Abstract

In the process of selecting commercial off-the-shelf (COTS) products, it is inevitable to encounter mismatches between COTS products and system requirements. Mismatches occur when COTS attributes do not exactly match our requirements. Many of these mismatches are resolved after selecting a COTS product in order to improve its fitness with the requirements. This paper proposes a decision support approach that aims at addressing COTS mismatches during and after the selection process. Our approach can be integrated with existing COTS selection methods at two stages: (I) When evaluating COTS candidates: our approach is used to estimate the anticipated fitness of the candidates if their mismatches are resolved. This helps to base our COTS selection decisions on the fitness that the COTS candidates will eventually have if selected. (2) After selecting a COTS product: the approach suggests alternative plans for resolving the most appropriate mismatches using suitable actions, such that the most important risk, technical, and resource constraints are met. A case study from the e-services domain is used to illustrate the method and to discuss its added value

处理COTS产品与系统需求不匹配的决策支持

在选择商用现货产品的过程中，不可避免地会遇到商用现货产品与系统需求不匹配的问题。当COTS属性与我们的需求不完全匹配时，就会出现不匹配。在选择COTS产品之后，为了提高其对需求的适应性，许多这些不匹配都得到了解决。本文提出了一种决策支持方法，旨在解决在选择过程中和之后的COTS不匹配问题。我们的方法可以在两个阶段与现有的COTS选择方法相结合:(1)在评估候选COTS时:如果候选COTS的不匹配得到解决，我们的方法可以用来估计候选COTS的预期适应度。这有助于将COTS选择决策建立在COTS候选者最终将拥有的适合度的基础上。(2)在选择了COTS产品之后:该方法建议使用合适的行动来解决最合适的不匹配的替代计划，从而满足最重要的风险、技术和资源约束。本文用电子服务领域的一个案例来说明该方法并讨论其附加价值
