Successful management of a software project, besides a well-defined project development process, requires an early estimate of project complexity. In a prevailing practice, software development costs usually have been determined a posteriori i.e. after software project implementation. It is essential, however, to know this estimate a priori, i.e., before commencement of works. This paper presen...

Making use of the concepts of the activity diagrams of the Unified Modeling Language, this paper defines an important class of workflows, called flow independent workflows, which are deterministic in the sense that if a flow independent workflow is given the same multi-set of resources as input over and over again, it will produce the same output every time. After which, this paper provides a m...

This paper describes a new approach to modelling enterprise architectures. By viewing enterprise models as metaphors and then linking these metaphors, in a structured way, to ontologies, we propose that unified languages can be developed to describe a wide variety of enterprise structures. This overcomes a serious shortcoming with contemporary approaches to enterprise modelling. This approach i...

Today the most organizations (e.g. banks and insurance institutes) consist of the various units which under the control of the main organization (unified management) act independently. Sometimes the manager presents some services which incur costs such as advertisement and introducing a new technology. Most organizations consist of several individual units. Resource allocation issue appe...

We provide the unified methodology for searching for approximate decision reducts based on rough membership distributions. Presented study generalizes well known relationships between rough set reducts and boolean prime implicants.

Numerous methodologies for developing agent-based systems have been proposed in the literature. This proliferation creates a challenge to practitioners who need to select a methodology to adopt. This situation is analogous to that of object-oriented methodologies and notations pre-UML, and we argue that the time is ripe to begin the development of a next generation agent-oriented software engin...

We describe a scalable and unified architecture for a Montgomery multiplication module which operates in both types of finite fields GF (p) and GF (2). The unified architecture requires only slightly more area than that of the multiplier architecture for the field GF (p). The multiplier is scalable, which means that a fixed-area multiplication module can handle operands of any size, and also, t...
