The sensitivity analysis of isolating switch´s life cycle cost

In the life of equipment, besides acquisition cost, there still is maintenance cost and disposal cost. Therefore, take sensitivity analysis to determine the parameters which influence the life cycle cost of equipment most is the most possible way to reduce the funds invested in equipments. However, the research of power corporation controlling cost in terms of life cycle cost is limited, and the selection of sensitive parameters is confined in regular range. This paper chose the isolating switch´s life cycle cost as evaluating indicator, made sensitivity analysis of life cycle cost model, and then determined the sensitive model parameters.
