Increasingly, aerospace systems such as airplane engines have a substantial computer software component. Building such software is challenging, because the software must interact with mechanical devices , like sensors on an airplane wing, and with computer hardware. Moreover, this software must be reliable, robust, and above all, safe, i.e., it must be certified as acceptably safe for use. In building such software, engineers typically rely on ad-hoc design methods for control systems. These methods usually start with an abstract description of a proposed solution, expressed in several different styles: operational (describing steps to be taken) and declarative (describing properties that the software should possess). These descriptions are then step-by-step refined into executable programs.The aim of this project is to put this ad-hoc design method on to a formal footing, via the introduction of a new concept called a refinement pattern. A refinement pattern effectively captures the step-by-step refinements that engineers carry out in practice. We will provide formal, mathematical foundations for refinement patterns and for reasoning about refinements. We also intend to support this method by developing novel and specialised tools, including a specialised model checker, that integrate with the widely used Matlab/Stateflow design tool. This will help engineers produce more reliable, more robust aerospace systems by building on their established practices.

越来越多的航空航天系统，如飞机发动机，具有大量的计算机软件组件。构建这样的软件是具有挑战性的，因为软件必须与机械设备（如机翼上的传感器）和计算机硬件交互。此外，该软件必须是可靠的，健壮的，最重要的是，安全的，即，它必须被证明是可接受的安全使用。在构建此类软件时，工程师通常依赖于控制系统的ad-hoc设计方法。这些方法通常从一个建议的解决方案的抽象描述开始，以几种不同的风格表达：操作性（描述要采取的步骤）和声明性（描述软件应该拥有的属性）。然后，这些描述被逐步细化为可执行程序。本项目的目的是通过引入一个称为细化模式的新概念，将这种特殊的设计方法置于正式的基础上。细化模式有效地捕获了工程师在实践中执行的逐步细化。我们将为精化模式和精化推理提供正式的数学基础。我们还打算通过开发新的和专门的工具来支持这种方法，包括一个专门的模型检查器，该工具与广泛使用的Matlab/Stateflow设计工具相结合。这将有助于工程师通过建立他们的既定实践来生产更可靠，更强大的航空航天系统。
