Purpose – Asset management has recently gained significance due to emerging business models such as Product Service Systems where the sale of asset use, rather than the sale of the asset itself, is applied. This leaves the responsibility of the maintenance tasks to fall on the shoulders of the manufacturer/supplier to provide high asset availability. The use of asset monitoring assists in providing high availability but the level of monitoring and maintenance needs to be assessed for cost effectiveness. There is a lack of available tools and understanding of their value in assessing monitoring levels. The paper aims to discuss these issues. Design/methodology/approach – This research aims to develop a dynamic modelling approach using Discrete Event Simulation (DES) to assess such maintenance systems in order to provide a better understanding of the behaviour of complex maintenance operations. Interviews were conducted and literature was analysed to gather modelling requirements. Generic models were created, followed by simulation models, to examine how maintenance operation systems behave regarding different levels of asset monitoring. Findings – This research indicates that DES discerns varying levels of complexity of maintenance operations but that more sophisticated asset monitoring levels will not necessarily result in a higher asset performance. The paper shows that it is possible to assess the impact of monitoring levels as well as make other changes to system operation that may be more or less effective. Practical implications – The proposed tool supports the maintenance operations decision makers to select the appropriate asset monitoring level that suits their operational needs. Originality/value – A novel DES approach was developed to assess asset monitoring levels for maintenance operations. In applying this quantitative approach, it was demonstrated that higher asset monitoring levels do not necessarily result in higher asset availability. The work provides a means of evaluating the constraints in the system that an asset is part of rather than focusing on the asset in isolation.

In this paper, the authors' research work is focused on imperfect inspection policy investigation, when not all defects are identified during inspection action performance. They are interested in Block Inspection Policy performance for multi-unit systems, the maintenance policy which is one of the most commonly used in practice. As a result, at the beginning, few words about delay time modelling approach and a brief literature overview is given. Later, the model of Block-Inspection Policy is provided. The numerical example with the use of QNU Octave program is given. In the next Section, the sensitivity analysis of the developed model is characterised. The article ends up with summary and directions for further research. Streszczenie: W artykule autorzy skupili się na analizie nieperfekcyjnej operacji diagnozy stanu systemu, podczas której nie wszystkie symptomy o potencjalnym uszkodzeniu elementów systemu zostają wykryte. Swoimi badaniami autorzy objęli analizę jednej z częściej wykorzystywanych w praktyce polityk obsługiwania Block Inspection Policy (BIP) dla systemów wieloelementowych. W artykule przedstawiono krótki przegląd literatury z badanego obszaru, następnie omówiono koncepcję modelu BIP oraz przedstawiono jego model symulacyjny z wykorzystaniem oprogramowania QNU Octave. W kolejnym punkcie przedstawiono analizę wrażliwości badanego modelu. Pracę kończy podsumowanie i wskazanie kierunków dalszych prac badawczych. Słowa kluczowe: modelowanie relacji czasowych, utrzymanie w stanie zdatności, systemy wieloelementowe

“…These are necessary questions which need to be addressed in order to define relationships and estimate important parameters which can be used as an input to the maintenance management models (simulation models), (Al-Zubaidi and Christer, 1996). These and similar questions are investigated on the basis of such data as have been collected along with judgemental input.…”

Building maintenance has until recently been a neglected field of quantitative modelling and of academic study. It has not attracted very much attention despite being regarded as under‐funded, unproductive and poorly managed, or the recognition that many of its managerial problems are demanding more research and skills than those of new works. Discusses the priorities, categories of maintenance work, and factors affecting demand for maintenance. Based on general statistics obtained, identifies and quantifies both major problems areas (in terms of cost and frequency of maintenance activities) and the nature and cause of the demand for maintenance in a major hospital complex. They have revealed no coherent picture, in that demand from wards and building seems independent of patient throughput and age of buildings. The demand for maintenance, for the main trades involved, namely plumbing, joinery, electrical and mechanical have been forecast and arrival rate of jobs per trade has been estimated. This would enhance the management process and work planning which would result in a more economic use of resources and a corresponding reduction in the total cost of maintaining property to a standard.
