Highly informative heuristics in AI planning can help to a more efficient search a solutions. However, in general, to obtain informative heuristics from planning problem specifications requires a lot of computational effort. To address this problem, we propose a Partial Planning Graph(PPG) and Mixed Heuristics for solving planning problems more efficiently. The PPG is an improved graph to be applied to can find a partial heuristic value for each goal condition from the relaxed planning graph which is a means to get heuristics to solve planning problems. Mixed Heuristics using PPG requires size of each graph is relatively small and less computational effort as a partial plan generated for each goal condition compared to the existing planning graph. Mixed Heuristics using PPG can find partial interactions for each goal conditions in an effective way, then consider them in order to estimate the goal state heuristics. Therefore Mixed Heuristics can not only find interactions for each goal conditions more less computational effort, but also have high accuracy of heuristics than the existing max and additive heuristics. In this paper, we present the PPG and the algorithm for computing Mixed Heuristics, and then explain analysis to accuracy and the efficiency of the Mixed Heuristics.

민간 개발 프로젝트의 초기 기획단계는 프로젝트 전체의 성패를 좌우하는 중요한 부분이다. 하지만 기존의 기획단계 분석결과의 신뢰도는 중요도에 비해 높지가 않다. 따라서 기존 민간 개발 프로젝트 기획단계의 사례연구 및 연구자료 분석을 통해 근원적인 문제점을 분석하였다. 그 결과 기획단계의 업무 절차나 방법에 관한 체계적 분석 모델의 구축이 되지 않은 것에 그 원인이 있는 것으로 나타났다. 이에 본 연구에서는 그 해결방법으로 기획단계 분석절차 모델과 리스크 관리 모델 구축을 통해 체계적 분석방법을 제시하고자 한다. 제시된 분석방법은 기획단계 분석결과의 신뢰성을 증대시킬 수 있을 것으로 기대된다. 이와 함께 프로젝트 진행단계별 가이드라인을 제시함으로써, 프로젝트의 효율적 수행을 지원할 것으로 기대된다.

Since 1949, the UK has implemented a national land planning strategy to sustain rural areas, emphasizing the concept of 'Natural Beauty.' This involves designating "Areas of Outstanding Natural Beauty (AONB)" as a political approach to conserving rural landscapes and fostering a societal consensus on environmental conservation. AONB adopts an integrated and systematic approach to achieve harmony between the environment and human activities. This study investigates the implications of the AONB rural landscape management approach through case studies of the Cotswolds Conservation Board and Cannock Chase Joint Committee. It examines the legislative designation and supporting processes of AONB, analyzing the governance system to clarify the roles of authorities in policy decision-making. AONB's system revolves around joint committees or conservation boards of local authorities responsible for establishing, implementing, and monitoring management plans. The planning process involves a harmonious management plan system reflecting regional demands, including regular forums. AONB serves as a powerful tool for local residents to engage in the development of their region through stewardship. The study suggests that understanding the AONB model could provide a foundation for developing rural landscape conservation and spatial management plans tailored to Korea's context in the future.

As ships become larger and construction of offshore plants increases recently, the amount of outsourcing has increased accordingly in the shipyard. Consequently, the system integration in terms of SCM (Supply Chain Management) of information and material flows has become much more important. Especially, since the SCM in the shipbuilding industry is operated in accordance with the production planning in connection with design, purchasing and production process which are the main components of the supply chain, the best production plan has to be established over the whole scheduling activities from the long-term planning to the short-term planning. The paper analyzes the characteristics of the SCM and the production planning system and suggests the need and the direction of APS (Advanced Planning System) development specialized in the supply chain management only for shipbuilding industry. Furthermore, propose a new SCP-Matrix (Supply Chain Planning Matrix), which is the basis of the APS development, appropriate for the shipbuilding industry and draw the core function of the APS module for the practical production plan.

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 purposes of this study were to (1) examine the sub-dimensions of time management behaviors and satisfaction with time management, and (2) to identify the variables that can affect satisfaction with time management. Data was collected through an Internet survey answered by 611 working men and women. The data were analyzed using descriptive statistics, factor analysis, and multiple linear regression analysis. As a result of the study, the sub-dimensions of time management behaviour were extracted into three subordinate categories, which were, planning, human relation orientation, and urgency. The sub-dimensions of the satisfaction with time management were extracted into three subordinate categories, which were, satisfaction with the management results, satisfaction with time distribution, and satisfaction of spare time. Management result satisfaction displayed a positive relationship with planning and work time. The satisfaction with time distribution displayed a positively relationship with planning, relations-intention, the level of education, and sleeping time, while displaying a negative relationship with work time. Also, Women tended to be more satisfied with time distribution than men. Finally, the satisfaction of spare time was positively related with age, while negatively related to urgency and work time.

This Study aims to find out the planning aspects and detailed techniques in terms of concept of the Ecological Industrial Parks. It consists of the three parts : Firstly, according to theoretical review, this study gives a definition of the concept of ecological industrial parks. Secondly, it institutes planning aspects of ecological industrial parks based on the main concept. Thirdly, 8 case studies show us analysis of detailed techniques used each planning aspects. Ecological industrial parks mean industrial systems which make energy and substance circulated in order to reduce environmental pollutions inside and outside of park like natural ecosystem. To actualize ecological industrial parks, we have to adopt 3 planning aspects which are energy and substance recycling system, environmentally-friendly site planning based on ecology concept, constructing of ecological production and management. In case study, detailed techniques from each planning aspects are shown in table 8. As a result of case study, detailed techniques about planning of energy and substance recycling system is accommodated most. On the other hand, environmentally-friendly site planning techniques based on ecological concept is used passively. And detailed techniques about constructing of ecological production and management are very various as each cases. Finally, in terms of analysis, this study shows us appliable planning when we develop domestic Ecological industrial parks.

Landscape elements of historical and cultural value and elements that have negative impact on landscape due to reckless development teem in rural area. Due to this, local government has established a visual landscape plan. The purpose of this study is to analyze the process and content of domestic rural landscape planning process and to suggest improvements for it. For that, this study measure guideline of Ministry of Agriculture, Food and Rural Affairs against guideline of Ministry of Land, Infrastructure and Transport. To analyze the landscape planning guideline of australia which is similar to domestic rural landscape planning process, and to compare both guidelines. The results of this study are as follow. The stage of landscape resource survey and assessment progressed systematically, but it was not practical because for the lack of survey and assessment method. Therefore, it should be suggested for the survey and assessment technique. The rural landscape plan, established in master planning stage, do not necessarily reflect local government's landscape management on the ground of abstract technic of landscape management. For this sake, to develop evaluation method for development of landscape element seems necessary.
