The Measurement Varying Weight Evaluation of Unascertained Threats from Air Targets in Key-point Air Defence
Yu Wang · Systems Engineering - Theory & Practice · 2003
The assessment of the extent of threat from an air raiding target, as one of the central problems in the decision of air defence command, involves many uncertain factors and some other qualitative factors which are hard to determine in guantity. These problems reflect uncertainty, or unascertainment of the decision-maker in his subjective thinking. Although the air raiding target has its definite task, the information available is not enough for the decision-maker to determine its intention and extent of threat to our defence points. By applying the unascertained measurement theory, the unascertained measurement functions conforming to non-negativity-normalization and additivity are presented. On this basis, a model of assessment sequence is set up to more precisely make out the extent of threat from assessed air target. The model is reasonable in design, high in resolving power, simple but precise effective in calculation. At the end, the model is successfully applied to the assessment of an air situation.
