Flexible flow shop (or a hybrid flow shop) scheduling problem is an extension of classical flow shop scheduling problem. In a simple flow shop configuration, a job having ‘g’ operations is performed on ‘g’ operation centres (stages) with each stage having only one machine. If any stage contains more than one machine for providing alternate processing facility, then the problem...

Genetic algorithms are a very popular heuristic which have been successfully applied to many optimization problems within the last 30 years. In this chapter, we give a survey on some genetic algorithms for shop scheduling problems. In a shop scheduling problem, a set of jobs has to be processed on a set of machines such that a specific optimization criterion is satisfied. According to the restr...

The distributed blocking flow shop scheduling problem (DBFSP) allows modeling the scheduling process in companies with more than one factory. It configures production systems as flow shop lines where the blocking constraint must be considered. To the best of our knowledge, this variant of the distributed permutation flow shop scheduling problem has not been studied. In this working paper, we sh...

Flow shop scheduling is a type of where sequence follows for each job on set machines processing. In practice, jobs in flow shops can arrive at irregular times, and the no-wait constraint allows changes order to flexibly manage such irregularity. The flexible problems with have mainly addressed optimization floor manufacturing, processing, allied industries. scope this paper identify literature...

A no-wait robotic cell is an automated ow shop in which a robot is used to move the parts from a machine to the next. Parts are not allowed to wait. We analyze the complexity of the part sequencing problem in a robotic cell with three machines, for di erent periodical patterns of robot moves, when the objective is productivity maximization. c © 2000 Elsevier Science B.V.

Flexible flow shop scheduling problem (also called blended flow shop scheduling problem) is a sort of complex Job Shop Scheduling problem. For the Flexible Flow Shop scheduling problem, only in very special cases, there are polynomial optimal algorithms. In most of the other cases, the problems are NP-Hard. It is a simplification of the original problem to solve Flexible flow shop scheduling wi...

This study considers the production of chemotherapy drugs for cancer treatment. An important factor determining quality service treatment is time patient must wait to receive his or her injection drug. Chemotherapy and delivery are modeled as a scheduling problem combined with vehicle routing problem. The three-stage hybrid flow shop problem, variant multi-trip due dates. objective function min...
