Design of Factory Layout through the Integration of Lean Manufacturing and Corelap Algorithm in the Concrete Factory

Introduction

In today's competitive manufacturing industry, companies are constantly seeking ways to improve their operational efficiency and reduce waste. PT. XYZ, a concrete production company, is no exception. With a focus on concrete production, PT. XYZ faces several operational obstacles that hinder production efficiency. One of the main problems is the "Waste of Transportation," caused by a long distance between the Batching Plant department and the casting station. This situation results in a backtracking process, slowing production flow. Additionally, there are activities that do not provide added value (non-value added), such as waiting time (delay) and transportation distance that is too far. This non-value added activity takes a significant time, approximately 10,123.40 seconds.

To overcome this problem, a systematic and efficient approach is needed. Integrating the Lean Manufacturing Method and Corelap Algorithm is the right solution. Lean manufacturing focuses on reducing waste, including reduction of time and transportation distance. On the other hand, the Corelap algorithm is used to design the factory layout optimally so as to minimize the distance between work stations.

The Importance of Lean Manufacturing in Factory Layout Design

Lean manufacturing is a production methodology that aims to minimize waste and maximize value-added activities. By applying Lean manufacturing principles, PT. XYZ can identify and eliminate elements that do not provide added value in the production process. One of the significant results of the implementation of this method is an increase in process cycle efficiency (PCE) by 10.4%. PCE, which was previously low, could increase to 90%, showing that most of the production time is now used for added value activities.

This increase in efficiency also has a positive effect on production capacity. With the improvement of the layout and reduction of waste, PT. XYZ can increase daily production by 13 units, so that the average total production reaches 48 units/day. This will certainly have a positive impact on company profitability, meeting market demand that is increasing without sacrificing quality.

The Role of Corelap Algorithm in Factory Layout Design

The Corelap algorithm is a mathematical model used to design the factory layout optimally. This algorithm takes into account various factors such as the volume of transportation and the frequency of material movement. By using the Corelap algorithm, PT. XYZ can determine the best location for each department in the factory, resulting in an optimal layout.

With the optimal layout, PT. XYZ is not only able to reduce the time spent on transportation but also increases collaboration between departments, which ultimately contributes to overall productivity. The Corelap algorithm helps in minimizing the distance between work stations, reducing the time spent on transportation, and increasing collaboration between departments.

Benefits of Integrating Lean Manufacturing and Corelap Algorithm

The integration of Lean manufacturing and Corelap algorithm at PT. XYZ has shown impressive results in the design of the factory layout. With a focus on reducing waste and increasing efficiency, the company succeeded in increasing production capacity and reducing time that does not provide added value. This solution is not only beneficial for factory operations but also provides significant added value in facing competitive challenges in the concrete manufacturing industry.

Conclusion

In conclusion, the integration of Lean manufacturing and Corelap algorithm at PT. XYZ has demonstrated the effectiveness of this approach in designing factory layouts. By reducing waste and increasing efficiency, PT. XYZ has improved its production capacity and reduced time that does not provide added value. This solution can serve as a reference for other companies that want to improve their operational efficiency and face competitive challenges in the manufacturing industry.

Future Directions

In the future, PT. XYZ can continue to improve its factory layout design by integrating other methodologies and algorithms. Some potential areas for improvement include:

Implementing a total productive maintenance (TPM) program to reduce equipment downtime and improve overall equipment effectiveness (OEE)
Using data analytics and machine learning algorithms to optimize production planning and scheduling
Implementing a just-in-time (JIT) production system to reduce inventory levels and improve supply chain efficiency

By continuing to innovate and improve its factory layout design, PT. XYZ can maintain its competitive edge in the concrete manufacturing industry and continue to provide high-quality products to its customers.
