-This paper describes an integrated software environment for multi-modal public transit simulation based on the principles of geosimulation that integrates the capabilities of multi-agent systems, GIS and interactive visualization. The goal of the presented research is to explore possibilities of population in one of Latvia's planning regions, called Vidzeme, to access state/municipal and other services by using public transport. In order to achieve the defined goal, an integrated simulation environment for public transit analysis and planning is developed.
The research demonstrates the efficiency of the simulation technique application for the analysis of goldmine system operation with a particular focus on truck-shovel system. The research has been carried out within the modelling competition "IIE/Rockwell Student Simulation Competition" arranged by an international organization IIE (Industrial Engineering). The information on the goldmine system structure and operation has been provided by the competition organizers, thus allowing the authors of the article to analyse the system operation based on real data and to propose recommendations and solutions for increasing goldmine efficiency through the optimization of technical resources used. A simulation model of the goldmine system is developed by means of Arena simulation environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
