  • Proposing a Holistic Physical Asset Management Strategy to Implement in Food and Beverage Industries in South Africa
    Food Science and Quality Management, 2015
    Co-Authors: M.a. Van Heerden, P. J. Vlok

    Abstract:

    Due to the increased demand for high-quality products, quality has been identified as the key to success in many food and beverage manufacturing organizations. In order to fulfil the customer’s/consumer’s demand for high-quality products, not only quality, but delivery time and cost need to be considered as the production process of the food industry requires continuous operation of production line equipment. Thus, a good Asset management system is important for a manufacturing organization to enhance its competitiveness. For this reason, ISO 55000 series of international standards are advised to provide a standardized framework for an Asset management system. Although many food and beverage industries strive to continuously improve operations, external factors are outing the industry under pressure to maximize production capacity, improve product quality, and better align Assets to market dynamics. Thus, responding to this pressure, a holistic Asset management strategy that focus on Asset Care is suggested to the food and beverage industry, hence this study investigates this statement. In attempt of implementing ISO 55000 alongside total quality management (TQM), this study propose that a holistic physical Asset management strategy will be achieved. This would enable the organizations to develop and sustain within this competitive environment by aiming to earn the status Best-in-Class. A business case for the holistic approach was developed, engaging the examination of the requirements, objectives, organization alignment, financial benefits and the impact that this approach will generate. This study therefore endeavour to improve overall organization excellence in developing countries as well as aims to inform relevant South African food and beverage organizations on the topic of the need and importance to implementing a holistic Asset management strategy as it represents a potential source of improvement. Keywords: Holistic strategy, physical Asset management, TQM, food, beverage.

  • Adapting Modern Portfolio Theory For Prioritising Asset Care Planning In Industry
    The South African Journal of Industrial Engineering, 2014
    Co-Authors: A. F. Van Den Honert, P. J. Vlok

    Abstract:

    Productivity improvement within any organisation can lead to increased turnover. This study focuses on developing a maintenance productivity improvement model that is based upon an established financial investment portfolio technique known as the Modern Portfolio Theory (MPT). The model can be used as a tool to minimise and diversify the long term risk associated with variances or fluctuations in the increase in productivity in multiple maintenance service centres. This is achieved by optimising the most efficient way of splitting resources, such as time and money, between these multiple service centres, resulting in increased productivity and a more constant maintenance work load. This model is verified through the use of an efficient frontier, resulting in a graphical method to determine the link between the expected increase in productivity and the standard deviation of the increase in productivity. Ultimately this model can be adapted for use in many sectors within an organisation, over and above the application in maintenance prioritisation. This study concludes that the model offers a simple tool to aid decisionmaking among various combinations of Assets within a maintenance context; and this model, adapted from MPT, was successfully validated with the use of an efficient frontier.

  • Statistical analysis of Caterpillar 793D haul truck engine data and through-life diagnostic information using the proportional hazards model
    The South African Journal of Industrial Engineering, 2013
    Co-Authors: W A Carstens, P. J. Vlok

    Abstract:

    Physical Asset management (PAM) is of increasing concern for companies in industry today. A key performance area of PAM is Asset Care plans (ACPs), which consist of maintenance strategies such as usage based maintenance (UBM) and condition based maintenance (CBM). Data obtained from the South African mining industry was modelled using a CBM prognostic model called the proportional hazards model (PHM). Results indicated that the developed model produced estimates that were reasonable representations of reality. These findings provide an exciting basis for the development of future Weibull PHMs that could result in huge maintenance cost savings and reduced failure occurrences.

  • Regression analysis of caterpillar 793D haul truck engine failure data and through-life diagnostic information using the proportional hazards model
    , 2012
    Co-Authors: W A Carstens

    Abstract:

    Regression Analysis of Caterpillar 793D Haul Truck Engine Failure Data and Through-Life Diagnostic Information Using the Proportional Hazards Model W.A. Carstens Department of Industrial Engineering, University of Stellenbosch, Private Bag X1, Matieland 7602, South Africa. Thesis: MScEng (Industrial) March 2012 Physical Asset Management (PAM) is becoming a greater concern for companies in industry today. The widely accepted British Standards Institutes’ specification for optimized management of physical Assets and infrastructure is PAS55. According to PAS55, PAM is the “systematic and co-ordinated activities and practices through which an organization optimally manages its physical Assets, and their associated performance, risks and expenditures over their life cycle for the purpose of achieving its organizational strategic plan”. One key performance area of PAM is Asset Care Plans (ACP). These plans are maintenance strategies which improve or ensure acceptable Asset reliability and performance during its useful life. Maintenance strategies such as Condition Based Maintenance (CBM) acts upon Condition Monitoring (CM) data, disregarding the previous failure histories of an Asset. Other maintenance strategies, such as Usage Based Maintenance (UBM), is based on previous failure histories, and does not consider CM data. Regression models make use of both CM data and previous failure histories to develop a model which represents the underlying failure behaviour of the Asset under study. These models can be of high value in ACP development due to the fact that Residual Useful Life (RUL) can be estimated and/or the long term life ii Stellenbosch University http://scholar.sun.ac.za
