Hazardous material (Hazmat) transportation is an inseparable section of the industry, despite its major financial and health risks. In order to optimize Hazmat transportation, a multi-objective routing model with time windows employed where risk distance are minimized. Due uncertainty risk, Z-number fuzzy approach used estimate in which probability occurrence severity considered context Z-infor...

Hazardous waste management incorporates collection, separation, treatment, recycling and disposal of hazardous wastes. In this paper, a new multi-objective mixed integer model is presented for hazardous waste collection problem. The model aims to minimize transportation and construction costs, and environmental and population risks in hazardous waste management systems. This model is applied in...

Dual-arm robotic system for load transportation in hazardous environments is considered in this study. First, physical model of the robot arms with the load is presented and related equations of motion are obtained. Friction forces arising on the contact points between the load and robot arm tips are also taken into account. Then, robust non-chattering sliding mode control is used in order to o...

In China, the Ministry of Transport stressed need to “Strengthen application active safety technology”. The transportation hazardous chemicals represented by LNG, LPG, and liquefied hydrocarbons is weak link in traffic safety. aim this study apply digital twin (hereinafter referred as DT) technology whole process handling (including loading unloading) help improve anti-risk ability road network...
