建築プロジェクトにおける工事編成最適化: 工事編成支援システムの提案

A single construction project is undertaken by a multitude of firms comprised of a prime contractor and many subcontractors. Generally, these organizations are assembled only for the period of the construction project. The success of the project depends largely on whether subcontractor organizations can be properly engaged and managed. The general contractor has the right to define the work scope for each component of the construction project and to assign the subcontractor to carry out each subtask. Therefore, it is very important for the general contractor to develop a good subcontractor team based on the specific characteristics of each project. In this paper, we present a new concept of a sub-package problem by focusing on its management time and cost. Also, we formulate the sub-package problem as a mathematical programming model through which we demonstrate some numerical results.
