Fuzzy prioritization approach for risks of wind turbine life cycle

Recently, wind force which is renewable energy resource has been used widely throughout the world. Wind turbines are system which firstly, converts the kinetic energy of the wind into mechanical energy secondly mechanical energy change into electrical energy. Starting from the design and development phase of wind turbines till the establishment of and operate this system, this process includes too many risks in terms of occupational health and safety. For this study, the life cycle phase used is taken from1: design, development, manufacture, transport, construction, operation associated infrastructure, maintenance, repowering/life extension, decommissioning and waste treatment and recycling. Design and development phase relates to measures to be taken, rather than contain risk. Also related to waste treatment and recycling phase we have a few information about that contains risk. For these reason in this study these two phase is neglect. In this study we aimed at gain a prioritization of risks which exist during the life cycle of wind turbine. Prioritization of risk is very important in terms of to determine which steps should be taken further measures. For prioritization of risk is employed fuzzy AHP alpha-cut analysis method.
