Abstract: Abstract We propose a new formulation for the Discrete Ordered Median Problem (DOMP) which has first been introduced in [5]. For this new formulation we present several variable fixing strategies and one family of valid inequalities which are used in a specialized branch & cut procedure. Extensive computational results show that using this method, problems can be solved, which are more than twice as large as those that can be solved by existing solution approaches.
