The Journal of Integrated Design and Process Science (JIDPS) is the official journal of the Society for Design and Process Science (SDPS). This journal publishes research findings covering transdisciplinary notions of design and process with a focus on issues that deal with 1) understanding of design and process crossing boundaries of natural, human, and built environments, 2) principles, methods, and tools, and 3) applications of design and process science to engineering and social problems. The journal serves to promote research of transdisciplinary design and process science from different disciplines such as mathematics, computer science, economics, engineering, management science, natural sciences, and social sciences.
The journal is an archival peer-reviewed technical journal publishing the following papers: 1) research papers, 2) reports on case studies, 3) reports on major design and process projects, 4) design and process standards and proposals, 5) literature review, and 6) discussion and position papers that discuss the works published in the journal or present retrospections on critical and strategic issues in the transdisciplinary design and process science.
Abstract: Both process modelling and simulation play an important role in understanding healthcare processes. Since IDEF0 can effectively capture requirements and is relatively easy to communicate, combining IDEF0 with simulation provides a promising way to analyse processes dynamically and to assist in decision-making. This paper explores the feasibility of building an environment that can be used to simulate real IDEF0 models for healthcare processes. EXPRESS language is used to capture the required information that…would make an IDEF0 model capable of simulation. An example IDEF0 model simulator is developed in order to explore some of the issues in simulating healthcare processes. A prototype system structure for this simulator is provided in the paper. The healthcare process is used as an example application in this paper. An example IDEF0 model for "Identify Patient Safety Hazards" process represented by XML is loaded and simulated.

Abstract: The Internet service provider market is very competitive. Small and medium-size Internet service providers (ISPs) are competing for customers, while, at the same time, they are under price pressure from upstream providers. Therefore, these ISPs have to reduce their overall cost of interconnection. In order to address this issue, Internet exchange points (IXPs) have been built up in recent years, which allow small and medium-size ISPs to go into public or private peering with other ISPs.…However, those ISPs do not have sufficient information to select the optimal set of ISPs, with which they should go into private peering agreements. In this paper, we describe an approach, which provides ISPs with the information about the most economical interconnections to other ISPs. This approach helps small and medium-size Internet service providers to reduce their interconnection costs for upstream connectivity and to improve network performance for their customers. To achieve that, our approach uses Internet topology information in close neighborhood of the ISP (which is determined by the set of ISPs connected to the IXP), measurement information about the number of bytes transmitted, and traffic pricing schemes. Based on real data, our analysis results demonstrate that our approach provides the necessary information to ISPs for locally optimizing their interconnection agreements (e.g. peering, sibling, transit agreements).

Abstract: The domain expert's heuristics in the performance design and improvement of collaborative systems are systematized as Qualitative rules. A knowledge base system built by using the Qualitative rules diagnoses the bottlenecks in the system operation and suggests improvements or tuning. However, the bottlenecks cannot be completely resolved due to the constraints imposed on the system resources. In such a case, our strategy is to resolve the local bottlenecks, while maintaining the global stability of the system.…To enforce this strategy, we demarcate the system model into local, upstream and downstream sections, and set up the Qualitative improvement rules for each of these sections. A performance improvement task is then guided by a set of local, forward propagation, backward propagation and global rules. Local rules correspond to a local improvement. When the local rules fail to yield satisfactory results, the backward propagation rules are called upon to indicate the improvements to be made in the upstream of the network so as to resolve the problematic local bottleneck. The forward propagation rules estimate the effects on the downstream of the network due to the resolution of the chosen bottleneck. Finally, the advisability of resolving a local bottleneck, while keeping the global adverse effects to a minimum, is given by the global rules.

Abstract: Eliminating an off-diagonal term from a design matrix brings value in a few different contexts. For a coupled design, it can decouple the design matrix. For a decoupled design, it will increase the flexibility of design interaction structure and thereby reducing the imaginary complexity. While eliminating an off-diagonal term is always preferred in the Axiomatic Design framework, the cost and benefit of eliminating it must be balanced to justify the effort. Assuming the cost is proportional…to the number of off-diagonal terms to eliminate, this paper presents methods to identify a minimum set of off-diagonal terms that achieve the two objectives – decoupling and imaginary complexity. For the decoupling problem, the cycle matrix, C, provides an effective means to identify the optimal set of off-diagonal terms. The method we presented for the coupling problem guarantees the optimal solution. For the imaginary complexity problem, we presented a heuristic approach as a preliminary result to developing a complete method to select the optimal set.

Abstract: Development processes in chemical engineering are hard to support. In particular, interorganizational development processes are concerned with the coordination of activities carried out by engineering teams distributed across several cooperating organizations. The management system AHEAD is based on long-term experience gathered in multiple application domains (software, mechanical, or chemical engineering). AHEAD supports the management of dynamic interorganizational development processes by dynamic process views which allow the partial visibility management of processes for…external organizations. AHEAD provides support for evolving process views which are able to reflect the changes in evolving development processes. Process views serve as the basis for inter-process connection. Processes can be split top-down into subprocesses for different organizations or composed bottom-up for pre-existing processes from different organizations. When mixing top-down and bottom-up process, planning and execution is possible. AHEAD allows process managers to monitor and control their intra-organizational development processes with all inter-organizational connections to processes in cooperating organizations in a uniform modeling language.

Abstract: Iterative life cycle models have become popular in software engineering, e.g. in agile development. In contrast, the waterfall model appears to prevail in manufacturing engineering disciplines. This includes aircraft engineering and Boeing's project for developing its most recent passenger aircraft, the 777. The paper walks through the phases of the 777's development and compares this process to iterative development. The comparison suggests two observations: Firstly, the over-all waterfall approach in the 777…project appears to be well-motivated by the physical, manufactured nature of aircraft components such as wings, in addition to safety concerns. Secondly, several iterative elements in the development of the 777 can also be identified. A major source of these is digitalization of development, in particular the use of CAD tools for a process called digital preassembly.
