Route Optimization In The Removal Of Radiation Hazards

Route optimization is one of the types of jobs peculiar to nuclear facilities. For example, route optimization can be used as a way to minimize the radiation dose to personnel during the dismantling of dangerous radiation equipment. The sequence of jobs affects the total dose exposure of personnel. Also, in the solution of problems there are additional constraints in the form of precedence conditions. These conditions are due to technological constraints on the sequence of dismantling. This problem is similar to the well-known traveling salesman problem, but unlike the classic traveling salesman problem, the cost function depends on the list of outstanding tasks. A version of the method of dynamic programming has been designed to solve this problem and the appropriate software has been created. The developed software to provide estimates reduces personnel exposure in the optimization sequence of dismantling radioactive equipment.
