Productivity analysis is the most important and significant method for evaluating management and engineering performance during whole project stage. However, it is very difficult in developing qualitative index to construction industry comparing to other industries. Therefore, analytical hierarchy process (AHP) is one of the methods for overcoming these limitations by checking consistency index using duality comparison. In this study, it is scraped up an application plan and selection for innovative tools by analyzing survey results on tool users and site managers with respect to using Modified-AHP performance measurement method.

This study provides the method how to improve the productivity of a project using CM's constitutive methods. Construction industry in Korea was protected by the government and they have been grown with only their construction technology until today. It results Korean Construction is behind the advanced countries in terms of Engineering fields and construction management skills. This study compares the difference between the construction system of Korea and Europe and Asia. And then, it proposes the method how to compete with the other countries. which introduce the CM technique into the construction project in the beginning stage. Hopefully, this study is recognised as the basic strategy to improve the capability of Korean construction management.

Productivity is the essential comparative advantage in high tech industry company in 21 century. These company endless endeavor for low cost production. Low cost production can be led by low facility operation cost and low labor cost. But reducing facility operation cost arise much investment. Thus many high tech company drive reduction of labor cost. These article suggest model for reducing labor cost and prove a effect by example of some company.

In the construction industry, construction management system using information technology has been applied diversely to increase productivity. Although IT device such as PDA, RFID, Barcode, wireless network and web camera has been introduced in construction site, the usage of these device is restricted, because these cause engineer to do additional work. The suggested process using Digital Pen in this study, which can lessen engineer's additional work, get defect data promptly. Also accumulated data is utilized effectively for analyzing construction site. The purpose of this study is to introduce Digital Pen System as a means of construction data acquisition for improving productivity.

Over the past several decades, several architectural approaches have been applied to develop Information Systems, The software architectural model has been recognized as one of the most important methods for improving productivity. Most conceptual models are difficult to understand and interpret at various system models. As a consequence, conceptual models of many Information Systems fail to represent, exploit, and apply to various aspects, which is needed for reducing development step of the architecture. In this paper, we will explain the architectural model as the 4＋1 View of UML. This model integrates the Knowledge Management System into five views： the Logical View, the Process View, the Deployment View, Implementation View, and the Use-Case View. Moreover, this paper will not only provide information on the application of the software architectural model by stakeholders, but also ultimately improve productivity.

In the recent, it is gradually important for airport to consider environmental aspects as sustainable development is emerged. ICAO, FAA and individual countries has tried to reduce airport noise and pollution. Thus, the effort is needed to incorporate environmental factor into productivity indicator of airport. Our paper use DEA method with the non-parametric directional output distance function(DDF) to assess productivity of 14 airports in Korea during 2008~2010. In addition to three inputs, two conventional outputs, two undesirable outputs have been considered : noise and air pollution. Results are compared from models that do not include undesirable outputs. Inclusion in the analysis of the undesirable effects of airport operations leads to greater and closer airport's efficiency scores.

This paper describes computer-integrated manufacturing (CIM) systems as strategic information systems for business which play an important role in accelerating the speed of business, and develops a measure showing a degree of business tendency to be CIM which enables the business to check on its present status as far as CIM is concerned. It is well known that the productivity of knowledge workers is lower than that of other workers. Nowadays, a great deal of effort goes into the productivity improvement of knowledge workers. In this respect, this paper also develops a quantitative model for the productivity of knowledge workers. Finally, this paper deals with following four steps which our small business should follow through its process of CIM: [Step 1] Using expert knowledge; [Step 2] Invention of technological information; [Step 3] Feedback of factory information to the management; and, [Step 4] Accelerating the speed of business.

Investments in factory automation do not guarantee productivity enhancement. Much unknown losses may exist in all aspects of production resources such as in material, manpower, machine, etc. Total productivity in korean firms has decreased in recent years. Labor and capital productivity index fall to 0.82 point and 0.73 point, respectively. Investment in FA has Increased rapidly. Tangible fixed assets per capita increased 64% during the past Three years. But, this high-technology oriented systems such as NC, robotics, CAD/CAM, FMS, etc. are often out of keeping with the old production process control, and thus do not result in satisfactory performance. This review paper concerned with these problems and suggests some future directions for production control and development strategy of korean firm's.

It is an important issue in cost management to contract with the standard of cost estimate by the reasonable way in public construction projects. For the standard of cost estimate based on the Standard Estimating System, there is a difference of labor inputs between Standard Estimating System and actual quantities in construction projects. The duration of form work in multi-family housing depends on the manpower compared with other work, which is the critical path on the schedule management to be decided quality, and is the important to the cost management of construction projects. This study presented a simulation model of the productivity analysis for selecting the standard work type of form work in Multi-family housing construction projects.

본고는 생산현장에서의 인적자본 축적, 즉 근로자의 숙련형성에 영향을 주는 요인들을 실증적으로 찾아보고, 형성된 숙련이 생산성 향상에 기여하고 있는 것을 확인한다. 먼저 숙련형성의 유형은 '단순/견습근로자 < 단능근로자 < 다능근로자'의 직렬적 순서이다. 제품수요의 급변성과 비정상적인 상황 발생이라는 외부적 내부적 불확실성이 클수록 다능화가 활발하게 이루어지고 있으며, 선배 동료 근로자와의 상호학습, 근로자의 의사결정 참여, 직무 순환 등의 인적자원관리 관행들도 다능화를 촉진한다. 이러한 발견들로부터 생산 현장에서의 숙련형성은 다능화로 대표될 수 있다고 판단된다. 기업의 노동생산성 성장률을 기업의 성장률이라고 하면, 불확실성과 인적자원관리 관행들은 다능화를 통해서 기업의 성장에 영향을 준다. 구체적으로 기업의 다능화 비율이 0.1만큼 올라감에 따라 노동생산성 성장률이 0.019만큼 증가한다. 이것은 또한 다능화가 인적자원관리 관행들에 영향을 받아 형성되는 인적자본 축적의 한 결과라는 주장에 대한 근거가 될 수 있다.
