English term (edited): double-sided dynamic policyholder behavior

首先是"dynamic policyholder behavior"，
根据google的信息，
By dynamic policyholder behaviour (DPB) we mean:
The modelling of assumptions about how policyholders will behave in the future, which are assumed to vary according to one or more
factors which are not known at the outset of an actuarial projection.
Such factors may include, for instance:
Changes to markets (e.g. interest rates, equities);Bonus rates declared by the company, etc.
所以概括起来就是投保人在未来的行为，译为“动态投保人行为”符合意思。

Policyholder 在国内译为投保人，应该比较成熟了，下面的链接是平安保险的保单模板：https://chaoshi.pingan.com/upload/pingancom/2010022211045567...

然后是 double-sided：在网上搜到关于保险的有 " one sided dynamic function 和 "two sided dynamic function"
https://www.soa.org/globalassets/assets/files/research/proje...
这里的 one sided 和 two sided 可以译为单向和双向，function 是函数。


并没有搜到double-sided 的说法，可能指的是 two sided，也可能不是。需要更多上下文参考。

供参考
