In general, equipment that facilitates product generation in a chemical process is termed the “front-end” unit. The units placed behind the front end form the “back end,” which are usually used for purification purpose. In any practical environment, it is impossible to avoid unexpected front-end failure(s) after a long period of continuous operations, and the back-end responses can often be adopted to mitigate the resulting harmful effects. Therefore, it is beneficial to figure out effective counter measures during the design stage for manipulating the back-end process against such hazards that are identifiable a priori. Our research objective is to conjecture a few remedial strategies to eliminate/reduce the effects of the front-end failures on the basis of sound engineering judgment, previous operational experiences, and rigorous simulation results. For convenience of illustration, the ethylene production process has been chosen as a working example. Although the procedures obtained with such a heuristic approach may not be as rigorous as those created by the fashionable tools nowadays, e.g., an AI agent, these proposed operations should at least be reliable and can be used as the basis for further improvements. Note also that this procedure synthesis strategy may be carried out much more quickly without the need to secure a large amount of training data in advance. Furthermore, the proposed approach may be extended to manipulate any other plant with the same process structure after front-end malfunction(s) develops. This generalizable feature is considered to be the most useful contribution of the present study.

Hydrogen, as an efficient and clean energy carrier, is confronted with significant challenges during road transportation due to its inherent risks of flammability, explosion, and easy diffusion. These risks not only pose high safety concerns but also bring substantial economic challenges. To address these issues and enhance transportation efficiency while ensuring safety, this paper proposes a novel multiobjective optimization model. This model integrates a combination weighting method with gray correlation analysis to quantitatively evaluate and optimize transportation paths. It comprehensively considers multiple critical factors, including population casualty risk, environmental diffusion risk, and economic loss risk, from the perspectives of safety, economy, and time. The model’s effectiveness in identifying high-risk paths and optimizing transportation decisions is validated through the calculation of an actual transportation network. The research results indicate that this method can effectively achieve multidimensional risk trade-offs, providing a safer and more efficient transportation path scheme. Moreover, it offers valuable theoretical support and practical guidance for risk management and path optimization in hydrogen road transportation.
