Asset/Facility Operations Modeling
Infrastructure operators interact with infrastructure systems by making decisions based on constraints and opportunities. To model such interactions, we need a general method to represent infrastructure decision processes. The ability to model these interactions allows prediction of not only the likely infrastructure operator response to external events but also the possible infrastructure impacts caused by those decisions.
This modeling develops and applies the capability to accurately model the
operation, function, and interrelationship of particular assets within an infrastructure
system. Humans interact with physical systems through implementing policy, assessing
situations, and making decisions based on constraints and opportunities.
The model uses
an agent framework to simulate the activities of facility and asset operators. The
framework enables modeling of routine activities as well as actions that are
more complex and require reasoning across capabilities, resources, and constraints.
The framework is developed in layers; each layer is demonstrated on a test
problem before it is made generally available for NISAC applications. The first
layer is the ability to perform routine activities by an operator, enabling
reactive behavior. The second layer is the ability to perform complex tasks
by reasoning over problem elements, which provides a planning capability. The
third layer, develops the ability to reason over problem elements while accounting
for the potential actions of other agents, enabling the development of strategic
actions that can be either cooperative or adversarial, depending on the environment.
There are many potential applications of
this capability to infrastructure modeling, including estimating demand
for urban infrastructure services (electrical power, telecommunications, water,
and natural gas) and modeling operations of electrical power generating plants,
hospital operations, elements of emergency services, ports, and the effects
of markets on infrastructure services.
Application of this capability to modeling specific assets
and facilities must be done in coordination with sector specialists, private facility owners, and domain specialists to describe the range of behavior to be modeled.
