Due to the reduction in public investment for construction projects and the introduction of a new bidding system for public entities, and while competition for orders is getting fiercer by the year, there is a great need for construction companies to make strategic business decisions based on an objective assessment of their company's strengths and weaknesses. To that end, the strategic use of information technology (IT) is an effective means, and it is essential that information important to the operation of the company be in/output and analyzed flexibly and promptly. However, business applications developed through the method currently in use are oftentimes unable to handle constantly changing user requirements. From consultations with a number of general contractors, we have learned that the data management requirements for the highest priority business tasks are:
1. intermixing of files with different attributes
2. flexible decisions, additions, and changes to data analysis items
3. data searches that accommodate variances in transcription
4. data-centered analysis that does not depend on the analyst's experience
5. input/output of multiple attributes for each data file
To satisfy the six user requirements above, our research has developed a general-purpose data management system employing the Cellular Data System, a flexible system of data processing.
建設工事への公共投資の減少、公共工事の総合評価方式導入に伴い、競争が年々激しくなっている。そんな中、建設企業は戦略的に自社の強み弱みの認識に基づき意思決定を行う必要がある。そのためには情報技術の戦略的活用は非常に有効であり、経営判断を行う上で重要な情報が入出力され、柔軟かつ迅速に分析されねばならない。しかしながら、既存の技術を利用した業務システムはユーザー要求の変化にすぐには対応できない。総合建設業へのヒリング調査から、データ管理に対する再優先の要求課題は以下であることがわかった。 1.異なる属性のファイルの混在
