A flow line is a conventional manufacturing system where all jobs must be processed on all machines with the same operation sequence. Line buffers allow non-permutation flowshop scheduling (NPFS) and job sequences to be changed on different machines. A mixed-integer linear programming model for non-permutation flowshop scheduling and the buffer requirement along with manufacturing implication i...

in this paper, the flexible job shop scheduling problem with machine flexibility and controllable process times is studied. the main idea is that the processing times of operations may be controlled by consumptions of additional resources. the purpose of this paper to find the best trade-off between processing cost and delay cost in order to minimize the total costs. the proposed model, flexibl...

Changes in equipment and production demand cannot be predicted at the design stage. Therefore, decision taking mechanisms must rely on real time information collected from the shop floor. To perform scheduling and routing optimization, not only modifications in values of parameters of interest, but also in the flow itself must be accounted for. This paper addresses this problem and proposes a m...

“Planning and Scheduling in Manufacturing and Services” written by Michael L. Pinedo and published in the Springer Series in Operations Research is a recent book intended for a senior level or master level course on planning and scheduling either in an engineering or a business school. The book consists of four parts. Part I introduces the main features of scheduling models in manufacturing and...

The first comprehensive survey paper on scheduling problems with separate setup times or costs was conducted by Allahverdi et al. (1999), who reviewed the literature since the mid-1960s. Since the appearance of that survey paper, there has been an increasing interest in scheduling problems with setup times (costs) with an average of more than 40 papers per year being added to the literature. Th...
