The 3E and 1L logistic model analysis
The 3E model integrated with 1L logistic models are developed to evaluate the interrelationships among energy, economic, environmental, and logistics factors. This comprehensive approach enhances the assessment of system performance by integrating logistics costs into the analysis framework. The final outputs of the 4E model include the levelized energy cost per life cycle assessment (LEnC) and the levelized energy cost per Logistics (LElnC). The levelized environmental and logistics impact (LEnlCA), along with energy and logistics assessment (EnA and EIA). The interrelationships among the four impact categories, energy, economy, environment, and logistics, are systematically analyzed through the procedural steps involved in developing the 3E and 4E evaluation models. Figure 1 presents the governing equations used in the modeling process, while Figure 2 illustrates the integrated 3E and 4E framework. A comprehensive description of each parameter and its corresponding role within the equation model framework is provided in Table
