This paper reports the results of initial trials of a Group Process Support System (GPSS) to aid the training of Norwegian social services personnel in the use of a standardised framework known as Gerix, which is used for the assessment of social services clients. As well as providing the GPSS technology, a degree of structure was introduced to the groups involving feedback, debate, and re-asse...

In the General Position Subset Selection (GPSS) problem, the goal is to find the largest possible subset of a set of points, such that no three of its members are collinear. If sGPSS is the size the optimal solution, √ sGPSS is the current best guarantee for the size of the solution obtained using a polynomial time algorithm. In this paper we present an algorithm for GPSS to improve this bound ...

This research statement describes work in progress to enhance the performance of the Ground Processing Scheduling System (GPSS). The GPSS is a constraintbased scheduler that, using an anytime algorithm, deals with three kinds of constraints: temporal, resource, and configuration. It starts with a complete schedule that may have some constraint violations (conflicts) and gradually improves the s...

In order to investigate the effects of varying the rate of flow on endothelial integrity the rat isolated small intestinal vasculature was perfused at 1, 5, 10 or 20 ml/min with a gelatin-containing physiological salt solution (GPSS), followed by an injection of colloidal carbon suspension (CC). Significantly greater microvascular CC leakage occurred at 1 or 5 ml/min than at 10 or 20 ml/ mitt. ...

This paper discusses the benefits of combining metamodelling and graph transformations to automatically generate modelling tools for simulation formalisms. In metamodelling, formalisms are modelled in their own right at a meta-level within an appropriate meta-formalism. A meta-model processor uses this information to automatically generate tools to process –create, edit, check, optimize, transf...

Plain ATM (Asynchronous Transfer Mode) has poor performance in case of Data transmission. In order to improve its performance many Buffer Management Mechanisms have been proposed, e.g. push-out. The aim of this paper is to propose improved approach to push-out based on the analysis of various packet discard policies, and create a simulation model in GPSS (General Purpose Simulation System) in o...

We first note that block diagrams have been important for the learning of GPSS and have been used in most GPSS text books. The full value of block diagrams is obtained first when they can be automatically generated from program code and that block diagrams in turn can generate code. The computer generation of block diagrams requires, however, very exact rules for the block diagrams. This is lac...

This paper reviews efforts to design an environment for authoring group performance support system (GPSS) agents that can interact with remote internet resources, applications, and users. We review the architecture of the GPSS environment and show how its tutor/critic elements do and don’t map into an idealized specification extracted from the agent oriented programming and inter-agent communic...
