When we try to design a production planning system for a manufacturing company, it is a time consuming task to analyze various planning activities and identify inter-relationship among a lot of decisions made for the production planning. Most of the research efforts have been concentrated to well-organized independent decision-making problems that may usually be identified only after analyzing the characteristics of the decision-making process as a whole. In this paper, a methodology is suggested to characterize the whole process of the production planning for a manufacturing company and reduce the complexity of decision-making problems. The methodology is based on an experience of developing a production planning software for an automobile component manufacturer in korea. First, it is explained how to identify and represent the dependency among various decision-making variables. And a methodology is proposed to analyze the identified dependency among decision variables and identify decision-making process. Lastly, a practical example is provided to illustrate the analysis procedure in this paper.

The mathematical thinking which transforms important mathematical content and developed into mathematical structure is a vital process in building up mathematical ability as mathematical knowledge based on structure. Such process based on students' recognition of mathematical concept. Developing mathematical thinking into mathematical structure happens when different cognitive units are connected and compressed to form schema of solution, which could happen through some guided problems. The effort of arithmetic approach in problem solving did not necessarily provide students the structure schema of solution. The using of equation to solve the problem is based on the schema of building equation, and is not necessary recognizing the structure of the solution, as the recognition of structure may be lost in the process of simplification of algebraic expressions, leaving only the final numeric answer of the problem.

Limiting thermal exposure time using rapid thermal processing(RTP) has emerged as promising simplified process for manufacturing of solar cell in a continuous way. This paper reports the simplification of co-firing using RTP. Actual temperature profile for co-firing after screen printing is a key issue for high-quality metal-semiconductor contact. The plateau time during the firing process were varied at $450^{\circ}C$ for 10~16 sec. Glass frit in Ag paste etch anti-reflection layer with plateau time. Glass frit in Ag paste is important for the Ag/Si contact formation and performances of crystalline Si solar cell. We achieved 17.14% efficiency with optimum conditions.

This paper suggests an environmental improvement scheme for the enactment and revision process of the standard of construction estimation in communication field. The first subject is a simplification of process on the enactment and revision. It can be achieved by transfer the function to the professional board from the subordinate council. The second process is an adoption of tentative step on enactment and revision. And the last subject is creation of maintenance part. All the improvement shall be carried on in long term schedule and on the sufficient financial support from government.

Most power plants have operated many independent computerize systems for maintenance. Independence of systems have caused complexity of business process and inconvenience of computer system management. Because the equipment and material master data is not standardize and structurize, it is difficult to manage equipment maintenance history and material delivery. Especially equipment classification criterion is important for standardization of every maintenance information. It is necessary to integrate function of independent systems for business process simplification and rapid work flow. this paper provides equipment classification criterion design and system integration method with the case of live system development.

Inkjet printing is a typical printing technology with many advantages, such as material cost reduction, noncontact pattern formation without a mask, and process simplification. With the recent and rapid development of ink materials, parts and equipment, and process technologies related to inkjet printing, it is becoming a major process in various areas of the display industry. In particular, for the QD-OLED (quantum dot-organic light-emitting diode) display announced by Samsung Display in 2022, quantum dot pixel production by applying inkjet printing is a key technology. We analyze inkjet printing technology for mass production applied to the display industry and discuss the technology development trends in academia and industry toward the realization of next-generation displays.

In this study, the rise throughput and the stability in fabrication of device can be obtained by applying of CMP process to STI structure in 0.18um semiconductor device. To employ in STI CMP, the reverse moat process has been added thus the process became complex and the defects were seriously increased. Removal rates of each thin films in STI CMP was not equal hence the devices must to be effected, that is, the damage was occured in the device dimension in the case of excessive CMP process and the nitride film was remained on the device dimension in the case of insufficient CMP process than these defects affect the device characteristics. To resolve these problems, the development of slurry for CMP with high removal rate and high selectivity between each thin films was studied then it can be prevent the reasons of many defects by reasons of many defects by simplification of process that directly apply CMP process to STI structure without the reverse moat pattern process.

이 논문은 스프레드시트를 활용한 수학적 모델링에서 스프레드시트 환경이 수학적 모델의 정교화과정에 어떤 영향을 미치는 지를 고찰한 것이다. 좀 더 자세히 살피면 수학적 모델링에서 스프레드시트 모델의 활용은 학생이 분석 불가능한 수학적모델도 분석할 수 있도록 해줌으로써 모델을 단순화하지 않고, 대신 모델을 정교화 할 수 있는 기회를 제공하고 수학적 개념을 확장해 나갈 수 있음을 보였다. 또한 수학적 모델을 스프레드시트 모델로 변환하여, 수학적 모델로부터 수학적 결론을 얻는 단계를 거치지 않고도 실세계 상황을 해석하고 설명할 수 있는 기회를 제공할 수 있음을 보였다.

건설프로젝트에서 현재 사용되고 있는 작업분류체계(Work Breakdown Structure)는 프로세스 내의 세부작업간 선·후행 관계의 불확실성과 작업의 불합리한 상호 연계성에 기인한 문제점을 내포하고 있다. 이를 해결하기 위해서 본 논문에서는 Work Structuring을 제시하여 프로세스간에 투명성을 부여하고 세부작업간의 간섭을 제거시켜 작업신뢰성을 향상할 수 있는 방안을 도출하였고 프로세스를 개선하기 위한 프로세스 디자인 다이어그램을 개발하였다. WS에 의한 프로세스 개선의 목적은 고객에게 가치를 창출시켜주면서 보다 신속하고 신뢰성 있는 작업 흐름을 만드는 것을 목적으로 하고 있으며 비가치 창출작업의 감소, 프로세스의 명료화 및 투명성 향상 등에 의의가 있다.
