Simplified model supporting decision-making considering the criteria of sustainable development and life cycle assessment (LCA)

where social, environmental, and economic considerations are key.
This is a difficult task, especially in the area of the following
economic and environmental changes, as well as changes in customer
expectations. Additionally, it has become crucial to make product
decisions that will be based on their entire life cycle (LCA). Although
these aspects of sustainability and LCA are popular, bringing them
together in one analysis remains challenging. Therefore, the article's
objective was to develop a simplified model that supports decisionmaking, taking into account the criteria of sustainable development
and life cycle assessment (LCA). The originality is the proposed
model, which operates based on a qualitative indicator (product
quality level), an environmental indicator (the product's impact on the
environment throughout its life cycle) and a price indicator (purchase
price of the product). These indicators are created using the TOPSIS
method and the modified ACJ-E method. As a result, a product
ranking is created. A novelty is the combination of Life Cycle
Assessment (LCA) criteria with quality criteria and the actual
purchase price of the product. The model test was carried out on the
example of CATERPILLAR mini excavators. However, the model
can be dedicated to any company that wants to make decisions in
accordance with the idea of sustainable development.
