Lifecycle Costs for Energy Equipment: FMECA & Lifecycle Costing Models as “Decision Making” Tools for Cost Reduction During the Whole Equipment Life

Advanced FMECA Method Based on Intuitionistic 2-Tuple Linguistic Variables and the Triangular Fuzzy Analytic Hierarchy Process

“…Failure mode effects and criticality analysis (FMECA) is typically adopted to identify, evaluate, and reduce existing or underlying errors and failures in system designs or processes [1]. Due to its simplicity and high efficiency, FMECA has been widely applied in some industries, such as the nuclear, aerospace, transportation, and manufacturing industries [2][3][4][5][6][7][8][9]. In traditional FMECA [10][11][12][13], every failure mode is assessed using three risk elements: detection (D), severity (S), and occurrence (O).…”

Life cycle assessment and life cycle costing of an innovative component for refrigeration units

“…A vapour compression refrigeration system generally consists of a closed circuit including a compressor, a condenser, an expansion device, an evaporator and the interconnecting pipes (Oh et al, 2016). Industrial refrigerators require high investment and operating costs, and they are characterised by a long lifespan in which repairs and maintenances often occur (Brom et al, 2016). In view of its extended lifespan and of the huge consumption of energy and materials, the use phase of high energy-consuming equipment is particularly important for its sustainability assessment (Zhang et al, 2018).…”
