Location area planning (LAP) problem is to partition the cellular/mobile network into location areas with the objective of minimizing the total cost in location management. The minimum cost has two components namely location update cost and searching cost. Location update cost is incurred when the user changes itself from one location area to another in the network. The searching cost incurred when a call arrives, the search is done only in the location area to find the user. Hence, it is important to find a compromise between the location update and paging operations such that the cost of mobile terminal location tracking cost is a minimum. The complete mobile network is divided into location areas. Each location area consists of a group of cells. This partitioning problem is a difficult combinatorial optimization problem. In this paper, we use particle swarm optimization (PSO) to obtain the best/optimal group of cells for 16, 36, 49, and 64 cells network. Experimental studies illustrate that PSO is more efficient and surpasses those of precious studies for these benchmarking problems.

The subject of navigation has drawn a large interest in the last few years. Navigation problem (or path planning) finds the path between two points, source location and destination location. In smart cities, solving navigation problem is essential to all residents and visitors of such cities to guide them to move easily between locations. Also, the navigation problem is very important in case of moving robots that move around the city or part of it to get some certain tasks done such as delivering packages, delivering food, etc. In either case, solution to the navigation is essential. The core to navigation systems is the navigation algorithms they employ. Navigation algorithms can be classified into navigation algorithms that depend on maps and navigation without the use of maps. The map contains all available routes and its directions. In this proposal, we consider the first class. In this paper, we are interested in getting path planning solutions very fast. In doing so, we employ a parallel platform, Reconfigurable mesh (R-Mesh), to compute the path from source location to destination location. R-Mesh is a parallel platform that has very fast solutions to many problems and can be deployed in moving vehicles and moving robots. This paper presents two algorithms for path planning. The first assumes maps with linear streets. The second considers maps with branching streets. In both algorithms, the quality of the path is evaluated in terms of the length of the path and the number of turns in the path.

주한미군 기지이전사업에 따른 평택 캠프 험프리스 주변으로는 많은 영외거주 수요가 있다. 이에 따른 영외주택 주거계획을 위해서는 그들의 요구사항이 반영된 계획을 수립할 필요가 있다. 그러나 그들의 요구사항을 직접적으로 조사한 연구는 전무한 것으로 파악된다. 본 연구에서는 캠프 험프리스에 주둔하고 있는 미군을 대상으로 그 요구사항을 조사 분석하여 그들의 요구사항을 정확히 파악하는 것을 목적으로 한다. 일반적으로 주거계획을 위해서는 수요에 기반을 둔 입지와 단지규모의 결정, 단지계획에 필요한 시설요소의 파악, 건물계획에 필요한 상세한 건축계획요소에 대한 분석이 필요하다. 이 중 본 연구에서는 수요와 입지선호도, 단지계획요소의 선호도 분석을 수행하였으며, 건축계획요소에 대하여는 후속연구로 남겨놓았다. 분석결과 영외거주의 수요도가 높고, 임대주택을 선호하는 것으로 나타났으며, 입지에 있어서는 통근시간이 가장 중요한 요소로 작용하고 있음을 파악할 수 있었다. 또한 도시적 편의를 누릴 수 있으면서도 자연에 가까운 산자락 부분의 입지를 선호하고 있음을 파악할 수 있었고, 향에 대한 중요도는 낮게 나타났으며, 한국인들과 어울려 사는 것도 문제가 되지 않았다. 아울러 단지 내 시설로는 운동시설에 대한 요구가 높은 편으로 나타났다.

This study aims to integrate the simulation models for rural settlement planning (SimRusep) in the district level (Myon) area of rural counties. The SimRusep, which has two modules of key villages selection and spatial planning for the selected villages, consists of four sub-models such as the spatial location-allocation model of center villages (SLAMCV), the potential centrality evaluation model (PCEM), the land use planning model (LUPM), and the 3-dimensional spatial planning modeller (3DSPLAM). Basically, map data of the integrated system which can be operated on the UNIX environment is inputted and treated using GIS (ARC/INFO) and then its village planning results is graphically presented on the AutoCAD. In order to verify the practical applicabilities of the SimRusep, an administrative area, Ucheon-myun, HoengSung-gun, KangWon-do, was selected as a case study area. It was well operated in the strategic application trials considering application of each sub-model in the study area. The operation results of the SimRusep showed the possibilities of realtime simulation from the selection of key village to its final stereoscopic presentation of planned results. Alternative village plan proposals can be swiftly drafted, which means very practical support for decision making process and public participation.

현재, 국토해양부 건설기술혁신사업의 일환으로 2006년 말부터 토공자동화를 위한 '지능형굴삭시스템개발'이 진행되고 있다. 지능형 굴삭시스템의 세부핵심요소기술 중, Task Planning System(TPS)은 토공 작업의 효율성, 안전성, 경제성 등을 고려하여 토공 설계데이터와 작업환경 인식기술에 근거한 작업환경 데이터를 분석하여 최적의 작업계획을 수립하는 시스템이다. 작업계획생성 시 효율적인 토공작업을 위해서는 플랫폼 생성 시 그 위치가 최적의 점을 형성하여 중첩되는 작업영역의 크기가 줄어들어 비효율적인 작업을 제거할 수 있으며 작업 시간을 최소화할 수 있고 굴삭작업의 생산성을 극대화찰 수 있다. 또한, 최적 플랫폼 위치 선정 시 굴삭기 제원에 따른 최적화가 되어야 굴삭기의 규격에 따른 로컬 영역의 산출 알고리즘과 호환이 될 수 있다. 본 논문은 영역 분할 과정에서 산출된 로컬영역을 기준으로 굴삭기 제원에 따른 최적화된 플랫폼 위치 선정 방안에 대하여 살펴보고 검증을 통하여 효율성을 판단하고자 한다.

The competitiveness of container terminals hinges on minimizing the time vessels spend in port and on schedule services. Many previous researches on container terminals have tried to optimize the equipment allocation plan and to improve the activity of resources. Nevertheless, there have been few researches conducted on yard tractors, which move containers between the quay and the yard. The aim of this study is to propose the use of Real Time Location Systems (RTLS) based Dynamic Planning for yard tractors. Only RFID (Radio Frequency Identification) tags, which are attached to yard tractors, are able to support RTLS implementation. The system can provide real time job ordering in terms of load balancing using the information on location, in regards to the movement of yard tractors. This study will present the practical feasibility of RTLS, which can ultimately reduce the congestion of Hot Queues in container terminals. As a result, container terminals can be more productive and competitive. In order to accomplish the purpose of this study, we examined previous studies on the competitiveness of container terminals and summarized the potential of RTLS using RFID. In addition, we identified the role of yard tractors and proposed the two rules of Dynamic Planning for the yard tractors. We then fulfilled computational experiments on how yard tractors carrying containers by RTLS ordering Finally, the benefits and the implications of this study are discussed.

To ensure that the production system of a factory is efficient, the factory layout design should consider the location and material flow plans of facilities, workshops, and storage areas. Highly productive factories need to have an optimized layout planning process, and a customized design methodology of the production system is a necessity for feasible layout planning. This paper presents a method for designing a layout module's size and shape and provides a heuristic location-allocation algorithm for the modules. The method is implemented and validated using a rich internet application-based platform. The layout design method is based on the leisure ship production process; this method can be used for designing the layout of a new factory or remodeling an existing factory and its production system. In contrast to existing layout methods, the inputs required for the proposed method, such as target products, production processes, and human-resource plans, are simple. This layout design method provides a useful solution for the initial stage of factory design.

This study aims to build a model dealing with the location decision of new manufacturing firms and their land demand. The model is composed with 1) the binary logit model structure identifying a future probability of manufacturing firms to locate in a city and their land demand; and 2) the land use suitability of the land demand. The model was empirically tested in the case of Anseong City. We used establishment-level data for the manufacturing industry from the Report on Mining and Manufacturing Survey. 48 industry groups were scrutinized to find the location probability in the city and their land demand via logit model with the dependent variables: number of employment, land capital, building capital, total products, and value-added for a new industry since 2001. It is forecasted that the future land areas (to 2025) for the manufacturing industries in the city are $5.94km^2$ and additional land demand for clustering the existing industries scattered over the city is $2.lkm^2$. Five industrial complex locations were identified through the land use suitability analysis.

This study was attempted to provide a scientific basis for the problem of location selection by spatial scale for efficient promotion of projects related to green care farm complex. Location potential assessment system in local government scale consists of two major components from demand-side and supply-side consideration. The demand-side aspect considered the characteristics of potential users, while supply-side aspect used total 18 indices over 8 divisions under 3 fields. For the location potential assessment in district scale, total 8 indices under 3 major divisions were considered based on biological, physical, social, and economic environment. The application results of the location potential evaluation system in local government scale(excluding metropolitan cities) showed high location potential in southern Gyeonggi Province and near Busan Metropolitan City. As a result of applying the district-scale location potential evaluation system to Geumsan-gun, Geumsan-eup, Chubu-myeon, and Jewon-myeon have high potential. Further studies to improve the applicability of the developed indices are recommended by enhancing assessment indices, complementing base data, and reinforcing with spatial analysis.
