In this paper, the m-machine no-wait flowshop scheduling problem with sequence-dependent setup times is considered to minimize the makespan. According to the problem characteristics, the increment properties of some fundamental operators of algorithms are analyzed. Two increment-based methods FSP (fittest swap points) and FMP (fittest move points) are constructed for fast evaluation on all algorithms...
No-wait flowshops with flowtime minimization are typical NP-complete combinatorial optimization problems, widely existing in practical manufacturing systems. Different from traditional methods by which objective of a new schedule being completely computed objective increment methods are presented in this paper by which the objective of an offspring being obtained just by objective increments and computational...
In this paper, no-wait flow shop scheduling problem with total flowtime minimization is considered. A hybrid heuristic is proposed, which is based on PHI (p) (presented by Aldowaisan and Allahverdi, OMEGA, 2004). A composite algorithm is adopted to generate the initial seed. Job insertion in PHI (p) is replaced with an existing constructive heuristic. Experimental results show that the proposal outperforms...
