| To the Students
The (solved) problems below comprise: original research questions of mine;
and academic exercises. All are freely accessible,
but it is the exercises that are meant for student practice.
Our style (since 1998) is similar to Prof. Ponce's
(since 2000, in Hydraulics), and I know no other similar web sites.
These exercise problems provide answers to various topics mainly in "Operational Research" and "(Statistical) Quality Control". This material was conceived to be used with my support, in classes, not just as self-study. So, some cases are not easy to understand. I am available to resolve any doubt (here) . I suggest that the students also solve any problem by themselves, namely by programming in their preferred language. I invite the interested students to contact me, so that we may produce further scientific work, to be published, if possible. | ||
