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.

We propose a composite make or buy decision model considering both the transaction cost theory and the resource based view in the Korean defense industry using System Dynamics. We analyze relationship between core variables(transaction frequency, technological uncertainty, the level of technological dependency, technological level and acquisition ability for market information) and 'Make or Buy decision' focused on technological innovation capability. Based on the result, we propose the implications as follows : First, the defence industry needs more R&D investment. Second, it needs a balance between domestic(Make) and overseas(Buy) to increase the technological capability rapidly.

Recently a multi-attribute structure analysis method is one of the evident areas of important points in the decision support system analysis. This research developed an internet/intranet-based solution builder for a three-step decision support system using fuzzy-AHP in the view of 1) brainstorming far the idea generation, 2) fuzzy-AHP (fuzzy analytic hierarchy process) as a multi-attribute structured analysis method and 3) aggregation logic model to integrate the results of individual analysis. We applied this decision support system to the make-or-buy decision problem for school foodservice system considering the multi-attributes in the decision making. A computer program is developed and demonstrated it internet/intranet-based decision problem. It was known that this solution builder provides decision makers a good tool for mate-of-buy group decision making.

Strategic decision on the execution of national security improvement project is greatly important for the present and future national security. Though, the importance of strategic decision, decision making process has been executed under one-way thinking framework. This research provides a decision-making tool with make-or-buy approach for the national security improvement policy execution methods: foreign purchase and military R&D project, and, via simulation, confirms dynamic change of military capability index respect to change in ratio of foreign purchase and military R&D. A result shows that current ratio of foreign purchases and military R&D is insufficient for national security improvement policy goal. Applying the model from this research provides an appropriate ratio for short term and long term defense strategy and policy goal, and consequent result of increase in national security capability. Thus, this research model can be effectively utilized for national security improvement project.

This paper analyzes how IT adoption affects differently on the shippers' make-buy decision, depending on the changes through agency and coordination problems. Empirical findings are consistent with the theoretical predictions on the changes of shippers' decision, summarized as follows. First, while the adoption of agency-cost reducing IT leads to the increase in the proportion of private fleets, the adoption of coordination-cost reducing IT leads to the increase in proportion of for-hire carriage. Second, the extent of private fleets changes depends on the primary product type that trucks load, with products of important service task experiencing more increase. Third, the extent of for-hire carriage changes depends on the truck's trip distance, with long-trip trucks experiencing more increase. With the results, we present different policy implications from the conventionally advocated ones.

Even though many Korean consumers have bought environment-friendly fruits, including grapes and mandarins, farmers and suppliers still have little information about how they make a decision for the actual purchase in the real markets. Without the suitable information of purchase behavior of environment-friendly fruits, farmers and suppliers cannot set up the efficient marketing strategy which can create the better agricultural products for Korean consumers. The purpose of this paper is to analyze the consumers' purchase behavior of environment-friendly fruits in Korea. Especially, this study was focused on the grapes and mandarins, through the survey research and the frequency analysis. The results of study in this paper present a few findings useful as follows: First, Korean consumers have the strong concern of environment-friendly agricultural products, including fruits. Second, consumers usually buy environment-friendly fruits by two times per month. Third, consumers generally concern taste, freshness, and food-safety, when they buy environment-friendly grape or mandarin.

Purpose: The research aims to examine whether perception about busyness can affect the way people view themselves and then make an impact on purchase decision-making. Based on a proposed theoretical framework, the current research examines whether or not perception about busyness affects perceived self-worth and has an impact on impulsive buying. Research design, data, and methodology: The paper conducted a survey in which two scenarios are used for manipulating degree of busy mindset. For analyzing data, analysis of variance and regression analysis are applied, in conjunction with analysis of moderating effects. Results: Busy mindset has a positive effect on perceived self-worth. The effect of busy mindset on perceived self-worth is greater in the group of high perceived social mobility. In the category of hedonic products, perceived self-worth has a positive effect on impulsive buying intention. Conclusions: These results imply that a sense of self-worth can affect impulsive buying behavior on the basis that people sometimes buy things on impulse as a way of self-indulgence or self-reward for their efforts. Managerial implications of the results suggest a busy appeal to consumers would be more effective for hedonic products.

Purpose - Prior research has suggested that consumers typically prefer to have a larger number of options. However, preference of assortment size may depend on how depleted resources in consumers' mind are. Reduced capacity for self-regulation by resource depletion makes people rely on more intuitive and less effortful decision processing. When they are mentally depleted, people are likely to focus on the choice difficulty from large assortment, which leads to preference for the small assortment when they make a decision. It could be an important question potentially how being in a depleted mode through effortful self-regulation will influence on the evaluation of assortment size. To answer this questioner, we hypothesized that being engaged in self-regulation, as compared with not being engaged in self-regulation, will influence on the evaluation of product assortment size such as attractiveness, difficulty of choice, and anticipated regret. Research design, data, and methodology - In this study, we first manipulated self-regulatory resource availability using a self-regulation task (i.e., instructing participants to solve Sudoku puzzle vs. to solve diagram cube by filling any diagrams that they prefer into cube instead of number) and asked to indicate the difficulty of the tasks available to them ("How much difficulty did you feel when you complete the task?") Next, participants were asked to imagine that they were planning to buy a laptop at one of the two stores (small assortment: 6 options vs. large assortment: 30 options), both offering good quality of products. After reading the product descriptions, participants were instructed to consider all the information and choose a store that they would like to shop. Finally we measured the choice difficulty, evaluation of product assortments, and anticipated regret on a 7-point scale. We conducted two-way ANOVA in testing the main hypothesis that depleted consumers will show poorer subsequent self-control than non-depleted consumers when they make a decision in large assortment. Results - Compared with non-depleted participants, depleted participants showed the bigger difference from the degree of choice difficulty and product attractiveness between large and small assortments, but the result revealed only a significant interaction effect of resource depletion and assortment size on choice difficulty. Also depleted participants showed the smaller difference from the degree of anticipated regret between large and small assortments than non-depleted participants. Conclusion - Depleted individuals by a prior task are relatively effortless and intuitive form of choosing products so that they try to avoid making effortful trade-offs among choice difficulty such as large assortment, compare with non-depleted individuals. However, for anticipated regret, non-depleted individuals in small assortment anticipate more regret by excluding or at least restricting the possibility of buying attractive items or another kind of potential items than depleted individuals, regardless less choice difficulty in small option. To sum up, it is important to note that individuals are influenced by self-regulatory resources and their self-regulatory conditions contribute to the overall positive or negative impact of product assortment on choice.

오프라인 쇼핑몰에 비해 온라인 쇼핑몰은 빠르게 접근이 가능하기 때문에 처음 구매의사를 생성하고 실제 구매가 이루어지기까지의 기간이 오프라인 쇼핑몰에 비해 매우 짧게 나타난다. 즉 오프라인 쇼핑몰의 경우 구매 희망물건을 바로 구매하기 보다는 몇 개의 물건들을 모두 모아서 구매하는 행태가 일반적이다. 하지만, 인터넷 쇼핑몰의 경우 단 하나의 물품만을 포함하고 있는 주문이 전체 주문의 절반이상을 차지한다. 이러한 차이는 온라인 쇼핑몰 거래데이터의 분석을 위해서는 데이터 마이닝 분석에서 사용되어 온 장바구니의 정의에 대한 확장이 필요함을 의미한다. 하지만 현재까지 온라인 데이터를 대상으로 한 장바구니 분석 연구는, 장바구니의 기준 즉 동시구매의 기준에 대한 명확한 근거나 합의 없이 연구자의 선택에 따라 서로 다른 기준으로 수행되어왔다. 따라서 본 연구에서는 온라인 쇼핑몰 분석에 적용되는 동시에 구매되는 물건들에 대한 기준을 고찰해보고 연구모형을 마련하고자 한다.
