One of the problems of systems based on distributed architectures is the communication between applications running on different platforms on a network. The appearance of middleware reduces the complexity in transferring data between heterogeneous platforms of such systems. Up until now, various middleware have been proposed to facilitate the distributed system construction. In the context of c...

This article describes an integrated design of Computer Supported Learning Environments (CSLE) and Workflow Management Systems (WfMS). Fundamental approaches for the integration are pointed out by extending the traditional Build-time modeling perspectives of WfMS. The use of an integrated environment and its synergy effects result in a substantial improvement of the educational level, the day-t...

DIORAMA system which is using rapid information collection and accurate resource tracking can assist incident commanders in their attempt to bring order to the chaos as they direct rescue operations for Mass Casualty Incidents (MCI). This system makes use of active Radio Frequency Identification (RFID) tags to identify the location and status of the patients and responders involved in a MCI. Th...

The concept of “curved perspective” has been used by artists such as M.C. Escher in order effectively convey a sense of three dimensional space while being restricted to a two dimensional canvas. We present an interactive system to create and manipulate projections with a curvilinear perspective. Our system presents the user with a set of intuitive screen-space perspective primitives that contr...

The relationship between supply chain resilience and environmental sustainability (greening) has been a topic of peripheral discussion in the research literature. The aim in this paper is to investigate, from a supply chain modeling perspective, the extent to which supply chain greening and resilience strategies are supportive of each other. A strategic supply chain design model is introduced t...

Studies have shown that random order crossover helps reduces the risk of an out-of-stock event when an order that was issued later arrives earlier to offset the late arrival of an order issued earlier. The current school of thought is that, although such crossovers create complexities from a modeling perspective, they are surprisingly beneficial in practice since they decrease the realized lead...

abstract background: well-being is a subjective concept and means different things to various people. most of the research investigating the experience has concentrated on its problematic and pathological aspects. the aim of this research was to enhance the understanding of the contextual meaning of well-being based on personal life experiences of the participants. this will be of help to exper...

An approach using component technology for the development of System Dynamics models is introduced. At first a brief introduction of System Dynamics, its modeling perspective and its modeling elements is given. The representation of System Dynamics models in Vensim, an interactive software environment for the handling of such models, is described. On this basis the paper provides an approach fo...

When evaluating and developing organisations, the business process perspective is a popular one to use. Several methods exist and there are new ones being developed. When evaluating and/or developing organisations from a business process perspective, there is a need to reconstruct existing business processes. We have experienced problems in distinguishing and delimiting business processes in re...
