On the Properties of Metamodeling in OWL [PDF]
Journal of Logic and Computation, 2005 A common practice in conceptual modeling is to separate the intensional from the extensional model. Although very intuitive, this approach is inadequate for many complex domains, where the borderline between the two models is not clear-cut. Therefore, OWL-Full, the most expressive of the Semantic Web ontology languages, allows combining the intensional

Multi-Objective Optimization of Production Objectives Based on Surrogate Model
Applied Sciences, 2020 The article addresses an approximate solution to the multi-objective optimization problem for a black-box function of a manufacturing system. We employ the surrogate of the discrete-event simulation model of a batch production system in an analytical ...

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Structural Concrete, EarlyView.Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Model‐Based Systems Engineering in Space Applications: A Comprehensive Literature Review
Systems Engineering, EarlyView.ABSTRACT The growing complexity of space engineering is driving the demand to embrace the adoption of Model‐Based Systems Engineering (MBSE). Although the MBSE is well‐practiced in the space industry, the level of effort and need required to obtain the benefits of MBSE vastly differ across enterprises; this disparity presents a significant challenge to

A Passive Time Reversal Method with a Metamodel for Underwater Source Localization
Journal of Marine Science and EngineeringA passive time reversal method with a metamodel (PTR-MM) is proposed to improve underwater source localization under ocean conditions. PTR-MM eliminates model mismatch errors by replacing the conventional sound propagation model with a Kriging metamodel.
