A fuzzy decision support system for evaluating Lean-Green and company-specific production system

Area of Science:

• Industrial Engineering
• Environmental Management
• Operations Management

Background:

• Lean production focuses on waste elimination and continuous improvement in manufacturing.
• Growing environmental concerns necessitate integrating green production principles into business operations.
• Companies face increasing pressure to reduce their environmental impact.

Purpose of the Study:

• To evaluate a company-specific production system (XPS) within the tractor manufacturing supply chain.
• To examine the application of lean production aspects in the context of green production.
• To identify key criteria and elements for successful lean-green production implementation.

Main Methods:

• Case study of an original equipment manufacturer in the tractor industry.
• Evaluation of the company-specific production system (XPS) against lean-green production criteria.
• Analysis of relationships between XPS elements and lean-green production criteria.

Main Results:

• The company employs six lean-green production criteria: green packaging, quality improvement, waste reduction, pollution reduction, transport management, and cost reduction.
• Continuous improvement and integrated auditing were identified as the most critical elements.
• These elements showed the highest ranks in their relationship with XPS and lean-green criteria.

Conclusions:

• Integrating lean production with green manufacturing is feasible and beneficial in the tractor industry.
• Continuous improvement and integrated auditing are fundamental for achieving lean-green production goals.
• The identified lean-green criteria provide a framework for enhancing environmental performance in manufacturing.
