Constraint Propagation in Flexible Manufacturing by Toan Phan Huy

By Toan Phan Huy

This e-book offers an intensive research of scheduling difficulties that come up in a versatile production atmosphere with scarce source provide. Generalizations of the well-known activity store scheduling challenge are mentioned. As a uncomplicated and customary strategy for fixing those difficulties constraint propagation is utilized in numerous answer equipment. The effectiveness of constraint propagation is validated by means of the answer of a excessive variety of benchmark challenge circumstances.

Implementation is baseq' on the one described in [RND77]. The second problem requires more consideration. From a theoretic point of view, generating a maximal clique decomposition yields more information, since this completely captures the clique structure of a disjunctive graph. In practice, however, generating too many cliques is not sensible, because the possible gain of information is outweighed by the computational complexity of examining the cliques and deducing this additional information.

4. LOCAL SEARCH 29 Diversity and Connectivity The neighbourhood structure should consider diversified moves which cover a wide area of the solution space. In this context, connected neighbourhood structures are the most desirable. A neighbourhood is connected if starting from any solution, there exists a finite sequence of moves leading to a globally optimal solution [LAL88]. Note that connectivity does not require these moves to be actually carried out. Size The size of the neighbourhood should be within reasonable limits.

The length of the longest path in gs (P) is the makespan of ST( B). We denote with C*(S) the makespan of ST(S) and say that S is optimal if ST(S) is optimal. 1. 2. Given the processing times (Pl, ... ,PlO) = (1,2,3,4,5,6,7,8,9,10), the associated earliest start time schedule ST(S) is with the makespan C*(S) = 40. o 40 CHAPTER 3. 2: A complete selection. Inversely, each schedule can be transformed into a complete and acyclic selection. 2 (Schedule Selections) LetP = (O,C,D,P) be an instance of the DSP, g(P) the associated disjunctive graph and ST = (st l , ...
