However, it can be quite difficult to format shapefiles in a way that a modeler could easily apply or use within the AnyLogic framework for GIS-based simulations. The shapefile format includes vector data representing location, shape, and attributes of geographic features such as lakes, mountains, buildings, and roads. Within GIS, Esri shapefiles are the most commonly used. In addition to more traditional simulation, AnyLogic also has relatively recent support for geographic information system (GIS) simulation and modelling. To the best of our knowledge, there is only one active user community in LinkedIn for the AnyLogic modelling software. In their respective ABM, birds are grouped into roost agents whose moving behavior is modelled with particle systems proposed by Reeves, wherein birds’ flight speed and home range are crucial model parameters.Īlthough AnyLogic is a powerful multi-paradigm modelling framework, there are few user group resources or forums available for its users. Two bird-biting species of Culex pipiens and Culex restuans, and two general groups of birds (ie, American crows and the remainder, competent species) were considered within this ABM. Another ABM with no human component was proposed by Bouden et al for southern Quebec, Canada. Three possible bird species of black-capped chickadee, blue jay, and American crow were considered within this ABM. In the WNV literature, an ABM was proposed by Li et al for an area of 165 km 2in Cook County, Illinois, which was modelled as a raster map. To date, the use of ABMs in the WNV literature has been rather scant, even though it has been extensively employed in many different health care applications. In this context, ABMs could be deployed to incorporate biodiversity of birds and mosquitoes as completely as possible, along with their interactions with humans. Bowman et al proposed a single-season DE model of WNV transmission dynamics in a mosquito-bird-human population. Wonham et al developed a single-season susceptible-infectious-removed DE model for WNV transmission in a bird-mosquito population. Thomas and Urena formulated a difference equation for WNV evolution in a mosquito-bird-human community with a focus on mitigation via pesticide. Most notably, differential equation (DE) models have been utilized to model disease transmission dynamics. Various approaches to model WNV transmission risk or spread are reviewed in Chevalier et al. Many scientific studies have examined the transmission dynamic modelling of WNV. ![]() ![]() Conversely, various kinds of mammals (including humans) act as incidental or dead-end hosts that cannot pass the virus to another host or feeding mosquitoes. In this transmission cycle, birds act as amplifying hosts since the virus is amplified in their bloodstream, and it could be transmitted to the next group of feeding mosquitoes. An infected bird can, in turn, infect a (healthy) mosquito that bites the bird. An infected mosquito can infect a (healthy) bird by feeding on it. The main means of transmission and spread of WNV is through birds. During the next stages of the mosquito life-cycle, eggs hatch into larvae, and then begin molting their skins until they change into pupae that develop into adult mosquitoes. Under certain weather and habitat conditions, adult female mosquitoes take a blood meal from their hosts to obtain necessary nutrition to lay their eggs. Mosquitoes of certain genera carry and transmit WNV to other animals including humans. This paper examines data inputs into an agent-based model (ABM) and simulation of West Nile Virus (WNV) using the AnyLogic software, with a specific focus on data collection and compatibility, and preparation or processing techniques. ![]()
