As the Long-life certification system is recently introduced in the Housing Law in Korea, it is expected that an application of the lightweight wall panel will be increased in apartment construction as the main wall system. However, the performance criteria for lightweight wall is in the early phase of its action. Therefore, it is necessary to establish the performance criteria properly by investigating performance requirement in the user's perspective. The purpose of this study is to identify of the weight of the required performance items for the lightweight wall in apartment house. To analyze the priority in the performance, an interview survey is performed; after monitering the test-bed of the lightweight walls, user and experts evaluate the performance requirements. The weight of the performance requirement is developed by AHP method.

ITS (Intelligent Transportation System) has been more popular but ITS project managements remain complex because of diverse stakeholders and multidisciplinary processes of ITS. The multidisciplinary process enforces specialized competencies on ITS project managers comparing to other system integration project managers. In this paper, we derived core competencies of ITS projects from previous researches, built the hierarchy of the competencies, and employed AHP (Analytic Hierarchy Process) surveying ITS project managers and auditors with the hierarchy. Finally, we analyzed the difference of evaluation model on ITS project manager between project managers and auditors using Mann-Whitney U test. Additionally we suggest a method of building MECE (Mutually Exclusive and Collectively Exhaustive) structure for AHP using the HoQ (House of Quality). We expect our model to give some inspirations for raising capable ITS project managers and selecting a proper project manager for an ITS project.

Domestic residential buidling grading is currently comprised of 5 fields; sound-proofing, structure, ambient condition, living environment and fire-proofing. However, factors the take up most of the civil complaints are related to leakage, and waterproofing is not listed as part of the grading system. In particular, the Ministry of Land and Transport claims that the most crucial problems are leakage related in residential structures. Therefore, this study proposes to provide such grading system for waterproofing by AHP methodology based on waterproofing application locations in residential structures.

Recent recommendation systems are developing toward the utilization of high-dimensional data. However, high-dimensional data can increase algorithm complexity by expanding dimensions and be lower the accuracy of recommended items. In addition, it can cause the problem of data sparsity and make it difficult to provide users with proper recommended items. This study proposed an algorithm that classify users' subjective data with objective criteria with fuzzy-AHP and make use of rules with repetitive patterns through fuzzy association rules. Trying to check how problems with high-dimensional data would be mitigated by the algorithm, we performed 5-fold cross validation according to the changing number of users. The results show that the algorithm-applied system recorded accuracy that was 12.5% higher than that of the fuzzy-AHP-applied system and mitigated the problem of data sparsity.

This article is an exploratory empirical study on the introduction of the Electronic Shelf Labels (ESL) system, which is spreading to offline stores as a new price information system for retail stores in Korea. In order to conduct this study, eight measurement items were derived from the IT-BSC perspective as performance factors, and the AHP technique was used as a method for relative evaluation of priorities among the items. The survey, which was conducted for about 1 year and 6 months, examined changes in store employees' perceptions of performance factors before and after the introduction of the ESL system. The results showed that there were differences in high priority items between before and after introduction. This study suggests academic implications in that the AHP technique is used to measure the change in the perception of post-performance and expectation factors for products and services, and this study also suggests practical implications by raising the need for continuous improvement of products and services for customer value propositions that change with the maturity of the experience.

Purpose: To develop efficient PL response system, SMEs should decide which component of PL response system is important and implemented with priority under limited resources. To accomplish this goal, we propose strategic priority components of PL response system for SME manufacturer. Methods: We categorize the components of PL response system based on prior research results - System, Organization, Training, Technology, Cost, and Awareness. AHP (Analytic Hierarchy Process) is applied to extract important components of PL response system, which is used in assigning the priority of component. To analyze effects of each components, performance sensitivity analysis is applied. Results: The survey analysis results show Technology is the most important components. Organization and Cost component are follows. As the importance of Technology is changed, we can find Organization, Cost is second and third important components. Conclusion: Our research shows Technology which is related to make a safe product with systematic process, is a basic enabler of PL response system. Also, building a PL team and securing a budget for PL activity should be carry out with limited resources.

Current domestic safety training in building demolition works are heavily relies on the limited number of experienced people and thus, it implies the demand of preparing the systematic program and stricter yardstick is soaring. Questionnaire survey and in-depth interview results with demolition engineers were analyzed adopting AHP methodology. Analysis results reveal that the most urgent items which required improving current safety training system are to increase investment level, prepare more structured training system and secure experts, and so on. In addition, field labors and managers strongly requested the improvement of environment-related safety matters. Based on the evaluation results, guidelines were suggested for the improvement of safety training system in building demolition works.

In this research, we propose a hybrid group decision support mechanism (H-GDSM) based on Fuzzy AHP (Analytic Hierarchy Process) and FCM (Fuzzy Cognitive Map). The AHP elicits a corresponding priority vector interpreting the preferred information among the decision makers. Corresponding vector was composed of the pairwise comparison values of a set of objects. Since pairwise comparison values are the judgments obtained from an appropriate semantic scale. However, AHP couldn't represent the causal relationship among information, which were used by decision makers. In contrast to AHP, FCM could represent the causal relationship among variables or information. Therefore, FCMs were successfully developed and used in several ill-structured domains, such as strategic decision-making, policy making, and simulations. Nonetheless, many researchers used subjective and voluntary inputs to simulate the FCM. As a result of subjective inputs, it couldn't avoid the rebukes of businessman. To overcome these limitations, we incorporated the Fuzzy membership functions, AHP and FCM into a H-GDSM. In contrast to current AHP methods and FCMs, the H-GDSM method developed herein could concurrently tackle the pairwise comparison involving causal relationships under a group decision-making environment. The strengths and contributions of our mechanism were 1) handling of qualitative knowledge and causal relationships, 2) extraction of objective input value to simulate the FCM, 3) multi-phase group decision support based on H-GDSM. To validate our proposed mechanism we developed a simple prototype system to support negotiation-based decisions in electronic commerce (EC).
