This study developed a GIS-based suitability assessment model of coastal zoning system that is needed in the substantial classification of coastal zoning system according to the establishment of law about coastal zoning system. First, this study investigated several kinds of regulations, GIS database and application system related coastal area. Also, grid data model was selected as the GIS analytical model for calculating items of suitability assessment of coastal zoning system. And Grid-based analytical method was suggested for calculating items composing of sea and spatial location characteristics including physical one. Critical values of items were presented using standards that were suggested in coastal regulations and land suitability assessment. Especially, this study presented a calculation method of continuous pattern as fuzzy set function for reflecting the characteristics of GIS data. And this study classified the suitability grade using Z-score and developed model designating coastal zone as conservation management priority, utilization management priority, and planning management priority. This study is judged that very efficient business performance is possible if we consider the spatial coverage of study area and GIS database when the suitability assessment model of coastal zoning system that is suggested in this study, is applied to business works.

The purpose of this study is to develop an efficient BIM-based FM(Facility Management) system architecture to integrate the heterogeneous solution data related to FM. The heterogeneous solution data can be an FM system, asset management system, or facility sensor database systems, as well as files created by a modeler. In this study, we define the consideration for the external heterogeneous data integration related to BIM-based FM and propose the methodology. To implement it, trends in related studies were reviewed and general use cases of BIM-based FM were derived to develop the architecture for the integration between BIM and the heterogeneous solution data. The component architecture was designed to implement the use cases, and the schema was developed for the prototype by using the proposed architecture.

While occasional disasters have occurred recently in urban facilities such as bridges, buildings, subways, roads and others, the systematic safety management of urban facilities is greatly needed to prevent the disaster or to minimize the damages. This study proposes the way of setting-up and managing an building disaster information system so that this experience can be applied to other urban facilities to minimize trials and errors. With such a purpose, this study presents a building safety management information system and utilizes it for the building disasten information system. This study includes research agendas as follows : building maintenance and management infonnation system, setting-up and utilization the building safety management infonnation system, building disaster infonnation system using GIS. The results suggest that the building safety management infonnation system which can be related to the urban disaster infonnation system should be constructed in advance in order to utilize the building disaster infonnation system, and that, under this condition, it proved to be easily connected to the related database, especially GIS. And, to utilize such an infonnation system, the application programs such as safety evaluation program, cost estimation program and documents management program should be readily available. In addition, other functional programs related with maintenance and management should be designed and established. The schemes or devices for practical usage should be supplemented through a standardization and a pilot project in central government or Seoul Metropolitan Government level in order to set up and utilize the building safety management infonnation system, and the related laws or regulations should be prepared or amended to support the system.

It is a well-known fact that groundwater is difficult to be recovered, once it is polluted. Since its damage may continue for a long time, its management is very much necessary. For groundwater pollution managemet, current groundwater quality should be analyzed and its diffusion should be estimated. Such analysis and estimation are greatly enhanced by a GIS. In order to build the GIS, groundwater information management system, various database related to groundwater should be constructed. The system can be utilized to analyze groundwater quality and to help administrative processes of groundwater management. In this study, we analyze No3N diffusion in the groundwater under the study area, a part of Jung-Gu area, by using groundwater analysis subsystem and create the 1/5,000 scale map for the diffusion prediction of groundwater pollution. Although Seoul Metropolitan Government has constructed the 1/25,000 scale hydrogeology map of Seoul area through basic groundwater survey in 1996, the survey data are not sufficient for local groundwater pollution management. The large scaled map constructed in this study is expected to be utilized for the management. The GIS softwares, Arc/Info and Arc/View, are used. MODFLOW and MT3D programs are extensively used to analyze groundwater pollution.

As there comes out better and better solutions for delivering multimedia data on the internet, the number of WebCAM sites which transmits pictures of any spot to the user's system is getting increased. WebCAM service over the internet can be compared with the CATV in that it is beyond the spatial constraints. In this project, we construct a WebCAM site Which performs not only the fundamental WebCAM functions of capturing images and of transmitting them periodically but also various kinds of modules carrying out tasks such as image processing, remote control of the camera, processing multiple user requests, making panorama views and so on using Java which is the most popular language for the internet or CGI. The past images are stored in a database implemented for the WebCAM system, so the system can be extended to get over the constraints in time also.

Logistics optimization problems related with vehicle routing such as warehouse locating, track scheduling, customer order delivery, wastage pickup etc. are very interesting and important issues to date. Many Vehicle Routing and Scheduling Systems (VRSS) have been developed/proposed to optimize the logistics problems. But majority of them are dedicated to a particular problem and are unable to handle the real world spatial data directly. The system developed for one problem may not be suitable for others due to inter-problem constraint variations. The constraints may include geographical, environmental and road traffic nature of the working region along with other constraints related with the problem. So the developer always needs to modify the original routing algorithm in order to fulfill the purpose. In our study, we propose a general-purpose platform by combining GIS road map and Database Management System (DBMS), so that VRSS can interact with real world spatial data directly to solve different kinds of vehicle routing problems. Using the features of our developed system, the developer can frequently modify the existing algorithm or create a new one to serve the purpose.

In the ship building industry various problems of erection is counterfeited due to formation of bottle necks in the block erection flow pattern This kind of problems cause accumulated problems in real-time erection right on the floor, When such a problem is approached, a support data of the entire erection sequence should be available, Here planning is done by reasoning about the future events in order to verify the existence of a reasonable series of actions to accomplish a goal. This technique helps in achieving benefits like handling search complications, in resolving goal conflicts and anticipation of bottleneck formation well in advance to take necessary countermeasures and boosts the decision support system, The data is being evaluated and an anticipatory function is to be developed This function is quite relevant in day to day planning operation. The system updates database with rearrangement of off-critical blocks in the erection sequence diagram, As a result of such a system, planners can foresee months ahead and can effectively make decisions regarding the control of loads on the man, machine and work flow pattern, culminating to an efficient load management. Such a foreseeing concept helps us in eliminating backtracking related adjustment which is less efficient compared to the look-ahead concept. An attempt is made to develop a computer program to update the database of block arrangement pattern based on heuristic formulation.
