This paper presents a methodology for structuring families of models expressed at multiple levels of resolution and integrating them into a coherent whole. The importance of such structuring for model reusability and interoperability has been well discussed by Davis [5]. Thismultiresolution methodology was demonstrated in a prototype application to a family of models from the US Army CECOM libr...

This paper is the result of a reeexion coming from the usage and learning of the language B. It tries to better explain and understand the assembly primitives includes and uses of the language. It presents a high-level notion of components and develops a \component algebra". This algebra is specialized to deal with the B-components. The B assembly primitives are re-expressed in this basic forma...

This paper uses a case study of a multi-disciplinary colorectal cancer team in health care to explain how a model of performance measures can lead to debate and action in Soft System Methodology (SSM). This study gives a greater emphasis and role to the performance measures than currently given in typical SSM studies. Currently the concept of performance measurement in SSM is in the form of a s...

In this paper I show that it is possible to use Regge theory to constrain the initial parton distribution functions of a global DGLAP fit. In this approach, both quarks and gluons have the same high-energy behaviour which may also be used to describe soft interactions. More precisely, I show that, if we parametrise the parton distributions with a triple-pole pomeron, i.e. like log 2 (1/x) at sm...

A theory of complex systems has been developed from the forties, relating simple elementary processes to collective functional properties in physics, biology and the social sciences. More recently, application to design and business have been developed. A major turning point around year 2000 is the availability of huge set of data which complex systems methodology allows to transform into usefu...

This paper describes the application of Bayesian theory to the problem of compensating for soft tissue deformation to improve the accuracy of imageguided surgery. A triangular surface mesh segmented from a pre-operative image is used as the input to the algorithm, and intra-operatively acquired ultrasound data compounded into a 3-D volume is used to guide the deformation process. Prior probabil...

The aim of this article is to lay a foundation for providing a soft algebraic tool in considering many problems that contain uncertainties. In order to provide these soft algebraic structures, the notion of union soft q-ideals are introduced, and related properties are investigated. Conditions for a union soft ideal to be a union soft q-ideal are established. Characterizations of a union soft q...

In this article, we use soft systems methodology and complexity modeling to build an evaluation approach of a data warehouse implemented in a leading European financial institution. This approach consists in building a theoretical model to be used as a purposeful observation lens, producing a clear picture of the problematic situation under study and aimed at providing knowledge to prescribe co...
