  • Facility location planning (FLP) problem is the strategic level planning in supply chain. The FLP is significantly affected by the operation time of each facility. In most of the FLP researches, operation time of facility has been treated as a fixed value. However, the operation time is not a static factor in real situations and the fixed operation time may lead unrealistic FLP. In this paper, a mixed integer programming (MIP) model is proposed for solving the 3-stage FLP problem and operation times are adjusted by the results from the simulation model and an iterative approach combining the analytic model and simulation model is proposed to obtain more realistic operation plans for FLP problems.

  • The purpose of this study was to provide planning criteria for the thalassotherapy facility. Among the various contents of the planning criteria, the crucial parts of the thalassotherapy facility planning are the location, facility environment, and room space. To do this, we first examined the characteristics of the thalassotherapy facility and inquired about the thalassotherapy resources and treatments that are the basis of the thalassotherapy facility planning. And then, the overseas qualification criteria related to thalassotherapy facility were analyzed. Based on the above research results, the criteria for the thalassotherapy facility planning on location, facility environment, and spaces of rooms are presented. The location is within 1km of the coastline, where there is no pollutant emission facility, and the climate conditions are maintained more than 80% throughout the year below 'caution' level of the thermal sensation index and sensory temperature. The water quality of the facility environment meets the stricter criteria among the domestic standards or ISO 17680 standards, and the air quality is 60% of the atmospheric environment standard of the 「Framework Act on Environmental Policy」 and SO2, NO2, O3 and PM10 concentration shall ensure that the annual number of exceeding standards meets the EU standard, and noise is less than 50dB per daytime, 40dB per night. Therapy spaces have to meet the standards of the 「Building Act」, the working standards of architectural planning and international standards according to their function and use.

  • In this paper, a shared model of systematic urban facility construction planning system is proposed. As the scope of construction on urban facilities has expanded, the construction process may occur simultaneously in the same location and short period of time by the different public agencies. This kind of construction duplications may cause the inefficiency of construction time and cost. In order to improve this, we studied the sharing method of the construction information which are produced by the different construction agencies. And also studied the method of find out the duplicate constructions occurring in the same place and short period of time. And Then we suggest a system that can rearrange the order of urban facility construction.

  • The intent of this study is to investigate the current situations and planning implications of elementary schools in urban housing blocks, and to propose the planning and design guidelines for them. The premise of this research is that an elementary school should function as a communal facility, shared by its community, so called open-school. 32 schools in three new towns were selected as sample cases and they were closely surveyed in terms of their site planning issues in residential blocks, and three sample open-elementary schools were analyzed in a comparative manner for finding their roles and functional fulfillment as a communal facility in the neighborhoods. Based on the findings, several planning principles and design techniques or devices are suggested for the utilization of elementary schools by local residents, mainly making issues of location, relationship to other facilities and open spaces in residential blocks, access, apartment layout, school building and outdoor spaces, and open program.

  • The purpose of the study is to propose architectural design standards of the cafeteria planning in educational facilities. In the spatial organization planning, the preferred location of the cafeteria is on the first floor and the types of the floor plan are followed by the forms and space structure of the school building. The area of the cafeteria is related to the size of seating area per person. The direction must sublate northern faced. In interior moving lines for service, the arrange of dining tables has to reflect distance of dining tables or location of pillars. The dining space should better have more than two entrances in terms of occupancy type and convenience. Thus the serving line has to be planed thoughtfully by various factors to avoid confusion caused in serving process. In multipurpose use of the cafeteria, it is feasible when hygiene and management is considered.

  • In this research report, we propose a heuristic algorithm with some primal recovery strategies for capacitated facility location problems (CFLP), which is a well-known combinatorial optimization problem with applications in distribution, transportation and production planning. Many algorithms employ the branch-and-bound technique in order to solve the CFLP. There are also some different approaches which can recover primal solutions while exploiting the primal and dual structure simultaneously. One of them is a MVCD (Mean Value Cross Decomposition) ensuring convergence without solving a master problem. The MVCD was designed to handle LP-problems, but it was applied in mixed integer problems. However the MVCD has been applied to only uncapacitated facility location problems (UFLP), because it was very difficult to obtain "Integrality" property of Lagrangian dual subproblems sustaining the feasibility to primal problems. We present some heuristic strategies to recover primal feasible integer solutions, handling the accumulated primal solutions of the dual subproblem, which are used as input to the primal subproblem in the mean value cross decomposition technique, without requiring solutions to a master problem. Computational results for a set of various problem instances are reported.

  • To rapidly recover ceased functionality of a facility after a catastrophic seismic event, critical decisions on facility repair works are made within a limited period of time. However, prolonged damage assessment of facilities, due to massive damage in the surrounding region and the complicated damage judgment procedures, may impede restoration planning. To assist reliable structural damage estimation without a deep knowledge and rapid interactive analysis among facility damage and restoration operations during the approximate restoration project planning phase, we developed a prototype of distributed facility restoration simulations through the use of high-level architecture (HLA) (IEEE 1516). The simulation prototype, in which three different simulations (including a seismic data retrieval technique, a structural response simulator, and a restoration simulation module) interact with each other, enables immediate damage estimation by promptly detecting earthquake intensity and the restoration operation analysis according to estimated damage. By conducting case simulations and experiments, research outcomes provide key insights into post-disaster restoration planning, including the extent to which facility damage varies according to disaster severity, facility location, and structures. Additional insights arise regarding the extent to which different facility damage patterns impact a project's performance, especially when facility damage is hard to estimate by observation. In particular, an understanding of required type and amount of repair activities (e.g., demolition works, structural reinforcement, frame installation, or finishing works) is expected to support project managers in approximate work scheduling or resource procurement plans.
