    Regardless of the historical and cultural collapse of today's contemporary architecture that arose in the aftermath of the advent of modernity, if we look at the process of the emergence of architecture before this era, we see that most architectural monuments in different periods have been able, due to modeling, to possess A distinct and defined style. The study of urban morphology and architectural typology on different scales show that the formation of ancient cities in the Middle East has always been subject to various conditions, including political, social, economic, geographical and cultural conditions. Cultural conditions are the most important and the first parameter in the formation of urban structure in Iranian cities. The city of Shiraz is one of the sample cities. By studying the historical context of Shiraz from the past and reviewing its morphology, it can be understood that the city's structure is based on cultural conditions. The modern city structure in Shiraz is very different from the historical structure that continued to Qajar period that is the finalist historical period of Iranian urbanism.In this paper, by analyzing different parts of the historical texture of Shiraz, the concept and dimensions of changing the pattern of housing based on urban morphology have been analyzed and analyzed. The results of this descriptive-analytic study show that the concept of housing in this city has been changed and the main factor of development has been derived from the inside. Therefore, it can be argued that the core of the forces forming the Islamic cities, based on the concept of housing in the present age, has lost its meaning

    Supporting reinterpretation in computer-aided conceptual design

    This paper presents research that aims to inform the development of computational tools that better support design exploration and idea transformation - key objectives in conceptual design. Analyses of experimental data from two fields - product design and architecture - suggest that the interactions of designers with their sketches can be formalised according to a finite number of generalised shape rules defined within a shape grammar. Such rules can provide a basis for the generation of alternative design concepts and they have informed the development of a prototype shape synthesis system that supports dynamic reinterpretation of shapes in design activity. The notion of 'sub-shapes' is introduced and the significance of these to perception, recognition and the development of emergent structures is discussed. The paper concludes with some speculation on how such a system might find application in a range of design fields

    Programmed design of ship forms

    This paper describes a new category of CAD applications devoted to the definition and parameterization of hull forms, called programmed design. Programmed design relies on two prerequisites. The first one is a product model with a variety of types large enough to face the modeling of any type of ship. The second one is a design language dedicated to create the product model. The main purpose of the language is to publish the modeling algorithms of the application in the designer knowledge domain to let the designer create parametric model scripts. The programmed design is an evolution of the parametric design but it is not just parametric design. It is a tool to create parametric design tools. It provides a methodology to extract the design knowledge by abstracting a design experience in order to store and reuse it. Programmed design is related with the organizational and architectural aspects of the CAD applications but not with the development of modeling algorithms. It is built on top and relies on existing algorithms provided by a comprehensive product model. Programmed design can be useful to develop new applications, to support the evolution of existing applications or even to integrate different types of application in a single one. A three-level software architecture is proposed to make the implementation of the programmed design easier. These levels are the conceptual level based on the design language, the mathematical level based on the geometric formulation of the product model and the visual level based on the polyhedral representation of the model as required by the graphic card. Finally, some scenarios of the use of programmed design are discussed. For instance, the development of specialized parametric hull form generators for a ship type or a family of ships or the creation of palettes of hull form components to be used as parametric design patterns. Also two new processes of reverse engineering which can considerably improve the application have been detected: the creation of the mathematical level from the visual level and the creation of the conceptual level from the mathematical level. © 2012 Elsevier Ltd.

    Framework for Product Lifecycle Management integration in Small and Medium Enterprises networks

    Get PDF
    In order to improve the performance of extended enterprises, Small and Medium Enterprises (SMEs) must be integrated into the extended networks. This integration must be carried out on several levels which are mastered by the Product Lifecycle Management (PLM). But, PLM is underdeveloped in SMEs mainly because of the difficulties in implementing information systems. This paper aims to propose a modeling framework to facilitate the implementation of PLM systems in SMEs. Our approach proposes a generic model for the creation of processes and data models. These models are explained, based on the scope and framework of the modeling, in order to highlight the improvements provided
