摘要: 过去利用统计方法所作的研究中,并无证据显示航空公司的财务状况、是否为新进的航空公司、解除管制政策本身或管制政策衍生的改变等因素会显着影响飞航安全。而相关飞安理论也显示出,飞安绩效的好坏实掌握在公司本身对飞安管理的理念与用心。因此,本研究藉由解构航空公司之飞安管理流程,了解各运作程序对飞安绩效的影响关系,并以错误树分析方法之概念提出一可行之绩效衡量模式。至于模式之构建则分为:界定研究范围、构建飞安管理机制、界定流程潜在失误、架构错误树、订定节点评估指标、衡量节点绩效以及错误树分析等七个步骤。
本研究以航务运作为主要研究范围,并将航空公司飞安管理机制分为实体运作流程与安全资讯分析系统两大项。其中,实体运作包括聘用飞行员、非外宿待机、签派以及外宿待机四个流程,而安全资讯则涵盖考核、属性、训练、外宿抽查作业、组员指派作业、飞航计画、货物装载、油料装载、线上维修以及外部清洁作业等十个分析系统。经进一步整合上述飞安管理之内涵,共构建出相关之错误树六组,分别为聘用不适任飞行员、飞行员未具有安全执行任务之充分条件、装载及平衡错误、设备故障错误、外部清洁作业错误、不适任飞行员执行任务等。
经由简例分析发现,错误树分析方法确可有效评估各流程运作绩效;利用简单试算表分析,即可求得各项指标投入对流程运作绩效的影响程度,其可供航空公司或主管机构作为评鉴飞安绩效之有力工具。
There is no distinct evidence showing in the previous statistic studies that factors such as the financial status of airlines, the length of entering the industry, the deregulation policies itself and the changes deriving from the various regulation policies have significant impact on air safety. Moreover, some theories also infer the performance of air safety lies in the manager’s endeavor on this issue. Therefore, this thesis aims at the interrelations between the operational procedures and the associated impact of air safety via analyzing the management process. In the end, a model based on fault tree analysis was constructed for assessment which consists of the following steps: set scope of the study, establish the mechanism of airline safety management, identify the latent faults in the process, construct the fault tree, set up node indices for assessment, assess the results of nodes, and analyze the fault tree.
This thesis is mainly concerned on the flight operations, of which the mechanism of airline safety management is divided into physical operation process and safety information analysis system. The physical operations include: pilots recruit, practice on home base, flight dispatch, and practice during outside stay. The safety information analysis system include: pilot performance, pilot attribute, pilot training, stay-over check, crew assignment, flight plan, cargo loading, fuel loading, on-line maintenance, and configuration clearance. After examining the safety management content carefully, six types of fault tree are therefore established. They are: recruit incompetent pilots, pilots without adequate capability to perform missions, errors in loading and balancing, errors in facility breakdown, errors in configuration clearance, and flight performed by incompetent pilots.
Illustrated by a simple numerical example, the results have shown that this fault tree approach is effective to assess the performance of flight operations. Furthermore, by employing the trial balance analysis, the impact of various inputs on airline safety performance can be easily evaluated. Thus, the fault tree analysis can be a powerful tool both for airlines and the authorities to measure effectiveness of an air safety program.
