在现代社会，几乎所有的组织都使用建筑物、车辆、设备和机械等实物资产来开展业务活动。这些资产在其生命周期中消耗了大量的资金，因此，实物资产管理已成为影响任何组织的盈利能力的一个重要方面。随着时间的推移，所有资产都会恶化，资产的故障将增加维护的需要。适当的维护可以延长实物资产的使用寿命。然而，在使用寿命结束时，组织必须用合适的新产品取代它们。更换资产需要巨大的投资，因此，他们大多试图通过维修和维护来延长资产的使用寿命。然而，在某些情况下，即使资产处于良好状态，组织也会决定更换资产。根据之前的研究人员，行业中的许多资产都比它们最初设计的寿命更老，在许多情况下，无法更换它们导致了高能耗、高维护成本和增加了事故和灾难的风险。另一方面，各组织因不必要的实物资产更换而受到负面影响。因此，在这两个相互矛盾的选择之间做出决定，对资产所有者来说是一个巨大的挑战。实物资产修复/更换的决策涉及选择一个合乎逻辑的选择，并确定最适合特定情况的选项。了解如何确定最适合组织运营的选项以及何时更换资产将有助于控制停机时间和意外成本。虽然资产维护受到越来越多的关注，但在资产置换领域还缺乏全面的研究。因此，本文的目的是回顾实物资产修复/更换决策实践的文献。一项全面的文献审查确定了资产更换的原因和触发实物资产修理/更换决策过程的因素。在下一阶段的研究中，文献研究结果将用于评估斯里兰卡目前实物资产修理/更换决策的做法。关键词：实物资产置换；实物资产修复；决策
Abstract In modern world, almost all the organisations use physical assets such as buildings, vehicles, equipment and machinery, etc. to carry out their business operations. These assets consume a considerable amount of money during their life cycle and therefore, physical asset management has become an important aspect which affects the profitability of any organisation. All assets deteriorate over time and failures of assets will raise the need for maintenance. Proper maintenance can extend the life time of a physical asset. However, at the end of useful life time, organisations have to replace them with suitable new ones. Replacement of an asset requires enormous investments and therefore mostly, they try to extend life time of assets through repair and maintenance. However, in some situations organizations decide to replace assets even when they are in a good condition. As per previous researchers, many assets in the industry are older than the life they were originally designed for and in many cases, failure to replace them have led to high energy consumption, high maintenance costs and increased risk of accidents and calamities. On the other hand, organizations have experienced negative impacts due to unnecessary replacement of physical assets. Hence, making a decision between these two contradictory options presents a big challenge for asset owners. Decision making in physical asset repair/replacement involves selecting a logical choice and determining the option, which is the best for the particular situation. Knowing how to decide which option is best for organization’s operations and when assets should be replaced will help to control downtime and unexpected costs. Though asset maintenance has received an increasing attention, there is a lack of a comprehensive research in the area of asset replacement. Therefore, the aim of this paper is to review the literature on physical asset repair/replacement decision making practices. A comprehensive literature review identified the reasons for replacement of assets and the factors that trigger physical asset repair/replacement decision making process. The literature findings will be used to evaluate the current practice of physical asset repair/replacement decision making in Sri Lanka, in the next phase of study.
