A layout design method for an industrial park based on a novel arrangement algorithm – Consideration of pipe network and multiple hazard sources

Abstract

The general layout design of an industrial park has a significant impact on safety, transportation, piping, and land occupation. Currently, the relevant studies are not mature, and most of the practical designs heavily rely on expertise. In this work, an optimization methodology is proposed to consider safety, piping connection, and occupied land simultaneously for the layout problem. An improved FLUTE algorithm is developed to optimize the pipe network arrangement. Quantitative risk analysis is employed to describe the safety aspect and the interaction among multiple hazard sources. A continuous model is used rather than a grid model to describe occupied land. The first case study illustrates that the improved FLUTE algorithm can find a better pipe network connection compared to previous algorithms with up to 38% reduction of cost. In the second case study, the layout-relevant cost from the proposed model is 6.3% lower than from a previous model, and the effectiveness of the model for multiple hazard sources is also illustrated. A Monte Carlo simulation is employed to test the optimal layout obtained from the proposed model. The results indicate the feasibility and the acceptability of accident consequences of the obtained layout. Consequently, the proposed model can significantly enhance safety and reduce capital cost for an industrial park.
