Abstract
This article introduces maintenance informatics dashboard design approach for visualising maintenance, repair and overhaul events on a timeline. This paper presents a proposed methodology for aggregate visualisation techniques and a 2D graphical plot method as well as a summary of events on a timeline. In this paper, these events are occurrences which are classified and categorised into levels. The occurrences are accumulated over time as historical information and represented in a visual format over a timeline based on an entity relationship diagram. The information modelling technique with respect to data visualisation is emphasised. The result is a single-page-view of maintenance activities. The maintenance activities of aircraft engines are visualised to ease the accessibility of getting accurate and relevant information for making better maintenance decision. The result can be used to gain insight of the root cause of the events from inception to end of life of the engine.
Highlights
Visualisation is changing the way information is presented in through-life engineering perspective [1]
The remaining sections of the paper are as follows: Section 3 describes the methodology for graphing the timeline, section 4 defines the information modelling technique, section 5 describes the implementation of the events timeline application, section 6 is the case study, section 7 presents the results and discussion, and section 8 is the conclusion with future work
An information modelling technique is used to model the timeline visualisation of engine events, while information architecture supports the visualisation of personal history in the medical application [3]
Summary
Visualisation is changing the way information is presented in through-life engineering perspective [1]. Information modelling of engine event histories is discussed to demonstrate the data organisation displayed in a concise and accurate way. The remaining sections of the paper are as follows: Section 3 describes the methodology for graphing the timeline, section 4 defines the information modelling technique, section 5 describes the implementation of the events timeline application, section 6 is the case study, section 7 presents the results and discussion, and section 8 is the conclusion with future work. LifeLines were implemented to present a personal history overview on a single screen, offer direct access to all comprehensive information from the overview with a single or double mouse click It makes critical information or alerts visible at the overview level.
