  • 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.

  • The Practical Application of ISO 9001 and ISO/TS 16949 to the Mass Production of Motor Industry Components
    Computers & Industrial Engineering, 2012
    Co-Authors: Peter George Blaine, P. J. Vlok, Robert T. Dobson
    Abstract:

    Quality, as a scientific concept, is a characteristic which is generally little understood and difficult to define. The International Organisation for Standardisation (ISO) is an inter-governmental organisation based in Switzerland tasked with drawing up standards for a multitude of applications in business, government and society. The standards which specifically deal with quality are the ISO9000 series and, specifically for the motor industry, ISO/TS 16949.  These form the basis for ever more universally accepted standards for quality management systems.  ISO/TS 16949 is a derivative of ISO 9001 with additional requirements centred on the use of statistical tools with the purpose of developing manufacturing systems which will warrant that product and service comply perfectly with the customer’s specifications and requirements.  The objective is to eliminate the need to inspect outgoing or incoming product, saving time and expense while building confidence and trust between supplier and customer. This paper describes the effects on a powder metallurgy facility which manufactured mass produced components principally for the motor industry. The techniques and principles developed can be used in any manufacturing facility with consequent savings in time and money. An example is given of the use of Pre-Control Charts to ensure the production of acceptable parts.  The use of Pre-Control Charting empowered and increased the motivation of factory personnel who, in the particular facility described, were generally often technically illiterate. The importance of the application of Asset Care to all elements used in the  manufacturing process is stressed.

    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

  • Method of Computerized Maintenance Management System (CMMS) for Efficiency and accurate in Manufacture
    2012
    Co-Authors: Risko Liza
    Abstract:

    This information is built to help nurses manage their Care more effectively by the ability to see all the information about an Asset in one location including the Assets they use in it, either one is a stock room taken part and how much is available in the room supplies. This data is often also used to check compliance with regulatory laws. The device is a computerized maintenance management, Asset Care in a computerized data base, inventory, and information experts with an organization. Some large companies such as Oil and Gas, the company processing, HealthCare, a resort and hotel, physical Assets such as building, infrastructure, and equipment of a large proportion of the overall Asset with an organization. The industry agrees with high Assets and equipment in which one can be damaged very high expenditure and results are disturbing to the business. This is the reason that the organization must be properly organized and effective in the Care of their Assets. The Company must, of course want to use the device that remains resilient or at least survive until the time of use have been unsuitable. We do not discuss the large scale treatment as above. Another discussion is the operation of the computer devices such as PC Computer, Monitor, Printer, Scanner, etc. in an effort to keep the devices are available for operation by not issuing funds so great. Each device is damaged either back with the same case the company still needs to raise. And the company did not know anything about any damage to the device. Damage to the device could be a small part inside the damaged device still costs must be incurred is considered a great device. The company wanted a solution precisely to avoid such a large expenditure, external power efficiency, effective and accurate.

  • development application for computerized maintenance management system cmms in the central sterile supply department cssd and the surgery room
    Jurnal JSIKA, 2017
    Co-Authors: Rival Widyananda, Teguh Sutanto, Romeo Romeo
    Abstract:

    Department of Surgery is one of department at the Hospital that is important and are directly related to patient safety. The main business processes in the Department of Surgery consists of three processes, namely the sterilization process performed on unit Central Sterile Supply Department (CSSD), the process of Asset preservation operations and management processes. Current problems now is Asset preservation maintenance in the CSSD and the Operations Room at the RSPG as well as (1) an inventory of the equipment is not good, making it difficult for the Department of Surgery at tracking the existence of tools, (2) determine the condition of Asset status if available or not available when needed, (3) how the track record / history medical equipment, (4) any device that is often susceptible to interference, and (5) how the records or documentation of results maintenance is performed. The solution to these problems is a CMMS application, where the application can CMMS Asset inventory along with the location of Assets, Asset maintenance record of all processes in order to know the status of Assets and Asset maintenance history and generate documentation in the form of maintenance reports and provide information such as dashboard graphs Asset Care process.
