Abstract

The Federal Aviation Administration's (FAA) Next Generation Air Transportation System (NextGen) and EUROCONTROL's Single European Sky ATM Research Program (SESAR) are transforming the global Air Traffic Management (ATM) as we know it today and will break up with existing roles predicated by 50 year old technology [1, 2]. Similar to SESAR, NextGen right now runs the risk to specify ATM systems based on architectures already out-of-date. While current functionality is based on historical grown technical restrictions, a performance-based and most efficient approach requires new paradigms and eventually has to lead to a balanced approach to prevent over-optimizing one area at the expense of others [3]. The new approach should be based on semantically enriched service models allowing easier development and modular applications for multiple domains. This paper describes an ontology based multi-domain software development approach called Ontology-Based-Control-Room-Framework (ONTOCOR) featuring high software code re-usage and rapid development. It focuses on improving efficiency and increasing the code reusability in order to achieve SESAR's and NextGen's claim for a performance-based and cost-efficient system [2]. The main goal is using semantic technologies to enhance software development in ATM and further, to define tasks with enough similarity to allow applicability in different domains. ONTOCOR uses semantic standards and tools, and seamless information interchange. As described in the European Air Traffic Management Master Plan, “The Information Management Work Package (…) defines the ATM Information Reference Model and the Information Service model (…) by establishing a framework, which defines seamless information interchange between all providers and users of shared ATM information” [2]. A specific example to implement inter domain, is the European ATM Information Reference Model (AIRM). In general, domain independent implementation of components is a future goal and EUROCONTROL defines AIRM as a model, which contains all of the ATM information to be shared in a semantic way [4]. The paper will discuss a first case study for ontology-based modeling and development, a service for digital notices to airmen (NOTAM). Fast information distribution and retrieval are key elements together with service modeling and definitions according to Enterprise Architecture (EA) and SOA principles. Aeronautical Information Management (AIM) using ontologies, provides the benefit of fast ramp up of on-the-spot services, reduced development efforts and additional defined data as source for collaborative decision making within the System-Wide Information Management (SWIM) [5]. Such services deployed in NextGen and SESAR will optimize operations workflow, communication needs, and information sharing.
NextGen和SESAR正朝着基于本体的软件开发方向发展
美国联邦航空管理局(FAA)的下一代航空运输系统(NextGen)和EUROCONTROL的单一欧洲天空空中交通管理研究计划(SESAR)正在改变我们今天所知道的全球空中交通管理(ATM),并将打破50年前技术所预测的现有角色[1,2]。与SESAR类似,NextGen目前也面临着基于已经过时的架构指定ATM系统的风险。虽然当前的功能是基于历史发展的技术限制,但基于性能和最有效的方法需要新的范例,最终必须导致一种平衡的方法,以防止以牺牲其他方面为代价过度优化一个领域。新方法应该基于语义丰富的服务模型,允许更容易地为多个领域开发和模块化应用程序。本文提出了一种基于本体的多领域软件开发方法——基于本体的控制室框架(ONTOCOR),具有软件代码复用率高、开发速度快的特点。它专注于提高效率和增加代码可重用性,以实现SESAR和NextGen对基于性能和成本效益的系统[2]的要求。主要目标是使用语义技术来增强ATM中的软件开发,并进一步定义具有足够相似性的任务,以允许在不同领域的适用性。ONTOCOR使用语义标准和工具,以及无缝的信息交换。正如欧洲空中交通管理总体规划所描述的那样,“信息管理工作包(…)通过建立一个框架来定义ATM信息参考模型和信息服务模型(…),该框架定义了共享ATM信息的所有提供者和用户之间的无缝信息交换”[2]。实现跨域的一个具体例子是欧洲ATM信息参考模型(AIRM)。通常,组件的领域独立实现是未来的目标,EUROCONTROL将AIRM定义为一个模型,其中包含以语义方式共享的所有ATM信息[4]。本文将讨论基于本体的建模和开发的第一个案例研究,即面向飞行员的数字通知(NOTAM)服务。快速的信息分发和检索,以及根据企业架构(EA)和SOA原则进行的服务建模和定义,都是关键要素。使用本体的航空信息管理(AIM)提供了快速增加现场服务的好处,减少了开发工作量,并为全系统信息管理(SWIM)[5]中的协作决策提供了额外的定义数据来源。在NextGen和SESAR中部署的此类服务将优化操作流程、通信需求和信息共享。
