The study introduces a multi-objective optimization procedure for shell-and-tube heat exchangers, incorporating thermal, hydraulic, and mechanical constraints to ensure equipment durability. Implemented in MATLAB using genetic algorithms (NSGA-II), the method optimizes design variables while adhering to mechanical standards. Results validate the approach against literature examples, highlighting cost and performance improvements.

This study presents the application of the TRIZ methodology (Theory of Inventive Problem Solving) in the design of cylindrical spur gears. TRIZ is a systematic approach to innovation, using inventive principles to resolve technical contradictions. The work demonstrates how modifying tooth geometry through tool displacement can enhance bending resistance without significantly compromising the contact ratio. The results show that the proposed solution meets safety and performance requirements, validating TRIZ's effectiveness in gear design.
