This paper proposes a complex systems approach to understand the growth and decline of Digital Businesses. Digital Businesses are characterised by unique factors such as a highly networked online customer base, where word of mouth spreads very fast, and minimal cost of incremental users due to economies of scale. Thus online businesses peak and plummet rapidly making it difficult to fathom their success...
Most modeling and simulation actions performed during hip arthroplasty studies, usually involve a static approach of the implant so that it fits the anthropometric measurements of the patient and meets the equilibrium conditions. Question is what will happen during motion. This can be done by using an interactive and dynamic software, like Anybody Modeling System. A dynamic approach will dramatically...
Software Product Lines (SPL) offer the ability to create, maintain and evolve a set of similar products with the simplicity of a single system rather than the complexity of deploying a multitude of products. It is well recognized by the research community interested in SPLs that designing SPLs with the standard UML language do not provide for a clear understanding of the SPL. This motivated us to...
Analysis method and computational solutions for thermo-and electrostatics effects of slender bodies often using multi-scale modeling, molecular dynamic simulation and data visualization technique. In the present work, we conduct a review of applying analytical methods such as BEM and FEM and molecular dynamics and computational methodologies to model the thermal and electrostatics effects on the slender...
There are a lot of data about biodiversity stored in different database models and most of them are relational. Recent research shows the importance of links and network analysis to discover knowledge in existing data. However, the relational model was not designed to address problems in which the links between data have the same importance as the data -- a common scenario in the biodiversity area...
Modern software systems are becoming more and more complex thus demanding for new powerful development mechanisms. Model-driven engineering has been recognised as a promising paradigm for the development of complex systems especially for its capability of abstracting the problem through models and then manipulating them to reach the implementation. In this work we provide a solution for the problem...
When software architectures are modeled from different view-points using different notations, it is necessary to keep information that appears in several models consistent. To achieve consistency for a specific system, developers need two competences: First, they have to be able to express the conceptual relationships between the elements of the involved modeling languages and domains. Second, they...
This paper studied the modeling and simulation of the public opinion propagation in the small-world network. The public opinion information propagation characteristics were firstly analyzed, and different states of the people in the propagation environment were proposed. Based on that, this paper constructed the public opinion propagation model based on the agent modeling method, and proposed the...
Platform as a Service (PaaS) solutions are changing the way software is produced, distributed, used, and priced. However, there has been little research into understanding the dynamics of PaaS business models and how these business models should be designed to establish a flourishing ecosystem around these platforms. Using design science research (DSR) we first identified the main design elements...
Due to environmental and ecological responsibility, enterprises are trying to reuse, remanufacture and recycle used products to reduce the negative impact on the environment. Reverse logistics is one of essential elements to implement such sustainable supply chain system. This paper proposes methodologies of simulation modeling and analysis of supply chain systems with reverse logistics flows. This...
The design process of Cyber-Physical Systems normally starts with the creation of funcional models that will be used for simulation purposes. However, most of the time such models are not directly reused for the design of the software architecture of the target embedded system. The present paper aims to fulfill this gap by introducing a novel mechanism called Assisted Transformation of models (AST)...
This paper focuses on the creation of a methodology for automatic real world adequate geosimulation model preparation, based on GIS models and statistical data collected. The urban environment is a network that exists among different structures, links, flows and relationships. The spatial distribution and development direction of the territory, also business environment development is determined by...
This paper describes an analysis framework for estimating the effects of Diplomatic, Informational, Military, and Economic (DIME) activities in the context of a theater of operations. We evaluate and recommend a set of candidate models of the flow and evolution of population beliefs and intentions as the starting point for developing a DIME Effects Modeling System (DEMS) for tactical commanders. We...
In a model-driven engineering development process that focuses on guaranteeing that extra-functional concerns modeled at design level are preserved at platform execution level, the task of automated code generation must produce artifacts that enable back-annotation activities. In fact when the target platform code has been generated, quality attributes of the system are evaluated by appropriate code...
One of the important benefits of model-to-model transformation is that it allows architects to design iteratively by analyzing and studying alternative or optimal solutions without redesign of the software architecture models or quality analytic models. The main contribution of this work is the presentation of five recently approaches based on the definition of a framework which applies separation...
A design method for integrated modeling and assessment DSS in Hydroinformatics based on ontology and domain modeling is given. Four levels of design are discussed. First, formal concept analysis is employed for domain ontology analysis and construction in Hydroinformatics. Second, OWL is used as representation language for domain ontology. In third level, metamodel method of domain model is combined...
The Disaster Response Network Enabled Platform (DRNEP) is a system that integrates a set of independently developed infrastructure and disaster simulators. This paper describes some of the architectural choices that we made for DRNEP. The overall system uses a master-slave pattern, with one master simulator orchestrating all of the others, based on a central system clock. As the various simulators...
Construction of the virtual creature using computer hardware and software is an important aspect in computer simulation of life sciences. The paper provides a brief introduction of Object-oriented Biological modeling which used as a design methodology. The advantage of this method is a well consideration of specific purpose of building a model, that is to say, the user's needs.
The developed model for analysis of MEMS structures based on inhibited Petri Nets is presented. Results of analysis are presented. Approaches to development of software for information technology of MEMS analysis and synthesis are offered.
We present a modular evolutionary framework, coined CASE for "complex adaptive system evolver", to automate the modeling and analysis of agent-based simulations (ABSs). The field of agent-based modeling is rapidly growing due to its capabilities to expose the emerging complex phenomena occurring in a wide range of natural and artificial systems such as biological cells, societies, battlefields,...
