  • 본 논문은 품절기간 중 수요의 일부는 부재고되고 나머지 일부는 유실되는 재고 모형을 제시한다. 부재고되는 수요량은 불확실하다. 따라서 부재고되는 수요의 양을 확률변수로 놓고, 부재고되는 수요량의 표준편차가 누적품절량의 크기에 비례하는 경우를 다루었다. 투영에 의한 분해법(decomposition by projection)을 사용하여 최적 재고 정책을 도출하였다.

  • Distribution System is considered as the most important part of SCM when the satisfaction of customer demand is considered. This paper focus on the backorder policies for stockout which is occurred in each regional distribution center of two-echelon distribution system facing stochastic demand process. Four concepts for the efficient system operation are suggested. First, at least 30% reduction of stockout is achieved by introduction of 50/25 allocation policy to distribution system. Second, transportation cost and lead-time of backorder are decreased by allowance of internal supply between regional distribution centers. Third, the frequency of emergency supply is minimized by application of Ship-up-to- expected-demand backorder policies. Finally we suggest several effective rules to select multi-internal suppliers. Simulation tests show the efficiency of our backorder policies and enhancement of customer service level.

It is meaningful that our school libraries, which have been alienated due to the lack of government polices, are not following in the footsteps of the past, as they are in need of state support.

  • 국내 양돈업계는 축산물 수급정책의 부재와 가격안정제도의 불균형으로 주기적으로 닥쳐오는 가격폭락 영향과 축산물 수입개방, 축산분뇨 처리의 애로,인력난 등르로'88~'89 2년간 축산농가중2/3가 도산하므로서 생산기반이 무너져 가고 있는 현상을 대변하고 있다. 따라서 정부는 정업농 보호정책과 계열화사업 지원 시설자동화에 장기처리로 과감히 투.융자를 하는 한편,축산분뇨의 자원화와 재활용에 정책적배려를 해야 하겠다

  • This study aims to examine the level of precariousness among young adults in South Korea and analyze the factors affecting their subjective well-being by adopting the three forms of precariousness suggested by Rodgers(1989) such as lack of resource, uncertainty and disempowerment as its analytical framework. Structural Equation Model was used for analyzing the path model of self-rated health, income level and social support(three forms of resource) affecting subjective wellbeing through uncertainty and disempowerment. Study population include young adults aged between 19 to 34 with a sample size of 415 using data of the 8th wave of the Korean General Social Survey(KGSS), 2010. Study population is divided into lower-age group (aged between 19-26) and upper-age group (aged between 27-34) in order to examine the differences between age groups by using Multiple Group Analysis. Study results show that three forms of resources, uncertainty and disempowerment had direct effect on the subjective well-being of South Korean young adults and disempowerment had the most significant effect among the factors. In addition, self-rated health and income level had indirect effect on subjective well-being through both uncertainty and disempowerment while social support had indirect effect on subjective well-being only through disempowerment. Results from the Multiple Group Analysis indicate that among the two age groups, income level only has a significant effect on subjective well-being in the upper-age group. In addition, disempowerment had greater effect on subjective wellbeing among upper-age group than the lower-age group. Based on the study results, this paper suggested policy implications and discussion for further research.
