摘要:
为确定危化品泄漏源的强度和位置，提出1种基于DE-NM算法的危化品泄漏源定位方法，以监测浓度与扩散模型计算浓度的误差作为优化目标，在差分进化过程中每隔一定代数执行单纯形法，使得二者误差最小的源强和位置即为最优定位结果。研究结果表明：DE-NM算法能够快速有效地反算出泄漏源的强度和位置，满足应急响应的要求；同时，能够避免DE算法的过早收敛，以及NM算法对初值敏感的问题，有效降低单一算法对定位结果精度造成的不利影响。
Abstract:
In order to determine the intensity and location of the leakage source of hazardous chemicals,a method for locating the leakage source of hazardous chemicals based on the DE-NM algorithm was proposed.Taking the error of monitoring concentration and concentration calculated by the diffusion model as the optimization goal,in the process of differential evolution,the simplex method was executed every certain algebra,so that the source intensity and location with the smallest error between the two were the optimal location results.The results showed that the DE-NM algorithm could quickly and effectively inversely calculate the intensity and location of the leakage source,so as to meet the requirements of emergency response.At the same time,it avoided the premature convergence of the DE algorithm and the sensitivity of the NM algorithm to the initial value,which effectively reduced the adverse effect of a single algorithm on the accuracy of the location results.
