Indicies of the labor productivity were assessed from 80 industry foodservice erstablishments in terms of meals served per labor hour, labor minutes per meal served, and labor cost per meal served. The labor productivity indicies were also assessed according to variables related to work such as working hours, paryment for the workers, volume of feeding, utilization of foodservice equipment, use of processed foods, and background of employees. The summary of the results was as follows: 1. Manufacturing sector among surveyed industry foodservice showed the highest labor productivity indicies followed by training institute. 2. 28.8% of surveyed establishments used dishwashing machine, while manual dishwashing was used in 71.3% of subjects, equipped rate point was 9.8 out of 20, and disposable dish was used in 30% of subjects. 3. A significant positive relationship was found between the number of meals and the labor procductivity indicies. As the number of meals increased, more meals were served per worker as per labor hour. 4. A significant negative relationship was found between price of meal and the labor productivity didicies. As the price of meal increased, less meals were served per worker as well as per labor hour.

EES System support to maximize equipment efficiency by providing real-time information of main equipment which has a significant effect on product quality and productivity, and to prevent equipment failure by detecting equipment abnormality in advance. Smart Equipment Engineering System(S-EES) integrates the activities performed at equipment that are the core of production activities and manages them by system so as to maximize the efficiency of equipment and raise the quality level of products to one level. In other words, when the product is put into the equipment, the recipe is downloaded through the RMS, the recipe is set to the optimal condition through R2R(process control), and the system detects and controls the abnormality of the equipment during operation through the FDC function in real time it means. In this way, we are working with the suitable recipe that matches the lot of product, detecting the abnormality of the equipment during operation, preventing the product from being defective, and establishing a system to maximize the efficiency through real-time equipment management. In this study, we review the present status and problems of equipment management in actual production lines, collect the requirements of the manufacturing line for the PCB line, design and develop the system, The measurement model was studied.

도저는 고가의 건설장비로서 건설토공현장 정지작업에서 커다란 영향을 가져온다. 이러한 중요성에 따라서 머신 가이던스 시스템이 도저에 적용되어 토공 정지작업의 성과를 올리기 위한 노력이 진행되고 있다. 머신 가이던스 시스템은 정지작업 시 장비기사에게 정지작업에 필요한 굴삭깊이, 경사각도 등 정보를 제공하며, 장비기사는 제공되는 정보를 이용하여 측량기사의 도움을 최소화 하면서 정지작업을 진행할 수 있다. 이와 같이 머신 가이던스 시스템은 장비기사가 계획도면 상의 계획고에 맞추어 정지작업을 수행할 수 있도록 돕는 기능을 제공한다. 본 논문의 목적은 머신 가이던스 시스템이 기존 토공 정지작업과 비교하여 토공 정지작업에 가져오는 성과향상을 분석하는 것이다. 성과분석은 1) 생산성과 2) 정확도 2가지 관점에서 수행됐다. 여기서 생산성은 단위시간에 도출되는 작업량을 나타내며, 정확도는 계획도면에서 요구하는 계획고에서 벗어나는 정도를 나타낸다. 본 연구목적을 달성하기 위해 도저 머신 가이던스 시스템을 테스트 현장에 적용했으며, 적용결과 머신 가이던스 시스템이 전통적인 방법과 비교하여 생산성의 경우 46.59%, 정확도의 경우 46.96%만큼 증가되는 성과향상을 확인할 수 있었다.

종래의 깎기식 제거기에 의한 노면표시 제거작업은 인력에 의존하는 단순반복 작업으로 진행된다. 따라서 교통사고, 잔재제거에 사용되는 프로판 가스의 폭발, 작업자의 건강과 환경에 위해한 먼지와 유해가스 발생 등 위험요소가 상존하고 있다. 이러한 노면표시 제거작업의 문제점은 자동화 로봇화의 잇점으로 작용될 수 있다. 본 연구에서는 초고압수를 이용한 모바일 타입 노면표시 제거장비의 프로토타입을 개발하였다. 그 결과는 다음과 같다. 첫째, 현행 노면표시 제거작업 분석결과 노면표시 제거작업은 a)작업준비, b)노면표시제거, c) 현장정리로 구분할 수 있다. 이들 중 b) 노면표시제거작업의 전 공정을 수행할 수 있는 건설기 계장비가 필요함을 알 수 있었다. 둘째, 개발장비는 1일 8시간 작업 기준으로 약 1,400m를 작업할 수 있는 것으로 나타났다. 이 값을 기존방식의 작업량과 비교한 결과 280.0%의 생산성 달성 비율을 얻을 수 있는 것으로 분석되었다.
