Life cycle cost of maintenance with different levels of automation (English)
At the Swedish Transport Administration two different maintenance strategies are practiced to keep cameras in road tunnels clean. The theory of Life Cycle Cost, LCC, is applied on maintenance depending on its Level of Automation, LoA, and is further developed. In the case of cameras, in Swedish road tunnels the processes demonstrate two different LoA. LCC is used to compare and analyze how the properties between semiautomatic and manual maintenance affect investment costs, operational costs and the cost of preventive and corrective maintenance. Semiautomatic cleaning maintenance of cameras in road tunnels indicate a larger LCC than manual maintenance. This is due to a larger investment cost for machinery, but a similar annual cost for preventive maintenance. The presented properties affecting LCC are placed in a general context. This emphasize the significance of examining costs at high level of detail and comprehend the properties causing the costs.
