A Study on the evaluation method unmanned aerial vehicle response system through multi-criteria decision making method (Focusing on military security facilities) KIM JAE WOOK Department of Defense Acquisition Program Kwang-woon University Graduate School This dissertation is a study on evaluation methods related to the construction of an unmanned aerial vehicle(UAV) response system focusing on military security facilities in order to prepare for various attacks such as terrorism using UAVs that are being perpetrated around the world. The evaluation method presented here refers to evaluation items (second and third tier evaluation factors), evaluation indicators [weight (importance), priority], development of converted scorecards, evaluation points, etc. Currently, UAVs are increasingly used in various fields of civil, public, and military area due to rapid technological development and mass production. And UAVs are positioning themselves as asymmetric weapons by taking advantage of the advantages of low cost and high efficiency (low price, ease of use, stealth, etc.). Therefore, in order to prepare for UAVs attacks, it is necessary to present the required level (standard) for each evaluation element related to the construction of an UAV response system by experts by military security facility class (Class Ⅰ / Class Ⅱ / Class Ⅲ). A reviews of prior literature on UAVs has focused mostly on research overall technology trends, industry trends, and policy trends related to anti-drones (UAV response). It has also focused on what detailed equipment is needed for detection, identification, and neutralization, on which is the concept of joint air defense warfare. After all, there is no literature that studies the actual evaluation of the overall UAV response system-related requirements. In this dissertation, experts were questioned using the Delphi and AHP method. These are multi-criteria decision-making methods, to derive evaluation items and evaluation indicators. In order to apply the Delphi method, various prior literature were comprehensively analyzed to derive provisional evaluation factors. And the final evaluation items were derived through a questionnaire of a group of experts (30 people). Also, before deciding on the final evaluation item according to the results of the Delphi questionnaire, the content validity Ratio (CVR) of each evaluation element was checked to check for abnormalities. In addition, 30 experts questionnaires on the importance and priority of each evaluation factor (6 in the second tier and 26 in the third tier) were conducted using the AHP method. And the consistency ratio for the survey results was 0.1 or less, which is a reliable result. Composite weights were used to develop the conversion scorecard, which used the most common calculation method to calculate the relative importance by calculating the weights for each third tier using AHP (pairwise comparison) and then multiplying with the weights of the second tier.3) The weight of each second tier (6) is multiplied by 100% and then multiplied by the weight of each third tier (26) corresponding to the second tier [conversion score (composite weight) = (second tier weight ☓100%) ☓ third tier weight]. Military security facilities are the same concept as national important facilities, and are classified into class Ⅰ, class Ⅱ, and class Ⅲ according to the impact on national defense when destroyed or deprived by the enemy.4) As a result of analyzing whether there was a change in the perception of the expert group related to military security facilities "unclassified" and "classified" 3) Ahn, J. S, "Developing Evaluation Criteria for Historic Gardens Preservation Condition by Applying Delphi Techniqueand Analytic Hierarchy Process." Sungkyunkwan University Ph.D. thesis, 2010, p. 115. 4) R.O.K. MND, “Instruction No.2425 Defense Security Service Instructions”, 2020, p. 71, (Class Ⅰ / Class Ⅱ / Class Ⅲ) through an expert questionnaire, the following three things were identified. First, the priorities of the second tier (6) UAV response systems related to military security facilities were in the order of "detection > identification > neutralization > cyber protection > combat development support factors > integrated product support factors" regardless of "unclassified" and "classified" (Class Ⅰ / Class Ⅱ / Class Ⅲ) military security facilities. Second, according to the "unclassified" and "classified" (Class Ⅰ / Class Ⅱ / Class Ⅲ) of military security facilities, the weight value of each evaluation factor of the second tier (6) were analyzed in the order of 'Class Ⅰ > unclassified > Class Ⅱ > Class Ⅲ'. Third, the priorities of each evaluation element of the third tier (26) of each military security facility are also consistent, but the weight value of some evaluation factors are derived differently. For example, among the second tier detections by military security facilities (Class Ⅰ / unclassified / Class Ⅱ / Class Ⅲ), the value of the third tier small target evaluation factor was 8.145 / 8.336 / 7.827 / 7.509. The reason for this phenomenon is that the definition and facility standards for each military security facility were not informed in advance during the "unclassified" questionnaire of military security facilities using the converted scorecard (composite weight). So the expert group could not select accurate judgment criteria for the "target facilities" related to the construction of the UAVs response system. The academic contribution this disserations are thses "even if an expert group is formed so as not to be biased towards a specific group, the results differ depending on the importance of the facility when military security facilities are unclassified versus classified (Class Ⅰ / Class Ⅱ / Class Ⅲ)". The other practical contributions are "Presented a quantified evaluation method for building an UAVs response system. According to be protected the military security facilities (Class Ⅰ/Ⅱ/Ⅲ), the total sum of evaluation factors is derived differently that is Class Ⅰ > unclassified > Class Ⅱ > Class Ⅲ". It is necessary to establish a system so that expert opinions can be collected. Future research directions require in-depth research on cost-effective response systems (equipment deployment etc.) related to UAV response by military security facility class (Class Ⅰ / Class Ⅱ / Class Ⅲ) using quantified acquisition criteria such as importance and priority for each tier evaluation factors presented in this paper. |
