这段代码并不是 Lingo 语言，而是 AMPL 语言。你需要使用 AMPL 软件来运行这段代码，而不是 Lingo。

如果你已经在 AMPL 中运行了这段代码，但是无法输出结果，可能是因为缺少输出语句。你可以在 Minimize 语句后面添加一个 print 语句，例如：

Minimize Total_Cost : = @sum((i, j, k | k <> j), X(i,j,k) * COST_MATRIX(i,j));
print Total_Cost;

这样就可以输出最小化总成本的结果了。同样地，你也可以在 Subject to 语句后面添加 print 语句，输出约束条件的结果。

以下是对代码进行的一些修改：

1. 在Sets部分，将row1改为CUST，将row2改为CENTER，使得集合名称更直观。

2. 在Variables部分，将变量Y的类型改为Integer，使得变量Y只能取0或1两个值。

3. 在Minimize部分，将目标函数中的不等式符号“~=”改为“<>”，表示不等于。

4. 在Constraint1部分，添加了一个新的参数CAPACITY(i)，表示第i个客户所需的货物容量。

5. 在Constraint2部分，将约束条件改为大于等于1，保证每个中心至少分配给一个客户。

修改后的代码如下：

根据提供的引用内容，这是一个关于AirtestIDE的问题。根据引用\[1\]，如果遇到旧版本使用没问题，但更新后出现问题的情况，需要提供详细的信息来进行问题解答。具体需要提供旧版本信息（IDE版本，是否使用本地python环境，若使用本地安装的airtest和pocoui版本如何）、新版本信息（IDE版本，是否使用本地python环境，若使用本地安装的airtest和pocoui版本如何）、进行了怎样的操作/运行了怎样的代码、旧版表现如何，新版表现如何（如出现报错，请提供完整的报错信息）。

根据引用\[2\]，如果需要将本地Python环境的库更新至与1.2.14一样的环境，可以使用如下命令进行更新：

# airtest最新版为1.2.6
pip install -U airtest
# pocoui最新版为1.0.87
pip install -U pocoui

根据引用\[3\]，在进行覆盖更新之前，请检查是否将脚本保存到了AirtestIDE的文件路径内，如果有，请备份脚本后再进行覆盖更新，否则进行覆盖更新操作后也会覆盖掉保存在AirtestIDE路径下的脚本。

根据提供的报错信息，可以看到出现了一个AdbError异常。这个异常是由airtest.core.android.adb模块的shell函数引发的。具体的错误信息是stdout和stderr的内容，其中包含了一些Permission denied的提示。根据这个错误信息，可能是由于权限问题导致的。建议检查相关的权限设置，确保有足够的权限来执行相应的操作。

请提供更多详细的信息，以便更准确地解决问题。
