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...

This paper describes work in progress to enhance the performance of the Ground Processing Scheduling System (GPSS). The GPSS is a constraint-based scheduler that deals with three kinds of constraints: temporal, resource, and connguration. It starts with a complete schedule that may have some constraint violations (connicts) and gradually improves the schedule by reducing the violations. The obj...

The integration of discrete event simulation methods into Scientiic and Technical Computing Environments (SCEs) extends their functionality and opens new ways for a convenient interactive modelling and simulation. Because of the wide range of algorithms provided by SCEs, it also ooers lots of possibilities for solving complex problems with simulations in an uniform environment. The paper discus...

This paper gives an overview of some of the factors that determine the efficiency of differently implemented wait statements. The purpose is to give some guidance to simulation modelers as to what system to choose and, for the chosen system, what wait constructs to use in order to make program execution efficient. It is also aimed at informing constructors of simulation software about what issu...

This work aims the functionalization of reduced graphene oxide nanoplatelets with chitosan (G-chitosan) and also with poly(styrenesulfonic acid) (GPSS), thus forming stable, dispersed aqueous solutions. G-chitosan and GPSS solutions allowed the layer-by-layer (LbL) film formation with glucose oxidase (GOx), establishing multilayered nanostructures with elevated control in thickness and morpholo...

INTRODUCTION Patient-reported outcome measures (PROs) specific for genital psoriasis (GenPs) have not been described. METHODS In this cross-sectional, qualitative study in patients with moderate-to-severe GenPs, we sought to develop a PRO useful for GenPs symptom assessment. A literature review was performed to identify relevant psoriasis or GenPs symptoms and existing PROs that may be useful...

The purpose of this study was to develop and evaluate the initial reliability, validity and classification accuracy of a new brief screen for adolescent problem gambling. The three-item Brief Adolescent Gambling Screen (BAGS) was derived from the nine-item Gambling Problem Severity Subscale (GPSS) of the Canadian Adolescent Gambling Inventory (CAGI) using a secondary analysis of existing CAGI d...

This paper provides simulation practitioners and consumers with a grounding in how discrete-event simulation software works. Topics include discrete-event systems; entities, resources, control elements and operations; simulation runs; entity states; entity lists; and entity-list management. The implementation of these generic ideas in AutoMod, SLX, and Extend is described. The paper concludes w...
