Process of Object-Oriented Design of Gear Size Ranges. Part I: Analysis

Abstract

Design process can be divided into stages of analysis and synthesis. This paper presents the application of the object-oriented technique to the analysis as well as theoretical considerations concerning to design of gear size ranges. This analysis consists in decomposition of the designed artefact (a gear) according to the rule “from general to details view”. The basics of the object-oriented analysis were formulated. Furthermore, design phases and the objects related to theses phases were discussed. The following models have been considered: hierarchical model, entity-relationship model, data-flow model and object model. Analysis is additionally connected with interactions between particular design phases.

Process of Object-Oriented Design of Gear Size Ranges. Part II: Synthesis

“…As mentioned in Part I [1] concerning object analysis, the design process of object-oriented methodology consists of object analysis and object synthesis as implementation with assessment. This paper presents the following phases of synthesis, i.e., embodiment design, detailed design, testing, initiation and maintenance [5,6,8,10].…”

“…In the Part I of this paper [1], the analysis of original methodology of shaping the constructional form of gear size ranges was presented. The basis of the methodology is creating models in the order of classes, subclasses and objects for a given super-class [2][3][4].…”

“…It is a typical object analysis in which the rule "from general to details view" is used, which also appears in design theory [5][6][7][8][9][10]. Object analysis of a studied methodology is explained in details in the Part I of this paper [1] and concerns:  theoretical basis,  stages of object designing,  partition of the problem making up the super-class into classes and objects,  determining methods and attributes in classes,  data-flow between classes and objects,  models used in the design phases. This paper, concerning object synthesis, is devoted to practical application of the methodology that is implementation.…”
