In the GORRAM, the estimation of resource requirements for wartime equipment is based on the ELCON of the USA. The number of vulnerability groups of ELCON are 22, but unfortunately it is hard to determine how the 22 groups are classified. Thus, in this research we collected 505 types of basic items used in wartime and classified those items into new vulnerability groups using AHP and cluster analysis methods. We selected 11 variables through AHP to classify those items with cluster analysis. Next, we decided the number of vulnerability groups through hierarchical clustering and then we classified 505 types of basic items into the new vulnerability groups through K-means clustering.This paper presents new vulnerability groups of 505 types of basic items fitted to Korean weapon systems. Furthermore, our approach can be applied to a new weapon system which needs to be classified into a vulnerability group. We believe that our approach will provide practitioners in the military with a reliable and rational method for classifying wartime equipment and thus consequentially predict the exact estimation of resource requirements in wartime.

The purpose of this study is to understand the quality of University library service and to propose analyzing method from user's perspective. For that, this study noted that 'the process' of using the university library service rather than 'what did they use' in the university library. In-depth interview data about User's experiences that they used university library drew service quality elements based on the method of grounded theory. Comparing the derived service quality elements with LibQual+ dimensions, the result of this study is as follows. (1) Service quality element related to the user's emotion and new user-friendly service customization were shown. (2) Substantial claims of users were analyzed more specifically by this study. It seeks ways to differentiate service quality factors by attributes and priority importance about service quality elements which was analyzed using KANO and AHP.

Almost all Drivers who are not familiar with local areas usually rely on road signs equipped along the roadways. The road signs in Korea present the name of the city along the driver’s direction. The consistency of guided name on the road-signs is important for drivers. The discordances among road signs frustrate drivers particularly when the drivers are confused with whether or not they are in the right direction. There are several studies focusing on the continuity of information on the road signs. Most of the researches, however, do not suggest the objective way but diagnose present problem. Applying the Analytic Hierarchy Process (AHP), we evaluate the impact of information on road signs and select the candidate information considering the score and limited number of information. We also suggest the reasonable spatial influence area of road sign information using geo-spatial analysis. From this study, we expect that the director in charge of selecting information can make decision reasonably without difficulties of choosing information.

It is one of the most important decision making problems to select the adequate foundation practice for the downtown construction project. However the foundation practice has not been selected systematically yet by considering various construction field conditions in many projects. The foundation practice is often informally selected on the basis of only past experiences and skilled engineer's opinion. For making the selection process systematically, in this study, we propose a decision support system (DSS) for selecting foundation practices based on the Analytic Hierarchy Process (AHP) and the Preference Function (PF). In the proposed DSS, the AHP is used for making the selection process more reasonable and the PF is used for considering the decision maker's preference. To validate the proposed DSS, we apply the proposed DSS to the pre-performed construction projects. The application results show that the proposed DSS gives the same foundation practices with the implemented foundation practices that the skilled foundation engineers select after carefully analyzing construction field conditions. The proposed DSS can be used as a useful tool for making decisions to select the foundation practice in the construction fields.

In 1995 of May, the Ministry of Construction and Transportation (NOCT) developed the First Nation-wide Master Plan of GIS. It is set up in response to an increasing and various demands on spatial informations. Until now, a set of diverse projects related to spatial information have been proposed and executed. However, cost-benefit analysis of investment and decision making for alternatives have not been carried out appropriately because scientific evaluations for obtaining efficiency and economical validity of investment have been deficient. Optimum decision making for projects based on itemized priority order using effect or cost of proposed alternative plan is a fundamental expedient for demonstration of propriety of projects and enhancement of efficiency of investment. From such understanding, this paper applied the analytic hierarchy process (AHP) technique to the cost required to construct a GIS so that analyze the weight of each cost factor.

It is no exaggeration to say that we live with cyber threats every day. Nevertheless, it is difficult for us to obtain objective information about cyber threats and attacks because it is difficult to clearly identify the attacker, the purpose of attack, and the range of damage, and rely on information from a single source. In the preceding research of this study, we proposed the new approach for establishing Database (DB) for cyber attacks using Open Source Intelligence(OSINT). In this research, we present the evaluation factors for cyber threats among cyber attack DB and analyze the priority of those factors in oder to quantify cyber threats. We select the purpose of attack, attack category, target, ease of attack, attack persistence, frequency of OSINT DB, and factors of the lower layer for each factor as the evaluation factors for cyber threats. After selection, the priority of each factor is analyzed using the Analytic Hierarchy Process(AHP).

Recently construction environment is being professionalized. oversized and diversified. Due to fluctuation of construction environment, the demand for the project of steel structure is ieased gradually and steel construction is needed the efficient quality management. The construction of steel structure which required a variety of sub-contractors, the progress of works and technologies are comprehensive of various risks and uncertain factors. But currently the construction of steel structure is conducted the risk management by perception and experience of constructors. Therefore, the analyzing factors of the risk and establishing the device are able to manage the quality management efficiently. In this study, we have conducted the interview of experts, polls and through the Analysis Hierarchy Process (AHP) for the scientific and systematic risk management. This paper will propose a plan for systematization of the construction of the steel structure.

Due to the Internet and computing capability, new and variant malware are discovered around 1 Million per day. Companies use dynamic analysis such as behavior analysis on virtual machines for unknown malware detection because attackers use unknown malware which is not detected by signature based AV effectively. But growing number of malware types are not only PE(Portable Executable) but also non-PE such as MS word or PDF therefore dynamic analysis must need more resources and computing powers to improve detection effectiveness. This study elicits the pre-filtering system evaluation factor to improve effective dynamic malware analysis system and presents and verifies the decision making model and the formula for solution selection using AHP(Analytics Hierarchy Process)
