Application Domain Examples
See below for example MP models in different application domains.
This solution-neutral operational process model of a Search and Rescue (SAR) mission shows the required interactions among five participants.
Business Process / Workflow Modeling
This model of the spiral software process illustrates the use of MP to model high level processes employed by individual roles within an organization.
A model of an overdose situation to inform policy on rescue medication administration turns up an unintended scenario in which the victim receives the rescue medication twice from lack of coordination.
A UAV is decomposed into subfunctions that interact with the operator and the environment. Automated annotations describe important aspects of this scenario.
A commercial flight is modeled, showing interactions among passenger, pilot and controller (top row) across seven phases (left column).
A scenario from a model of a spacecraft communications system as it approaches to dock with the International Space Station (ISS). The absence of this particular scenario from the model was noticed and subsequently corrected by the student author.
A scenario from an MP model of an unconstrained stack (allowed to try to pop an empty stack) illustrates how to pinpoint events that violate a certain property, and how to annotate these particular events in the trace with additional messages.
Networks & Communications
An example scenario from a model of network ring, where each node interacts with its left and right neighbors only.
General Systems and Emergence Research
An MP model of the Cycles isomorphic systems process (ISP) containing two of at least five cycles patterns shown to arise from a small model of 6 lines of code.
A scenario from a model of an autonomous automobile's interactions with its user.
A scenario from a model of a manufacturing process.
A scenario from a model of a logistics process (two producers, transportation, supply office, and two consumers).
A scenario from a model of a decision making process in the context of a medical procedure (a physician in the leader role, and nurses in the subordinate role).
Power & Energy
An example scenario from a model of a spent nuclear fuel cooling pool shows the interactions between the cooling pool and external systems including operator, heat exchanger, and water makeup system.
Sports & Entertainment
An example model from a car race model with two cars and a judge.
Lifecycle Phase Application Examples
Concept of Operations
Use MP during concept development to create a model of the problem. Show the MP event traces to stakeholders for feedback on whether or not the model accurately and fully captures the problem to be solved. Fix misinterpretations about the problem.
Requirements & Architecture
Use MP to describe the architecture-level behavior that solves the problem of interest. Formulate and test the logic, completeness and consistency of requirements for the system under design. Fix misinterpretations and errors pertaining to the architecture of behavior of the high level elements.
Use MP to describe the detailed behaviors as allocated to software, hardware, people, facilities, or some combination thereof. Fix errors in component behaviors.
Integration, Test, and Verification
Use MP to systematically create an exhaustive set of test cases up to the user-defined scope limit, from which a subset may be selected and prioritized for live testing. Use live test results to validate synthetic test results that were obtained through simulation only. Use simulation results to verify that scenarios that could not be live-tested also meet requirements.
System Verification & Validation
MP helps us make more complete predictions about possible alternative system behaviors, learn about critical issues are concerning interactions among parts of the system and between the system and its environment, and exclude undesired behaviors from the design before their manifestation in the actual system. With MP, verification & validation of the system model is concurrent with model development throughout every phase of the lifecycle. During this phase the actual system behavior is checked against the MP-modeled system behavior.
Operations & Maintenance
An MP model of a fielded system may be used as a "digital twin" to verify and validate proposed changes to the configuration before actually making those changes in the real system.
