国家提出要建设一个针对特定灾害的防灾预警系统，以减少灾害损失。共有三个互斥的建设方案，寿命期均为20年。根据统计资料分析及专家论证，如果不建造该预警系统，预期未来每年灾害经济损失为120亿元；如果建造该防灾预警系统，除需要初始投资外，每年还需要支付系统维护费用，但可降低每年预期灾害损失。各方案的初始投资、每年运营维护费用及预期年损失等资料见表4-95。设定基准收益率为8%。复利系数见表4-96所示。

问题
项目财务评价人员拟采用费用年值比较法来评价三个方案的优劣，请判断该方法是否恰当，为什么
参考答案：费用年值比较法适用于效益相同或基本相同，又难于具体估算效益的方案进行比较的情况，而本题中三个方案的效益显然不同，所以不宜采用该方法。
