The growing number of installed photovoltaic plants is making the possibility of simulating their behavior and effects on the power network more and more relevant. In this context an accurate yet simple model of the panels is necessary for the evaluation of the power production as well as of the system efficiency in off-line and on-line simulation. In the preliminary stages of large plant design,...
This paper deals with the use of computer simulation with the aim of design efficient production in manufacturing and production systems. In our case, the possibilities of such use are demonstrated on particular example from industrial practice. The purpose was to build up a model of the prepared manufacture system and, especially, to propose a solution designed to increase productivity and to find...
Under the guidance of the theories of Complex Adaptive System and Artificial Societies, modeling and simulation of international politics evolution in crisis was studied. The Model of International Politics Evolution (IPEM) in crisis based on Agent was built. The function and architecture of IPEM were introduced. Individual Agent, including Nation Agent, International Organization Agent and Environment...
As the environment of manufacturing enterprises is becoming more complex and dynamic this requires powerful tools for the support of decisions in manufacturing and production planning. Simulation as one of those tools has been widely applied in manufacturing and logistics. However, the models used for simulation are incomplete because the human factor in terms of its decision making and behaviour...
The theory of connection has been used to solve many problems in engineering. economics, and in management; in this paper, firstly, the theory of connection is introduced. Secondly, a new toolbox of functions for modeling and simulation is presented. Thirdly, the theory is used to solve a planning and scheduling problem with the help of the toolbox of functions. The scope of this paper is limited...
The fruit setting patterns (fruit number per node and arrangement within the node) along the individual headed fruit-bearing shoot of 10-year-old peach tree (Prunus persica (L.) Batsch) were studied over two successive years (2005-2006) in Beijing, China. The headed fruit-bearing shoot, which described as a succession of nodes which produced fruit, is modeled by a Markov chain. This model includes...
Developing sustainable urban environments is complex as it requires consideration of interacting social, economic and environmental sustain ability factors. The task is made even more difficult by the wide variety of stakeholders (e.g. planners, architects, businesses and the public) that may be involved in the process and the lack of a common language for all to understand. This paper describes a...
