    29. 

  29. 1、平台中存在不同级别“业务主体对象”的设置，在设置项相同的情况下，如技师对某个开通项目的某个设置、技师对自己全局的设置、店铺的设置、代理的设置、平台的设置，设置优先级从大到小，如果找不到这个设置项则往上找，直到找到平台配置的默认设置项。
    30. 

  30. 2、如果设置的权限开放给不同级别的“业务主体对象”，则需要平台来限制每一个设置项的可调整范围，这个又该怎么设计？
    31. 

  31. 3、这个设置功能需要设计一个模块，按 io 模型分析，输入参数可能是业务主体对象 id，返回正确的设置集（如下单相关设置、接单相关设置、分账相关设置等）
