Risk Models for Hazardous Material Transportation Subject to Weight Variation Considerations

Reasonable risk models in hazardous material transportation are of practical significance, for safeguarding the lives and properties, protecting natural environment, facilitating sustainable development. The existing can be classified into summation maximum models, which result overreliance on overall or local risk. To overcome these problems, this article, we present two novel considering different aggregation methods risks. first model is supported by an ordered weighted averaging (OWA) operator, assigns weights according to position segment process aggregation, second state variable weight (SVW) vector, adjusts segments change values. Generally speaking, OWA used under situation with complete weighting information, whereas SVW could incomplete information. Based analysis mechanism, show that both effectively balance risks assisted variety. Numerical experiments provided illustrate validity proposed models.
