Using a condition monitoring (CM) system, the machine condition is assessed by the current and historical measurements of one or more of relevant CM parameters. CBM is defined as the preventive maintenance based on performance and/or parameter monitoring and the subsequent actions. Ĭondition-based maintenance (CBM) is a maintenance strategy that monitors the actual condition of the asset to decide what maintenance needs to be done. Another shortcoming of PM is the lack of decision support systems and insufficient historical data.

This means that if the distributions have a small standard deviation, they are usually a candidate for PM and in such cases PM is economical. One of the disadvantages of the PM is that PM is only suitable when the standard deviation of the failure population is small. Therefore, traditional preventive maintenance models are using policies such as age replacement and block replacement. Preventive maintenance (PM) is comprised of maintenance activities that are undertaken after a specified period of time or amount of equipment used. Waeyenbergh and Pintelon suggest that one should determine the economic feasibility in order to evaluate the technical feasibility of FBM for a critical component or a non-critical component. This depends on the existence of secondary damage, redundancy and the ease to repair. However, it is always possible that a failure is allowed to occur. In this regard, more emphasis is being placed on developing maintenance concepts. However, increasing global competition, small profit margins, safety awareness and strict environmental regulations are changing the environment that most companies are facing today. This approach is only appropriate in a case where customer demand exceeds supply and profit margins are large. Maintenance is carried out only after a breakdown. No action is taken to detect or to prevent failure. Failure-based maintenance (FBM) prescribes activation of maintenance in the event of failure. The development of maintenance approaches are discussed by many authors. strategies and concepts, methodology or philosophy) have been developed in the last few decades. In this chapter two case studies are presented: first, empirical case study will be utilised to evaluate and select the most appropriate maintenance approach the second one, based on expert opinion will present a possibility to formalise the importance levels for the importance of factors of sustainability of employee suggestion schemes.ĭifferent maintenance approaches (i.e.

To make the pairwise comparisons, we need a scale of numbers that indicate how many times a more important or dominant element over another element was, with respect to the criterion or property, with respect to which they are, compared. Moreover, this technique allows for the search of relative importance placed on product attributes and attribute levels of the analysed complex goods. AHP method is used to measure the importance of these factors. The method helps to decompose their decision problem into hierarchy of factors, each of which can be analysed independently and once the hierarchy is built, the decision makers systematically evaluate its various elements by comparing them one to another, two at a time, with respect to their impact on an element above them in the hierarchy. The AHP method has been widely used in the decision-making problems that involve multiple criteria in multiple levels as well. For example, in the study, the fuzzy AHP was employed to prioritise and select a suitable organisational structure. However, this method can also be utilised in many other fields. ĪHP gained substantial attention as a possible solution to the decision-making problems in different organisational areas, for example, the selection of maintenance policy or factors of employee suggestion schemes which will be more deeply illustrated in the following section. Experts are interviewed and pairwise comparison judgements are applied to pairs of homogenous criteria, eventually generating the overall priorities for ranking the alternatives. It is based on experts’ judgements through pairwise comparisons. The AHP helps the decision makers to organise the critical aspects of a problem into a hierarchical structure similar to a family tree. It represents a powerful technique for solving complicated and unstructured problems that may have interactions and correlations among different objectives and goals. The analytic hierarchy process (AHP) is widely used in multi-criteria decision-making tool for tackling multi-attribute decision-making problems in real situations.
