Scenarios（场景）¶
Scenarios allow you to interact with your modeled universe, unlocking the ability to ask “What if” questions to simulate different operating conditions. To learn more about Palantir's high-level approach to connecting models with organizational outcomes, refer to Models in the Ontology.
Configured against your system graph, a scenario evaluates actions along with one or more modeled inputs and computes the output value to reflect the real-world interactions of your digital twin. The integrated power of Vertex allows you to model multiple sets of interactions and automatically chain these together to forward the outputs of one model as the inputs to another. This allows you to understand and interact with multiple processes across multiple systems to understand the end-to-end impact of a proposed change.
Business logic and models in Foundry¶
In order to simulate operating conditions, you first need to define these conditions, their ontological relationships, and expected behavior. You can do this through the creation of Functions on models where you can author, evaluate, and deploy business logic based on models within Foundry.
Consider models as jobs that take a pre-defined set of inputs and return a set of calculated outputs. The model version specifies the input and output parameters and can be configured alongside the ontological objects seen in your system graph. This allows you to closely align your modeled concepts with your digital twin to provide dynamic system interactions. Learn more about Machine Learning and Modeling in Foundry..
Once published as actions, Functions on models will be available for configuration in Vertex, where you can interactively run scenarios to understand the impact of potential operating conditions.
Functions in Foundry enables code authors to write logic that can be executed quickly in operational contexts, such as dashboards and applications designed to empower decision-making processes. Once published, Functions can also be used in Vertex to support dynamic simulated case studies. Learn more about Functions.
Time series for scenarios¶
To understand and interact with changes to your system over time, it is critical to shape your measured values as time series in order to configure these as inputs to your model which will generate calculated time series outputs for comparison. This will allow you to monitor your current state, view historic trends, and predict future changes with simulated overrides to modeled conditions.
You can find more information on time series setup in the time series documentation. Contact your Palantir representative for further assistance with time series.

场景¶
场景（Scenarios）允许您与建模后的宇宙进行交互，从而提出"假设"问题来模拟不同的运行条件。要了解 Palantir 将模型与组织成果相连接的高层次方法，请参阅本体中的模型。
场景基于您的系统图进行配置，评估操作以及一个或多个建模输入，并计算输出值，以反映数字孪生的真实世界交互。Vertex 的集成能力使您能够对多组交互进行建模，并自动将这些交互串联起来，将一个模型的输出作为另一个模型的输入。这使您能够理解和交互跨多个系统的多个流程，从而了解拟议变更的端到端影响。
Foundry 中的业务逻辑和模型¶
为了模拟运行条件，您首先需要定义这些条件、它们的本体关系以及预期行为。您可以通过创建模型上的函数来实现这一点，您可以在其中编写、评估和部署基于 Foundry 中模型的业务逻辑。
将模型视为接受预定义输入集并返回计算输出集的任务。模型版本指定输入和输出参数，并可与系统图中看到的本体对象一起配置。这使您能够将建模概念与数字孪生紧密对齐，从而提供动态的系统交互。了解更多关于 Foundry 中的机器学习和建模的信息。
一旦作为操作发布，模型上的函数将可在 Vertex 中进行配置，您可以在其中交互式运行场景，以了解潜在运行条件的影响。
Foundry 中的函数（Functions）使代码编写者能够编写可在操作环境中快速执行的逻辑，例如旨在赋能决策过程的仪表盘和应用程序。发布后，函数也可在 Vertex 中使用，以支持动态模拟案例研究。了解更多关于函数的信息。
场景的时间序列¶
为了理解并交互系统随时间的变化，将测量值塑形为时间序列至关重要，以便将这些值配置为模型的输入，模型将生成计算后的时间序列输出用于比较。这将使您能够监控当前状态、查看历史趋势，并通过模拟覆盖建模条件来预测未来变化。
您可以在时间序列文档中找到有关时间序列设置的更多信息。如需进一步的时间序列帮助，请联系您的 Palantir 代表。
