Welcome to the second unit of the introduction sequence to mathematical programming. We suggest you watch a video<\/strong> of the theoretical contents and download the slideshow<\/strong> of the lesson thanks to the corresponding links. You may then do one or several activities for each lesson. The model construction activities<\/strong> may use models already developed in a previous unit. If you have not done the activity in question, you may find the relevant model<\/strong> in the \u201cModel library<\/strong>\u201d<\/a>.<\/p>\n

In this unit, you will find \u201cAdditional activities<\/strong>\u201d to do in order to reinforce your skills.<\/p>\n\n\n<\/colgroup>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
