Development Of Multi-Objective Model Layout Dynamic Facilities With Uncertainty Of Production In Zone Based Manufacturing Systems
Development of Multi-Objective Model Layout Dynamic Facilities with Uncertainty of Production in Zone Based Manufacturing Systems
Introduction
Dynamic Facility Layout Planning (DFLP) is a crucial aspect of manufacturing facility planning that requires adaptability to changing conditions. These changes can include adjustments between departments, zones, workstations, and machines, taking into account dynamic parameters and drivers. In this study, we identify three main gaps in the literature review of seven studies and three studies, which only consider environmental dynamics related to production demand and resources, schedule dynamics, and sequence of implementing production strategies. Additionally, there are dynamics of rules such as safety, management, government regulations, and standardization.
The development of dynamic models conducted by previous research is generally only applied to continuous layout, which is widely used in chemical-based industries. Meanwhile, the zone-based industry tends to apply the layout of facilities based on a discrete approach, so that the dynamic model is not appropriate to be applied in the manufacturing industry. Previous research has also developed a mathematical model for the zone-based manufacturing industry, but the cost of handling material and the cost of rearrangement is often considered to be conflicting. In this study, both aspects of the cost will be combined to further reflect the reality of the existing system.
Literature Review
Dynamic Facility Layout Planning (DFLP) is a complex problem that has been studied extensively in the literature. However, most of the existing research has focused on continuous layout planning, which is widely used in chemical-based industries. In contrast, the zone-based industry tends to apply the layout of facilities based on a discrete approach. This has led to a gap in the literature, as there is a need for a dynamic model that can be applied to the zone-based manufacturing industry.
Previous research has developed mathematical models for the zone-based manufacturing industry, but these models have limitations. For example, the cost of handling material and the cost of rearrangement are often considered to be conflicting. In this study, we aim to address this gap by developing a multi-objective model that combines both aspects of the cost.
Methodology
The DFLP model developed in this study is a multi-objective model that aims to minimize the cost of handling material and rearrangement costs. The model is developed using a zone-based approach, which takes into account the dynamic aspects of demand, dynamics of process sequences, and resources. The model is also designed to consider the size of dynamic performance in the form of change parameters.
The model is tested in three cases, consisting of dummy data, aircraft industry from literature, and car manufacturing industry. The results show that the model can produce 100 optimal Pareto solutions, which indicates good success. The model also shows that increased flexibility in the layout of the facility can not only reduce costs but also increase operational efficiency.
Results
The results of this study show that the DFLP model developed in this study can produce a variety of optimal solutions. The model is able to provide dynamic layout recommendations with a more adaptive and flexible dynamic size for all cases, although with sacrifice on the aspect of resistance tested by the T test, which results in rejection of the zero hypothesis for the car manufacturing industry.
The success of this model in producing a variety of optimal solutions also gives the confidence that companies can easily adapt to the needs that are constantly changing. The use of the Pareto analysis method in this study helps to explore a variety of possible solutions, so that managers can choose the layout that best suits their specific needs.
Conclusion
This study highlights the importance of developing models that take into account dynamic factors in planning the layout of facilities. The DFLP model developed in this study offers a new perspective for the manufacturing industry in managing changes and challenges encountered. The model becomes a valuable tool to improve efficiency and effectiveness in zone-based industry operations.
Additional Analysis and Explanation
The development of this zone-based DFLP model made a significant contribution to the manufacturing industry, especially in the context of rapid change and uncertain demand. Taking into account dynamic factors such as market demand and process sequence, this model offers a more realistic and applicative approach compared to previous models.
This model also shows that increased flexibility in the layout of the facility can not only reduce costs but also increase operational efficiency. This is very relevant for companies that operate in a competitive and constant changing environment, where the ability to adapt quickly is the key to success.
Future Research Directions
Future research directions include the application of the DFLP model in different industries and the development of more advanced models that can take into account more complex dynamic factors. Additionally, the use of machine learning and artificial intelligence techniques can be explored to improve the accuracy and efficiency of the model.
