easy lingo

Not long ago to do arithmetic modelling of the operation, to use the lingoAnd still have to re-provision the dynamic plan using lingoSo on Baidu found under how to use C + + deployment of lingo, the final result found to be a pitSo I got stuck in it and got two or three cows to figure out that there was a day in the house that didn't sleep ... To bucketHowever, it is clear, but also took a lot of detours, so to write down a little experience, summed u

We sometimes encounter heavy, repetitive work when using lingo, manual operation is obviously time consuming, and the @for function in lingo can only do some simple loops, which requires us to apply the script file to simplify these repetitive work. The English part below is an example from the Official Handbook, which summarizes the 2 points I find useful:1. script file type:. LTF However, the script file

The first step: Enter the target condition and the constraint condition. Each line is separated by semicolons. Then click the Solve button on the toolbar or the Solve submenu under the Lingo menu.Step Two: Check the results in the report.By default, lingo does not perform sensitivity analysis.Need to be configured in lingo to generate a sensitivity analysis repor

with the customer, After the seal is signed, fax will be sent back to the customer. Before sending an instruction to the warehouse and the slitting factory, the type and quantity of required materials were calculated using a fixed formula with a proportional coefficient. for example, if the width of all products required by the customer is If the value is 99, multiply the order by a proportional coefficient greater than 1, or call it magic number. The universal proportional coefficient, such a

Assign values using verbose syntax The logical operators in lingo use the single equal sign "= ". Set Param To Value Put Value Into Param Verbose syntax to assign values more clearly. Case-insensitive Because case-insensitive is case-insensitive, note the comparison of strings. Put"A" = "" -- 1 Case-sensitive Lingo is not sensitive in most cases. Only one case is that the propert

Here we use dynamic planning. And
