This study focuses on the problem of scheduling wafer lots of several recipe(operation condition) types in the photolithography workstation in a semiconductor wafer fabrication facility. and sequence-dependent recipe set up times may be required at the photolithography machines. In addition. a lot is able to be operated at a machine when the reticle(mask) corresponding to the recipe type is set up in the photolithography machine. We suggest various heuristic algorithms. in which developed machine selection rules and lot selection rules are used to generate reasonable schedules to minimizing the total weighted flowtime. Results of computational tests on randomly generated test problems show that the suggested algorithms outperform a scheduling method used in a real manufacturing system in terms of the total weighted flowtime of the wafer lots with ready times.

Small and medium companies have few dedicated employees for process planning and analyzing. They have many defects in their operational processes which result in less productivity. This research analyze a process of small company, which makes a hole and a round for gear parts. We found that the drilling operation is a bootle-neck operation and propose a revised general machine for drilling operation.
The legacy drilling operation is performed as follows. First, a operator drills a half hole of a part and turns the part upside down. Then he drills a rest hole of the part. The operation needs more efforts than other operations. Therefore a productivity of the factory depends on that of the drilling operation. We developed a horizontal multi-drilling machine for the drilling operation. The machine has the drilling tool heads and takes three parts and makes a hole at the same time. It eliminates human operation in the middle of drilling, We also developed clamping jig for holding parts tightly. The proposed machine reduces the total operation time and enhances the productivity of the factory. The process capability index also increased from 6.8 to 9.6.

The objective of this research is to introduce key performance indicators (KPIs) measuring overall equipment effectiveness (OEE) or overall operation effectiveness (OOE) effectively. OEE is one of the most effective KPI to measure the productivity and quality levels of an equipment-centric manufacturing company and widely implemented with a spreaded TPM (total productive maintenance). OEE is the most representative time-related KPI. For ease of measurement, OEE is calculated on the basis of the quantity of the processing materials and theoretical cycle time instead of using time-related sub-indicators. Hence, setting up theoretical cycle times is the most important aspect of the OEE measurement. Increasing customer's demand and developed manufacturing technology, more products can be made in a machine. So there will be multiple theoretical cycle times in a machine, but they have not been extensively considered for setting up theoretical cycle times in previous research. Futhermore the limitation to measure a performance of an operation which is consists of multiple machines is often mentioned in previous research. This paper shows how to measure OOE based on multiple theoretical cycle time.

열화현상은 공학시스템에 잦은 고장의 원인이 되며, 고장은 시스템이 가동되지 못하는 시간 동안의 기회비용을 증가시킨다. 보전 정책은 고장으로 발생하는 시스템 운영중지 상태를 개선하며, 이로 인한 기회비용을 줄이는 목적으로 실시한다. 일반적으로 보전 정책은 불완전 보전효과를 지니기 때문에 현실의 상황을 최대한 반영하는 보전 정책을 수립하기 위해서는 이를 고려해야 한다. 개선 요소(improvement factor) 방법은 불완전 보전 효과를 표현하는 방법 가운데 하나이며 대표적으로 나이 감소 요소와 위험률 증가 요소가 있다. 본 연구는 보전 정책의 불완전 보전 효과를 고려하는 방법으로 나이 감소 요소와 위험률 증가 요소를 결합한 하이브라드 요소(hybrid factor)를 사용한다. 보전 정책은 신뢰성 수준에 따라서 시행 사점이 결정될 수 있기 때문에 보전 시점을 결정하는 방법으로 특정 신뢰성 수준을 설정하고 이를 만족하는 예방보전 정책을 결정 한다. 즉, 본 연구에서는 하이브라드 요소를 이용하여 불완전 보전 효과를 최대한 반영하고, 특정 신뢰성 수준을 보장하는 예방보전 정책을 제시한다. 또한 기대 순수익 함수를 통해 최적의 예방보전 수를 결정하는 방법을 제시한다. 그리고 와이블 분포에 대한 수치 예제를 제시한다.

We want to accept or reject a finite population with reliability demonstration test. In this paper, we will describe Bayesian approaches for the reliability demonstration test based on the samples from a finite population. The Bayesian method is an approach that prior distribution and likelihood function combine to from posterior distribution. When we select somethings in a samples, we consider hypergeometric distribution. In this paper, we will explain the conjugacy of the beta-binomial distribution and hypergeometric distribution. The purpose of this paper is to make a decision between accept and reject in a finite population based on the conjugacy of the beta-binomial distribution.

우리나라의 보편적 장치산업의 각 생산공정 공정 세팅(setting)치는 Adjacent Point를 지향한다. 바로 이 점이 운전 세팅치를 자주 변경하게 하는 것이다. 다시 말해 근접한 점에 맞추려고 하는 행동이 군내 변동은 작게 만들지만, 군간 변동은 더욱 크게 만드는 현상을 초래하고 있다. 이 경우 데이터의 자기상관에도 나쁜 영향을 미친다고 할 수 있다. 또한 빈번히 사고성 Control-out도 나타나게 되며, 장기적으로 보았을 때 설비의 내구성에도 영향을 마치게 된다. 이는 4M 표준화의 필요성과 중요성이 강조되는 이유이기도 하다. 최근에는 다행스럽게 현장 작업자의 4M 표준화(세팅치 포함) 변화의 권한과 행위는 지양되고 담당 Engineer에게 절대적인 책임과 권한이 주어져 4M 표준화 및 공정의 Control-in 개념도 자연스럽게 재고되고 있는 상황이다.
ARIMA를 이용한 통계적 모형을 만들어 분석하는 것이 최고의 결과를 도출하기 위한 방법이라고 할 수 있으나, 이 방법은 모형을 만들고 분석하는 과정이 너무 어렵고 복잡하여 많은 데이터를 다루는 공정에서 사용하기에 무리가 있는 것이 사실이다. 다소 간편하다 할 수 있는 AR모형을 이용하여 관리 상한과 하한 폭을 넓혀서 분석하는 방법도 있지만, 이 또한 마찬가지로 과정이 어렵고 복잡하다.
실제공정에서는 자기상관이 소멸되는 시간간격 데이터를 이용한 Shewhart 관리도로도 공정 관리 상태를 판독하고 관리하는데 별 무리가 없다고 인지되는 상황이다. 그러나 Adjacent Point를 지향한 운전 습관은 그대로 남아 이상원인 검출에 어려움이 생길 수 있다.
본 연구에서는 기존의 Shewhart 관리도보다 가중치에 따라 작은 변화에 보다 더 민감하게 반응하는 EWMA 관리도를 바탕으로 장치 공정에서의 모니터링 효율성 재고를 위한 모델을 제안하고자 한다.

In the project management context, the impotance of risk management is increasing because the risks in terms of time and cost may significantly affect the result of the project. In general, the management of projects schedule risk is achieved by modeling project schedule with PERT/CPM techniques, then performing risk assesment with monte-carlo simulation method. However, these approach can not reflect constraints, which may be occurred during the project execution, and cope with uncertainty in the future. As these constraints may affect time and cost which are the crucial evaluation factor to the project, they must be identified and evaluated to manage the future project risk before the project is started.
This paper proposes a methodology for project schedule risk management by identifying and enforcing the constraints which may be occurred in complex and uncertain project environment. First, project risk constraints are identified and categorized into time, dependancy, and branching. Then, project schedule model with constraints is converted to CPN(Colored Petri Net) which can represent all the identified constraints to assess and predict schedule risk. Finally, the expected risk of the project (in terms of time and cost) is assessed and predicted by performing Petri Net simulation.
By using the methodology proposed in this paper, the risk in terms of time and cost in project schedule model can be assessed and predicted more accurately and practically than the PERT/CPM and/or Monte-carlo simulation method. Furthermore, the constraints, which may occur unexpectedly after the project launch, can be evaluated to determine the schedule risk. The expected risk can be used to decide whether risk mitigation or project termination process undertake.

The current number of mobile subscribers reached 50 million people can be seen as a nearly saturated state. To attract new customers means that coming to take away from the competition’s customers, so there are the fierce competition to attract to customers. So if there are signs of churn, it should be quickly analysed to avoid moving to competition. This paper estimated the churn of mobile users by using Competing risks model and Bayes’ theorem, and proposed how to prevent it. Proposed method was verified through the experiment, and it has been shown that the results of using the model is effectively predict the probability of churn of mobile users.

The appearance and evolution of SaaS over the recent years is potentially one of the major advances in information technology. However, if SaaS is to achieve its potential, there needs to be a clear identification and understanding of the various issues involved, both from the perspectives of the providers and the consumers of SaaS technology. While a lot of studies are currently taking place in the technology itself, there is an equally urgent need for understanding and researching the business-related issues surrounding SaaS service. As more and more individuals and companies use the SaaS service, their concerns are beginning to grow about just how safe and reliable an environment it is. For successful implementation of SaaS service, it is necessary to establish the certification systems to ensure safety and reliability of SaaS. This paper provides the safe and reliable framework for systematic SaaS certification systems. In order to develop it, the critical issues related to service quality and certification of SaaS service are identified and the systematic framework for certification systems of SaaS service and service provider domains are developed. A evaluation methodology for the developed certification systems is also proposed.

A packaging company is designing reusable multi-folding plastic box with RFID function. They want to identify material flow and inventory status of multi-folding box by adapting RFID technology and reallocate the boxes to required distribution centers. This reusable box may contain various types of materials such like liquids, metals, farm products and so on.
Recently, RFID technology has been widely applied in the industrial fields, especially in logistics. However, RFID technology has some problems. One of the problems is that it doesn't guarantee the RFID recognition with environment of metals and liquids. We cannot overlook this fact because the contents of box is not fixed and may contain various kinds of materials.
The purpose of this research is to analyze the influence of unspecified contents on the RFID detectability of reusable multi-folding box and predict the reading rate on various conditions. At first, we selected a list of test materials from expert interview and literature survey and performed experimental design to investigate influence by materials. Then, we built a prediction model using support vector machine (SVM) to predict reading rate on various conditions. The proposed model is based on intelligent machine learning algorithm. It gave a high accuracy of prediction, and provided robust combinations of conditions as to detectability on various contents. Finally, we performed sensitivity analysis about marginal detectability of influencing factors and found out tolerable level of factors.

This research has been studied a quality management method of silicon wafers for solar cells using the time series analysis. The model which can forecast conversion efficiency in state of a silicon wafer of a solar cell was presented newly and studied its limits. The first approach analyzed correlation between quality characteristics which was currently known and the quality of the last production. Also, The special factor which was unknown to a general factor until now was found. This paper presented the time series analytical model which was transformed in order to forecast exactly the influence that these special quality characteristics were immersed in to the conversion efficiency of cells. Using the correlation of forecasted value along the arbitrary change of measured value, the most optimized reduction factor for calculation of weight to be suitable for this model was defined.
