What are the most common maintenance cost drivers and how can you reduce them?

A engenharia de manuten??o é fundamental para garantir a eficiência, seguran?a e durabilidade dos equipamentos e sistemas. No meu trabalho, eu aplico essa engenharia para prever falhas, realizar manuten??es preventivas e corretivas, e otimizar processos. Isso resulta em menor tempo de inatividade, redu??o de custos e aumento da produtividade.

Os custos de manuten??o com m?o de obra e paradas n?o planejadas s?o significativos para as empresas. Para reduzi-los, é fundamental investir em programas de manuten??o preventiva e preditiva, treinamento da equipe, tecnologias avan?adas de monitoramento e otimiza??o de processos. Essas estratégias ajudam a prevenir falhas, melhorar a eficiência do trabalho e minimizar o tempo de inatividade n?o programado, resultando em economias significativas a longo prazo.

Maintenance costs are often driven by inefficient processes, poor planning, and equipment failures. Identifying these areas and taking corrective action helps control expenses and improve reliability. ?? Track unplanned downtime and address root causes. ?? Optimize inventory levels to avoid overstocking or shortages. ?? Implement predictive maintenance to reduce reactive costs. ?? Streamline contractor management to improve efficiency. ?? Evaluate energy use and adopt energy-saving practices.

The main maintenance costs include downtime, spare parts, labor and lack of planning. To reduce these costs, I use Cost-Benefit Analysis (CBA) in the maintenance process. CBA allows me to assess whether maintenance actions justify the investment, prioritizing interventions that offer the greatest return. This helps me control costs by focusing on measures that really bring benefits, such as preventive maintenance.

CBA helps identify the most cost-effective maintenance strategies. 1. Resource Allocation: It guides the allocation of resources to high-impact maintenance activities. 2. Risk Assessment: It helps evaluate the potential risks and costs associated with different maintenance approaches.

Equipment Downtime: Unplanned equipment failure leads to expensive repairs and lost production time. Reduction Strategy: Predictive maintenance (PdM) using sensors and data analytics to monitor equipment health can help catch issues early before breakdowns occur.

1. Identify the Maintenance Project: Clearly define the scope and objectives of the maintenance project. 2. Estimate Costs: Calculate the initial investment costs, ongoing maintenance costs, and potential savings. 3. Identify Benefits: Determine the tangible and intangible benefits of the project, such as increased equipment reliability, reduced downtime. 4. Calculate Net Present Value (NPV): Evaluate the project's financial viability by comparing the present value of future cash flows to the initial investment.

Pasos para realizar un CBA en ingeniería de mantenimiento: 1. Definir el alcance y los objetivos del análisis 2. Identificar y cuantificar los costos: Costos iniciales Costos operativos Costos indirectos: Incluyen los gastos que no son fácilmente cuantificables. 3. Identificar y cuantificar los beneficios 4. Calcular el Valor Presente Neto (VPN) y la Tasa Interna de Retorno (TIR) 5. Evaluar los resultados y tomar una decisión Herramientas y recursos para realizar un CBA: -Hojas de cálculo electrónicas -Software especializado -Consultoría profesional

In my experience I have proven several times with practical real life data that Dr. Alan Wilson’s assertion that conservatively 42% of total maintenance cost is the maintenance labor cost. To manage maintenance labor cost organizations must focus on: 1. Labor Utilization Analysis and effective stewardship 2. Production and usage of a plant wide Maintenance Labor reporting guidance document.

Destaco la importancia de un enfoque técnico integral en la gestión de costos de mantenimiento. La codificación precisa de equipos y árboles de despiece por grupos funcionales y subsistemas constituyen cimientos esenciales para desglosar costos eficientemente. Garantizar la interrelación efectiva de centros de coste y la codificación detallada y valorada de repuestos, es esencial para una gestión transparente. La imputación precisa de la mano de obra, abarcando tiempos de actividad, paro y preparación, tiene que ser una prioridad.

Podemos elencar alguns pontos de impactos de custo, como falta de investimento em ferramentas de análise e diagnóstico mais recentes, déficit de capacita??o técnica, baixa utiliza??o efetiva dos recursos e n?o tratativa efetiva de falhas.

Unplanned downtime is the biggest maintenance cost driver. Unexpected failures disrupt operations, halt production, and lead to expensive last-minute interventions. Labor costs rise due to overtime and emergency scheduling, while sourcing parts becomes costly with expedited shipping or non-preferred vendors. In some cases, failures cause secondary damage, further increasing repair complexity. Preventive or predictive maintenance reduces these risks by identifying issues early, ensuring efficient resource use, timely parts procurement, and smoother operations with less financial impact.

Reducing Maintenance Costs with CBA: Material Costs: Optimize inventory management, negotiate better supplier contracts, and explore alternative sourcing options. Equipment Downtime Costs:Implement predictive maintenance, improve maintenance response times, and have spare parts readily available. Preventive Maintenance Costs; Energy Consumption

El presupuesto de mantenimiento se compone de 2 conceptos principales: 1) Los que se pueden considerar constantes (Horas Hombre y tareas planeadas de mantenimiento, con sus repuestos asociados). 2) Conceptos variables que son los costos de reparaciones por averías y las reparaciones no planificada, asociadas a la resolución de fallas o averías. Trabajar en una estrategia proactiva de mantenimiento consistente en un método de gestión ordenado, aplicando técnicas de mantenimiento predictivo y eventualmente con el uso de tecnología de industria 4.0 aplicada al mantenimiento permitirá tener bajo control las averías y trabajos imprevistos, lo que implicará una optimización del presupuesto de mantenimiento basado en un análisis CBA.
