Dynamic Design Optimization (DDO) of various engineering problems exhibit multiple optima in the feasible domain. Such problems can be posed as complex multimodal optimization problems. Application of traditional optimization techniques to such problems is computationally expensive with a high risk of getting trapped into a local optimum. Similarly, Genetic Algorithms (GA) suffer from premature...

The transportation of hazardous materials is always accompanied by considerable risk that will impact public and environment security. As an efficient and reliable transportation organization, a multimodal service should participate in the transportation of hazardous materials. In this study, we focus on transporting hazardous materials through the multimodal service network and explore the haz...
