Information in healthcare: science, system, or service? (Powerpoint)

An abstract of the keynote presentation will be provided soon.

Short Bio

Professor Terry Young joined Brunel as Professor of Healthcare Systems after a 16.5 year career in industry, which started in broadband research and led in the end to healthcare strategy. His initial research, after a PhD in laser spectroscopy, lay in finite element modelling of photonic devices and optical circuits. Later, with project and line management, his experience broadened to include business development and corporate technology strategy, mainly in healthcare.
In 2001 he joined Brunel University and he has focused on healthcare since then, winning more than £13M in Research Council grants. The largest of these, MATCH, involves three other universities (Birmingham, Nottingham and Ulster) and looks at the value of technology to care delivery. Another recent project, RIGHT, involved four other universities (Cambridge, Cardiff, Southampton and Ulster) and explored the use of simulation and modelling in service provision.
His recent publications address healthcare delivery in terms of services, systems and technology, including commercial and investment decisions, uptake and adoption.

RFID Implementation: Recent Research and Opportunities (Powerpoint)

Organizations around the world are exploring the potential of RFID technologies. The additional visibility provided by RFID tags can assist in improving inventory accuracy, scheduling production, and retail store activities among a whole host of applications. However, the costs of RFID technologies can sometimes make it difficult to justify such actions. Our research team has investigated the potential of RFID in several settings: inventory management, retail marketing, job shop scheduling, lean manufacturing, distribution centers, and cold supply chain. We employ several research methodologies: simulation, systems dynamics, real options theory, empirical analysis of real data, and delphi studies of experts. In, this presentation we review several of these research projects to provide a comprehensive framework of recent RFID research and discuss opportunities for further research.

Business Process Simulation Revisited (PowerPoint Slides)

Although simulation is typically considered as relevant and highly applicable, in reality the use of simulation is limited. Many organizations have tried to use simulation to analyze their business processes at some stage. However, few are using simulation in a structured and effective manner. This may be caused by a lack of training and limitations of existing tools, but in this talk we will argue that there are also several additional and more fundamental problems. First of all, the focus is mainly on design while managers would also like to use simulation for operational decision making (solving the concrete problem at hand rather than some abstract future problem). Second, there is limited support for using existing artifacts such as historic data and workflow schemas. Third, the behavior of resources is modeled in a rather naive manner. This keynote will discuss these problems and show solutions that are based on using process mining results and improved modeling of resources. By incorporating better resource characterizations in contemporary tools, business process simulation can finally deliver on its outstanding promise.

A Life Cycle for Modeling and Simulations

Conducting a successful Modeling and Simulation (M&S) project poses significant challenges for engineers, analysts, managers, stakeholders, and sponsors. The use of an effective life cycle is critically important to meet the challenges. This keynote speech presents a comprehensive M&S life cycle created by the speaker. The M&S life cycle describes the blueprint (detailed plan or program of action) of an M&S application during its lifetime (from birth to retirement), and provides structured guidance to an M&S developer (engineer), analyst, manager, organization, and community of interest. The M&S life cycle specifies the work products to be created under the designated processes together with the integrated verification and validation and quality assurance activities. The M&S life cycle is critically needed to modularize and structure the M&S development and provide valuable guidance for project management. The M&S life cycle also identifies areas of expertise in which to employ qualified people. This keynote speech identifies which process to execute first to start an M&S project, which processes to execute one after the other, and which work products to produce one after the other throughout the entire life cycle until the project is successfully completed. The knowledge of such a comprehensive M&S life cycle is crucially needed to be able to conduct a successful M&S project.

On the Nature of Business Rules

Business rules are in the center of attention, both in the 'business world' and in the 'ICT applications world'. Recently, the OMG has completed a major study in defining the notion of business rule and its associated notions. On closer look, however, the definitions provided appear to be not as rigid and precise as one would hope and as deemed necessary. Based on the consistent and coherent theoretical framework of Enterprise Ontology, several clarifications of the core notions regarding business rules are presented. They are illustrated by means of a small example case.
