In supply chain management, coordination between a manufacture and suppliers Is regarded as the most important issue when partnership of organizations of considered. This paper Introduces the current status of SCM in terms of physical systems, relation with other solution systems as well as the general history and definitions of SCM. Researches are categorized into deterministic, stochastic, and several future research areas are discussed in the paper.

By successful establishment of SCM(Supply Chain Management) System they should make the supply chains speedy and combine production information system with the outcome system and thus they reinforce the competition of the production system of local enterprises in accordance with the rapid decision making This study is to develop the most appropriate production system models through the reflection of JIT system in the SCM which is the necessity of the times and its importance. To achieve this goal the researcher diversifies the prerequisites for the success of the business which will be the strategical factors of the production systems. The objects of this study is to develop the most appropriate production system models and to provide the enterprises with the models which are based on the SCM.

In the supply chain, The ATP function doesn't only give customers to confirmation of delivery. It can be used by the core function with ATP rule that can reconcile supplies and demands on the supply chain. Therefore We can acquire the conformation about accuracy on the due date of supplier by using the ATP function of management about real and concurrent access on the supply chain, also can decide the affect about product availability due to forecasting or customer's orders through the ATP. This study analyze the data concerned with ATP and define the necessity on a SCM solution. Under the these environments, after defining the ATP rule that can improve the customer value and data flow related the CRM, we propose the advanced ATP model that proposes the method and classification system that can flexibly aggregate the ATP data with ATP rule on the supply chain.

Today's environment of enterprise is changing. They have to face customers' demands with the right product, the right service and supply them at the right time. And aIso cut down logistics and inventory cost and bring up the Profit as much as they can. This means the change of putting enterprise first in importance to putting customer first in importance. therefore to correspond to customer's demand, shorting lead time is becoming a essential condition. The answer to this changes of environment is supply chain management In this study, we use Goldratt's drum-buffer-rope scheduling in between manufacturer and supplier. And when shortage of inventory occur, search for the supply chain's CCR. Pressing CCR for more production, and supply Inventory from logistic center to guide for inventory buffing. using logistic warehouse between manufacturer and supplier, can execute function of buffer.

오늘날 기업환경은 고객의 요구에 대응하여 적시에 효율적으로 상품과 서비스를 공급하고 전체비용의 대부분을 차지하는 물류와 재고비용을 줄여 기업의 이윤을 극대화하는 것으로 변화하고 있다. 예전에 기업위주의 시장형성에서 고객위주로 시장이 변화하고 있는 것이다. 이에 따라 기업은 고객의 요구에 능동적으로 대응하기 위하여 리드타임의 단축이 필수적인 요소가 되어가고 있다. 이러한 기업환경에 변화에 따른 대안으로 나온 것이 실시간 제조와 공급사슬망관리(Supply Chain Management : SCM)이다. 본 연구는 실시간 제조를 지원하기 위하여 제조업체와 협력사간의 물류에 있어 Goldratt의 Drunm-Buffer-Rope 스케줄링을 이용하여 물류창고라는 Buffer를 두어 협력사중 재고의 부족현상이 일어날 경우에는 공급체인상의 능력제약자원(Capacity Constraint Resource: CCR)을 찾아 능력제약자원이 되는 협력사에 대하여 생산을 독촉하고 물류창고에서는 부족재고에 대한 불출을 개시하여 재고의 완충을 도모하고자 한다. 제조업체와 협력사간의 정보를 실시간 감시시스템(Real-Time Monitoring System : RTMS)를 응용하여 웹상에서 공유하며, 실시간 거래가 가능토록하는 공급사슬망 구축에 관한 연구와 이를 프로그램 구현을 통해 실제적으로 시험해 보고자 한다.

공급망상에서 ATP는 단순히 고객에게 납기를 확약해 주는 고객 서비스 기능이 아니다. 이것은 공급 망상에서 ATP Rule을 기반으로 하여 수요와 공급 일치에 도달하기 위한 핵심 기능이다 따라서 SCM Solution을 이용하여 공급 체인 전반에 걸쳐 제품 가용성에 대한 즉시 및 동시 엑세스를 관리하여 기업의 납기 일의 정확도에 대한 최고의 확신을 가져올 수 있으며, SCM Solution을 통해 주문이나 예측 수주로 인하여 새로운 수요가 제품 가용성에 미칠 영향을 결정할 수 있다. 본 논문에서는 공급체인 전체의 통합관리 솔루션을 통하여 SCM에 대한 필요성을 정리하고 ATP관련 데이터를 분석을 수행한다. 이 것을 바탕으로 고객관계 관리( Customer Relationship Management)와 연계하여 세부데이터의 흐름 및 고객 가치를 향상 할 수 있는 ATP Rule을 정의한 후, 본 논문에서는 공급망상에 ATP Rule을 적용하여 ATP관련 데이터를 유연성 있게 취합할 수 있는 방안과 분류체계를 제시한 다단계 ATP모형을 제시 한다.

SCM은 원자재를 공급받아 이를 완제품으로 만들고, 최종소비자에게 판매하는 일련의 사업단위를 관리하는 기법이다 즉, 주문창출, 주문접수, 주문이행 그리고 상품, 서비스 및 정보의 유통, 협력을 포함한 총괄적인 개념의 용어이다. 또한 원자재의 공급자에서부터 최종소비자까지 연결하는 생산의 흐름을 최적으로 운영하고 조율하는 것이 SCM의 목적이다. Supply Chain상에는 여러 개의 다른 조직체와 활동에 필요한 많은 기능(설계, 생산, 조달, 운송 등)이 존재하며, 전체 Supply Chain의 효율성을 증가시키기 위하여 실물, 정보, 자금을 최적으로 관리하는 것이 SCM의 역할이다. 본 논문에서는 이러한 SCM의 근간이 되고 있는 EDI의 조달시스템에 초점을 맞추어 가상 시나리오를 세우고, 업무를 분석하여, 데이터베이스를 설계하고, 마지막으로 웹상에서의 페이지들을 개발하고 이들을 연결하여서 최종적인 시스템을 구현하였다.

현재 자동차용 소재 및 기계부품에 폭넓게 이용되는 SCM415강의 플라즈마 침탄 특성을 연구하기 위해 가스조성, 압력, 전류밀도, 온도 및 시간을 변수로 사용하였다. 가스조성의 경우 저합금강에서는 수소 가스 효과보다 메탄가스에 의해 주로 침탄특성이 좌우되며 메탄가스 100%일 때 시편 내의 모든 방향에서 경화층 분포가 일정하고, 최대의 유효경화깊이를 얻을 수 있었다. 가스압력이나 플라즈마 전압이 상승할 때 전류밀도가 상승하게 되는데, 이에 따라 최표면의 탄소농도가 증가되어 강의 유효경화깊이는 증대되었다. 침탄 온도일 경우 적어도 850˚C이상되어야 유효경화깊이를 얻을 수 있었고, 온도가 상승할수록 유효경화깊이의 증가를 나타내어 침탄 효과가 우수하였다. 탄소의 확산 깊이는 침탄 시간의 제곱근에 비례하는 것으로 나타났다. 플라즈마 치탄한 강의 피로강도를 평가한 결과 열처리하지 않은 시편이나 재가열처리한 시편에 비해 높은 피로강도를 나타내었다.

여러 온도에서 급냉 및 템퍼링시킨 SCM440강을 이용하여 결정입도와 조직의 변화가 초음파감쇄에 미치는 영향에 관하여 연구하였다. 초음파감쇄는 주로 결정립에 의한 산란에 기인하였으며 감쇄계수는 결정립의 크기가 클수록 증가하였으나 템퍼링 시킨 조직의 경우 템퍼링온도가 높아질수록 감쇄계수는 감소하는 것을 알 수 있었다. 주파수의 의존성은 직선적인 log-log 관계를 가지며 Roney의 식과 비례하는 것으로 조사되었다.

초음파의 표면파의 전파특성을 이용하여 SCM440강의 고주파열처리의 정도에 따른 표면경화층의 깊이를 측정, 조사하였으며 침탄속도는 동일조직에서는 주파수에 관계없이 일정하였으나, 경화조직에서 경화되지 않은 조직에 비하여 표면파의 속도는 59m/s 늦었다. 강의 유효경화층깊이(d)와 표면파파장(λR)의 d/λR의 관계로부터 경화층의 ?이를 비파괴적으로 평가, 측정할 수 있었으며 침탄경화시킨 경우에서도 동일한 결과를 얻었다.

This study explored the impact of interactional justice on supply-chain collaboration and sustainable supply-chain performance. Accordingly, it classified interactional justice of supply-chain management (SCM) into interpersonal and informational justice, and empirically classified the effects of these subordinate concepts on supply-chain collaboration and sustainable supply-chain performance. To this end, 700 questionnaires were distributed, and 201 final valid responses were used for the statistical analysis which revealed the significant positive influence of interpersonal justice on informational justice. This indicates that courtesy, respect, and proper words are important in the relationship between buyers and sellers. Both interpersonal and informational justice had a significant positive relationship with supply-chain collaboration. The results suggest that a fair-trade environment should be cultivated to encourage and facilitate seller-buyer collaboration. Lastly, supply-chain collaboration had a positive influence on sustainable supply-chain performance. This implies that if justice is not perceived in the seller-buyer relationship, collaboration can be hindered, which negatively impacts corporate performance. These findings also helped to understand the importance of interactional justice and to propose a new relationship between interpersonal and informational justice.

Purpose : With the proliferation of O2O platform services that combine offline and online services, many startups are fiercely competing to lead services in the O2O service market. While the prospects for growth in the O2O service market are optimistic because of the close convenience to life, startups can achieve corporate performance only through close cooperation and partnership with suppliers. The purpose of this study is to verify the effect of O2O-based startups' and suppliers' cooperation in supply chain management on SCM performance through supply chain partnerships and startup satisfaction with suppliers. Research design, data, methodology : Data were collected from O2O service-based startups and hypotheses were verified through frequency analysis, exploratory factor analysis, reliability analysis, confirmatory factor analysis, feasibility analysis, and structural equation path analysis. In addition, the mediating effects of supply chain partnerships and startup satisfaction on suppliers were verified. Results : As a result of this study, IT utilization of the O2O startup cooperation method affects the financial perspective of supply chain partnership and SCM performance. The contract implementation of the cooperation method had an impact on the financial and innovation growth perspectives of the SCM performance, and the communication of the cooperation method had an effect on the supply chain partnership, startup satisfaction in the supply chain, and the innovation growth perspective of the SCM performance. Supply chain partnerships had an impact on the financial, innovation growth, and customer perspectives of SCM performance and startup satisfaction within the supply chain had a significant effect on innovation growth and customer perspectives. Conclusions : The implications of this study identified the factors that can improve SCM performance through the cooperation method of O2O startup, supply chain partnership and startup satisfaction with suppliers, and it is significant that the causal relationship was identified by the structural model through the supply chain cooperation factors derived by characteristics. Based on the empirical results, as the services of O2O startups grow, it is expected that empirical research and practical activation of academia should be considered as important in the cooperation of the supply chain

From the previous research, as a solution of carbonation of high-volume SCM concrete, outstanding performance of emulsified refined cooking oil with applying on the surface of the concrete was suggested. As a comparative study, the aim of this research is evaluating carbonation resistance and pore structure of high-volume SCM concrete depending on the painting substances of emulsified refined cooking oil and modified silicate base permeating paint, which is commercial product by mock-up test.

The aim of the paper is to solve the problem of customer reduction due to the difficulty of parts sourcing which impacts production delay and delivery delay in SC networks. Furthermore, this paper is to suggest the new inventory policy of MTS in order to solve the problem of current inventory policy. In order to compare two policies, a LCD maker is selected as a case study and the real data for 2007 years is used for simulation input. The maker uses MTO policy for parts sourcing which has the problem of lead time even if it has some advantage of inventory cost. Based on current process. The simulation program of AS-IS model and TO-BE model using ARENA 10 version is developed for evaluation. In a result, the order number of two policies shows that MTO is 52 and MTS is 53. However the quantity of order shows big difference such that MTO is 168,460 and MTS is 225,106. Particularly, the lead time of new inventory policy shows much shorter that that of MTO such that MTO 100 is days and MTS is 16 days. In spite of short lead time by MTS policy, new policy has to take burden of inventory cost per year. Total inventory cost per year by MTS policy is US 11,254 and each part inventory cost is that POL is US 1,807, LDI is US 2,166 and Panel is US 7,281. The implication of the research is that the company has to consider the cost and the service simultaneously in deciding the inventory policy. In the paper, even if the optimal point of deciding is put into tactical area, the ground of decision is suggested in order to improve the problem in SC networks.

Although renewable power is regarded a way to active response to climate change, the stability of whole power system could be a serious problem in the future due to its uncertainties such as indispatchableness and intermittency. From this perspective, the peak time impact of stochastic wind power generation is estimated using simulation method up to year 2030 based on the 3rd master plan for the promotion of new and renewable energy on peak time. Result shows that the highest probability of wind power impact on peak time power supply could be up to 4.41% in 2030. The impact of wind power generation on overall power mix is also analyzed up to 2030 using SCM model. The impact seems smaller than expectation, however, the estimated investment cost to make up such lack of power generation in terms of LNG power generation facilities is shown to be a significant burden to existing power companies.
