In this paper, we develop a method called the resource-dependent critical path method (RDCPM) to identify resource dependencies that exist between activities in order to determine the critical paths and real floats in resource-constrained scheduling (RCS) techniques. The popular critical path method (CPM) and program evaluation and review technique (PERT) network techniques are based on the assumption of unlimited resources. This assumption is not valid in most practical applications, wherein exist definite limits on the amount of available resources. Although RCS techniques can consider resource limitations, they do not provide the correct floats and critical path, as do the CPM and PERT techniques. This is because in addition to technological relationships, a resource constraint schedule contains resource dependencies between activities that are neglected in RCS techniques. RDCPM provides reasonable resource links between activities so that both total floats and free floats can be computed accurately, and critical activities and critical sequences can be correctly identified. Moreover, to minimize the number of resource links and reduce the complexity of the network, RDCPM establishes resource links between activities while considering their optimization and removes redundant relations. This approach makes a schedule more realistic and provides a stable schedule with progress updates. Therefore, it should be considerably more beneficial and useful for the construction industry.
東日本大震災の震災復興は，二年が経過しても目に見えて進まない．未曾有の大地震と津波が直接的な原因ではあるが，これまでの大規模地震災害への対策は内陸型地震への対策が主体であり，臨海型地震による広域への津波災害に対し，これまでの経験が生かせなかったことがその原因である．加えて基礎自治体や中央政府の復興へのシステム自体にも原因があると考えられる．基礎自治体には広域大規模災害への事前の備えがなく，中央政府では平時のシステムや法規制により対処したことが復旧・復興の遅れを生んだ．本論文では，基礎自治体が地域の実態に則した効果的な施策を実行する“Local Public Management”の観点から，迅速な復興へ向けての組織と法規制の在り方の課題を整理し，事前の対策から復興に至る一連の災害マネジメントシステムの必要性を見出した．
On 7 of July 2008, the sacred Site of Preah Vihear was inscribed into the list of World Heritage. Preah Vihear province is one of the least inhabited compared to other regions, and is one of the most undeveloped regions in Cambodia. In this paper, the authors discuss the past development trend, present issues to develop, in order for the future sustainable development of the valuable heritage region. Since the area has the potential for agriculture production, the long term vision as well as the development policy should be established for the success of sustainable development for the overcome of the poverty.
