Basic Virtual Society

We first define a basic virtual society (BVS) as a set of populated and geo-referenced (located) households. Populated means that the households comprise the whole population of the country with its age and gender distributions in each voivodeship (data obtained from NCB). In other words, every individual from a population, described by its age and gender, is assigned to a particular household. Also, each household in the BVS has a geographic location assigned to it, or in other words, it is located. A schematic workflow for the generation of a basic virtual society is presented in Figure 1.

Fig.1: The workflow used to generate a basic virtual society. Data fr om NCB, i.e. number of households, age distribution of women and men, has a voivodeship resolution.

Once a basic virtual society is created, any additional infrastructural network can be developed using the same general workflow. First, specific outposts have to be located (in the lack of the geo-location data as in e.g. USA virtual society models of Ferguson et al[1] or Stroud et al[2] ). Then, agents have to be assigned to a particular outpost. Figure 2 presents a schematic workflow for the addition of schools and workplaces to the BVS.

Fig.2:The workflow used for the generation of the educational (schools) and employment (workplaces) infrastructure, and a subsequent assignment of agents to an appropriate institution. The numbers of different level schools, and the number of workplaces taken from NCB have a commune resolution. Primary and secondary schools, colleges, and workplaces are separated in the scheme because different methods were used for the populating of these institutions (see text).
