Many researches and projects are actively implemented in the academic world and industrial world in order to increase the productivity through changing utility layout. Effective layout makes the flow of parts and products go on wheels and helps labor forces and utilities to be used efficiently. In this study, we looked at effect on utility layout change through a case of a company making a fuel tank of vehicle in Korea. Due to the layout improvement, this company could have flowshop system on welding line, so the stock in line was decreased, checking the number of stock became easier than before and it was possible to evaluate exact cycle time per unit. Through not only confirming qualitative effect, but also checking quantitative effect such as UPH(Unit per Hour), we obtained the conclusion that the layout improvement increased the productivity.

Project implementation plan is a blueprint that confirms project performance activities and specifies required man-hour, period and resource imput ratio. Various figures, the results of implementation plan, are predicted through estimation, and because of superiority of objectivity and repeatability, numerical formula-based estimation model is often used overseas. COCOMO model is the representative estimation model whose theories and formulas are publicized and it predicts the total man-hour required for software system development. This model is publicized in "Software Engineering Economics" written by Professor Barry Boehm of the U.S., and is the most widely applied numerical formula-based estimation model. This study is conducted to provide a series of methods that are optimal for KTDS environment by choosing COCOMO II model among various types of COCOMO models. In establishing implementation plan, COCOMO II model alone is not sufficient, it is necessary to link with and apply standard WBS system and standard man-hour. In establishing specific implementation plan, phased standard WBS system in order of the first phase of all the activities implemented in the project, Activity, Task, and Role, and the man-hour put into this should be distributed according to standard ratio from COCOMO II model's total man-hour. This study provides explainations by establishing standard WBS system and linking with COCOMO II model.

The goal of this study is to analyze an effect of productivity elevation. For the goal, the various methods of the productivity elevation were suggested and the system improvements were conducted. The S company was established in Ban-Wol Industrial Complex, Ansan-City, Kyonggi-Do on 2007. The company was hiring 22 employees. The main manufactures were heavy duty equipment parts and the amount of sale was two billion won on 2008. Problems which the company faced were ambiguous production target management and materials loss. To solve the problems, NCT work improvement and automatic welding were induced. There were steel saving of 3,780,000won/month and man-hour saving of 144,000won/month by redesign of the steel sheet for the NCT steel job. Also, changing from handwork to automatic welding, the man-hour saving for the welding job was 320M/H and saving of 4,225,600won/month. The others of systematic improvement for productivity elevation were usage of jig and daily equipment checklist.

Service productivity is a brand new concept in the service industry, since it is quite different with conventional productivity. While the productivity in manufacturing is one of the quantitative measures for evaluating process efficiency, the service productivity include the nature of customer satisfaction as well as those of service process efficiency. Customer satisfaction, also called service quality in the service industry is one of the most difficult factors to measure quantitatively due to its intangibility. Hence it is also difficult to measure the service productivity correctly. It is hard to find the existed models for service productivity or related research papers in the literature. In this study, a new model which can be used to measure and evaluate the service productivity considering both the service quality and the productivity of service process is proposed. AHP, one of the well-known multiple-criteria decision-making methods, is applied to deal with both quantitative and qualitative factors in the model. The methodology and the procedures for measuring and evaluating service productivity are also presented.

This paper proposes a standard open source software development guidance and an evaluation index for the productivity related to Seam 2.0 and Spring 2.5 framework. However, there is no comparison research about the performance of Seam 2.0 and Spring 2.5 framework with same identical platform. Quantitative analysis is supported as a part of LoC analysis. There is a limit to develop the updated software with no the specific evaluating index for the productivity of the software. This work proposes an specific index for evaluating the productivity of Seam 2.0 and Spring 2.5 framework on a platform. Base on the result, the specific guidance of the developing software is obtained.

Competitive capacities in terms of price are rapidly deteriorating since the 1990's due to the competition and rapid pursuit of surrounding nations, exchange rates, increased wages, and labor and management disputes etc. Therefore, this paper shows the significant contents of preceeding research, surveys the employees of small and medium manufacturers who implemented the Toyota production system to conduct various analyses to determine the effect of the operation achievements so as to propose methods to effectively implement the Toyota manufacturing system and maximize long term operational achievements.

Today's fierce competition and global economic recession make most of manufacturing companies in the world difficult to gain a profit. In order to survive such a environment and increase competitiveness, manufacturing companies have to continuously eliminate their wasteful factors through an efficient process analysis, improve quality of products, increase the flexibility of manufacturing processes. In this paper, we consider a case study for the Shanghai New Auto which is a subcontractor of MOBIS in China, to improve productivity by using therblig method, one of the motion analysis, to minimize the work-in-process inventories and to shorten the manufacturing cycle times. We also try to relocate the facility layout to increase the efficiency and flexibility of manufacturing processes.

재식거리 3.2×1.2m로 심어 수고 2.5m의 세장방추형으로 관리해 오던 '후지'/M.9 사과나무를 재식 6년차부터 2년 동안 수고 4.0m로 관리하였다. 이후 재식 8년차에 수고를 2.5m(대조구), 3.0m, 3.5m, 4.0m로 조절하고 수고에 따른 2년간의 생산성 및 노동력을 비교하였다. 대조구인 수고 2.5m를 기준으로 하여 처리에 따른 10a당 생산량을 비교해 보면 첫해에는 수고 4.0m, 3.5m, 3.0m에서 각각 46%, 25%, 4%, 2년차에는 17%, 12%, 10% 증가하였다. 수고에 따른 과실 품질에 있어서는 가용성 고형물 함량은 2개년 모두 수고 2.5m가 가장 높았으나, 착색정도는 수고에 따른 뚜렷한 차이가 없었다. 노동력은 수고가 높아질수록 증가하였으나, 노동력에 따른 과실생산량은 수고가 낮을수록 증가하였다. 조수입과 순수입은 2005년의 경우 수고가 높아질수록 증가하였으나, 2006년은 수고 2.5m가 가장 높았지만 통계적 유의차는 없었다. 따라서 수고에 따른 생산성, 노동력, 경제성을 고려해 볼때 적정수고는 3.0~3.5m인 것으로 판단되었다.
