In this paper, we analyze a time-based update method in location management and calculate the optimal time-interval. We obtain the probability that an MT is j rings away from the center cell. And using these values, an exact analysis is made for the time-based location management cost. From the result, when the time-based method is applied to location update, we can get the optimal time-interval which minimizes the location management cost.

HLA는 이기종 시뮬레이터간의 연동을 위한 상위레벨 개념으로서 IEEE 1516 표준이며 Run-Time Infrastructure(RTI)는 이를 구현한 라이브러리 형태의 소프트웨어이다. RTI의 시간 관리 서비스를 개발함에 있어 효율적인 설계와 GALT 계산 알고리즘은 반드시 고려해야 하는 사항이다. 그러나 기존의 많은 RTI의 시간 관리 서비스는 수정과 확장이 용이하지 않다. 몇몇 RTI가 이러한 단점을 극복하기 위하여 모듈화 설계방안을 제안하고 있지만 이들은 IEEE 1516 HLA/RTI에 적합하도록 설계 및 구현된 것이 아니라 HLA 1.3을 위한 것이었다. 많은 RTI는 GALT 계산 알고리즘으로 분산 시뮬레이션에서 널리 알려진 Mattern의 알고리즘을 이용하고 있다. 그러나 Mattern의 알고리즘을 IEEE 1516 HLA/RTI에 적용시키기에는 몇 가지 제약사항이 존재한다. 본 논문은 IEEE 1516 HLA/RTI를 만족하는 시간 관리 서비스의 모듈화 설계를 제안하고 이를 바탕으로 구현한다. 시간 관리 서비스 모듈을 TIME 모듈과 GALT 모듈로 나누는 설계방안을 제안하고 GALT 계산 알고리즘으로는 Mattern의 알고리즘을 수정 보완하였다. 그리고 제안한 설계방안대로 구현한 시간 관리 서비스 모듈의 성능을 살펴보기 위하여 실험을 수행하고 그 결과를 분석하였다.

All sorts of technique for schedule progress management is being developed recently, These can change and develop the abstractive concept model to a detailed model that describes the visual 3D image about a schedule plan. but, this technique is troublesome, because this requires the handwork by means of connection between 3D-CAD and scheduling Program. In this study, the process of real-time schedule progress control system using the integrated database by 3D-CAD object information system and schedule module is presented. This study present the process of a schedule progress management using UML, and the process of real-time schedule progress management using RFID system. Through this study, we want to realize the rapid generation of estimated schedule information and to simulate and analyze actual schedule information by real-time.

The purposes of this study were to: a) investigate the percentage distribution and the time spent of dietetic activities and b) estimate dietitian's staffing needs in employee foodservices. In 6 employee foodservices, the dietetic activities were analyzed by work sampling methodology. The results of this study were as follows: 1. The percentage distributions of dietetic activities, delay and non-dietetic activities were 79.06, 20.39, and 1.55%, respectively; 2. The major activities of dietitians in employee foodservice were production management 21.00%, purchasing management 16.73%, record keepig 14.40%, and menu management 6.30%, 3. The total labor time per week was 3,310 min (55.16 hr) and specially the time spent on 13 dietetic activities was 2,626 min (43.77 hr). 4. The time spent per week on major activities of dietitians such as production management, purchasing management record keeping, and menu management were 693.93, 554.83, 483.99, and 205.22 min, respectively.

The purpose of this ethnography is to describe and analyse the Korean full-time housewives' everyday domestic cares. For this purpose. The 11 full-time housewives in their thirties and forties from the middle class were interviewed with an unstructured questionnaire. The findings are as follows: The full-time housewives interpret their domestic cares as including housework, financial management and consumption behavior. They have heavy responsibility to fulfil the routine housework, squeeze their financial resources and balance their family consumption and their own consumption. So, their every day lift has its own uniqueness different from their counter partners'- husband's and employed married woman's. But even among full-time housewives, there are many differences in all these three activities of domestic cares.

During last two decades the transportation system has developed into very intelligent system with GIS, GPS and ITS. The practical transportation management system provides real time response module to manage the customer's order. We have surveyed research papers on the real time vehicle routing problem in last two decades to figure out the dynamic vehicle routing problem. The papers are classified by basic routing algorithms and by managing the dynamic events which are the order management, the routing re-optimization, the routing post-optimization and the waiting strategy.

This note discusses the inter-loss time ofan M/G/1/1 queuing system. The inter-loss time is defined as the time duration between two consecutive losses of arriving customers. In this study, we present the explicit Laplace transform of the inter-loss time distribution of an M/G/1/1 queuing system.

Supply chains for agricultural commodities with their various constraints such as production lead time, seasonal production, and methods of storage are limited in the extent to which techniques like Just-in-Time (JIT) inventory management can be applied. It is beyond the ability of producers to control harvest time and many agricultural products are perishable so that they can incur exceptional losses in storage if they are not handled correctly. This is a source of additional costs and inefficiency in supply chain management. The purpose of this study is to reduce or eliminate such sources of loss and inefficiency and to identify success factors for the JIT inventory management system where it can be applied for agricultural products. Where JIT techniques can be applied in supply chain management for agricultural products, costs such as transportation, inventory, and storage losses can be reduced with concurrent increases in efficiency. In the paper, some of the problems associated with applying JIT inventory control methods in supply chain management for agricultural commodities will be reported through a series of case studies.
