  • Connecting with cost, schedule, and quality in a construction project, resource management is one of the essential management elements. However, the material requirement planning is built at the beginning stage of construction and needs various concerned factors, it is limited to build the resource management planning on enterprise level. The disconnected communication among managements makes impossible to control historical data. In the construction project control system, the core of management elements is to manage cost and schedule information, therefore material requirement planning should be established based on historical data about EVM which is intergating schedule and cost. In this study, a resource management system concerning material requirement planning and attribute of procurement is suggested by connecting the historical data of EVM and the material requirement planning.

  • According to the change in diverse tendency of residents, construction companies has developed the brands of apartments with the concepts of LOHAS, well-being, ubiquitous, etc. The purpose of this study was to suggest space requirement and planning for residents characteristics. The questionnaire survey was adopted in this study and 252 cases were used for data analysis. The survey analysis has been made by using of SPSS WIN 12.0. The major findings were as follows; (1) Resident opinion about the direction of each space was investigated into the need of South-facing in master bedroom highly. (2) The residents didn't want to decrease the current size of each space, the space which wanted to increase was livingroom. (3) The significant variables of space requirement and planning for residents characteristics were family life cycle, the age of householder, the occupation of householder, the size of apartment.

  • It is the important accurately to identify the needs of our customers in order to success the project. Requirements in the early stages of business is very abstract or not quantitative, and that will cause problems such as cost or schedule changes. Particularly many people are likely to prefer the early stages of the project, because the time of applying VE related cost savings is important. Owner's requirement analysis for project success in the VE process does not easy, and specific ongoing management of the requirement is difficult. Therefore, the analysis and the application of owner's requirements is limited in project process. The purpose of this study is proposed to the RFM technique to supplement the functional analysis on the basis owner's requirements analysis in planning a building project.

  • The primary role of MRP(Material Requirement Planning) is to make a production plan so that we have an exact quantity of right materials on needed time at right place. But the ignorance on capacity constraints makes some problems whenever production schedule is established. To increase the performance of MRP system, a novel approach which is based on new input data structure is suggested. The new input data structure includes all the information about Material BOM, Routing and resource data so that we can easily examine the usage of resources and generate higher performance production plans.

  • Generating a project network of a specific construction project is very time consuming and difficult task in the field. To effectiviely automate and support the planning process, we design a case-based project planning expert system inspired by the fact a human expert project planner uses previous cases for planning a new project. A construction project case consist of its specific characteristics and the corresponding project network (i.e. project plan). Using frame based representation. we represent the project features affecting the progress network and the entities composing the project plan such as the buildings, construction methods, WBS (work breakdown structure), activities, and resources. The project planning process runs through most similar case retrieval, case adaptation, and user requirement satisfaction. We represent the construction domain knowledge for each procedure using constraints and rules. We develop the methodology for constraint-based case adaption. Case adaptation process mainly consist of activity generation/deletion and predecence constraint satisfaction, for which we develop the dynamic constraint generation method and connect user-level requirement representation the system-level network modification knowledge. The methodology is being applied to the prototype for apartment construction project planning.

  • In this paper, we propose an approach to get the requirement of drone acquisition for the efficient dronebot combat system using brute force algorithm. We define parameters, such as width, depth, and important surveillance area for the surveillance mission in the Army battalion and company units based on real military operation environment and brute force algorithm with 4 steps including first, next, valid, output is applied to get the requirement of drone acquisition and each drone's path planning using computer simulation. As a result, we could get the requirement of drone acquisition and each drone's path planning, the Army could utilize our proposed approach in the Army dronebot combat system. In the future research, we will study on the reliability of our proposed approach to get the requirement of drone acquisition for the efficient dronebot combat system.

  • With the cognition of the problems on propulsion system of rural development program, the requirement for accurate diagnosis of the problems and for reform scheme is increasing. This study was performed to solve the above requirement especially on the level of a local government, Chungnam province as an instance. For accurate diagnosis of the problems, the present situation of propulsion system, i.e. organization and governance, planning and policy making, implementation and supervision of rural development program was investigated, and the cognition of public officials and specialists was surveyed. From the study, it showed that the problems of propulsion system for rural development program in Chungnam province are duplication of work sphere among departments, formal administration of governance, an absence of long-term plan with vision and strategy, and absence of department in charge of comprehensive supervision and so on. As a result of the study 9 reform schemes to solve the problems were suggested.

  • Earned Value Management System(EVMS) is a management technique that is emerging as a valuable tool in the management of all projects, including and in particular construction projects. It is based on C/SCSC that has been released by the U.S. Department of Defense (DOD) in 1967. In a project that employs the earned value management concept, the project's measurable performance plans will be formed with the creation of CAPs. The formation of CAPs is a planning step necessary to form an earned value baseline. In this paper, a method is proposed to form CAPs using Material Requirement Planning(MRP) that is also known as a useful planning tool in the manufacturing industry. An application to a real project has been carried through workpackaging model.

  • In the construction industry, materials management is one of the most important components in construction engineering life cycle. Materials management optimization is one of the research subjects in the field of construction management. In the materials management system of a construction project, the suitability of selecting procurement planning strategy will influence the result of project completion. This study conducts literature review at first and also refers the related issue in other industry's application. Associated with the characteristics of construction project in civil engineering and the concept of object oriented design applied in the materials management, this research is aimed to establish a construction materials requirement preliminary system.

  • The purpose of this research is to develop the technology to meet the requirements of the design content, and to build a 'Requirement Information Management Model' for the design project. The model that should be used in the early design stage will undergo the following process: First, basic requirements would be defined by extracting the design content in the form of a reusable library of space units. At the next stage, requirement information should be modified after considering unique characteristics for the project and conflict problems between function and performance.
