To calculate the Life Cycle Cost (LCC), sum up acquisition, operating, maintenance, downtime, upgrade, disposal, risk, tax, insurance, and warranty costs. Present a breakdown of each phase's expenses, discounting future costs to present value for accurate comparison. Conduct sensitivity analysis to gauge LCC's sensitivity to key variables. Visualize data using charts or tables for clarity. Compare LCCs of different options to assess cost-effectiveness. This structured approach ensures stakeholders understand total ownership costs, facilitating informed decision-making regarding complex engineering assets.

If it’s a hydraulic system, wait until it breaks down and then back up a few hours. The fluid power industry adopted a run-to-fail (RTF) culture from its inception. It’s the most maintenance neglected capital intensive asset in most plants in America. Regrettably, when it does breakdown, which is inevitable, the cost to get it back up and running will add gallons of red ink to the cost of operation. An untrained person/s will replace major components that have nothing to do with the problem, and you will quickly add handsome profits to your overnight freight company. This while your production crew sits around twiddling their thumbs.

The cost does not always determine the selection; at times, the functionality of the equipment is as important as its monetary value. Putting a value on functionality is difficult compared to putting a value on a piece of machinery. Functionality is measured in labor savings, accidents not incurred, overtime not worked, people not having to be employed, etc. LCC falls short in justifying equipment in that aspect unless you use True Downtime Cost (TDC) metrics when identifying the cost of elements. Using TDC, functionality is pre-defined, resulting in more informed decisions. If your LCC is based on TDC, you can use your existing automation to collect TDC data, resulting in a world-class approach to LCC calculations and decision-making.

Más allá de la complejidad del activo a ser analizado, el LCC se calcula sumando los costos del proyecto de implantación del activo, partiendo desde los costos del proyecto en todos sus conceptos (ingeniería conceptual y detallada, compra del activo, instalación, commissioning y start up). Una vez en servicio, se debe considerar los costos de mantenimiento a lo largo de todo su período de funcionamiento. Finalmente, al cierre de su ciclo útil, se deben considerar sus costos de desinstalación y de disposición final. Muy importante hacer esta evaluación una vez transcurrido cierto tiempo de uso del activo, para analizar si es conveniente repararlo o eventualmente reemplazarlo por otro similar.

Ao coletar dados históricos sobre falhas de equipamentos, custos de reparo e tempo de inatividade, podemos usar métodos como a regress?o para prever custos futuros. Validar essas informa??es com padr?es do setor e consultar especialistas aumenta a confian?a nas nossas estimativas. Essa abordagem nos ajuda a tomar decis?es mais bem fundamentadas e a identificar oportunidades para melhorar a eficiência operacional. Além disso, documentar cuidadosamente as fontes e os métodos utilizados garante que todos os envolvidos entendam as suposi??es feitas e possam confiar nas análises apresentadas.

To estimate the life cycle cost (LCC) of a complex asset, identify all costs from acquisition to disposal. Break down costs into categories: acquisition (design, procurement, installation), operational (energy, labor, consumables), maintenance (routine, unscheduled, upgrades), and disposal (decommissioning, environmental remediation). Develop cost models using historical data, apply discount rates for future costs, and consider risks and uncertainties. Sum all present-value costs to get the total LCC, and regularly review and update the estimate. Estimating LCC for a power plant includes costs for design, construction, fuel, operations, maintenance, and decommissioning, adjusted for inflation and potential regulatory changes.
