A physical protection system (PPS) is used for the protection of critical facilities. This paper proposes a structure analytic hierarchy approach (SAHA) for the hierarchical evaluation of the PPS effectiveness in critical infrastructure. SAHA is based on the traditional analysis methods "estimate of adversary sequence interruption, EASI". A community algorithm is used in the building of the SAHA model. SAHA is applied to cluster the associated protection elements for the topological design of complicated PPS with graphical vertexes equivalent to protection elements.

Globally the interest of large-scale structure has been increasing for the use in various social and cultural events. However various problems for building large-scale structure in South Korea are expected in terms of construction method and site management due to the lack of experience. Construction method and planning significantly affects on making decisions. There are only theoretical approach for constructing large-scale building in domestic with the limited experience of constructing constrained size structure. Through Analytic Hierarchy Process with experts, derived decision factors mostly used construction method in construction of large-scale structure. Derived factors from this study will support making decisions for field management in constructing large-scale structure.

This study proposes a new approach which combines Data Envelopment Analysis(DEA) and the Analytic Hierarchy Process(AHP) techniques to effectively evaluate Decision Making Units(DMUs). While DEA evaluates a quantitative data set, employs linear programming to obtain input and output weights and ranks the performance of DMUs, AHP evaluates the qualitative data retrieved from expert opinions and other managerial information in specifying weights. The objective of this research is to design a decision support process for managers to incorporate positive aspects of DEA's absolute numerical evaluations and AHP's human preference structure values. It is believed that a pragmatic manager will be more receptive to the results that include subjective opinions incorporated into the evaluation of the efficiency of each DMU efficiency. The WPDEA method provides better discrimination than the DEA method by reducing the number of efficient units.

Increase in population and its daily increasing in our today society results in an increase in housing demand while traditional methods are not applicable. The project preparation and realization processes, based on theoretical and empirical studies, a creation of goods, services, and technologies, are the most important human activities. Selection of effective technological systems in construction is a complex multi-criteria decision-making task. Many decision-makers refuse innovations once faced with similar difficulties. Therefore, using modern materials and methods in this industry is necessary. Modern methods increase quality and construction speed in addition to decrease energy consumption and costs. One of the problems in the way of any project is selecting construction system compatible with the project needs and characteristics. In the present research, different concrete structures such as common reinforced concrete (RC) structure, prefabricated, Insulating Concrete Formwork (ICF), 3D Panel and Tunnel Concrete Formwork (TCF) for buildings with limited floors in Iran are studied and compared from the viewpoint of different criteria like cost, time, applicability and technical characteristics with industrialization approach. Therefore, some questionnaires filled out by construction industry experts in order to compare criteria and sub-criteria in addition to evaluation of optimized structural systems. Then, results of the questionnaires ranked by Analytic Hierarchy Process (AHP) and the most effective alternative selected. The AHP results show that 3D Panel system 36.5%, ICF 21.7%, TCF 19.03%, prefabricated system 13.3% and common RC system 9.3% are the most and the least efficient systems respectively.

Fire is one of the greatest threats to historical buildings not only to the building's occupants but also to the building's structure and contents. The purpose of this research is to evaluate fire risk in historical buildings in Korea through a series of survey and review. In this research, a multicriteria decision-making approach involving Analytical Hierarchy Process has been designed to determine a weighted index to identify factors and quantify fire risk. Fire risk ranking systems of historical building has been developed in some applications, for example, BOCA, WISCONSIN, FSES and HFRI. According to the such derived fire risk indexing, the Human Activity index showed the highest risk, followed by Historic Buildings, Fire Safety Systems, and then Natural Environmental Causes. Comparison of these factors indicates that the derived risk values differ from case to case. It is proposed that a performance-based design approach should consider the building & occupant characteristics, locations and historical significance, resulting in a more accurate and effective evaluation of fire risk.

The changing business environment requires that firms reengineer their fundamental processes in order to retain their competitive advantage. Most Business Proess Reengineering (BPR) projects, however, have failed partly because the essential enabler, ie. information technology, was unable to perpetuate the original vision. The information systems were unable to support the collaboration among the workers participating in the process. Workflow Management Systems (WfMS) have the potential to enhance not only individual performance as did traditional information systems, but also the group performance essential to the success of BPR by providing an effective means of communications through connectivity. It also enhances productivitiy through proceduralization of the fundamental processes, thus making it possible to empower the employee even while it controls the flow, and ultimately the delaly that originally made the BPR effort necessary. Therefore, though it is not a panacea, WfMS's can improve chances for the success of BPR projects. Managers who have realized this are faced with another obstacle - that of selecting the WfMS that best meets the particular organization's needs. This paper provids an evaluation structure of WfMS functions with emphasis on those functions that are essential for BPR, classifying the functions into an attribute hierarchy according to the Analytic Hierarchy Process (AHP) approach. It also suggests specific evaluation criteria for the main workflow functions provided by most vendors today, thus providing managers with a comprehensive guideline to facilitate the decision process.

This paper is concerned with development of a multi-attribute structured decision model. In this study, we used AHP(analytic hierarchy process) and fuzzy set ranking methodology to overcome the multi-attributes structured decision problems ; such as multi-objective, multi-criterion, and multi-attributes. We proposed a 2-step approach : 1) individual evaluation and 2) integration of individual evaluations. In the first step, we define the performance factors and construct ana]isis structure, and in the second step performance evaluation by individual evaluators, and in second step, the results of individual evaluations are integrate. Also we developed a systematic and practical computer program to solve the problems according to the proposed methods. The proposed approach was known to be effective through a set of sample problems.

본 연구는 AHP를 적용하여 영양교사 및 영양사의 학교급식 식단 작성 시 고려 요인들의 상대적 중요도를 학교급별로 비교함으로써 효율적인 학교급식 식단 구성 방안에 대한 기초자료를 제공하고자 하였다. 모집단인 전국 유·초·중·고·특수학교 20,548개교를 대상으로 표본을 추출하여 총 395부 중 166부를 회수하였고, SPSS 통계 프로그램을 이용하여 CR이 0.2 이하인 응답에 대해 분석을 진행하였다. AHP를 이용하여 학교급식 식단 구성의 각 분야별 상대적 중요도를 분석한 결과 조리 인력 및 시설, 기호도, 영양의 균형, 조리 과정, 식재료 순으로 높게 나타났으며, 각 분야의 가장 중요한 하위 영역은 조리종사자의 숙련도, 급식대상자의 기호도, 영양소 섭취 기준, 위생, 식품비 예산이었으며, 이는 각 학교급에서 가장 높은 비율을 차지하였다. 더불어 급식 대상자의 기호도, 영양소 섭취 기준, 식품비 예산은 식단 작성 시 어려운 점의 상위 3가지 항목과도 일치해 식단 작성 시 반영이 어려울수록 상대적 중요도가 높게 나타남을 확인할 수 있었다. 본 연구는 향후 학교급식 식단 구성 및 관리 업무 효율 증대에 기여하며 정책 운영 방향 설정을 위한 기초자료로 활용될 수 있을 것으로 판단된다.
