The aim of this research work is to propose a fuzzy methodology-based integrated framework for the failure analysis of the transmission system of the TATA Company-made heavy commercial vehicle. Under the failure analysis failure mode effect analysis (FMEA) approaches has been applied and the critical components of the considered system were identified on the basis of their risk priority number (RPN). The identification of critical components on the basis of RPN score results in confusion to system analyst as it becomes difficult to allocate appropriate risk priorities under same RPN scores. Also, importance among the probability of occurrence of failure (O

Background Maintenance cost of machinery, equipment and tooling are main contributor to total cost of production in processing industry. The aim of study is to explore selection of optimum maintenance strategy for steam generating unit (SGU) in a coal fired thermal power plant using various MADM and graphical approach. The novelty of research work is selection of strategy based on agile enabler attributes and use of graphical approaches for decision making. This selection procedure allows for speedy conflux of large number of attributes, which gives the decision maker an effective tool select optimum strategy. Case description The practicality of the framework has been justified through implementation in thermal power plant, situated in northern part of India. The plant has total installed capacity of 2400 MW. It has eight units. The present study is done in unit number 8. Discussion and evaluation This selection is based on agile enabler attributes. Triangular fuzzy number (TFN) is used to take care of imprecise and vague judgements. For ranking of maintenance strategies MADM approaches of fuzzy AHP (FAHP), fuzzy TOPSIS (FTOPSIS); and Graphical approaches of Line graph and spider graph are used, respectively. Conclusion PDM has been ranked first by all evaluating approaches. There is also synergy in results. The proposed work not only provides the best alternative but also alternative ranking. The results will be shared with management for implementation so as to increase system availability and reduce operation cost.

Machinery, equipment and tooling maintenance cost are amongst the main contributors to cost of production in any manufacturing firm. Reducing cost of maintenance practices by eliminating waste or unwanted intermediate processes and selecting optimum maintenance strategy can result in win-win situation to get competitive edge in present day dynamic market where end user requirement is highly specific and rapidly changing. The aim of this paper is to integrate agile thinking with evaluation of different maintenance strategies for different equipment at a selected thermal power station. The paper also explores selection of optimum maintenance strategies at a power plant using extent analysis of fuzzy AHP.

The various sources of energy from which mechanical energy is obtained are non-renewable and are thus considered to be unsustainable. These sources include the various fossil fuels like the petroleum, coal and the natural gas. The burning of fossil fuels led to the production of the greenhouse gases increasing the levels of CO₂ in the atmosphere. The adverse effects are the global warming and the ozone layer depletion. In a nation like India, where consumable oils are still transported in, it is advantageous to investigate the likelihood of utilising such non-palatable oils as a part of CI motors which are not by and by used as cooking oil. Palm oil (otherwise called dendê oil, from Portuguese) is a consumable vegetable oil got from the monocarp (ruddy mash) of the product of the oil palms. The major objective is to provide a cheap and effective alternative to diesel. This paper is an exploration of the capability of the palm oil as a practical, modest and effective hotspot for the generation of biodiesel. the paper is based on the characterisation of palm oil compare to diesel.
