Overview on agent-based social modelling and the use of formal languages

Transdisciplinary Models and Applications investigates a variety of programming languages used in validating and verifying models in order to assist in their eventual implementation. This book will explore different methods of evaluating and formalizing simulation models, enabling computer and industrial engineers, mathematicians, and students working with computer simulations to thoroughly understand the progression from simulation to product, improving the overall effectiveness of modeling systems.Postprint (author's final draft

Early aspects: aspect-oriented requirements engineering and architecture design

This paper reports on the third Early Aspects: Aspect-Oriented Requirements Engineering and Architecture Design Workshop, which has been held in Lancaster, UK, on March 21, 2004. The workshop included a presentation session and working sessions in which the particular topics on early aspects were discussed. The primary goal of the workshop was to focus on challenges to defining methodical software development processes for aspects from early on in the software life cycle and explore the potential of proposed methods and techniques to scale up to industrial applications

Characterization and Modeling of Spectrum Trading Markets

Telecommunication regulators are facing increasing pressure to make spectrum resources more widely available to new wireless services and providers. In spectrum trading markets, buyers and sellers determine the assignments of spectrum and, possibly, its uses. These markets are being considered or implemented by the regulatory bodies of many countries as a way to provide increasing efficiency in the use of spectrum and attend the demand for this resource. This work describes a classification for the implementation of spectrum trading markets and a way to model them and identify the conditions for their viability. Specifically, we make use of Agent-Based Computational Economics (ACE) to model the participants in these markets, analyze the behaviors that emerge from the interactions of its participants and determine the conditions for viable markets. Our results, provide guidelines that can be used by regulators and wireless service providers for the design and implementation of these markets

An Agent-based approach to modelling integrated product teams undertaking a design activity.

The interactions between individual designers, within integrated product teams, and the nature of design tasks, all have a significant impact upon how well a design task can be performed, and hence the quality of the resultant product and the time in which it can be delivered. In this paper we describe an ongoing research project which aims to model integrated product teams through the use of multi-agent systems. We first describe the background and rationale for our work, and then present our initial computational model and results from the simulation of an integrated product team. The paper concludes with a discussion of how the model will evolve to improve the accuracy of the simulation

Measuring Sustainable Development: The Use of Computable General Equilibrium Models

This paper advocates computable general equilibrium models as a methodological tool that is particularly suitable for measuring the impacts of policy interference on the three dimensions of sustainable development, i.e. environmental quality, economic performance (gross efficiency) and equity. These dimensions are inherently intertwined and subject to trade-offs. Computable general equilibrium models can incorporate various important sustainable development indicators in a single consistent framework and allow for a systematic quantitative trade-off analysis. --computable general equilibrium modeling (CGE),sustainability impact assessment (SIA),sustainable development (SD)

Modeling the Internet of Things: a simulation perspective

This paper deals with the problem of properly simulating the Internet of Things (IoT). Simulating an IoT allows evaluating strategies that can be employed to deploy smart services over different kinds of territories. However, the heterogeneity of scenarios seriously complicates this task. This imposes the use of sophisticated modeling and simulation techniques. We discuss novel approaches for the provision of scalable simulation scenarios, that enable the real-time execution of massively populated IoT environments. Attention is given to novel hybrid and multi-level simulation techniques that, when combined with agent-based, adaptive Parallel and Distributed Simulation (PADS) approaches, can provide means to perform highly detailed simulations on demand. To support this claim, we detail a use case concerned with the simulation of vehicular transportation systems.Comment: Proceedings of the IEEE 2017 International Conference on High Performance Computing and Simulation (HPCS 2017

Adaptive Agent Modeling as a Tool for Trade and Development Theory

This paper makes use of an adaptive agent framework to extend traditional models of comparative advantage in international trade, illustrating several cases which make theoretical room for industrial policy and the regulation of trade. Using an agent based implementation of the Hecksher-Ohlin trade model, the paper confirms Samuelson’s 2004 result demonstrating that the principle of comparative advantage does not ensure that technological progress in one country benefits its trading partners. It goes on to demonstrate that the presence of increasing returns leads to a situation with multiple equilibra, where free market trading policies can not be relied on to deliver an outcome which is efficient or equitable, with first movers in development enjoying permanent advantage over later developing nations. Finally, the paper examines the impact of relaxation of the Ricardian assumption of capital immobility on the principle of comparative advantage. It finds that the dynamics of factor trade are radically different from the dynamics of trade in goods and that factor mobility converts a regime of comparative advantage into a regime of absolute advantage, thus obviating the reassuring equity results which stem from comparative advantage.Agent-based modeling; comparative advantage; increasing returns; international trade

Economics of irrigation water management : a literature survey with focus on partial and general equilibrium models

Water policy is an important topic on the agenda of the international community, and efficiency and equity in the allocation of water have emerged as important factors to be considered. Water pricing can be used to mitigate both the quantity and quality dimensions of water scarcity. This paper reviews partial equilibrium models and general equilibrium models that are relevant to irrigation water management issues. The most widely discussed issues in these models are water markets and water pricing. The interrelationships between economic, cultural, social, and political aspects that are related to water policy make it difficult to provide a comprehensive policy analysis. General equilibrium models of irrigation water management allow incorporation of both the irrigation sector and the other sectors in the economy and analysis of policies affecting each of them and the interaction between them. In addition to being able to address sector and household specifications, production factors, time horizon, pricing policies, and institutions such as water markets, general equilibrium models allow the analysis of the impact of water policies on equity and poverty alleviation. The authors conclude that, although there has been a significant increase in efforts to analyzewater related problems, analytical and empirical research in the field is still deficient and more effort is needed to address them.Environmental Economics&Policies,Water Supply and Sanitation Governance and Institutions,Town Water Supply and Sanitation,Water Supply and Systems,Water Conservation
