A real-time evaluation method for modification priority of data module in civil aircraft technical publications

Abstract

Purpose The purpose of this paper is to present a priority evaluation method for data module (DM) modification tasks based on the thoughts of real-time systems. Tasks in practical cases can be sorted by this method after analyzing their time records. Civil aircraft technical publications (CATPs) are the key technical guarantee for aircraft companies to efficiently operate and service aircraft. Orienting the maintenance business of CATPs, this method regards DM as the research object to help DM editors efficiently finish their time-consuming work. Design/methodology/approach This method provides a priority order of modification tasks for DM editors by calculating two indicators: priority value (PV) and priority level (PL). Table of task priority must be first designed for certain evaluation work followed by generating PLs and PVs of modification tasks. Then editors can fully understand the urgency of these tasks using the rank orders of these two indicators. Findings This method can be applied into a software system used by CATPs department of aircraft manufacturers. According to the engineers’ opinions from a manufacturer in China, it is convenient for the practical application. Originality/value Availability and rationality are verified by the practical case and a software system. In addition, the originality characterized by a thinking for engineers to quantify the evaluation work of DM modification task priority, and they could also customize this method by taking modification difficulty and other factors into account.
