Construction system modeling can enhance work performance by following the behaviors of a system. System behaviors may originate from physical aspects of a system, namely operation level variables, or from non-physical aspects of a system known as context level variables. However, construction system modelers usually focus on only one type of system variable (i.e., operation level or context level) which can lead to less accurate results. Hybrid modeling with System Dynamics (SD) and Discrete Event Simulation (DES) is one of the approaches that has been utilized to address this issue. In this research, an SD-DES hybrid model of a steel fabrication shop is developed, and the benefits of capturing context level variables together with operation level variables in the model are discussed.

From the perspective of the client, the value of information for use in facility management is very low at the point of use. This is because the facility owner, who is a non-professional, cannot accurately request necessary information from the perspective of long-term facility life cycle management. The purpose of this study is to define the information necessary for facility management and to analyze the project operation method to procur this information to the client using BIM. To this end, this study analyzed the role of client and contractor, project delivery process, standards, and submissions in the BIM-based procurement area through USACE Air Force Hospital project case analysis. As a result of the analysis, if the client, who is the subject of facility operation, defines in advance the type and input method of necessary information in the operation stage, the client can receive the BIM optimized for operation from the contractor. The results of this study can be used to establish standards for receiving information necessary for establishment of procurement process and facility management of public institutions considering BIM introduction.

Integrated operation schools were introduced to Korea in 1998 with an operation of eight schools, and their number has now increased to 106 and is still growing. Although various problems have been pointed out in research on integrated operation schools over the past two decades, these have not been reflected today. Therefore, the purpose of this study was to comprehensively summarize the concepts, backgrounds, recent status, types, etc. of the integrated operation school and to present its problems in terms of curriculum, teacher management, student management, operation and management of educational facilities, and law and policy through literature review and to propose measures for improvement. This allowed us to compare the concerns of the integrated operation school with the results of the actual research and organize improvement measures.

Energy consumption savings in buildings should be reviewed in diverse areas such as air conditioning system and lighting responsible for cooling and heating, and energy management systems such as BAS (Building Automation System) and BEMS (Building Energy Management System) are introduced to improve energy consumption efficiency and to promote economic control of related facilities by integrated management of energy generated and consumption in buildings. The measured building of this study uses regenerative geothermal system. Measured values of heat pump and system COP were 4.7 and 4.2 respectively, and they were found to be higher 11.9% and 23.5% than rated values. As a result of analyzing the air conditioning and lighting energy from the first floor to the fourth floor performing the air conditioning, the second and third floors, which have a high frequency of use, are compared with the first and fourth floors 50% higher energy consumption ratio. On the other hand, the general heat storage system uses the nighttime power of the previous day to store heat and use it the next day. The total number of days of abnormal operation during the summer season is 61 days. The electricity cost corresponding to the abnormal operation is 1,840,641 KRW, and the normal operation using the nighttime power is 1,363,561 KRW, which is difference of 477,080 KRW, 35% increase in cost. We will utilize it as the main data of BEMS through analysis of winter operation characteristics as well as summer operation characteristics.

This study examines the effectiveness of a new community facility operation and management system that were implemented by one of the major construction companies. This system was an unprecedented approach in a sense that it provided not only necessary facilities but also a specialized management staff, an operational manual, and a subsidy for various programs. According to POE conducted among the residents, it can be concluded that the residents' satisfaction will be increased under the following conditions; 1) when a program manual associated with the community facility is provided, 2) when there is a professional staff who can coordinate various programs effectively, 3) when the facilities are well designed in accordance with the program requirements, 4) when the users adhere to regulations and management standards, 5) when all three components- i.e. facility, people and programs- are well coordinated, and 6) when affordable user fees are charged. This research assures that professional management staff and well-planned management system play a significant role in the enhancement of the residents' satisfaction as well as vitalizations of the community.

By the newly emerging network access technology, we face the new heterogeneous network environment. Focusing on the co-existence of multiple access network technology and the complex service needs of users, the wireless service operators should present the stable service quality for every user. For this, the service operators should build the new operation framework which combine the pre-established network and newly adopted one. Our problem is finding the optimal heterogeneous network operation framework. We suggest market-based marginal cost function for evaluating the relative value of resource of each network and develop the whole new heterogeneous network operation framework. To test the applicability of developed operation framework, we build large-scale JAVA simulator. By this development, we can easily test the new network environment in practical engineering field.

Haul routes for earthmoving operation need to be carefully selected because the decision on the haul routes could make a significant difference in the project's cost and time. This paper proposes a decision support system for improving productivity of earthmoving operation that helps construction managers choose the best haul routes of trucks based on time slots. Also, a methodology for optimal selection of haul routes considering traffic conditions and topographic conditions of the routes is explained. Raster data model is used to find an available shortest path based on cost weighted distance. A system was developed on a geographic information system environment for efficient database management and easy manipulation of graphical data. A real-world case study was conducted to verify the applicability of the proposed system.
