| Summary:
|
$(\max ,+)$-linear functions are functions which can be expressed as the maximum of a finite number of linear functions of one variable having the form $f(x_1, \dots , x_h) = \max _j(a_j+ x_j)$, where $a_j$, $j = 1, \dots , h$, are real numbers. Similarly $(\min ,+)$-linear functions are defined. We will consider optimization problems in which the set of feasible solutions is the solution set of a finite inequality system, where the inequalities have $(\max ,+)$-linear functions of variables $x$ on one side and $(\min ,+)$-linear functions of variables $y$ on the other side. Such systems can be applied e.g. to operations research problems in which we need to coordinate or synchronize release and completion times of operations or departure and arrival times of passengers. A motivation example is presented and the proposed solution method is demonstrated on a small numerical example. (English) |
