Simulation forms a cornerstone of modern modular manufacturing systems, providing essential virtual testing capabilities for complex logistics operations. In the context of MODAPTO (Modular Manufacturing and Distributed Control via Interoperable Digital Twins), simulation involves the systematic modeling, execution, and analysis of logistics processes to predict performance outcomes, identify bottlenecks, and evaluate different operational sequences before physical implementation. This digital approach enables risk-free experimentation and optimization across various logistics scenarios.
The fundamental purpose of simulation in logistics operations is to create a virtual representation of material flow, handling equipment, and scheduling decisions. This representation allows manufacturers to test different configurations, evaluate performance metrics, and make informed decisions without disrupting ongoing operations. By simulating logistics operations, organizations can detect inefficiencies, validate proposed changes, and optimize resource utilization across the production environment.
Simulation in the MODAPTO framework is distinctive in how it integrates with Digital Twins, creating a synchronized bridge between physical assets and their virtual representations. The Digital Twin, a virtual replica of the physical manufacturing module, updates its virtual asset in near real-time using IoT sensors. This virtual asset is then transferred and exploited for logistics simulation, enabling the prediction of potential logistics risks and accurate performance forecasting.
This approach aligns with the broader Industry 4.0 vision, which refers to production based on cyber-physical systems that integrate manufacturing, logistics, and distribution. One of the main components of an intelligent factory, based on cyber-physical systems, is the virtual equivalent of a real system in the form of the Digital Twin.
A significant challenge in logistics simulation is managing the enormous volume of data generated. A typical production module can generate thousands of signals per time step, with measurement intervals typically in the millisecond range. Effective monitoring systems must implement strategies for data filtering, aggregation, and prioritization to extract meaningful insights from this deluge of information.
Creating simulation models for modern manufacturing logistics systems requires high effort and in-depth knowledge of production processes. However, digital twins promise several advantages for production optimization and can be used to simulate production systems, which reduce necessary physical test runs and related costs.
Well-implemented simulation creates both operational benefits (immediate issue detection, reduced downtime, improved quality control) and strategic advantages (support for flexible reconfiguration, enabling collective intelligence, advancing sustainable manufacturing practices). As manufacturing evolves toward more modular and reconfigurable approaches, effective simulation becomes increasingly critical as the foundation for adaptive, responsive production systems.
The purpose of the Simulation of Logistics Operations module in this “Train-the-Trainers” program is to equip instructors with comprehensive knowledge and practical skills needed to effectively teach logistics simulation concepts and practices in modular manufacturing environments. This understanding is essential for anyone involved in designing, implementing, operating, or optimizing logistics systems within reconfigurable production environments.
For trainers, mastering this module enables the confident transfer of both theoretical foundations and practical applications of logistics simulation to various manufacturing audiences. The simulation knowledge presented here serves as a critical bridge between abstract logistics concepts and tangible operational improvements, allowing trainers to demonstrate the concrete value of simulation approaches in logistics planning and execution.
The ability to test multiple scenarios before making physical changes to the system (such as improving system design, error avoidance, process optimization, and cost savings) is a key benefit of simulation technology. This simulation capability is central to the digital twin concept in manufacturing, where a digital twin is defined as “a digital representation of a physical object, system, process, entity or some combination thereof, created using data from sensors, Internet of Things (IoT) devices, Industrial Internet of Things (IIoT) devices including Industrial Control Systems (ICS) and other sources to mirror the real-world counterpart in the digital space.”
This module specifically addresses the simulation needs for evaluating different logistics configurations and sequences, supporting decision-making processes in modular manufacturing. Digital twin modeling is revolutionizing the construction industry, especially in modular construction. By creating a digital representation of a modular building or system, project teams can simulate various scenarios, identify potential issues early, and optimize the entire process. This represents a significant advantage over traditional approaches where changes made during implementation may not get communicated back to designers.
The module aligns with the MODAPTO project’s vision of flexible industrial systems composed of modules enhanced by distributed intelligence via interoperable Digital Twins. It supports the materialization of reconfigurability in factory floor operations by providing the simulation tools needed to evaluate different logistics configurations before implementation. This approach enables effective module and production line design, reconfiguration, and decision support based on industrial standards.
