The block assembly process takes more than half of the total shipbuilding processes. Therefore, it is very important to have a practically useful block assembly process planning system which can build plans of maximum efficiency with minimum man-hours required. However, the process plans are often not readily executable in the assembly shops due to severe imbalance of workloads. This problem arises because the process planning is done on block by block basis in current practice without paying any attention to the load distribution among the assembly shops. this paper presents the development of an automated hull block assembly process planning system which results in the most effective use of production resources and also produces plans that enable efficient time management. If the load balance of assembly shops is to be considered at the time of process planning, the task becomes complicated because of the increased computational complexity. To solve this problem, a new approach is adopted in this research in which the load balancing function and process planning function are iterated alternately providing to each other contexts for subsequent improvement. The result of case study with the data supplied from the shipyard shows that the system developed in this research is very effective and useful.

In this paper, we propose a simulation method based on backward simulation and process-oriented simulation to take into account the characteristics of shipbuilding production, which is an order-based industry with a job shop production environment. The shipyard production planning process was investigated to analyze the detailed process, variables and constraints of mid-term production planning. Backward and process-centric simulation methods were applied to the mid-term production planning process and an improved planning process, which considers the shipbuilding characteristics, was proposed. Based on the problem defined by applying backward process-centric simulation, a system which can conduct Discrete Event Simulation (DES) was developed. The developed mid-term planning system can be linked with the existing shipyard Advanced Planning System (APS). Verification of the system was performed with the actual shipyard mid-term production data for the four ships corresponding to a one-year period.

The concept of sustainable development in rural area, which is focused on both preservation of nature and human's amenity, has been common paradigm. The purpose of this study is to suggest the development directions for the environmentally friendly rural house. The planning items for developing sustainable rural house were selected through literature survey, case study, and their adaptation evaluation. The establishment of principles and the evaluation of planning items were analyzed by a survey to experts. The results are as follows : 1) It is showed that sustainability evaluation of rural village is rated as above the moderate degree, but rural house is rated as 3.4(average score). Especially, there were lowly evaluated the utility, material, structure and inner environment in rural house. 2) It is revealed that 76.7% of planning items are located in both the upper left and upper right hand quadrant of the action grid, which is drawn by the importance-performance analysis(IPA). And any item is not found in the lower right hand quadrant(Possible Overkill). 3) Two basic principles and eight optional principles we identified by analysis of factor and regression. The rural zone is identified as major effective element for applying planning items into the rural house development. So it is desirable to apply the items differently by the rural zone type. 4) In view of sustainable development, it is desirable for rural village to have about 50 houses, and for rural house to have $155{\sim}180$ pyung(坪) as lot size, 30% as ratio of building, and 60% as building volume.

Long-term unexecuted urban parks will be released from urban planning facilities after 2020, this may result in development of those parks. However, little research have been focused on how to develop those parks considering conservation, development, spatial pattern, and so on. Therefore, in this study, we suggested an optimization planning model that minimizes the fragmentation while maximizing the conservation and development profit using ACO (Ant Colony Optimization). Our study area is Suwon Yeongheung Park, which is long-term unexecuted urban parks and have actual plan for private development in 2019. Using our optimization planning model, we obtained four alternatives(A, B, C, D), all of which showed continuous land use patterns and satisfied the objectives related to conservation and development. Each alternative are optimized based on different weight combinations of conservation, development, and fragmentation, and we can also generated other alternatives immediately by adjusting the weights. This is possible because the planning process in our model is very fast and quantitative. Therefore, we expected our optimization planning model can support "spatial decision making" of various issue and sites.

The purpose of this study is to analyze the development and characteristics of movable-housing planning concept. A document research method was used to analyze and classified the development of the movable-housing concept of 20th century. Through this study, the following conclusions have been reached; First, the origin of the movable-housing is from the prehistoric and traditional portable buildings, also due to the emergence of nomadic lifestyle using car traveling and mobile home in the 1920's. Second, the development of the movable-housing in 20th century was classified as follows; (1) In order to obtain the productivity and efficiency drawing from the industrialized-housing in the early of 1900s, movable furniture and flexibility was proposed. (2) American mobile home in 1920's, influenced by the development of car industry, was the most successful example of a factory-built building to be found in the world. (3) Dymaxion house and dome by R.B.Fuller, an aggregation of high-tech mechanical equipment, had a great impact on the development the concept of 'mobility' and influenced Archigram & Metabolist's movable capsule ideas in 1960's. (4) The lightweight materials such as plastic, duralumin and pneumatic structure were adopted for movable-housing in 1960's. Through this research, It is discovered that the stage of social development has close links with the developing aspects of movable-housing concepts. This study shows that the combination of three planning concepts such as flexible housing, mobile-housing and capsule will be more ideal in movable-housing planning rather than relying on just one type.

The purpose of this paper was to figure out the status quo of development of textiles in fashion industry by analyzing through in-depth interview with domestic women's wear converters on the process of textile planning. Professionals in top3 domestic women's wear converters were selected and interviewed in-depth on actual work process of textile development. The result of the research is as follows. First, the interviewed converters were having transactions with entire domestic target market of women's clothing and also exporting to China. Second, production of textile was mostly domestic, with some from China. Third, the number of textile development was 20 - 50 items per season accordingly to size of converter, and the number was larger if taking into account the sourcing development, the special finished fabric development and the print design development. Fourth, for methods to gather information, converters got ideas through overseas exhibitions, overseas color swatch books, fashion-related web sites and market research. Fifth, when setting up direction of textiles, it was investigated that they had motif from in-trend material or on previous season's best-selling material. Sixth, textile planning map did not start from early in season but prefers in-progress board map. Seventh, ways for many method types for textile planning were found depending on sales type of converter and textile production price.

As social needs are increasing to minimize the occurrence of external effect due to urban development and to diffuse the benefits of development to surrounding areas, diverse cooperative planning methods are increasingly being discussed. In the long term, laws and systems need to be refined to support cooperative planning, but prior to such development, elements, procedures, and methodologies wherein cooperative planning in U.S.A cases could be implemented were examined to derive the alternative to and implications of cooperative planning that can apply not only to single administrative districts but also to complex boundary new towns being developed by various local governments. This paper surveyed and analyzed the cases of Wisconsin State of the U.S.A, thereby deriving the following implications. First, joint planning areas should be established within the boundary area of various local governments to establish cooperative planning areas in special areas such as complex boundary new towns, and to this end, urban planning means should be prepared. Together with such efforts, to boost the flexibility of cooperative planning, life sphere unit-based planning unit should be established, and a well-organized operation system to activate communities should be prepared. Also, revenues, generated through regional growth, should be distributed to individual local governments through joint tax according to the agreed-upon ratios, and as such, measures to share services and operate joint tax in small-size regions should be secured. Together with such efforts, to establish cooperative governance, measures to manage conflicts through the participation by stakeholders and arbitrators should be prepared from the planning stage, and measures for implementing cooperative planning at the level of basic urban planning should be prepared.

The drastic change of spatial structure in rural area and the recent rural development policies(related to settlement reorganization and plot rearrangement) make the rural space planning more important than ever. So this paper tries to evaluate the institutional aspects of rural spatial planning system focused on planning area. land use classification and hierachical order between existing plans. The results of this study can be summarized as follows. First, the rural planning areas are classified into 4-tiers(e.g., Gun, Myon, District, Village). Second, the rural land use planning has 3-tiers(e.g., macro, mediate and micro zoning) from the viewpoint of land use classification system, but it doesn't have mediate-micro zoning system. Third, the spatial plans in rural area, positioned in local planning, were categorized into regional planning system and land use planning system. However there's no linkage between both sides of each hierachial planning order.
