A bubble diagram is understood as a graphic medium which bridges program and plan in architectural design process. The role of a bubble diagram is either to generate or to explain a plan in relation to its program. Despite the explicit role of a bubble diagram in architectural design process, what a bubble diagram indicates exactly is very ambiguous. Here I attempt to reveal the nature of the bubble diagram more sharply. My main argument is that the ambiguity of a bubble diagram results from the fact that it is used to range two different types of representational formats. Reviewing the theories of shape recognition and shape representations in vision science, I will also argue that the procedural description of architectural design process should be criticized and that the focus of design method research has to be shifted into the representational format of form description in architectural design process.

Recently, because of the rapid remarkable development of the digital media, contemporary society is continuously extending and changing over the limitation of the human recognition. But in the field of architectural form creation, a diagram used in the design process of the past is not enough to reflect a complication, contingent and multiple quality of these contemporary society. So, to reveal the rhizomorphous and non-hierarchial qualify of the contemporary digital network society, architecture became necessary to use the diagram with digital media which have various possibilities to present architect's abstract images that the diagram of the past couldn't do. Therefore, this study proposes that the process for creating architectural form with the digital diagram be a alternative to conquest the limits of contemporary architecture, so it present the complicate and contingent quality of contemporary society. Furthermore, it examines the quality and possibility of the diagram by understanding the creation and transformation of the digital diagram, and how to apply to the actual architecture process of the creating form.

There are PFD(Process Flow Diagram) and P&ID(Piping and Instrument Diagram) for designing and managing chemical process efficiently. They provide the operation condition and equipment specifications of chemical process, but they do not provide the reliability of chemical process. Therefore, in this study, Reliability Flow Diagram(RFD) which provide the cycle and time of preventive maintenance has been developed using Directed Graph Analysis methodology. Directed Graph Analysis methodology is capable of assessing the reliability of chemical process. It models chemical process into Directed Graph with nodes and arcs and assesses the reliability of normal operation of chemical process by assessing Directed Graph sequential. In this paper, the chemical process reliability transition according to operation time was assessed. And then, Reliability Flow Diagram has been developed by inserting the result into P&ID. Like PFD and P&ID, Reliability Flow Diagram provide valuable and useful information for the design and management of chemical process.

In contemporary design conditions, the focus of landscape architecture has shifted from 'form' to 'process.' Various experimental diagrams have been proposed to overcome the limitations of conventional form-oriented landscape design. This study aims to reconsider theoretically and critically the modes and mechanism of diagrams in recent landscape architectural design. It also explores the operational capabilities of diagram in design process. Although the traditional diagram has served as explanatory and representational graphics in design, contemporary designers emphasize the generative function of diagram on the basis of Gilles Deleuze's theory of 'diagram as abstract machine.' They manifest and practise that diagrams call generate forms and proliferate spaces in their design development. This paper examines current examples of generative and constructive diagrams produced by leading designers. However, the author illuminates another significance of diagram: the diagram as strategic media of design. Contemporary environments and conditions of design, such as the complexity of city and the interactivity of new economy, call for new design intelligence and strategic design. These situations require alternative media in design process. In this context, the diagram can function as strategic media of dynamic and flexible design. This is why contemporary landscape theory and practice have to give attention to diagrams.

Among the architects who use diagrams as a digital design process, especially through Peter Eisenman and Ben van Berkel's works, we have specifically got the meaning of their diagrams. Their diagrams act as 'the block of becoming' and we can regard the diagrams not only as a tool of devenir including architect's root thoughts beyond a tool of schematic presentation, but also as architect's intention including devenir thought. And in the case of diagrams which the architects use, we can recognize that architects' intentions are to think that Deleuze's 'machine abstraite' evolve the diagram into various and transformed form. That is to say, Peter Eisenman interprets the machine abstraite as a root thought of devenir by using diagram as medium to reveal the virtual. And Ben van Berkel transforms the diagram by including all external conditions into selected diagram which shows the abstract relations to the elements. We can get the meaning of the machine abstraite from these cases well. This study will play an important role in giving good usage of the diagram in making a form of contemporary digital architecture and showing the direction of form creation field.

In metal forming technologies, the stamping process is one of the significant manufacturing processes to produce sheet metal components. It is important to design stamping process which can produce sound products without defect such as fracture and wrinkle. The objective of this study is to propose the feasible formability diagram which denotes the safe region without fracture and wrinkle for effective design of stamping process. To determine the feasible formability diagram, FE-analyses were firstly performed for the combinations of process parameters and then the characteristic values for fracture and wrinkle were estimated from the results of FE-analyses based on forming limit diagram. The characteristic values were extended through training of the artificial neural network. The feasible formability diagram was finally determined for various combinations of process parameters. The stamping process of turret suspension to support suspension module was taken as an example to verify the effectiveness of feasible formability diagram. The results of FE-analyses for process conditions within fracture and wrinkle as well as safe regions were in good agreement with experimental ones.

Currently there are a variety of different tools may be used to analyze, model, describe and document a business process. However, it is difficult to exchange the information of a business process created in different tools because of the distinct information formats used in different tools. The XML Process Definition Language (XPDL) of the Workflow Management Coalition (WfMC) forms a common interchange standard that enables products to continue to support arbitrary internal representations of process definitions with an import/export function to map to/from the standard at the product boundary. Generally a business process model can be represented by the UML activity diagram, but there is a difficult task to directly generate an XPDL document from a business process model represented by the standard activity diagram. In the paper we will propose an approach to generate an XPDL document from a business process model represented by the extended UML activity diagram.

Company A should maintain myriad conversion tools for the purpose of making a geometric compilation of navigation maps. Company A is already using complex compilation tools, which are tailored to geographical areas and various GPS models. However, due to frequent requirement and personnel changes, there is an endless challenge for perfect tool configuration and multiple map consolidation. To solve this problem, Company A launched a process automation project using Graphviz, which is an open source workflow graph visualization software. Before implementation, they had to document their current map compilation processes and then match it with the applicable conversion tool. For effective representation of process controls, a new graphical process notation is designed, i.e. Y Block diagram. The authors will compare Y Block diagram with other process notations and explain why Y Block diagram is more useful for tool based business processes such as digital map generation processes.

Proposed in this paper is a standard-compliant business process modeling tool which is based on the UML(Unified Modeling Language) activity diagram and produces an XPDL(XML Process Definition Language) file as an output. The XPDL is a standard process definition exchange format by WfMC (Workflow Management Coalition). To develop an UML/XPDL-based modeling tool, the mapping of modeling elements between activity diagram and XPDL format is conducted after the detailed analysis of each modeling specification. As a result of this mapping, it is revealed that modeling elements of each activity diagram and XPDL must be expanded. So new modeling elements are identified and added to each specification. Based on this mapping, the prototype system is developed, and the usefulness of the developed system is shown through the case study.
