A modular configuration-based rapid verification and validation framework combining analytical and simulation methods for intelligent manufacturing systems

Abstract

Verification and Validation (V&V) are crucial steps in the design to operation process of manufacturing systems to ensure the accuracy, safety, and reliability. The development of intelligent manufacturing technology and the acceleration of market changes are driving the increase of complexity and flexibility of manufacturing systems and the shortening of development cycles. These enhance the comprehensiveness, efficiency, and automation requirements of V&V. However, existing V&V schemes and cases cannot fully utilize the complementary advantages of analytical and simulation methods. It is difficult to meet the effective V&V requirements of complex intelligent manufacturing systems. This study proposes a modular configuration-based manufacturing system V&V framework combining analytical and simulation methods for rapid V&V of manufacturing systems. The construction method of modular configurations of manufacturing systems is explored. The modular configuration has been divided into the component function, system logic, and joint model sub-configurations and modularly packaged and integrated based on Asset Administration Shells (AAS). A rapid V&V process for manufacturing systems has been established. This process employs a test-module-driven approach to achieve configuration-based V&V testing of manufacturing systems. It supports synchronized co-simulation with equipment, software, and models in the loop. Finally, a simple manufacturing system V&V case was provided as an implementation reference. The proposed framework can demonstrate the rapid V&V of intelligent manufacturing systems and contribute to the development of automated V&V tools.
