| چکیده مقاله |
| The vision of Industry 4.0 and the emerging paradigm of Industry 5.0 are predicated on resilient, human-centric, and sustainable cyber-physical production systems (CPPS), whose realization is fundamentally governed by seamless interoperability. In automated laser manufacturing- a domain characterized by high precision, complexity, and integration of heterogeneous subsystems (lasers, robots, sensors, CNC)- this interoperability is critically hampered by the proliferation of proprietary and semantically disjoint communication protocols. This paper presents a novel systems-theoretic and information-theoretic framework to formally analyze, model, and resolve the interoperability challenge. We deconstruct interoperability into three distinct, hierarchically dependent layers—syntactic, semantic, and pragmatic- and model the manufacturing cell as a directed network where protocol heterogeneity induces structural fragmentation, degrading systemic observability and controllability. Moving beyond simplistic models, we introduce the concept of Interoperability Impedance (ZI), a multivariate function incorporating the number of distinct protocols (n), their inherent complexity (γi), the semantic alignment effort (α), network topology (ϕ), and the maturity of a unifying standard (S). We demonstrate that achieved data utility (Uachieved) decays exponentially with ZI, formally linking technical heterogeneity to the erosion of digital thread fidelity and the feasibility of high-fidelity digital twins. Using OPC Unified Architecture (OPC UA) and its laser-specific companion specifications as a semantic interoperability case study, we illustrate how a standardized information model acts as a universal middleware, collapsing semantic silos. The framework provides a predictive, semi-quantitative toolkit for diagnosing integration bottlenecks, guiding the design of future-proof systems, and justifying strategic investment in open standard. |
