This paper shows how agent-based modelling technique is a suitable approach for social scientists to model complex adaptive systems, using computer as experimental environment. Unfortunately advanced tools are lacking as well as an unified language supporting its development. We present JAS, a new agent-based simulation tool, developed with the aim to improve AB models designing. We give a brief methodological introduction to its use and a short description of its architecture.

This paper deals with the problem of patient boarding in Emergency Department (ED) due to the lack of availability of stay beds in inpatient hospital wards. The boarding of emergent patients is a major reason of ED overcrowding, which in turn creates long waiting times in ED, as well as patient and staff dissatisfaction. In this paper a hybrid simulation framework is proposed to describe how emergent and elective patients flows interact each other inside the hospital. The framework combines System Dynamics (SD) and Discrete Event Simulation (DES). Flows are generated at macro level by the SD model, while in DES model they are disentangled into single entities following a detailed process-oriented pathway. The hybrid model has been then applied and validated to data from a medium-size public hospital located in Genova (Italy). Furthermore, some metrics (such as waiting times to be admitted in hospital, number of trolleys in ED, inpatient bed occupancy rates and elective patients delayed) are proposed as key indicators to assess the system performance.

Traditional (i.e. analytical) modelling practices in the social sciences rely on a very well established, although implicit, methodological protocol, both with respect to the way models are presented and to the kinds of analysis that are performed. Unfortunately, computer-simulated models often lack such a reference to an accepted methodological standard. This is one of the main reasons for the scepticism among mainstream social scientists that results in low acceptance of papers with agent-based methodology in the top journals. We identify some methodological pitfalls that, according to us, are common in papers employing agent-based simulations, and propose appropriate solutions. We discuss each issue with reference to a general characterization of dynamic micro models, which encompasses both analytical and simulation models. In the way, we also clarify some confusing terminology. We then propose a three-stage process that could lead to the establishment of methodological standards...

We present JAS 2, a new Java platform which aims at providing a unique simulation tool for discrete-event simulations, including agent-based and dynamic microsimulation models. JAS 2 is not released as a self-contained stand-alone application for model development. With the aim to develop large-scale, computationally resource-intensive models, the main architectural choice of JAS 2 is to use whenever possible standard, open-source tools aready available in the software development community. This decision entails a longer learning curve for the user than a dedicated, language-specific software package, but it allows for a more professional approach to simulation modeling compared to specific proprietary environments. There are two main advantages of using an open architecture where external libraries can be added and utilized: one is the possibility to easily integrate external functions that can be added as plug-ins; the other is the possibility to freely extend and modify the func...

In this paper we propose a general framework for web-enabling economic and financial simulations. Especially suited for agent-based models, the system is fully build upon Open Source software and well-known standards which ensure a very high level of generality. For the sake of completeness, two tools are used to make an instance of this framework: JAS Library as a simulation
