Abstract

Among shop scheduling problems, job shop and mixed shop are one of the most general models encompassing open shop and flow shop. Many job shop problems are NP hard, but there are numerous cases, which possess polynomial solutions when the number of jobs or the number of machines (or both) is limited.

This thesis gives an overview of methods and algorithms for solving - in polynomial time - such special shop problems, including open, flow, job shop and mixed shop. The tools used include Monge interchange, dynamic programming, greedy techniques and sweep line algorithms and the primary focus of this thesis is to give a taxonomy of such problems with their solutions. Additionally the thesis outlines a neighborhood search technique which uses the disjunctive graph model and which can be applied as a heuristic for a wide range of NP-hard shop problems.
