Development and Optimization of a Condition-Based Maintenance Policy with Sustainability Requirements for Production System

Abstract

In the field of condition-based maintenance, maintenance costs and system reliability criteria are the primary considerations for traditional maintenance management. These methods lack consideration of the environmental impact caused by equipment degradation, such as excessive emissions and energy consumption. In addition, because equipment degradation has various impacts on the ecological environment, companies with excessive emissions and energy consumption can receive huge fines, making it of great value to study ecoconscious maintenance strategies. In this paper, we propose a condition-based maintenance strategy considering energy consumption and carbon dioxide emissions. The major objective of the research is to extend a model which integrates ecological aspects with maintenance decision-making and optimization. The simulation and sensitivity analyses conducted verify that the model proposed can minimize total costs, as well as the environmental impact.

Insertion of sustainability concepts in the maintenance strategies to achieve sustainable manufacturing

“…During the CM intervention, the costs associated with the lost production, labor force and spare parts are considered, which are classified as internal maintenance costs (RADHOUI et al, 2012;SARI et al, 2015;FRANCIOSI et al, 2017), as well as the environmental cost of carbon dioxide (CO2) emissions during CM, which is classified as an external cost of maintenance (FRANCIOSI et al, 2017). According to Jiang et al (2018), the emphasis on the economic dimension is due to the high internal and external costs resulting from CM compared to other maintenance strategies.…”

“…For the economic dimension, the same internal and external maintenance costs used to select the CM are considered (RADHOUI et al, 2012;SARI et al, 2015;MACCHI et al, 2016;FRANCIOSI et al, 2017;JIANG et al, 2018;XIA et al, 2018).…”

“…For the environmental dimension, the consumption of electricity, the amount of GHG emitted and the waste generated before and after the PM are environmental criteria employed (YAN; HUA, 2010;YILDIRAM, 2013;SANIUK et al, 2015;JIANG et al, 2018;XIA et al, 2018). For the social dimension, the criteria involve http://www.ijmp.jor.br v. 10, n. 6, November -December 2019ISSN: 2236 employee safety and health and stakeholder participation YILDIRIM, 2013;FRANCIOSI et al, 2017).…”

“…In this regard, these models evaluate the energy consumption and CO2 emissions during the monitoring of the equipment, as well as the influence of the costs of these ecological factors along with other maintenance costs (HOANG et al, 2016;JIANG et al, 2018).…”

“…In addition, Saniuk et al (2015), through in-depth research with companies in the foundry field that use sustainable criteria in the maintenance area, obtained: 20% savings in the use of raw material during production, 15% reduction in the consumption of electricity by equipment, 20% longer service life of lubricating oils and reduction of noise and emissions of pollutants by the machines. Others researches are developing methods that use sustainability criteria to achieve maximum productive capacity and equipment availability at the lowest possible cost, with emphasis on productive systems that adopt PM or CBM (YAN; HUA, 2010;RADHOUI et al, 2012;SANIUK et al, 2015;HOANG et al, 2016;FRANCIOSI et al, 2017;JIANG et al, 2018).…”
