Activity form using input and output criteria, but no gateways, is more suitable for simplifying visualization of the process model by hiding the branching logic in the input and output criteria.

活动形式使用输入和输出条件，但不使用网关。它将分支逻辑隐藏在输入和输出条件中，因而更适于简化流程模型的可视化形式。

Second, the input-output model assumes fixed relationships over the time of the forecast horizon.

The model begins with an input-output table, which says that, for example, the steel mill industry uses the output of the iron ore industry, the electric utility industry, as well as labor and some lesser inputs.
