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).

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.

The paper proposed an application of intelligent AC-DC integrated power supply system in 500kV switching station. Firstly, this paper introduced current situation of AC-DC power supply system which is for home use and provided main components of this intelligent power supply system and its functions. And then, all cautions in operation and maintenance process is explained. Lastly, this paper summarized problems exposed in the system after running half year in 500kV switching station and put forward some aspects needed to be improved.
