In recent years more attention has been devoted to the computer aided scheduling problems in industries process. Computer programs are now available in order for production engineers to develop an understanding for how a decision can be taken while making the scheduling process easier to determine when, where and how to produce a set of products. Due to the discrete decisions involved, these scheduling problems have a combinatorial nature and are therefore challenging from a computational complexity standpoint. With the tools, scheduling studies can be run to simulate present industry conditions and to help with the long-range planning of new facilities for a given production plan. The tools also provide an opportunity for the production engineers to do such things as optimise the production process and apply diverse mathematical optimisation techniques.
