This paper develops the theoretical and methodological relationship between multiobjective decision trees (MODT) and the multiobjective risk impact analysis method (MRIAM)—two tools that are useful in decision-making at each step of the system life cycle. Decision trees have been extensively used in decision problems with great success. Multiobjective decision trees include multiple noncommensu...

Traditionally, healthcare information systems have focused on the support of predictable and repetitive clinical processes. Even though the latter can be often prespecified in formal process models, process flexibility in terms of dynamic adaptability is indispensable to cope with exceptions and unforeseen situations. Flexibility is further required to accommodate the need for evolving healthca...

In decision support systems, it is essential to get a candidate solution fast, even if it means resorting to an approximation. This constraint introduces a scalability requirement with regard to the kind of heuristics which can be used in such systems. As execution time is bounded, these algorithms need to give better results and scale up with additional computing resources instead of additiona...

Doktorsavhandling vid Chalmers tekniska högskola Ny serie nr. 3765 Cover: The cover illustration graphically portrays the philosophy of Systems Theory. It shows a system of systems with input and several outputs, controls and mechanisms, and how it all inevetably affect each other. It portrays both the solutions and problems adressed in this thesis. Abstract Product development companies strive...

Hyperdocuments present special requirements for integration with lifecycle and versioning systems. These requirements can best be summarized as "versioned linking", something not addressed by merely versioning the storage objects involved. The overriding challenge in versioned linking is resolving the correct version at the end of a link -where "correct" is defined by arbitrary business policy....

The primary role of component-based software engineering is to address the development of systems as an assembly of parts (components), the development of parts as reusable entities, and the maintenance and upgrading of systems by customising and replacing such parts. This requires established methodologies and tool support covering the entire component and system lifecycle including technologi...

Lately the notion of capability has emerged in information system engineering as the means to support development of context dependent organizational solutions and supporting IT applications. To this end a Capability Driven Development (CDD) approach has been proposed. As key part of CDD is the concept of patterns that is used to support the capability design from existing solutions as well as ...

The Architecture Analysis & Design Language, (AADL), Society of Automotive Engineers (SAE), AS5506, was developed to support quantitative analysis of the runtime architecture of the embedded software system in computer systems with multiple critical operational properties, such as responsiveness, safety-criticality, security, and reliability by allowing a model of the system to be annotated wit...

Enterprises are focusing more and more on knowledge issues for global product development. This paper describes knowledge evolution processes in product development activities and proposes a knowledge evaluation method in product lifecycle design. The paper also theoretically analyzes the evaluation model and illustrates how knowledge values can be assessed by case study. The case study shows h...

Lifecycle information like e.g. relations resulting from re-use of Learning Resources and knowledge documents can be utilized to support search, retrieval and authoring of Learning Resources. We describe challenges that have to be faced when capturing lifecycle information in proprietary office applications like PowerPoint and show how we solved them in the implementation of ReCap.KOM add-ins f...
