Manufacturing Sustainability Assessment Comprising Physical and Mental Workload: An Integrated Modified SVSM and AHP Approach

Abstract

Sustainable manufacturing is critical today because it incorporates economic, environmental, and social factors into the manufacturing process. This research proposes a new framework for assessing manufacturing sustainability, including physical and mental workloads. The analytical hierarchy process (AHP) method is proposed to determine the weight of the triple bottom line (TBL) indicator. Each TBL indicator is evaluated for efficiency before being integrated into the sustainable value stream mapping (VSM) and traffic light system (TLS). Time, quality, raw materials, energy, water consumption, mental workload, and physical workload are the seven indicators used in this study. The framework proposed is applied to a case study in the plastics industry. The results show that the proposed framework can solve industrial problems. The manufacturing sustainability score in this industry is 75.06%, indicating that the company has moderate performance and needs improvement. In addition, this study includes implications and recommendations.

Value stream analysis of a waste picker cooperative

“…Preliminary studies have proposed numerous adaptations to Lean tools -especially Value Stream Mapping (VSM) -to meet sustainable objectives in different organizations (Bait et al, 2020;Hartini et al, 2020;Hedlund et al, 2020;Lima et al, 2023;Lorenzon et al, 2019;Mubin et al, 2023;Santos et al, 2019;Texeira et al, 2021). However, despite the efforts of the authors of this study, no research was found that dealt with the application of the use of VSM in pickers' cooperatives, making this study an important contribution to the literature.…”

Integrated Model of Lean and Risk Mitigation for Sustainability Performance Measurement in the Lubricants Manufacturing Industry

“…The application of lean manufacturing supports the achievement of green practices and vice versa. Sustainable manufacturing is a process that minimizes adverse environmental impacts, ensures worker safety, and has a positive long-term impact on the economy during the production process (Mubin et al, 2022). Sustainable manufacturing not only focuses on environmentally friendly production systems but also involves social responsibility with a wider scope, considering lean practices as part of sustainable manufacturing (Joung et al, 2013).…”

“…Furthermore, mapping the production line at each workstation assists decision-makers in making sustainable decisions. Thus, the industry requires a comprehensive methodology to map and measure manufacturing sustainability performance at the production level (Mubin et al, 2022).…”

“…Previous studies have utilized SVSM to measure and map manufacturing sustainability performance, such as Hartini et al (2020), who proposed an MSA assessment framework based on SVSM and Delphi-AHP for the furniture industry. Similarly, Mubin et al (2022) suggested using SVSM and weighting it with AHP, while also incorporating indicators of mental and physical workload in the plastics industry.…”
