A Data Model for Design Objects
نویسندگان
چکیده
Modeling concepts for handling structural data of hierarchically composed complex objects are presented. A complex object is modeled as an hierarchy of interfaces and an im plementation. Objects sharing the same interface at any level have same attributes and attribute values up to that level in the hierarchy. This structuring facilitates storage of multiple object versions and their subsequent reuse in design databases, &here multiple versions of design artifacts are routinely created and maintained. Other important concepts needed for design databases are presented, and in particular two types of instantiation parametric instantiation, and conditional instantiation are proposed.

Design of Manufacturing Cells with Two- Phase Model and A Heuristic Algorithm
A Two-phase model for configuring a cellular manufacturing system is proposed. In phase (I), for the first time, number of cells is considered as a decision variable. In phase (II), pursing two different objectives, one minimization of underload and the other, maximization of similarity of parts within a group, the design procedure is performed. As one cannot have these two objects together, a ...
متن کاملPresenting a Morphological Based Approach for Filtering The Point Cloud to Extract the Digital Terrain Model
The Digital terrain model is an important geospatial product used as the basis of many practical projects related to geospatial information. Nowadays, a dense point cloud can be generated using the LiDAR data. Actually, the acquired point cloud of the LiDAR, presents a digital surface model that contains ground and non-ground objects. The purpose of this paper is to present a new approach of ex...

متن کاملOn Attributes of Objects in Object-Oriented Software Analysis
One of the modern paradigms to develop a system is object oriented analysis and design. In this paradigm, there are several objects and each object plays some specific roles. There is a sequence of activities to develop an analysis model. In the first step, we work in developing an initial use case model. Then in the second step, they identify a number of concepts and build a glossary of partic...
متن کاملThe lterative Nature of the Engineering Design Process: a Telescopic Revision Model (RESEARCH NOTE)
The satisfying of human needs through designing technical objects requires the compromisation and settling of various conflicting criteria at different stages of the engineering design process. The need for back and forth adjustment of design specifications, concept finding, and design embodiment can be considered to be carried out in a telescopic review fashion. The present study is concerned ...
متن کاملComparing Model-based Versus K-means Clustering for the Planar Shapes
In some fields, there is an interest in distinguishing different geometrical objects from each other. A field of research that studies the objects from a statistical point of view, provided they are invariant under translation, rotation and scaling effects, is known as the statistical shape analysis. Having some objects that are registered using key points on the outline...
