This paper is concerned with detailed scheduling of job-shop like manufacturing systems. It addresses the scheduling of jobs, either simple, requiring the manufacture of a batch of parts, i.e. simple products, or complex, comprehending the parts fabrication and their multistage assembly into a batch of products. The Product-oriented Scheduling approach was adopted, assuming that full scheduling...

Scheduling optimization of manufacturing processes becomes more and more important. Complex models with a lot of constraints cause a higher computational effort of the simulation. Optimization cycles of heuristic optimization algorithms like genetic algorithms or local search strategies can easily be scheduled in parallel. But recurrent requirements are the distribution of the model, the interc...

Knowledge based or Intelligent Control of Flexible Manufacturing Systems (FMS) means a continuous or frequent observation and evaluation of the status and condition of the system performance, decision making based on the evaluation results and on pre-defined knowledge, and then the operation according to the decisions. This kind of process is applied if any kind of disturbance or irregularity h...

The paper presents a software package developed for the integration of a Flexible Manufacturing System (FMS) with the CAD department. The software package is able to make the informational link between a CAD system, a CAM program and the control system of CNC machines (file transfer and translation).

The scheduling problem for ̄exible manufacturing systems (FMSs) has been attempted in this paper using the ant colony optimization (ACO) technique. Since the operation of a job in FMSs can be performed on more than one machine, the scheduling of the FMS is considered as a computationally hard problem. Ant algorithms are based on the foraging behaviour of real ants. The article deals with the an...

 This paper considers a bi-objective scheduling problem in a flexible manufacturing cell (FMC) which minimizes the maximum completion time (i.e., makespan) and maximum tardiness simultaneously. A new mathematical model is considered to reflect all aspect of the manufacturing cell. This type of scheduling problem is known to be NP-hard. To cope with the complexity of such a hard problem, a genet...

This paper describes the development of an agent-based framework for the intelligent control of flexible manufacturing systems. An FMS is a complex manufacturing system, in which the control system is responsible for the planning, control and monitoring functions. Traditionally, manufacturing systems are commonly established with hierarchical control architecture. This approach is not flexible ...

reflect the temporal relationships between manufacturing activities and the capacity limitations of a set of shared resources. The allocation also affects a schedule's opti-mality with respect to criteria such as cost, lateness, or throughput. The globalization of manufacturing makes such optimization increasingly important. To survive in this competitive market, manufacturing enterprises must ...

Flexible Manufacturing Systems (FMS) are essential for small/medium batch and job shop manufacturing. These types of production systems are used to manufacture a considerable variety of products with medium/small production volumes. Therefore, the manufacturing platforms supporting these types of production must be flexible and organized in Flexible Manufacturing Cells (FMC). Programming FMC's ...

Customer ordering behaviorin the form of size and timing of orders are critical for manufacturing systems such as make-to-order or assemble-to-order systems. To be competitive a Make-to-order manufacture must be flexible, both with regards to volume and product mix. A particularly critical parameter in determining the flexibility needs in the case of responsive manufacturing environments is the...
