Function Allocation methods are important for the appropriate allocation of tasks between humans and automated systems. It is proposed that Operational Event Sequence Diagrams (OESDs) provide a simple yet rigorous basis upon which allocation of work can be assessed. This is illustrated with respect to a design concept for a passenger aircraft flown by just a single pilot where the objective is to replace or supplement functions normally undertaken by the second pilot with advanced automation. A scenario-based analysis (take off) was used in which there would normally be considerable demands and interactions with the second pilot. The OESD analyses indicate those tasks that would be suitable for allocation to automated assistance on the flight deck and those tasks that are now redundant in this new configuration (something that other formal Function Allocation approaches cannot identify). Furthermore, OESDs are demonstrated to be an easy to apply and flexible approach to the allocation of function in prospective systems.
OESDs provide a simple yet rigorous basis upon which allocation of work can be assessed. The technique can deal with the flexible, dynamic allocation of work and the deletion of functions no longer required. This is illustrated using a novel design concept for a single-crew commercial aircraft.
功能分配方法对于在人类和自动化系统之间合理分配任务很重要。有人提出，操作事件序列图（OESD）为评估工作分配提供了一个简单而严谨的基础。这一点通过一个仅由一名飞行员驾驶的客机设计概念得到了说明，其目标是用先进的自动化技术取代或补充通常由第二名飞行员承担的功能。采用了基于场景的分析（起飞），在这种情况下，通常会对第二名飞行员有相当多的要求和交互。OESD分析指出了那些适合分配给驾驶舱自动化辅助的任务，以及在这种新配置中现在多余的任务（这是其他正式功能分配方法无法识别的）。此外，OESD被证明是一种易于应用且灵活的方法，可用于前瞻性系统中的功能分配。
OESD为评估工作分配提供了一个简单而严谨的基础。该技术可以处理工作的灵活、动态分配以及不再需要的功能的删除。这通过一种新型单机组商用飞机的设计概念进行了说明。
