Recently, many construction firms fall on hard times because construction business continues to stagnate. In this paper, we analyze the efficiency of the listed construction firms using a combined AHP and DEA model. In order to determine the input and output factors of DEA, the AHP model is applied to evaluate the importance of input and output factors. The benchmarking companies and efficiency value for the construction firms with inefficiency are also provided to improve the their efficiency. We analyzed the 57 listed companies consisted of 36 listed on KOSPI and 21 listed on KOSDAQ at the end of 2009. The analysis results show that eleven companies whose values of CCR are 1, and fourteen enterprises whose values of BCC efficiency are 1. In additions, the eleven firms have the scalability efficiency. Finally, we test the correlation between efficiency and the stock price and the correlation coefficient of efficiency group is 0.7 in the CCR model.

This study aimed to identify priorities in community pharmacist's roles in aged society using Analytic Hierarchy Process. We developed a survey questionnaire for AHP, which consisted of 19 pharmacist's roles selected from the FIP/WHO guidelines. The AHP survey questionnaire was self-administered by 127 pharmacists. The results showed that pharmacists put medication therapy management at the highest priority, preparation, dispense, distribution of medication at the second priority, and efficient healthcare system at the lowest priority. Among the 19 roles, new roles such as monitoring of medication therapy results, team-based health care, and transitions of care obtained relatively high priority.

Two perspectives on developing better decision capabilities for a warranty system can be identified: one involving the inclusion of a 'learning' module and the other the inclusion of a 'prioritization' capability. This paper demonstrates how a warning process can be included in a warranty system by coupling with a neural network's learning capabilities. In addition to the neural network, a method is employed for assigning priorities to warning criteria by using the analytic hierarchy process (AHP). Thus, it is possible to construct an integrated system with three components: the warranty system, the AHP module, and the neural network system. A case study is provided to enhance the accuracy of warning/detection judgment in a warranty system for automobile companies, having many factors related to the warranty system.

The cities keep growing due to industrialization and the risk of disaster gets higher as the society gets sophisticated. The center of current disaster plan has spent more efforts on post processing of disaster and it is the current status that the plan for shelter that minimizes the life and property damage has not been established effectively. Especially, the whole area of Noksan Industrial Complex at Noksan-dong, Gangseo-gu, Busan Metropolitan City was designated as danger area of tsunami, but the shelter has not been selected. Thus, this paper is willing to select the shelter using AHP analysis and GIS method that is multi criteria decision making analysis after grasping the buildings that can be selected as the shelter.

This study aims to derive primary policy challenges for the continuous diffusion of the smart work centers in the public sector by using the AHP survey. The policy challenges in the AHP survey were categorized into three aspects, namely technology, system, and awareness. The technology sector was divided into the improvement of smart work-related ICT and the facility improvement in a smart work center. The system sector was divided into the legal system and implementation system. The awareness sector was divided into organizational culture and individual awareness. Among total 12 policy challenges, the results of the AHP analysis showed that the improvement of the organizational culture was the policy issue of the highest priority in terms of importance and urgency.

IT Outsourcing has been take place for ages and its range has expanded. The cases are also often take place more but there are a few criteria for making decision of IT outsourcing project. Companies tend to take IT outsourcing as a trend or to follow competitor's IT outsourcing project. This study suggests the criteria for IT outsourcing project before going into the project. The criteria ate to describe what function of the companies need to take outsourcing. Research model is driven by Statistics and AHP method. Also, variables are presented for clear making decision. This model allows the companies find proper IT outsourcing type and conveniences.

This study started from recognizing the problem that neither the identity nor the role of records managers is clarified enough. Therefore, this study identifies the function of the records managers and how it should be carried. The method of functional analysis was used to collect information, and then the AHP method to analyze te core functions of the records managers. As a result, core functions were identified as follows: records management policy making, education, production control, records schedule management, collecting, transferring, description, appraisal, de-accessioning, records center management, disclosure, perusal service, and records management system. Therefore, this study presents that identity and role of the records managers as well as the priorities of the job.

This paper analyzes the problems of existing CCTV and discusses cyber security problems of IP-CCTV in cloud computing environment. In order to reduce the risk of simply removing the risk associated with the provision of cloud services, the risk analysis and counter-measures need to be carried out effectively. Therefore, the STRIDE model as the Threat Risk Modeling is used to analyze the risk factors, and Analytic Hierarchy Process(AHP) is used to measure risk priorities based on the analyzed threats.

The purpose of this study is to investigate the empirical results of Analytic Hierarchy Process/Data Envelopment Analysis-Assurance Region(AHP/DEA-AR) by using multiple regression analysis during the period of 2009-2012 with 5 inputs (number of gantry cranes, number of berth, berth length, terminal yard, and mean depth) and 2 outputs (container TEU, and number of direct calling shipping companies). Assurance Region(AR) is the most important tool to measure the efficiency of seaports, because individual seaports are characterized in terms of inputs and outputs. Traditional AHP and multiple regression analysis techniques have been used for measuring the AR. However, few previous studies exist in the field of seaport efficiency measurement. The main empirical results of this study are as follows. First, the efficiency ranking comparison between the two models (AHP/DEA-AR and multiple regression) using the Wilcoxon signed-rank test and Mann-Whitney signed-rank sum test were matched with the average level of 84.5 % and 96.3% respectively. When data for four years are used, the ratios of the significant probability are decreased to 61.4% and 92.5%. The policy implication of this study is that the policy planners of Korean port should introduce AHP/DEA-AR and multiple regression analysis when they measure the seaport efficiency and consider the port investment for enhancing the efficiency of inputs and outputs. The next study will deal with the subjects introducing the Fuzzy method, non-radial DEA, and the mixed analysis between AHP/DEA-AR and multiple regression analysis.

This study tired to develop the web credibility evaluation model by calculating weighted values and sensitivities of indicators which presented on preceding researches using Analytic Hierarchy Process. "Expert Choice 2000" was used as the tool for analysing AHP. 25 experts are answered for this questionnaire who are selected by judgement sampling method, one of the non-probability sampling method. Also, sensitivity analyses was performed to graphically see how the alternatives change with respect to the importance of the indicators or sub-indicators. The main results are summarized as followings; i) importance analysis in first level factors: trust-worthiness(0,606), expertness(0.222), safety(0.173), ii) importance analysis in second level factors: trustfulness (0.519), reputation(0.087), usefulness (0.102), timeliness(0,093), competency(0.027), security(0.115), reliability(0,058). iii) some of the importance analysis in third level factors: the site provides comprehensive information that is attributed to a specific source(0.252), the site has articles that list citations and references(0.153), the site contains user opinions and reviews(0.072), etc. iv) sensitivity analyses showed that the importance of the indicators or sub-indicators are slightly changed with respect to the alternatives change.
