Import Most Recent（導入最新）按鈕讓應用程序忽略來源導入最新的傳遞函數。
左下角的下拉菜單列表用于根據需要導入變量選擇導入描述的具體行為。
Ignore Descriptions（忽略描述） 不導入描述。
Import Descriptions（導入描述） 當在預先存在模型里描述為空時選擇導入描述。
Overwrite Descriptions（覆蓋描述） 始終導入描述，若有需要將覆蓋預先存在模型的描述。
單擊Finish按鈕后，將顯示導入過程狀態。如果成功完成導入過程，對話框顯示消息“Import Complete. Do you wish to see the import log?（導入完成，你是否希望查看導入日志？）”。單擊Yes按鈕顯示導入日志文件，否則單擊No繼續。
如果你選擇顯示日志文件，包含在AIDAPro文件中的每個選中導入輸入輸出傳遞函數都將得到顯示。若在導入過程中遇到任何問題，他們也會顯示。
導入過程完成后，用戶可以使用圖形模型構建器方便地工作。可用選項包括：
?編譯 - 提供模型檢查和編譯，即不可測量擾動的輸入以及適合仿真生產的模型展示。
?曲線 - 顯示了模型輸入到輸出動態的脈沖/階躍響應曲線。
?分析 - 介紹了模型的操作和測量干擾輸入與模型輸出之間的增益矩陣。
?報告 – 詳細描述了模型傳遞函數的類型，參數及相應的連接，使得生成的報告足以重新繪制整個模型。
在模型搭建時使用變換
工廠本身是非線性的。然而在許多情況下，工廠可以在其操作點根據合適的變換線性化。例如，對輸入和輸出變量使用對數變換可使得在轉換坐標后工廠行為變為線性。在僅作輸入變換的情況下（下圖的輸入變換），MVs/DVs都是變換后的坐標，SMOCPro中標識的模型的POV都是工程單位，而MV/DV是變換后坐標。在當前輸入和輸出都作變換的情況下（下圖的輸入—輸出變換），SMOCPro中辨識模型的POV和MV/DV都處于變換坐標下。
為進行轉換，SMOCPro提供了一個工具選擇分段線性變換（查找表）。當輸入在范圍內時，變換將在兩個連續點之間進行線性內插，當輸入在范圍外時，變換將進行最后兩個點的外推。從理論上說，如果點的數目足夠大，分段線性變換可以模仿任何函數。

The Import Most Recent button lets the application import the most recent transfer functions regardless of their origin.
The drop-down menu list at the bottom left hand corner is used to choose specific actions for importing the descriptions of the variables to be imported.
Ignore Descriptions Do not import descriptions.
Import Descriptions Import descriptions when the descriptions in the pre-existing model are empty.
Overwrite Descriptions Always import descriptions anyway, overwriting the pre-existing description when necessary.
After clicking on the Finish button, the import process status is displayed. If the import process finished successfully, a dialog box displays the message “Import Complete. Do you wish to see the import log?” click the Yes button to display the Import Log file, otherwise click No to continue.
If you have chosen to display the log file, all the input-to-output transfer functions contained in each of the AIDAPro files selected-for-import are displayed. If there were any problems encountered during the import process, they are also displayed.
After the import process has been completed, the user can easily work with the model using the graphical model builder. The available options include:
?Compile – Provides model checking and compilation, i.e. incorporation of unmeasured disturbance inputs and production of the model representation suited for simulation.
? Plot – Shows the impulse/step response plots of the model input-to-output dynamics.
? Analysis – Presents the gain matrix between the model’s manipulated and measured disturbance inputs, and the model’s outputs.
? Report – Details the model’s transfer functions types, their parameters and the corresponding connections so that the resulting report is sufficient to re-draw the whole model at once.
Using transforms for model building
Plants are inherently nonlinear. However, in many cases, the plant can be linearized about its operating point by a suitable transform. For example, a logarithmic transform can be applied to the input and output variables such that in the transformed coordinates the plant behavior is linear. In the case of only input transform (Figure Input Transfer below), the MVs/DVs are in the transformed coordinates and the identified model in SMOCPro is between the POV in Engineering Units and the MV/DV in Transformed coordinates. In case where both input and output transforms are present (Figure Input-Output Transform below), the identified model in SMOCPro is between the POV in Transformed coordinates and the MV/DV also in Transformed coordinates.
To carry out the transforms, SMOCPro provides a tool with the option of piecewise linear transform (lookup table). This transform linearly interpolates between two consecutive points when the input is in the range or linearly extrapolates the last two points when the input is out of the range. Theoretically, piecewise linear transform can mimic any function if the number of the points is sufficiently large.
