Chmiel's model [Chmiel 2000] is a generalization of these cost models. This model is different from others in that the decisions are composed of four levels and treats reuse projects from a point of view of long term run. Each level corresponds one engineering cycle. Each level is a decision making process based on calculation of NPV, ROI, and other economic indices. Reuse investment decisions are made on different levels from the corporate to the programming. Chmiel's model doesn't cover Commercial-Off-The-Shelf (COTS), Product Line Engineering (PLE) and benefits due to shortened Time-To-Market (TTM) and can only deal with internal traffic since the model assumes all of the reusable components are built from scratch in house. For example, Extra efforts caused by the use of COTS, assessment, tailoring, glue code and COTS volatility, are not covered in this model. And this model doesn't treat the benefits of TTM, for example, business performance. By extending Chmiel's model, the new model is applied to CBSE (Component-Based Software Engineering), COTS reuse systems and PLE. In addition, attempts of quantifying benefits of shortened TTM are made within this study and a TTM submodel is developed to cover this issue. This study also addresses the issue to analyze and optimize corporate Return On Investment (ROI). The rational is that optimizing (maximizing) the corporate ROI under the condition that all other ROI's are positive. By designing an algorithm and applying it to the data, this study discovers the method how to make the maximized value of corporate ROI. And this model is supported through a tool based on the model rationale. Users to this tool are corporate management and development engineers. The supporting tool has user-friendly interface and allows users to input values of related parameters. A detailed report is produced, which is composed of details about costs and benefits, final Net Present Value (NPV) and ROI of each cycle.","PeriodicalId":17543,"journal":{"name":"Journal of Zhengzhou University","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2005-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87278708","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
