Infrastructures in many countries experience accumulations of snow. On pavements, this causes unsafe conditions for road users. An alternative technology to snow plowing and de-icing consists of embedding near the ride surface ribbon-like elements that melt snow and ice due to the Joule effect as an electrical current is passed through the ribbons. This study dealt with the optimization of electrically heated pavements utilizing such ribbons. For this, a thermal model was mathematically outlined;it considered the 2D heat equation applied to a three-layered domain representing such pavement. The top boundary (i.e., pavement surface) was subjected to a heat flux representing weather effects, which were quantified with measured data obtained in the UK. A large number of cases were considered for the optimization: ribbon spacing and embedment depth, thermal conductivity of the top layer representing AC, and energy consumption of the ribbons. Amongst all cases, for the considered weather data, it was found that the optimal heated pavement consists of a ribbon spacing of 0.2 m, an embedment depth of 0.07 m with a thermal conductivity of 2.5 W . m(-1) . K-1 for the asphalt concrete. The developed thermal model is seen as a tool that engineers can utilize for the thermal design of heated pavements.

This paper presents a study focused on comparing optimization methods applied to three distinct lattice structure: Octet, FCC, and BCC. The comparison was carried out through a comprehensive review of the relevant literature using the Google Scholar database. Various factors were considered, including the additive manufacturing process and corresponding materials, the software used for structural design and simulation, the geometric parameters, and the improvement obtained. It has been observed that certain optimization techniques, such as the addition of struts, can enhance the energy absorption capacity of lattice structures by increasing their relative density. In comparison, methods such as curved lattice designs were found to alleviate stress concentrations at the nodal points, leading to a more uniform stress distribution. Furthermore, the study highlighted that utilizing 1D elements in simulation analyses significantly reduces computation time while preserving result accuracy.
Recently, intelligent computation algorithms have been extended into every field, and the trend of digitization and intelligence in the decision-making system of supply chain management is becoming more and more obvio...
