In Postal logistics, the efficient design and operation of transportation network is very important issue. But, it is hard to operate the postal transportation network flexibly according to the change of mail volume. In Korea post, a transportation plan is pre-determined and the transportation of mail is performed through the routes in the plan. When the routes cannot transport all mail, temporary vehicles are used. In the postal transportation, it is important to make a good transportation plan and to manage the plan efficiently. But the change of transportation plan is not a simple work because hundreds of vehicles and persons are related to the plan. So, a methodology to check the effect of the change of the transportation plan in advance is required. In this paper, we develop a simulation model to evaluate the performance of a postal transportation plan. We implement the simulation model and develop an information system including user interface for managing data and simulation results. We apply our simulation model and system to the real change of transportation plan.

Typical highway infrastructure systems include roadway pavement, drainage systems, tunneling, and other hardware components such as guardrails, traffic signs, and lighting. Tunnels in a highway system have provided significant advantages to overcoming various natural challenges including crossing underneath bodies of water or through mountainous areas. While only a few tunnel failure cases have been reported, the failure rate is likely to increase as these assets age and because agencies have not emphasized tunneling asset management. A tunnel system undergoes a deterioration life cycle pattern that is similar to other infrastructure systems. There are very few agencies in the United States implementing comprehensive tunnel asset management programs. While current tunnel asset management programs focus on inspection, maintenance, and operation safety, there is an increasing need for the development of a comprehensive life cycle tunnel asset management program. This paper describes a conceptual framework for a comprehensive tunnel asset management program. The framework consists of three basic phases including a strategic plan, a tactical plan, and an operational plan to provide better information to the decision makers. The strategic plan is a basic long term approach of tunnel asset management. The tactical plan determines specific objectives and the operational plan actually applies asset management objectives in practice. The information includes operational condition, structural condition, efficiency of the system, emergency response, and life cycle cost analysis for tunnel capital improvement project planning.

For the office work environmental design, the importance of the design management is increased to improve operation efficiency as well as the aesthetic environmental implementation of the function today. Lighting is a required element ineffective operation environment. It has become more important for the aesthetic, economic, and practical reasons, to consider the luminous environment and the lighting of visual tasks separately. When the brightness is insufficient, productivity deteriorates, and the layout of the lighting located by mistake causes the fatigue of eyes. Productivity rises to office in a large number of studies so as satisfaction is low in general in the dark office, and to be bright. Therefore the purpose of this research is to suggest the right direction of lighting design of office building area. 11newly renovated office buildings are selected for this luminous environment research. We could conclusions as following through this research. First, it was planned brighter than the recommended lighting level in the most space. It shows that the accurate lighting design criteria is needed in order to achieve proper lighting environment. Second, the application of the LED lighting fixtures is continuously increased in the recent office lighting environment. It is explained that it is applied for reasons of the electrical energy reduction and the maintenance efficiency with the long life time. Third, the consideration of the lighting plan for the difference of working types is not enough. with various communication configuration through an independent plan, and the effective lighting plan that appropriateness preparation design and energy saving area vailable must be applied. Fourth, the lighting environment of the lobby needs a specialized lighting plan as are presentative space of the building.

Although Jeju is the best cruise Secondary port in Northeast Asia, currently there are no dedicated cruise terminals. The port international passenger terminal opened in 2015 has a ferry terminal for offshore passengers and a cruise passenger function. Jeju Island is therefore constructing a cruise only terminal with the aim of opening in 2018 to meet the growing passenger demand at the Seoguipo civilian and public ports along with construction of a naval base at Gangjeong Port in Seogwipo City. It also plans to build cruise docks and cruise terminals in the Jeju New Port according to the Jeju port construction basic plan. However, during the construction and planning process of cruise terminals in Jeju, the adequacy of the terminal size is being debated and the immigration facilities are being operated. Therefore, the study analyzed the size of terminals and operation of immigration facilities appropriate for cruise passenger demand by investigating the status of cruise related facilities and operation in Jeju area. Based on this, the Commission hopes to explore the rational direction of the cruise terminal plan to revive the cruise industry in Jeju and provide high quality service to cruise passengers.

In the past annual recycling obligation rate calculation of Extended Producer Responsibility (EPR) system, it was difficult to operate the system efficiently, because responsible producers passively participated in the scheme only bent on achieving annual obligation without long-term plan. Thus, a new scheme of long-term recycling obligation rate began to be established every five year from 2008 in order to give the basis for the notice of annual specific operation standard and recycling obligation, thereby helping responsible producers to make a preparation with a plan and giving expectation of active operation of the scheme. However, in the operation of long-term recycling target program, while the development of prediction models and the evaluation for existing items has been conducted in various ways, applications for a new target items and the evaluation are quite insufficient. Therefore, in this study, problems in implementing long-term recycling goal of new target items will be examined, and more objective and rational long-term recycling rate calculation and the operation standard will be proposed. Thus, the long-term recycling target will play a role as a pacemaker to steadily improve the recycling performance of target items, and responsible producers will be expected to increase the achievement with the realistic capacity.

This paper describes the development of an integrating method for process planning and scheduling activities for block assembly in shipbuilding. A block is composed of several steel plates and steel sections with the predetermined shapes according to the ship design. The parts which constitute the block are manufac- tured by cutting and/or bending operations, which are termed as machining operation in this paper. The machining operation is the first process for block assembly which influences the remaining block assembly processes. Thus process planning and scheduling for machining operation to manufacture parts for block are very important to meet the assembly schedule in the shipyard. An integrating method for process plan- ning and scheduling is developed by introducing the concept of distributed process planning and scheduling composed of initial planning, alternative planning and final planning stages. In initial planning stage, nesting parts information and machining emthods are generated for each steel plate. In alternative plan- ning stage, machine groups are selected and workcenter dispatching information is generated. In final planning stage, cutting sequences are determined. The integrated system is tested by case study. The result shows that the integrated system is more efficient than existing manual planning system.
