Abstract The article presents a method for assessment of availability and risk functioning of technical objects (transport means) in an executive subsystem. Indexes of the availability and risk connected with functioning of a single technical object have been determined on the basis of a mathematical model of the operation and maintenance process, in the studied transportation system. A Mathematical model of the operation and maintenance process has been developed with acceptance of an assumption that the process model is to be represented by a homogeneous Markov model X(t).

The full potential of predictive maintenance has not yet been utilised. Current solutions focus on individual steps of the predictive maintenance cycle and only work for very specific settings. The overarching challenge of predictive maintenance is to leverage these individual building blocks to obtain a framework that supports optimal maintenance and asset management. The PrimaVera project has identified four obstacles to tackle in order to utilise predictive maintenance at its full potential: lack of orchestration and automation of the predictive maintenance workflow, inaccurate or incomplete data and the role of human and organisational factors in data-driven decision support tools. Furthermore, an intuitive generic applicable predictive maintenance process model is presented in this paper to provide a structured way of deploying predictive maintenance solutions.

To study the maintenance resources deployment optimization, the resource usage characteristic was analyzed and a maintenance process model was constructed considering multi-team sharing test equipment. Applying model, the quantitative analysis was made and the maintenance performance of different resources deployment was provided.

Introduction of new technology (technology implementation) within an organisation can have wide reaching implications, beyond the effectiveness and efficiency savings that are typically the aim of such an endeavour. The ‘Health and Prognostic Assessment of Railway Assets for Predictive Maintenance’ project developed a prognostic tool, which aimed to support enhancement of the London underground’s remote condition monitoring system to support change from reactive and preventative to predictive maintenance, in order to increase effectiveness and efficiency and reduce lost customer hours. This paper investigates the organisational challenges associated with the introduction of such a tool. The paper describes the approach adopted to model the extant maintenance processes (focusing on role mapping) and associated organisational structures which revealed issues such as unclear processes, poor communication and data sharing links and problems with delineation of responsibility for decision making. It also describes the development of a new maintenance process model that incorporates the additional functionality of the new prognostic tool, taking in to account changes of roles, responsibilities, organisational processes and activities.

In this study, an analysis is made of facility maintenance process and its modeling for economic analysis. Especially, we are looking after the modeling method for estimating its cost through input data based on facility information. This allows biding for some plant operating and maintenance orders through results of cost estimation and economic analysis. Thus, we can make proper cost sheet of plant operation and maintenance through systematic cost assessment, reliable operation and maintenance related projects in the bid through management. Furthermore, we are going to conduct a case study to apply the above mentioned model.

Green highway is a roadway planned and designed with desires to integrate transportation functionality and ecological. A green highway takes high consideration on the approach of environment to the transportation system development, the ecosystem, urban growth, public health and also to surrounding communities. Reference to standard system such Green Roads Rating System becomes more popular being used to measure the classification of a green highway. This journal paper aimed to discuss on how important is the energy efficiency criteria to be measured in the green highway development. Energy is considered highly related to highway development due to it is the most infrastructures involves in massive construction activities from its construction up to the operation and maintenance process. Relevant energy criteria in green highway development had been figured out and a checklist of the comparison among the current relevant reference in the green highway is highlighted in this paper. These identified criteria for energy efficiency are importance to be considered in Malaysian Highway Index. The criteria include the consideration on Energy Plan for Green performance strategies, energy plan for maintenance, grey and green compound and car park, rest and service area (RSA), toll plaza and interchange.
