Abstract |
In order to address new problems in allocation-transportation of emergency supplies when direct paths and detour paths coexist in earthquake disasters, and to provide emergency managers with diversified decision-making schemes, an optimization model of allocation-transportation was developed aiming at minimizing sums of loss and time comparison effects. Secondly, by improving velocity and parameter update strategies of MOPSO algorithm, and incorporating a code modification strategy for modifying unfeasible solution to a feasible one, a MOPSO algorithm based on code modification (MOPSO-CM) was presented to solve the model. Finally, effectiveness of it and the algorithm was verified through numerical examples. The results show that the proposed model and algorithm can effectively solve new problems in allocation-transportation, and can provide multiple optimization schemes for emergency management decision makers. © 2020 China Safety Science Journal.
