Introduction: The impact of the Internet of Things (IoT) on product quality, due to the complexities of production processes and the multitude of influencing factors, requires thorough and comprehensive investigation. IoT technology enables organizations to monitor their processes with high precision and obtain real-time and accurate information on the status of equipment and products. This study was designed to examine the effects of IoT on reducing waste and improving equipment performance in various industries. In this regard, it identifies key variables influencing production processes and models their behavior.
Methods: To analyze the behavior of key variables, the system dynamics method was employed. This method makes it possible to simulate variable changes over time and examine the complex relationships among them. Since numerous variables affect product quality, mathematical modeling methods do not appear suitable. Therefore, using simulation and complex systems analysis methods—which can examine nonlinear relationships and interactions between variables—provides a more effective solution. After developing a causal loop diagram based on key variables influencing product quality, waste, and cost, a stock-and-flow diagram was drawn, and model validation was carried out using sensitivity and boundary condition tests. Following the analysis of results, improvement scenarios were presented and evaluated.
Results and discution: The validity of the simulated model in this study was confirmed through sensitivity and boundary condition tests. The findings indicate that product waste, after reaching a peak at about 20 months, gradually decreases. This gradual decline may result from improvements in production processes, learning and experience in waste management, or the implementation of preventive measures. The reduced risk of equipment failure and quality control costs also reflects improved system performance. Equipment failure risk is initially high but decreases rapidly. Quality control costs also approach zero by the end of the period. Demand and labor costs show exponential growth, indicating the need for effective planning and management to meet this demand. This increase also demonstrates the direct relationship between demand, workforce requirements, and their related costs. The rising costs may stem from hiring specialized labor and training personnel to gain necessary skills. The results also showed that installation and implementation costs rise exponentially, reaching their maximum at the end of the period. This may be due to the growing need for equipment and infrastructure related to technology usage. In addition, the adoption rate increases over time.
Conclusion: The importance of this research lies in emphasizing the role of modern technologies, especially the Internet of Things, in optimizing processes and reducing costs. The results of this study can help managers and decision-makers in industries make better technology investment decisions and improve system quality and efficiency. This research can also serve as a basis for further studies on IoT applications in various industries and contribute to the development of effective solutions for performance improvement and waste reduction.
