The categorization of simulation into live, virtual, and constructive is problematic, because there is no clear division between these categories. The degree of human participation in the simulation is infinitely variable, as is the degree of equipment realism. This categorization of simulations also suffers by excluding a category for simulated people working real equipment (e.g., smart vehicles).
Udidi lwemfaniso ephilayo, yokwenene, kwaye ulwakhiwo luyingxaki, ngenxa yokuba akukho lwahlulo lucacileyo phakathi kwezi ndidi. Iqondo lwentatho-nxaxheba yomntu kwimfaniso lilutshintsho elingapheliyo, nanjengoko iliqondo lesixhobo sokwenene. Oku kuhlelwa kweemfaniso kwakhona kuyasilela ngokukhuphela ngaphandle udidi lwemfaniso yabantu abasebenza ngezixhobo zokwenene (umz. izithuthi ezintle).
