In the Port Logistics system, Container Stowage planning is an important issue for cost-effective efficiency improvements. At present, Planners are mainly carrying out Stowage planning by manual or semi-automatically. However, as the trend of super-large container ships continues, it is difficult to calculate an efficient Stowage plan with manpower. With the recent rapid development of artificial intelligence-related technologies, many studies have been conducted to apply enhanced learning to optimization problems. Accordingly, in this paper, we intend to develop and present a Deep Q-Learning Network model for the Master Stowage planning of Container ships.

This study aims to find out the better management plan for city master plannning as an ODA to accomplish the economic effect. For this study, the "Hai Phong New Town Development Project" and the "Modification of Hue City's Master Plan" were studied. The result of the case study shows that there was difference between the two projects which was the status of following projects. While those two projects were highly acclaimed, only Hue project had several projects. This is because of the understanding degree on ODA project of participants, the distinct characteristics of the recipient country; Vietnamese local and central government, and the difference of each project's main purpose. And the result of FGI shows that to accomplish economic effects of master planning project as ODA, the enthusiastic approach to find out following project from the beginning step of the master planning, the experience of project manager on ODA, the close association with the recipient country, and the positive support from the Koica especially, the local office were crucial.

The purpose of this study is to analyze space composition and size of the Master Zone in the apartment unit plan. For this, we analyzed 435 samples by searching web-sites of the 5 main construction companies. The major results of this study are as follows. 1) Master Zone is organized 4 spaces such as main room, bathroom and make-up & dress room. Six types of Master Zone are classified with the composition of 4 spaces. 2) The size of the Master Zone is increased in proportion to the square meter. But the range of the ratio is small range of fluctuation as 20%${\sim}$30%. 3)The size and ratio of the each spaces of the Master Zone are analyzed. The size of bedroom is increased but the ratio is decreased. The size of bathroom is increased but the ratio is regular as 4%${\sim}$5%. The size of make-up and dressing room is generally increased but the range of the size and ratio is the most extensive. Through this analysis and research, this study would be provied the basic data for actual housing planning and to contribute to future trends of apartment houses.

In practice of urban redevelopment promotion projects, since the decision-making is dependent on the verbal agreements between the participants, planning changes are frequently occur. A master plan can be utilized as an effective feedback and adjusting means for decisions. It is a difficult to establish a master plan quickly and effectively to consider the large number of information. Effective decision support system that can storage and retrieval information items systematically and efficiently necessary when planning master plan is required. In this study, a data-warehouse prototype that supports the master planning at early stage was suggested. A metadata index database was developed by identifying information items of base survey results and master plan cases. Also user interface for information searching was presented. The applicability of the prototype was evaluated by case application. It was found that the prototype allows effective searching of desired information through meta data.

The Last PlannerSystem (LPS) has been implemented on construction projects to increase work flow reliability, a precondition for project performance againstproductivity and progress targets. The LPS encompasses four tiers of planning processes:master scheduling, phase scheduling, lookahead planning, and commitment / weeklywork planning. This research highlights deficiencies in the current implementation of LPS including poor lookahead planning which results in poor linkage between weeklywork plans and the master schedule. This poor linkage undetermines the ability of theweekly work planning process to select for execution tasks that are critical to projectsuccess. As a result, percent plan complete (PPC) becomes a weak indicator of project progress. The purpose of this research is to improve lookahead planning (the bridgebetween weekly work planning and master scheduling), improve PPC, and improve theselection of tasks that are critical to project success by increasing the link betweenShould, Can, Will, and Did (components of the LPS), thereby rendering PPC a betterindicator of project progress. The research employs the case study research method to describe deficiencies inthe current implementation of the LPS and suggest guidelines for a better application ofLPS in general and lookahead planning in particular. It then introduces an analyticalsimulation model to analyze the lookahead planning process. This is done by examining the impact on PPC of increasing two lookahead planning performance metrics: tasksanticipated (TA) and tasks made ready (TMR). Finally, the research investigates theimportance of the lookahead planning functions: identification and removal ofconstraints, task breakdown, and operations design.The research findings confirm the positive impact of improving lookaheadplanning (i.e., TA and TMR) on PPC. It also recognizes the need to perform lookaheadplanning differently for three types of work involving different levels of uncertainty:stable work, medium uncertainty work, and highly emergent work.The research confirms the LPS rules for practice and specifically the need to planin greater detail as time gets closer to performing the work. It highlights the role of LPSas a production system that incorporates deliberate planning (predetermined andoptimized) and situated planning (flexible and adaptive). Finally, the research presents recommendations for production planningimprovements in three areas: process related, (suggesting guidelines for practice),technical, (highlighting issues with current software programs and advocating theinclusion of collaborative planning capability), and organizational improvements(suggesting transitional steps when applying the LPS).

The purpose of this study is to examine the characteristics of housing planning in 23 wards of the Tokyo Metropolitan Area. First, the present residential conditions in the 23 wards were investigated. And then we analyzed the basic purpose and individual policies of Housing Master Plan in the 4 wards. In this study, it was found that the basic purpose of Housing Master Plan can be classified into three parts: amenity, safety, and diversity. Analyzing the individual policies, it was found that the priority are given to safety and diversity out of the those three parts.

Recently the number of rural development plans are increased and projects supported by government are various. These makes rural plans important. But there are many gaps between proposed plan and implementation. These gaps were wasteful in terms of resource management. This study examines differences between plan and implementation and the reasons why they are occurred. For this purpose, we did a case study which is focused on the four-year implementation of 2004-2006 "Unique Experience Village Master Plan" of Seochon, Chungbuk. As a result, we verified facts of gaps and causes, and two major causes were detected : one is the absence of operating and managing body(such as promoter of project, village leader, residences), and the other is inadequate master plan.

A collision-free trajectory planning algorithm is proposed to optimally coordinate two robots working in a common 3-D workspace. Each link of the two robots is modeled as a line segment and by their motion priority, one of the two robots is chosen as the master and the other the slave. And the one-step-ahead minimum distance between the two robots is computed by moving the master to the next location on its specified trajectory. Then the nominal trajectory of the slave is modified such that the distance between the next locations of the master and the slave must be larger than a prespecified allowable minimum distance. Here the weighted sum of the trajectory error and the joint motions of the slave is minimized by using the linear programming technique under the constraints that joint angle and velocity limits are not violated. To show the validity of the proposed algorithm, a numerical example is illustrated by employing a two dof's and a three dof's planar robots.
