The entire life of the steel bridge was assumed to be 100 years. The focus of this assignment was on the substructure of the steel bridge, specifically the decking system. Different design options for the decking system were be analyzed using techniques such as life cycle inventory, life cycle cost analysis, and multi-criteria decision-making methods (MCDM) to compare and evaluate the options.<\/p>\n<p>&nbsp;<\/p>\n<p><strong>LCA &amp; Multi-Criteria Optimization<\/strong><\/p>\n<p>Within the life-cycle analysis (LCA) the systems boundaries had to be defined as
