Method for effectiveness evaluation of underwater vehicles based on grey system theory

Aim. In our opinion, the existing Availability Dependability Capability (ADC) method for evaluating underwater vehicles takes into account only three influencing factors; it cannot meet the requirements of decision-making. We now present what we believe to be a better evaluation method for underwater vehicles. In the full paper, we explain in detail our evaluation method; in this abstract, we just add some pertinent remarks to listing the two topics of explanation; (1) the hierarchy structure for six main indexes of underwater vehicles; (2) the evaluation method of underwater vehicles based on grey system theory; under topic (1), we constructed the index system for evaluation in terms of mobility, detection, pursuit, anti-countermeasure, re-search and damage; Fig.1 in the full paper shows the index system; under topic (2), we describe the corresponding evaluation process in the paper; we employ Analytic Hierarchy Process (AHP) to calculate the weight of each index (subtopic 2.1); we obtain the sample matrix of evaluation (subtopic 2.2); we determine the grey levels of underwater vehicles (subtopic 2.3); we calculate the value of evaluation (subtopic 2.4). Finally we give an example for effectiveness evaluation of underwater vehicles, the results are given in Table 3 in the full paper; these results show that this evaluation method is feasible and reasonable.
