The aviation industry is one of the most widely used applications in transportation. Due to the limited capacity of aircraft, revenue management in this industry is of high significance. On the other hand, the hub location problem has been considered to facilitate the demands assignment to hubs. This paper presents an integrated p-hub location and revenue management problem under uncertain demand to maximize net revenue and minimize total cost, including hub establishment and transportation costs. A fuzzy programming model and a genetic algorithm are developed to solve the proposed model with different sizes. The mining and petroleum industry is used for case studies. Results show that the proposed algorithm can obtain a suitable solution in a reasonable amount of time.

“…The last phase of RL is the recycling and remanufacturing of construction products, which has been mostly examined from an industrial process and logistics perspective. Similar to manufacturing in FL, most of the remanufacturing discourses in the construction industry is only featuring concrete mixtures and aggregates (NoParast et al, 2021;Sinha et al, 2010). Other construction materials and products are less explored.…”

“…Literature from both phases largely focused on the concrete industry. This could be because concrete is the most prominent material in the built environment by volume, which also involves a construction-exclusive supply chain that is easier to trace (NoParast et al, 2021). On the FL side, prefabrication supported by BIM and Lean production is seen as the most effective solution to improve CE performances (Bataglin et al, 2020;Ma et al, 2021).…”

“…One should note that the production of Portland cement is extremely impactful since each ton of produced Portland cement uses approximately 1.5 tons of raw materials and between 4000 MJ and 7500 MJ of energy, in addition to the emission of about a ton of CO2. Thus, Portland cement is recognized as a major source of CO2, being responsible for about 80% of the total CO2 emitted in concrete production (DOSSCHE et al, 2016;NOPARAST et al, 2021).…”

The objective of this research was to evaluate the use of the Life Cycle Assessment methodology to assist decision-making in structural projects of reinforced concrete. Were studied structural models for an eight-story building, with classes of compressive strength (fck) of concrete ranging from 25 to 50 MPa. Also, were evaluated changes in the dimensions of structural elements, as well as the consumption of component materials of the structure. Results showed that the structural models for classes C40 obtained the best results for 67% of the categories of potential impacts assessed, with potential impact values ranging from 7.4% to 21.2%, including the possibility of saving 18 thousand kg of CO2 emitted. After carrying out an economic analysis, was observed that the structural model for the C40 concrete presented the optimal environmental-economic solution. The results of this research indicate the feasibility of using the Life Cycle Assessment methodology and economic analysis as tools to assist in decision-making during the design process of reinforced concrete structures.
