Recently school food service operations are confronted with the wide spread pressures for accountability and the need to increase productivity. This paper is concerned with the make-or-buy decision framework for school food service systems considering the multi-attributes in the decision making. For the purpose of considering the multi-attributes analysis method in decision making for the school foodservice, we developed a make-or-buy decision framework using the multi-attribute analysis method, analytic hierarchy process, AHP method for school food service system. Finally, we developed a systematic and practical solution builder for a three-step decision support system in the view of 1) brainstorming for the idea generation, 2) analytic hierarchy process, AHP as a multi-attribute structure ed analysis method, and 3) aggregation logic model to integrate the results of reviewers. We developed web based program and applied it to a school foodservice problem.

Every public agency governing infrastructure has to plan effectively for rehabilitation of existing facilities within the constraints of the capital program. Numerous technical, social, political, financial, and management constraints govern the decision to rehabilitate a facility. However, without a systematic procedure for selecting facilities for rehabilitation, within the prevailing constraints, it is possible that the funds available for rehabilitation might be suboptimized. Therefore, a decision support system that assists the user in selecting facilities for rehabilitation while considering the technical, social, financial, and political and management constraints will be useful in the decision-making process. This paper compares the Analytical Hierarchy Process (AHP) with the Swing Weight method used to prioritize functional criteria for suburban station rehabilitation. This paper also contains a brief discussion about the relevance of the Multi Attribute utility theory in developing a decision model for the problem at hand. The results of this paper provides the user with a decision support system that would prioritize the stations in order of their weights obtained by a systematic evaluation of various criteria and sub-criteria involved in the decision making process

This study identifies communication patterns of groups using Instant Messenger for their group decision-making, and examines how these patterns are associated with creative solutions to problems. Our research suggests that certain communication behavior of groups, when appropriately organized, can be of help in enhancing creative production of outcomes. A qualitative study was conducted on communication patterns based on an analysis of text-based electronic conversation protocols. Specifically this research tried to overcome existing studies on electronic groups by focusing on interactive process of communication among participants. The major study conclusions are: (1) Satisfation of group decision-making may depend on the process or sequence of discussion among group members with Instant Messenger. That is, proper interactive responses and appropriate control of the discussion process are essential to obtain a high level of performance. (2) It is important to ]mike discuss rules based on meta-cognitive and interactive protocols in the early stage. Explicit rules relating to internal group processes as well as communication medium use are even more important to groups with Instant Messenger than face-to-face groups.

본 연구에서는 공공조직에서의 공무원들을 대상으로 업무수행과정에서 상사에 대한 신뢰가 조직유효성 요인인 조직몰입과 의사결정참여 그리고 직무성과에 어느 정도 영향을 미치는지, 이러한 신뢰와 조직유효성이 세무공무원과 일반공무원에 있어서 차이가 있는지를 실증적으로 검증한 연구이다. 검증결과, 세무공무원과 일반공무원 모두 상사에 대한 신뢰가 높을수록 조직의 몰입도와 직무수행에 관련한 의사결정의 참여도 그리고 직무성과에 높은 영향을 미치는 것으로 나타났다. 신뢰와 조직유효성이 세무공무원과 일반 공무원들에 있어서 차이가 있는지에 대한 분석결과는, 상사신뢰는 세무공무원이 높은 것으로 나타났으며, 조직몰입은 일반공무원이 높은 것으로 나타났다. 의사결정의 참여정도에 대해서는 세무공무원이 높았으나 통계적으로 유의하지 않았고, 직무성과는 세무공무원이 높은 것으로 나타났다.

도심지 건설 프로젝트에서 적정한 기초공법을 선정하는 것은 매우 중요한 의사결정 중 하나이다. 그러나 아직도 적지 않은 프로젝트에서 단순히 과거의 경험이나 숙련된 기술자의 의견에 기초하여 기초공법을 선정하고 있다. 본 연구에서는 기초공법결정과정을 보다 선진화하기 위해 계층분석법(Analytic Hierarchy Process; AHP)과 선호도함수(Preference Function; PF)를 이용하여 적정 기초공법을 선정하는 의사결정지원시스템을 제안한다. 제안된 시스템에서 계층분석법은 평가기준 간의 상대적 중요도를 반영하기 위해, 또한 선호도함수는 의사결정자의 기초공법 적합도에 대한 선호도를 고려하기 위해 이용된다. 제안된 의사결정지원시스템을 기 수행된 프로젝트 사례에 적용해본 결과, 시스템이 도출한 기초공법과 전문가들이 현장에 대한 면밀한 검토 후 선정한 기초공법이 동일함을 알 수 있었다. 제안된 의사결정지원시스템은 건설현장에서 최적의 기초공법을 선정하기 위한 의사결정 시 매우 유용한 도구로 활용될 수 있을 것으로 기대된다.

According to growing interest in environmental quality with improvements of a standard of living site selection problems such as waste landfill sites, caused regional conflicts. This study investigates a waste landfill estimation method that was used to for storage, management, analysis and display of environmental information provided by geo-spatial information system(GIS) and analytic hierarchy process(AHP) as a decision-making method. If GIS is integrated with AHP, site selection problems of environmental hatred facilities shall be able to be very useful, because of AHP with flexibility which appropriately reflects opinions of the related group.

In a world where opportunities and chances are common, the phenomenon referred to as "generation maybe" describes people in their 20s and early 30s who are usually being indecisive. With the increase in breadth of information and choices, the number of people who are hesitant in deciding whether to purchase increases at a fast pace, as does the number of products and services targeting this group. In order to enhance our understanding of the phenomenon of consumer hesitation, this study explores contextual factors and consumer characteristics that affect consumer hesitation in the purchase decision-making process. Specifically, this study examines whether seven contextual factors, self-determination tendencies, and five decision-making styles influence consumer hesitation in the product decision making process. An online survey was administered to test our research questions. A total of 309 Korean consumers (female=48.9%) aged from 20 to 35 were surveyed. A regression analysis revealed that four contextual factors (product involvement, need for information on alternatives, relative price, and uncertain need), two sub-dimensions of self-determination (perceived competence and relatedness), and two decision-making styles (price seeking and advice seeking) have noticeable influences on consumer hesitation. We also found that the degree of consumer hesitation positively influences consumer post-purchase satisfaction. The study concludes with discussions and practical implications.

Business process reengineering(BPR) aims at a radical redesign of our business processes in order to achieve dramatic improvements in their performance. However, the fact that many BPR projects have failed hesitates the companies who have started to use BPR or who are planning to do so. Implementing a radical plan from a cross-functional perspective needs a more careful consideration of process vision, preventive measures and contingency plan. Our research suggests to use a visual decision making process (VDMP) in the development of a process vision and implementation plan. A BPR project of Carlson School of Management (CSOM) at the University of Minnesota is illustrated to show our suggested methodology.
