According to the actual situation of a university, the emergency evacuation simulation is modeled based on the physical sign, evacuation speed and personnel ratio using the pathfinder software.The experimental construction export utilization rate is compared with the preliminary simulation scenario. The simulation results show that the utilization rate of evacuation stairs and evacuation exits is significantly improved.The optimized solution can provide the most effective evacuation passage, and the research results can provide the basis for the rational planning and management of evacuation passage in university experiment building.

Most of the shipbuilding scheduling researches so far have been conducted with stress on the dock plan. That is due to the fact that the dock is the least extendable resource in shipyards and its overloading is difficult to resolve. However, once the dock scheduling is completed, it is also important to make a plan that make the best use of the rest of the resources in the shipyard, so that any additional cost is minimized. This study automates block allocation process by analyzing the existing manual process that designates production bays for the blocks during the midterm planning. Also, a planning scenario validation method is suggested, where block allocation scenarios based on diagrams are edited and simulated.

MBNQA(Malcolm Baldrige National Quality Award) was established in 1987 in order to promote the spread of TQM in U.S. Likewise, JQA(Japanese Quality Award) was set up in 1995 in order to upgrade the level of TQM activities in Japan. MBNQA and JQA are quite the same in their basic concepts, values, and the process of the examination, but they differ in the contents of the criteria. The objective of this study is to Identify the differences between MBNQA and JQA in terms of strategy planning category, Therefore, in this paper, strategy planning category is analyzed, especially its theoretical validity is examined by literature review. The major differences are as follows: JQA emphasizes strongly the evaluation process than MBNQA by requiring the measuring of the level of strategic achievement. On the other hand, in MBNQA, strategic objectives must be estimated by decision analysts techniques, scenario tools, and other statistical methodologies.

The optimal use of sonar systems for detection is a practical problem in a given ocean environment. In order to quantify the mission achievability in general, measure of effectiveness(MOE) is defined for specific missions. In this paper, using the specific MOE for detection, which is represented as cumulative detection probability(CDP), an integrated software package named as Optimal Acoustic Search Path Planning(OASPP) is developed. For a given ocean environment and sonar systems, the discrete observations for detection probability(PD) are used to calculate CDP incorporating sonar and environmental parameters. Also, counter-detection probability is considered for vulnerability analysis for a given scenario. Through modeling and simulation for a simple case for which an intuitive solution is known, the developed code is verified.

Informationization is fast progressing in Korean and the informationization of education is also moving ahead fast. With informationization of education going fast ahead, cyber education is also increasing. Given such scenario, we should establish countermeasures not only to accommodate the current curriculum but also to accommodate the surplus school facilities created by cyber education by compartmentalizing the classrooms for future life-long education, lease and sale in lots. In conclusion, the school construction plan should be established to systematically cope with the future changes systematically.

This paper describes the use of a highly interactive and inter-operative application for complex simulation environments, or Synthetic Environments (SE), as deployed for construction as Construction Synthetic Environments (CSE). Based on the High Level Architecture (HLA), this research focuses on implementing simulation technology in a software environment, COSYE, that will be the foundation for building CSE applications. This framework is discussed in the context of tunneling and industrial construction applications, including steel fabrication and pipe-spool manufacture. The framework is demonstrated using the NEST sanitary tunnel project in Edmonton, Canada, in which COSYE was used for scenario-based analysis and planning.

Autonomous berthing is a crucial technology for autonomous ships, requiring optimal trajectory planning to prevent collisions and minimize time and control efforts. This paper presents a two-phase, two-point boundary value problem (TPBVP) strategy for creating an optimal berthing trajectory for a twin-propeller, twin-rudder ship with autonomous berthing capabilities. The process is divided into two phases: the approach and the terminal. Tunnel thruster use is limited during the approach but fully employed during the terminal phase. This strategy permits concurrent optimization of the total trajectory duration, individual phase trajectories, and phase transition time. The efficacy of the proposed method is validated through two simulations. The first explores a scenario with phase transition, and the second generates a trajectory relying solely on the approach phase. The results affirm our algorithm's effectiveness in deciding transition necessity, identifying optimal transition timing, and optimizing the trajectory accordingly. The proposed two-phase TPBVP approach holds significant implications for advancements in autonomous ship navigation, enhancing safety and efficiency in berthing operations.

In this paperm we provide a plan of construction, employment and management of the Korean postal address database and discuss the design of to-be models for it. For the purpose, we adopt and modify the information strategy planning methodology to fit it into our study. We examine the managerial environments and limitations of the postal services and define the requirements as a result. The U.S. Postal Service (USPS) was chosen as the best practice for a benchmarking and gap analysis with its advanced management of address information. After analyzing the current status of the postal business processes and information systems used, we classify the products and the services of USPS by the process to which they are applied and propose a deployment plan. In order to design a to-be model, we define the operating and managing functions for the address database and specify the scenario according to the functions. By managing the address database and supporting the postal services, it could be possible to make the business competitive and satisfy the customer demands.
