A Decision-Making Framework for Effective Maintenance Management Using Life Cycle Costing (Lcc) in a Rolling Stock Environment

Abstract

In this paper, a life cycle costing (LCC) framework for effective maintenance management is investigated and developed for use in a railway rolling stock environment. The framework consists of combining typical mission-critical components together with their failure and maintenance history. All costs related to the operation and maintenance of these components throughout their life cycle are also determined. The next step involves considering different scenarios under which the components can be used in relation to operations, maintenance, and replacements. The decision about which scenario to take is based on the one with the most favourable net present value after life cycle costing is performed over a specified period of time. A typical railway rolling-stock maintenance organisation in South Africa was used to highlight the practical implications of such a framework and how the company could make informed and appropriate decisions. The conclusion of this study is that such a framework is useful, and that it can be used as a basis for estimating LCC across a spectrum of critical assets found in the rolling stock environment. OPSOMMINGIn hierdie artikel is 'n lewenssikluskoste raamwerk ondersoek en ontwikkel om instandhoudingsbestuur in 'n spoorweg rollende materiaal omgewing te verbeter. Die raamwerk bestaan uit 'n kombinasie van tipiese missie-kritiese komponente saam met hulle falings-en instandhoudingsgeskiedenis. Alle koste verbonde aan die bedryf en instandhouding van hierdie komponente gedurende hulle lewenssiklus is ook bepaal. Deur verskillende bedryfscenario's se lewenssikluskoste te vergelyk in terme van netto huidige waardes, kan 'n besluit oor die beste scenario geneem word. 'n SuidAfrikaanse gevallestudie is gebruik om die waarde van hierdie raamwerk te illustreer. Resultate toon dat die raamwerk wel bruikbaar is oor 'n wye spektrum van scenario's.

Review of life cycle models for enhancing machine tools sustainability: lessons, trends and future directions

“…Life cycle framework in railway environment where rolling stock has a limited life span was found to be an important aspect in supporting the Reconfigurable Assembly Manufacturing System (RAMS). According to Fourie and Tendayi (2016) , it is essential to have a life cycle framework in the railway industry as Reconfigurable Assembly Manufacturing Systems (RAMS) has become the most significant part of decision taking in the railway manufacturing environment. The authors’ further stresses that the effective maintenance management is the key foundation in ensuring that the life cycle management is achieved and this can improve the overall profitability of the industry.…”

“…Similarly, with the DFA approach the number of parts can be significantly reduced in order to have a robust and lean assembly process. In other words, the design approach integrates all the necessary the tools and method of assembly for the production of a quality product ( Fourie and Tendayi, 2016 ).…”

“…Reconfiguration is an effective way of redesigning the components of a system to ensure efficiency, modularity, scalability and flexibility (Koren et al, 1999). Fourie and Tendayi (2016) delve into the possibility of developing and implementing a reconfigurable life cycle framework in the railway industry. Sibanda et al (2019) looked at the engineering design of the reconfigurable machine tool holistically.…”

Manoeuvring physical assets into the future

“…Si et al, 2011), Life Cycle Costing (LCC) (e.g. Ferry and Flanagan, 1991;Woodward, 1997;Asiedu and Gu, 1998;Fourie and Tendayi, 2016) and others are used for this purpose. However, these methods have a number of limitations.…”
