We consider nonlinear nonconvex capacitated transportation problems where the nonlinearity occurs only in the last row of the transportation tableau. This transportation model can be successfully applied to economics representing the nonlinearity caused by penalties for unsatis®ed contractual quantities or by changing in price. An algorithm for local optimization, based on the algorithms for so...

The recent US Commodity Flow Survey data suggest that transporting hazardous materials (HAZMAT) often involves multiple modes, especially for long-distance transportation. However, not much research has been conducted on HAZMAT location and routing on a multimodal transportation network. Most existing HAZMAT location and routing studies focus exclusively on single mode (either highways or railw...

Transportation problem (TP) has its uses in real life because it versatile applications. Real-life problems are often uncertain due to which is difficult find the accurate cost. The fuzzy set and intuitionistic useful for handling uncertainty, but these also have some limitations. For that reason, this study, we worked on another of values called bipolar single-valued neutrosophic (BSNS) genera...

Around the world, particularly in North America and Australia, urban sprawl combined with low density suburban development has caused serious accessibility and mobility problems, especially for those who do not own a motor vehicle or have access to public transportation services. Sustainable urban and transportation development is seen crucial in solving transportation disadvantage problems in ...
