Delay time modelling and software development

Abstract

Delay time modelling (DTM) is the process to establish the mathematical model
based on the delay time concept and then to use it for improving plant maintenance
management. The delay time model can be divided into a single component model
(component-tracking model) or a complex system model (pooled-components model).
DTM has been proved to be a methodology readily embraced by engineers for
modelling maintenance decisions. The application and research of delay time modelling
has come to a stage where a semi-automated tool can be developed. In this thesis, the
research on the software development of delay time modelling will be presented.
Firstly, delay time models for both a single component (or component-tracking
model) and a complex system (or pooled-components model) are introduced. The key
part is delay time parameter estimation, which will be presented in details using
available subjective, objective or both
Secondly, the development of the software package is presented. It includes
project analysis, database design, and program design. In the project analysis phase, the
delay time models are transformed to program models. All analysis of program models
consists of three parts, such as input, processing and output. In the database design
phase, some tables are created to store processing information, which is then used in
subsequent mathematical modelling. Detailed programming work is given in the
program design phase.
The major achievement of this research and an open discussion of future work
conclude the thesis.
