“…Referring to the study done by Tendayi and Fourie [44], one of the findings indicate that obsolete parts and redundant parts also lead to high spare parts cost. This could be the consequences of having various types of inventories due to obsolete and redundant spare parts and lag of real time stock monitoring system as illustrated in Figure 3.…”

It is a known fact that the cost of maintaining rolling stock is huge due to its higher acquisition cost and maintenance activityneeded to sustain itsreliability, availability, maintainability,and safety. This research paper aims to analyse, evaluate, and rank the variables that influence therolling stock maintenance cost.A quantitative researchmethodwas adopted for data collection. Data collection involving five train operating companiesthat include Malaysia's rolling stock practitioners was accomplishedusing a survey. The research first identified the influential variables associated with rolling stock maintenance cost through systematic literaturereview. Then, 14 influential variablesand five groups of factors that affect rolling stock maintenance costwere identified. Variables identified were used as basis for designing the survey. Judgmental sampling was utilized for sampling purposes. The data collected from survey were analysedusing importance index to accomplish ranking analysis.The research has discovered that spare part cost, manpower cost and equipment cost are the highestrankedinfluential variables contributing towardsrollingstock maintenance cost. This study has highlighted the possibility of future major studies concerninginfluential costin establishingcost predictive model for rolling stock maintenance.

“…The knowledge related to the costs of the vehicle operation phase allows the supplier to reduce the risk of voiding the warranty and increase their sales capacity of tram rolling stock. It may also increase the sales potential and bidding advantage when negotiating sales terms, which may lead to additional financial benefits [4][5][6][7][8][9][10]. The methods of calculating lifetime cost varies mainly according to the number of divided phases; nevertheless, common elements can be found in these methods, like defined cost structure or economic efficiency, e.g.…”

The aim of this paper is to develop a quantile method of cost analysis allowing identification of the most cost-generating malfunctions occurring in a fleet of public transport vehicles. The exemplification of this method has been performed for a fleet of a specified type of trams. The idea behind the quantile method of public transport vehicle operating cost analysis is the reversing of the accumulated function of costs, for the determination of which a cost database from a given operating time of a public transport vehicle fleet has been used. The paper presents data on the malfunctions from the first five years of operation of trams in a large transport company. The assumed time of five years results from the warranty period provided by the manufacturer. The recorded number of indexes of replaced parts was 547. The group contained inoperative parts that were renewed several times.

“…This paper acknowledges the important role that maintenance plays in the life of a product or system, and incorporates it into the traditional economic life cycle costing approach with an emphasis on the cost of ownership and the effective maintenance and replacement strategies that influence it. As a follow-up to work done by Tendayi and Fourie [2], this paper addresses the issue of uncertainty in life cycle costing -an aspect that the earlier paper did not address.…”

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.
