Reengineering Production Systems: the Royal Netherlands Naval Dockyard

Reengineering production systems in an attempt to meet tight cost, quality and leadtime standards has received considerable attention in the last decade. In this paper, we discuss the reengineering process at the Royal Netherlands Naval Dockyard. The process starts with a characterisation and a careful analysis of the production system and the set of objectives to be pursued. Next, a new production management structure is defined after which supporting planning and control systems are designed and a number of organisational changes are carried through. In this way, the Dockyard may combine high technological capabilities with an excellent logistic performance

Information technology in construction: How to realise the benefits?

Advancement in the utilisation of computers has, in recent years, become a major, even dominating research and development target in the architecture, engineering and construction industry. However, in empirical investigations, no major benefits accruingfrom construction IT have been found. Why do the many IT applications, which when separately analysed seem so well justified, fail to produce positive impacts when the totality of the construction project is analysed? The objective of this chapter is to find the explanation for this paradox and to provide initial guidelines as to what should be done to correct the situation

Collaborative information systems and business process design using simulation

The Information Systems (IS) community promotes the idea that IS analyst should have a clear understanding of the way the organization operates before attempting to propose an IS solution. It is argued that to take a complete advantage of the underlying Information Technology (IT), organizations should first identify any process flaw and then propose a suitable IT solution. Similarly, many process design approaches claim that Business Process (BP) design should be done considering the advantages provided and the limitations imposed by the underlying (IT). Despite this fact research in these domains provides little indication of which mechanisms or tools can help BP and IS analyst to understand the complex relationships amongst these two areas. This paper describes the insights gained during a UK funded research project, namely ASSESS-IT, that aimed to depict the dynamic relationships between IT and BP using simulation. One of the major limitations of the ASSESS-IT project is that it looked at relationship between BP and IT as a three layered structure, namely BP, IS and Computer Networks (CN), and did not explore in detail the relationships between BP and IS alone. This paper uses the outcomes derived from this project and suggests that, is some cases, the relationship between BP and IT could be analyzed by looking at the relationship between BP and IS alone. It then proposes an alternative simulation framework, namely BPISS, that provides the guideline to develop simulation models that portray BP and IS behavior performance measurements, offering in this way an alternative mechanism that can help BP and IS analyst to understand in more detail the dynamic interactions between BP and IS domains

Simulation for business processes and information systems design

Business Process (BP) literature promotes the value of business processes as essential gearwheels that help organizations to reach their goals. Similarly, many process design approaches claim that Information Technology (IT) is a major enabler of business process, a view also shared by the Information Systems (IS) community. Despite this, BP and IS approaches do not provide clear guidance on how to assess the benefits that a given IS design may bring to the BP prior the IS implementation. Nor is clear indication of which modeling techniques could be used to assess such relationship. This paper uses the insights gained during a UK funded research project, namely ASSESS-IT, that aimed to depict the dynamic relationships between BP and IT to propose an alternative framework to develop BP simulation models that depict the dynamic behavior of the relationships between BP and IS

Analysis of Software Binaries for Reengineering-Driven Product Line Architecture\^aAn Industrial Case Study

This paper describes a method for the recovering of software architectures from a set of similar (but unrelated) software products in binary form. One intention is to drive refactoring into software product lines and combine architecture recovery with run time binary analysis and existing clustering methods. Using our runtime binary analysis, we create graphs that capture the dependencies between different software parts. These are clustered into smaller component graphs, that group software parts with high interactions into larger entities. The component graphs serve as a basis for further software product line work. In this paper, we concentrate on the analysis part of the method and the graph clustering. We apply the graph clustering method to a real application in the context of automation / robot configuration software tools.Comment: In Proceedings FMSPLE 2015, arXiv:1504.0301

Analyzing the Effects of Tactical Dependence for Business Process Reengineering and Optimization

Implementing business and manufacturing process reengineering is challenging and poses major issues. The dependence issues between process functions during the implementation phase are the main reason for the high failure rate of process reengineering. The incompetence in identifying the dependence makes existing business process reengineering approaches static for modern business and manufacturing process structures. This paper has implemented a new process reengineering approach called the Khan–Hassan–Butt (KHB) methodology that incorporates the process interdependence algorithm to identify the dependence issues. The KHB method is a hybrid process reengineering approach to identify dependence issues before implementing changes; thus significantly reducing the failure rate of implementing business process reengineering. The KHB method has been implemented in a Bangladesh fabric manufacturing facility. The mapping and verification of the process have been completed using the WITNESS Horizon 22.5 simulation package. The case study has investigated the fabric production process and identified the dependence issues between each function and suggested changes to optimize the process. The outcome has shown significant improvement in production output and process efficienc

Re-Engineering, concurrent engineering, lean production: What is the ideal antidote for the construction industry's ailments?

It is widely agreed that the practice of construction is deficient and requires improvement. However, the construction research community has had little to contribute to a solution, except trialling new approaches from general management scene or advancing technological tools. It is argued that a new research frontier is needed, where integral understanding of operations, construction and computing is created. Through this understanding, real progress can be achieved

Principles in Patterns (PiP) : Evaluation of Impact on Business Processes

The innovation and development work conducted under the auspices of the Principles in Patterns (PiP) project is intended to explore and develop new technology-supported approaches to curriculum design, approval and review. An integral component of this innovation is the use of business process analysis and process change techniques - and their instantiation within the C-CAP system (Class and Course Approval Pilot) - in order to improve the efficacy of curriculum approval processes. Improvements to approval process responsiveness and overall process efficacy can assist institutions in better reviewing or updating curriculum designs to enhance pedagogy. Such improvements also assume a greater significance in a globalised HE environment, in which institutions must adapt or create curricula quickly in order to better reflect rapidly changing academic contexts, as well as better responding to the demands of employment marketplaces and the expectations of professional bodies. This is increasingly an issue for disciplines within the sciences and engineering, where new skills or knowledge need to be rapidly embedded in curricula as a response to emerging technological or environmental developments. All of the aforementioned must also be achieved while simultaneously maintaining high standards of academic quality, thus adding a further layer of complexity to the way in which HE institutions engage in "responsive curriculum design" and approval. This strand of the PiP evaluation therefore entails an analysis of the business process techniques used by PiP, their efficacy, and the impact of process changes on the curriculum approval process, as instantiated by C-CAP. More generally the evaluation is a contribution towards a wider understanding of technology-supported process improvement initiatives within curriculum approval and their potential to render such processes more transparent, efficient and effective. Partly owing to limitations in the data required to facilitate comparative analyses, this evaluation adopts a mixed approach, making use of qualitative and quantitative methods as well as theoretical techniques. These approaches combined enable a comparative evaluation of the curriculum approval process under the "new state" (i.e. using C-CAP) and under the "previous state". This report summarises the methodology used to enable comparative evaluation and presents an analysis and discussion of the results. As the report will explain, the impact of C-CAP and its ability to support improvements in process and document management has resulted in the resolution of numerous process failings. C-CAP has also demonstrated potential for improvements in approval process cycle time, process reliability, process visibility, process automation, process parallelism and a reduction in transition delays within the approval process, thus contributing to considerable process efficiencies; although it is acknowledged that enhancements and redesign may be required to take advantage of C-CAP's potential. Other aspects pertaining to C-CAP's impact on process change, improvements to document management and the curation of curriculum designs will also be discussed
