An increasing number of firms are marching to the drumbeat of business process redesign (BPR), alternatively called reengineering. The term reengineering may be new, but the idea of process redesign is familiar to most engineers involved in logistics and production control. Just-in-time (JIT), Total Quality Management (TQM), Flexible Manufacturing Systems (FMS), Computer Integrated Manufacturin...
Mass customization manufacturing (MCM) has been gaining recognition as an industrial revolution in the 21st century. This paper presents innovative approaches in realizing and exercising MCM in theoretical and practical applications. Strategies of generalized production line platform and modularization are explored to support dynamic reconfigurations of MCM. NIST’s XML-based Shop Data informati...
This paper presents a novel scheduling of resource-constrained Flexible Manufacturing System (FMS) with consideration the following sub-problems: (i) machine loading and unloading, (ii) manufacturing operation scheduling, (iii) assignment, (iv) Automated Guided Vehicle (AGV) scheduling. In proposed model, both AGV machinery are considered as required resources. Energy efficiency AGVs has been s...
On time replacement of a cutting tool with a new one is an important task in Flexible Manufacturing Systems (FMS). A fuzzy logic-based approach was used in the present study to predict and simulate the tool wear progress in turning operation. Cutting parameters and cutting forces were considered as the input and the wear rate was regarded as the output data in the fuzzy logic for construct...
A common way of dynamically scheduling jobs in a flexible manufacturing system (FMS) is by means of dispatching rules. The problem of this method is that the performance of these rules depends on the state the system is in at each moment, and no single rule exists that is better than the rest in all the possible states that the system may be in. It would therefore be interesting to use the most...
Modeling of Holonic Manufacturing Control Systems Considering Reconfiguration and Timing Constraints
Automation and control systems(ACSs) must ensure the fulfillment of the current requirements in manufacturing systems, such as flexibility, distributed architecture, and agility in response to changes imposed by the market or the inevitable occurrence of faults. In this context, one solution to design ACSs is a combination of techniques such as holonic control system (HCS) and active fault-tole...
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 ...
In the modeling and control of manufacturing systems one of the aims is to obtain a system that can run in an automatic way. This means that the software in charge of the monitoring and control of the system must be able to deal with a set of problematic situations (system failures, system deadlocks, overrow of storing facilities, etc.). In this paper we are going to concentrate on one of the p...
Rapid prototyping of complex systems and their control strategies is an important approach in system modeling. Naturally, these systems can be seen as a network of concurrently running communicating objects. One application eld are exible manufacturing systems (FMS) used in computer integrated manufacturing (CIM). A FMS consists of concurrently working machines which are connected by a computer...
FMS’s is indeed a very promising technology as they provide flexibility, which is essential for many manufacturing companies. FMS can yield a number of dissimilar jobs simultaneously. Each part requires different operations in a certain sequence and workstations can typically perform a variety of operations. A point to be noted here is each variety would be with low volume of production. This p...
