reliability estimatin of the gas export unit with two standby turbines based on the failure time data under the regression models

The gas export unit is a set of gas turbines which plays important and vital role in production of a gas refinery. a more exact estimate of the equipment (specially gas turbines) reliability helps managers to design the purposive maintenance planning. in this paper, some representations based on the concept of the minimal repair are given for the reliability function of the equipment. reliability of the equipment is estimated based on the quadratic and power law regression models as a non-parametric approach. also, reliability of a system(gas export unit) is explored under two standby components(turbines) based on the presented models. real practical examples are given to illustrate the proposed models.
