A new generation of cooperative development paradigm in the tool and die making branch: strategy and technology

To keep up with the changed corporate strategy and sourcing strategy of customers, the tool and die industry is more than ever obliged to improve its development strategy and justify its role within the value chain. The main aims of this research are to (1) comprehend, formalize and explore the new cooperation relationship between product customers and tool and die suppliers based on the rational principles of early supplier involvement (ESI); and (2) develop a new generation of cooperative development strategy, which can provide a powerful tool for a stronger integration of tool maker into the process chain of product development. Making use of EDEN™ software, a supporting environment to implement the new cooperative development strategy in tool and die making branch has been established. The implementation environment comprises three components: enterprise design, product and tool development, as well as benchmarking, which can provide a comprehensive support to cooperative development in the tool and die making branch, not only initial implementation support but more importantly a means to sustain and continuously improve the proposed cooperative development strategy. Individual industrial cases already reveal the potential of this new generation of cooperative development paradigm, which has enlightened that the future tool maker is a highly and competent partner along the value chain of the entire product life cycle.     

On the modeling and generation of service-oriented tool chains

Tool chains have grown from ad-hoc solutions to complex software systems, which often have a service-oriented architecture. With service-oriented tool integration, development tools are made available as services, which can be orchestrated to form tool chains. Due to the increasing sophistication and size of tool chains, there is a need for a systematic development approach for service-oriented tool chains. We propose a domain-specific modeling language (DSML) that allows us to describe the tool chain on an appropriate level of abstraction. We present how this language supports three activities when developing service-oriented tool chains: communication, design and realization. A generative approach supports the realization of the tool chain using the service component architecture. We present experiences from an industrial case study, which applies the DSML to support the creation of a service-oriented tool chain. We evaluate the approach both qualitatively and quantitatively by comparing it with a traditional development approach.     

A web-based formative assessment tool for Masters students: A pilot study

The use of web-based learning and assessment tools is growing in tertiary institutions around the world. To date, very few papers have reported the development and evaluation of a web-based formative assessment tool for postgraduate students. The aim of the present paper was to report on the development and evaluation of an online formative assessment tool for this student group. The web-based formative assessment tool was evaluated by a sample of undergraduate students, postgraduate students and academic staff within a psychology department in order to determine the suitability and sensitivity of the tool. The results of this pilot test suggest that the development of such a tool is both appropriate and feasible for Masters students studying psychology.

Interaction styles in tools for developing virtual environments

This article discusses and compares interaction styles in development tools for virtual environments (VE). The comparison relies on a qualitative empirical study of two development processes where a command language and a direct manipulation based tool were used to develop the same virtual environment application. The command language tool proved very flexible and facilitated an even distribution of effort and progress over time, but debugging and identification of errors was very difficult. Contrasting this, the direct manipulation tool enabled faster implementation of a first prototype but did not facilitate a shorter implementation process as a whole. On the basis of these findings, the strength and weaknesses of direct manipulation for developing virtual environment applications are explored further through a comparison with a successful direct manipulation tool for developing interactive multimedia applications. The comparisons are used to identify and emphasize key requirements for virtual environment development tool interface design.

CAD TOOL FOR IMPLEMENTATION OF FUZZY CONTROLLERS ON FPGAs

In this paper, a computer-aided design (CAD) tool for implementing fuzzy controllers on field-programmable gate arrays (FPGAs) is presented. The developed tool reduces the fuzzy controller to a set of Boolean equations. The output file of the developed tool, which contains the set of Boolean equations, is in an acceptable format for the FPGA development system. The FPGA development system then generates the necessary code to program the FPGA chip. Therefore, the developed design tool together with the FPGA development system represent a complete design automation system for fuzzy controllers. Using this system, a fuzzy controller with speed of 50 M fuzzy logic inferences per second (FLIPS) is realized.
