and improved capacity and capability. This transformative
impact of data analytics on warehouse management systems is documented by Andiyappillai
(2019) in the International Journal of Computer Applications.
2.3.7 Inventory Management and Material Handling
Effective inventory management and material handling play a pivotal role in maintaining
optimal stock levels, minimizing stockouts, and ensuring accurate order fulfilment. At PT.
MDA, (a company) the implementation of inventory management techniques such as
Economic Order Quantity (EOQ) and Safety Stock has proven instrumental in enhancing
warehouse performance. These guidelines enable the company to strategically manage
inventory levels, ensuring sufficient stock without excess, even amidst market fluctuations.
Kurniawan et al. (2024) highlight the significance of such practices in their study, emphasizing
