This study analyzes the distributor's inventory model in a two-stage supply chain consisting of the supplier, the distributor and the end customer. The supplier will allow a credit period before the distributor settles the account with him in order to stimulate the demand for the product he produces. It is also assumed that the distributor pays the shipping cost for the order and hence, the distributor's ordering cost consists of a fixed ordering cost and the shipping cost that depend on the order quantity. The availability of the delay in payments from the supplier enables discount of the distributor's selling price from a wider range of the price option in anticipation of increased customer's demand. As a result, the availability of a credit transaction leads to an increase in inventory levels. On the other hand, in the case of deteriorating products in which the utility of the product perish over time, the deterioration rate with time plays a role in reducing inventory levels. In this regard, we analyze the effect of the length of the credit period and the degree of product deterioration on the distributor's inventory level. For the analysis, we formulate the distributor's annual net profit and analyze the effect of the length of credit period and deterioration rate of the product on inventory policy numerically.

Background: A need arises to efficiently control health expenditure for medical aid due to a sharp increase in medical aid expenditure. This study experimently analyzes the impact of physician behavior on medical use for medical aid beneficiaries using supplier induced demand (SID) theory. Methods: This study looks into analyze SID effect using expenditure factor analysis of medical aid for the years between 2003 and 2010 in comparison with health insurance. Moreover, this study analyzes the existence and scale of SID using econometrics modeling with panel data on 16 cities and provinces's health expenditure data for medical aid from 2003 1/4 to 2010 4/4. Results: This study finds that the growth rate of visit days per capita and treatment amount per visit days for medical aid is higher than health insurance. Furthermore, the result of econometrics modeling analysis shows the existence of SID in general hospital, hospital, clinic, oriental clinic. Conclusion: In order to efficiently control expenditure for medical aid, it is required to reinforce macro polices such as the introduction of 'target management' and micro policies such as the strengthen of management on medical institutes in the perspective of suppliers as well as regulations of demanders.

Rapid knowledge change, heightened competition. and shortened product life cycles are just a few of the constants faced by many buying firms in today's markets. Many buying firms have responded to these conditions by outsourcing non-core activities. The Quality and cost of a product or service offered in the market is a function, not only of the capabilities of the firm, but also of the network of suppliers who provide inputs to the firm. When a firm finds its suppliers lacking in performance it can help suppliers to develop their capabilities. There are three main goals for this study. The first goal is to identify the important factors that precede and influence firms' investment in knowledge transfer activities. The second goal is to investigate the relationship between knowledge transfer activities and the consequences of knowledge transfer activities. The last goal is to explore the effects of knowledge change speed. To analyze the validity of the research model and the hypotheses. the data are collected from 238 manufacturing firms through the administration of structured Questionnaires. The results of structural equation model analyses indicate that the model is generally valid and 11 of 14 hypotheses are supported by the data. Reasons for and implications of these observed relationships are discussed.

공급 망 관리의 주요 이슈중의 하나는 재고부족(Shortage)이 허용되고 벤더가 공급자와 구매자 모두의 재고관리를 책임지는 상황 하에서, 재고수준을 결정하는 것이다. 본 연구에서는 두 개의 벤더재고관리 (Vendor managed inventory, 이하 VMI) 모델을 계시하고 각각의 해법을 개발한다. 두 모델 중 하나는 단일 구매자 및 단일 공급자 문제이고, 다른 하나는 두 구매자 및 단일 공급자 문제이다. 본 연구가 제안하는 방법론은 VMI모델이 전통적인 모델과 비교해서 어떠한 상황에서 적은 비용으로 운영될 수 있는지 결정하는 조건들을 유도해 낸다. 또한 수치예제를 통해서 제안된 방법론들의 타당성을 입증해 보인다.

This research paper introduces the application and implementation of medical decision metrics that classifies medical decision-making into four different metrics using statistical diagnostic tools, such as confusion matrix, normal distribution, Bayesian prediction and Receiver Operating Curve(ROC). In this study, the metrics are developed based on cross-section study, cohort study and case-control study done by systematic literature review and reformulated the structure of type I error, type II error, confidence level and power of detection. The study proposed implementation strategies for 10 quality improvement activities via 14 medical decision metrics which consider specificity and sensitivity in terms of ${\alpha}$ and ${\beta}$. Examples of ROC implication are depicted in this paper with a useful guidelines to implement a continuous quality improvement, not only in a variable acceptance sampling in Quality Control(QC) but also in a supplier grading score chart in Supplier Chain Management(SCM) quality. This research paper is the first to apply and implement medical decision-making tools as quality improvement activities. These proposed models will help quality practitioners to enhance the process and product quality level.

In this paper, we analyze a logistic system involving a supplier who produces and delivers multiple types of items and a buyer who receives and sells the products to end customers. The buyer controls the inventory level by replenishing each product item up to a given order-up-to-level to cope with stochastic demand of end customers. In response to the buyer's order, the supplier produces or outsources the ordered item and delivers them at the start of each period. For the system described above, a mathematical model for a single type of item was developed from the buyer's perspective. Based on the model, an efficient method to find the cycle length and safety factor which correspond to a local minimum solution is proposed. This single product model was extended to cover a multiple item situation. From the model, algorithms to decide the base cycle length and order interval of each item were proposed. The results of the computational experiment show that the algorithms were able to determine the global optimum solution for all tested cases within a reasonable amount of time.
