On complexity of bilevel problems of location and pricing

Abstract:
We study omplexity of bilevel problems with different pricing strategies: uniform, mill and discriminatory. It is shown that these problems are NP-hard in the strong sense, belong to Poly-APX class and are complete in its relative AP-reducibility.
Bibliogr. 17.

Keywords: bilevel problem, location, pricing, computational and approximation complexity, NP-hard in the strong sense, AP-reducibility, Poly-APX-completeness.
