IwC Special Issue “Feminism and HCI: New Perspectives” Special Issue Editors’ Introduction

As a word and as a set of theories and practices, feminism is a poorly understood concept. However, feminist perspectives have a lot in common with user- and value-centered design processes such as those espoused within the field of Human Computer Interaction. Examples include consideration of alternative viewpoints, considerations of agency (who get to say/do what and under what circumstances) and the development of reflective and reflexive methods for understanding how, when, where and why people do what they do. In the “Feminism and HCI: New Perspectives” special issue, we have invited researchers and practitioners to reflect on the ways in which feminist thinking, theory, and practice can and does have an impact on the field of Human Computer Interaction. This introductory editorial offers more background to our view that there is great value to understanding the actual and potential impact of feminist thinking on HCI, followed by a précis of each paper. We close with some observations regarding common themes, points of contention and possibilities for future work.     

Preliminary design and manufacturing planning integration using web-based intelligent agents

Software agents have been increasingly used in the product and process development in industry over the past years due to the rapid evolvement of the Internet technology. This paper describes agents for the integration of conceptual design and process planning. Agents provide mechanisms to interact with each other. This mechanism is important since both of those processes involve negotiations for optimization. A set of design and planning software agents has been developed. These agents are used in a computer-based collaborative environment, called a multi-agent platform. The main purpose of developing such a platform is to support product preliminary design, optimize product form and structure, and reduce the manufacturing cost in the early design stage. The agents on the platform have access to a knowledge base that contains design and planning rules. These rules are derived from an analysis of design factors that influence process and resource planning, such as product material, form, shape complexity, features, dimension, tolerance, surface condition, production volume, and production rate. These rules are used by process planning agents to provide process planners with information regarding selecting preliminary manufacturing processes, determining manufacturing resources, and constructing feedback information to product designers. Additionally, the agents communicate with WEB servers, and they are accessible by users through Internet browsers. During performing design and planning tasks, agents access the data pertinent to design and manufacturing processes by the programming interfaces of existing computer-aided design (CAD) and manufacturing system. The agents are supported by a developed prototype agent platform. The agents and the platform enable the information exchange among agents, based on a previously developed integrated design and manufacturing process object model.     

The role of design for manufacturing in system integration

The costs of “over design” to build in recovery tactics for poor design-production match are substantial. Design for manufacturing can greatly improve the design-production match and enhance manufacturing system integration. A model of manufacturing integration is given which emphasizes three major parameters: (1) Corporate planning, (2) Capacity, and (3) Productivity. The model enables an assessment of overall manufacturing system integration. Methods for gathering the required data and analyzing the data to supply the system integration model metrics are given. Design for manufacturing is shown to significantly impact system capacity, production control, and effectiveness of manufacturing system integration.     

Preface: Volume 16, Issue 2

This volume contains the Proceedings of the fifth EXPRESS workshop. The workshop was held in Nice, France, on 7 September 1998, as a satellite event to CONCUR '98.The EXPRESS workshops aim at bringing together researchers interested in the relations between various formal systems, particularly in the field of Concurrency. More specifically, they focus on the comparison between programming concepts (such as concurrent, functional, imperative, logic and object-oriented programming) and between mathematical models of computation (such as process algebras, Petri nets, event structures, modal logics, rewrite systems etc.) on the basis of their relative expressive power.These workshops were originally held as meetings of the HCM project EXPRESS, which has been active with the same focus from January 1994 till December 1997. The first three workshops were held respectively in Amsterdam (1994, chaired by Frits Vaandrager), Tarquinia (1995, chaired by Rocco de Nicola), and Dagstuhl (1996, chaired by Ursula Goltz, Frits Vaandrager and Rocco de Nicola). The fourth workshop, which took place in Santa Margherita Ligure in 1997 and was co-chaired by Catuscia Palamidessi and Joachim Parrow, was organized as a conference with a call for papers and a significant attendance from outside the project. The fifth workshop, EXPRESS '98, was again organised as a (one day) conference, and was also meant as an occasion to discuss on the inheritance of the Express project and possible directions of future research. We had 17 submissions, out of which we selected 7 for inclusion in these proceedings (41%). Additionally, this collection contains the contribution of the two invited speakers, Matthew Hennessy (University of Sussex, UK) and P.S. Thiagarajan (SPIC Mathematical Institute, IN).We would like to thank the authors of the submitted papers, the invited speakers, and the members of the program committee for their contribution to both the meeting and this volume. We also would like to thank INRIA for their help with the local organization, and Michael Mislove for his help with the editing of the proceedings.
