Semantic Modeling and Interoperability in Product and Process Engineering

A Technology for Engineering Informatics


About this book

In the past decade, feature-based design and manufacturing has gained some momentum in various engineering domains to represent and reuse semantic patterns with effective applicability. However, the actual scope of feature application is still very limited. Semantic Modeling and Interoperability in Product and Process Engineering provides a systematic solution for the challenging engineering informatics field aiming at the enhancement of sustainable knowledge representation, implementation and reuse in an open and yet practically manageable scale.

This semantic modeling technology supports uniform, multi-facet and multi-level collaborative system engineering with heterogeneous computer-aided tools, such as CADCAM, CAE, and ERP. This presented unified feature model can be applied to product and process representation, development, implementation and management. Practical case studies and test samples are provided to illustrate applications which can be implemented by the readers in real-world scenarios.

By expanding on well-known feature-based design and manufacturing approach, Semantic Modeling and Interoperability in Product and Process Engineering provides a valuable reference for researchers, practitioners and students from both academia and engineering field.

Table of Contents

Introduction to Engineering Informatics
This work offers a panorama view about a new engineering science discipline: Engineering Informatics. Engineering informatics is an applied information science sub-domain that is scoped to address the information technology (IT) knowledge, methods, models, and algorithms that support engineering and management activities ranging from customer requirements to design and production operations. In this work, a number of key application areas of engineering informatics are analyzed, i.e. product development, measuring product development performance, and concurrent and collaborative engineering. In addition, a special engineering informatics application domain, chemical engineering, is reviewed in order to illustrate an industry-specific scenario. Two fundamental technologies of engineering informatics, object-oriented (OO) software engineering and semantic modeling, are briefly introduced.

A Review of Data Representation of Product and Process Models
Engineering product and process models are essential for the success of the implementation of IT systems in manufacturing companies. They need to have commonly recognized, unified, and global definitions of product entities and process resources and also can be interpreted by various computer programs. For product modeling, four classes of modeling methods are reviewed, i.e., solid product modeling, feature-based product modeling, knowledge-based product modeling, and integrated product modeling. For process modeling, an example application, i.e., chemical process engineering is discussed first to appreciate the modeling elements and constraints. Then a few generic engineering processes, such as engineering change management, are reviewed.

An Example of Feature Modeling Application: Smart Design for Well-Drilling Systems
The reported effort is intended to develop a semi-automated, knowledge-based, and integrated petroleum well-drilling engineering design system, considering various aspects such as drill-string [40] and casing design models. The goal was to significantly increase the dynamic drilling engineering responsiveness to real field changes through the automation of conceptual design and 3D modeling processes. Built-in rules and knowledge are used to develop the conceptual design; the system then automatically generates the assembly configuration and retrieves part specifications from a data sheet to generate the CAD parameter files. These parameter files are used to further generate the full CAD model. The conceptual design and CAD models are integrated in such a way that any changes in the design can be reflected automatically throughout the system. Hopefully, this chapter serves not only as an example application for feature-based design, but also as a research reference for the energy industry to leverage modern informatics advancement for its efficiency and cost effectiveness.

Fundamental Concepts of Generic Features
Feature-based engineering technology enables the current advanced engineering software tools for product and process informatics modeling. However, feature definitions are mostly recognized and limited to individual applications. The authors proposed information integration infrastructure to support multi-stage applications throughout the product lifecycle which is referred to as unified feature modeling scheme. This scheme is centered with a core model representation of a basic feature type, generic feature. This work introduces generic feature class definition, data structure, constraints, and supporting mechanisms.

Unified Feature Paradigm
This work discusses the limitations of the existing feature-based computer systems for concurrent and collaborative engineering, including the loss of engineering intent, “hard-coding” feature semantics, unsatisfactory compatibility, inconsistency, and limited scalability for information sharing among different CAx systems. Such limitations create chaos for inevitable engineering changes within and across different product development stages. The authors introduces a unified feature modeling system to provide the required flexibility and scalability in view of the modern complex engineering. The fundamental mechanisms that enable the unified feature modeling scheme are presented.

Features and Interoperability of Computer Aided Engineering Systems
This work addresses CAx application challenges by investigating their complexity and exploring some initial conceptual solutions. It seems that, theoretically, extended feature technology offers the necessary flexibility in associating entities from different domains with different levels of granularity. A special field of application, i.e., chemical process engineering in oil and gas industry is studied to show the proposed informatics solution. Collaboration of engineers from different domains is discussed in depth due to the complexity and close associations among the activities. Interoperability is the major issue addressed. An innovated integration framework was proposed based on semantic modeling and unified feature technology, and designed to support semantics, patterns, association, and change propagation. Associations between semantic features were illustrated by an example of equipment design.

Feature Transformation from Configuration of Open-Loop Mechanisms into Linkages with a Case Study
This chapter proposes a method for feature synthesis of mechanisms and manipulators from user specifications based on a hybrid approach employing both neural network and optimization techniques. The typical mechanism design modeling problem with the lack of solution convergence observed in optimization is addressed by using a neural network method to generate reliable initial solutions. This chapter also discusses a module by which the validation of prescribed precision configuration points is evaluated.

Feature-Based Mechanism Design
This chapter presents a feature-based concept design method for variational mechanisms. The proposed method integrates dimensional synthesis, mechanical design, and CAD generation with advanced feature technology with minimal designer intervention. Extended feature definitions are used in this research to create a smooth data flow connection between different engineering tools and applications.

A Smart Knowledge Capturing Method in Enhanced Generative Design Cycles
This work proposes a new method to capture and reuse engineering knowledge throughout CAD and CAE interactions with a generative approach. A design development process model was developed to record, interpret, and reuse embedded procedural knowledge with one-time initial interactive effort, and to facilitate CAD and CAE application program code creation. Further, CAD and CAE model updating processes are automated as much as possible by using a common data model (CDM). The proposed method is generic and systematic with combined use of parametric and procedural knowledge. It offers a design automation solution for those products with relatively predictable configurations and constraints.
