Modeling and simulation

Modeling and Simulation (M&S) consists of creating the software representation of a real life object or phenomenon in order to execute it in different scenarios and study various aspects of its behaviour. Using representative models, often based on statistical data, simulation can be used to forecast the impact of a given “decision,” without the actual cost normally associated to this decision. Using M&S, managers and technical advisors can simulate the effect or evaluate the performance of an existing or proposed system and base their decisions on quantitative data and associated risks according to the metrics of their choice.

Weapon Systems

LTI has participated in several modeling and simulation projects on weapons systems directed by the precision weapons section of DRDC Valcartier. Through these projects, LTI, among others, conducted parametric, performance, tradeoff and lethality/vulnerability studies. These studies involved the modeling and simulation of various weapon systems: guided bombs, artillery munitions, missiles, real or conceptual.

Electro-Optics

LTI has developed and supported various simulation framework and models in the domain of electro-optics since its beginning. More precisely, implemented and validated different models of aerial platforms, decoy flares, weapons and sensors to study aircraft electro-optical (EO) defensive systems through different engagement simulation scenarios. LTI has also developed an infrared images analysis software and an infrared 3D scene generation software.

Behavior Models

LTI possesses the expertise to perform knowledge engineering that leads to the creation of behaviour models and the analysis and parametrization of such models inside a simulation environment. LTI developed the low-fidelity behaviour models to simulate multiple entities inside a large environment in order to recreate a realistic complex environment. Furthermore, LTI developed detailed human situational awareness and decision making models, which were integrated as part of a behavior model for a military simulation environment.

Physical Models

In addition its specialization in electro-optical and weapon system models, LTI is experienced with the creation of a variety of physical entities simulation models. LTI has implemented the models of various entities (platforms, sensors, weapons, countermeasures) to create representative scenarios for decision support application testbeds. LTI has also created different high-fidelity crane models for navy-based simulations.

Serious Gaming and Virtual Reality

LTI is capable of creating or modifying gaming engines in order to perform simulations that involve humans in the loop. This expertise includes the creation of configurable scenarios, customizing the gaming applications for specific requirements, the analysis of simulation results and even the creation of custom virtual reality environments. LTI has already modified and used some popular gaming engines and analysed humans (experimentees) performance in different scenarios, according to its client’s requirements.

Complex Situations

LTI has greatly collaborated to the development of a multi-agent-based simulation environment that aims to study how human deal with complex situations. The simulation scenarios that were created and the data collected from humans allowed our client to better understand and quantify the degree of comprehension of humans involved in the simulation.
