ABMs are considered particularly applicable to situations where interactions are local and potentially complex, where agents are heterogeneous, where the phenomenon has inherent temporal aspects, and where agents are adaptive –. Furthermore, ABM provides a natural description of a system that can be calibrated and validated by subject matter experts, and is flexible enough to be tuned to high degrees of sensitivity in agent behaviours and interactions. This emergent behaviour may be counterintuitive or a complex behavioural whole that is greater than the sum of its parts. The foundational premise and conceptual depth of ABM is that simple rules of individual behaviour will aggregate to illuminate or exhibit complex and emergent group-level phenomena that is not specifically encoded by the modeller. The modeller’s task is to determine which data sources best govern agent profiles in a given ABM simulation. their movements and their interactions with other agents. Agent properties may be conceived by the modeller or may be derived from actual data that reasonably describe agents’ behaviours – i.e. In the most general context, agents are both adaptive as well as autonomous decision-making entities who are able to assess their situation, make decisions, compete with one another on the basis of a set of rules, and adapt future behaviours on the basis of past interactions. Systems are modelled as a collection of agents (in this case, people) imbued with properties: characteristics, behaviours (actions), and interactions that attempt to capture actual properties of individuals.

Īgent based modelling is ‘bottom-up’ systems modelling from the perspective of constituent parts. Agent-based models have emerged in the past decades as a complementary approach to the long history of differential equation-based models that require a macroscopic perspective of the population of interest. As a preliminary application of the ABM methodology to STI spread, the focus of this work was to explore the inherent suitability and potential of the ABM method to this particular context.Īgent based modelling is becoming an effective tool in understanding infection spread and is particularly well suited to environments where the agents themselves and their interaction with one another are the principal vectors of infection spread. The objective of this work was to develop an agent-based model (ABM) to simulate the spread of sexually transmitted infections (STIs) within a population of interacting agents.

Individual and population-wide impacts were explored, with individual risk being impacted much more dramatically by population-level behaviour changes as compared to individual behaviour changes. The simulation results provide qualitative comparisons of STI mitigation strategies, including the impact of condom use, promiscuity, the form of the friend network, and mandatory STI testing.

Sixteen agent parameters interact individually and in combination to govern agent profiles and behaviours relative to infection probabilities. The model was developed in C++ using the Boost 1.47.0 libraries for the normal distribution and OpenGL for visualization. The work contrasts compartmentalized mathematical models that fail to account for individual agents, and ABMs commonly applied to simulate the spread of respiratory infections. This work uses agent-based modelling (ABM) to simulate sexually transmitted infection (STIs) spread within a population of 1000 agents over a 10-year period, as a preliminary investigation of the suitability of ABM methodology to simulate STI spread.
