Claim 15:
16. A device comprising:
at least one processor;
and at least one memory including computer program code;
the at least one memory and the computer program code configured to, with the at least one processor, cause the device to:
specify a topological structure of a physical system in space-time;
construct a qualitative spatio-temporal model of the physical system, wherein the qualitative spatio-temporal model of the physical system is expressed by topological semantics based on a Tonti diagram in which qualitative states of physical variable are systematically organized as nodes on the Tonti diagram and governing expressions constraining the qualitative states are symbolically expressed as connections between selected nodes on the Tonti diagram;
use at least one of fully or partially provided quantitative information of the qualitative spatio-temporal model of the physical system to instantiate the qualitative spatio-temporal model of the physical system into at least one of a quantitative or hybrid model, wherein the hybrid model is a combination of a qualitative and quantitative model; and
using both the topological structure and the qualitative spatio-temporal model, simulate the qualitative spatio-temporal behaviors of the physical system as a discrete set of state transitions in space-time to produce a simulation of the physical system.
