Description: The ways of solving the task of optimizing the characteristics of civil defense shelters based on criteria compromise to reduce losses population and the cost of shelter per harboring human. Alternatively solving task as disciplining conditions applied value allowable losses and increasing cost efficiencies of funds for each stage of construction of shelters. A search for the optimal values of the characteristics of shelters under which funds will be spend efficiently, i.e. will be provided with a minimum overall losses among the population.
Keywords: shelters, optimal test, cost, expenses, the optimal values
