1.1 Introduction To succeed in today’s trends of manufacturing environments, manufactures have to modify their operations to obtain a better and faster response with the continuous changing market demands. Flexible Manufacturing System emerged as a powerful tool one due to its large flexibility, which is essential to stay competitive in this highly excellent environment. Flexible Manufacturing System is a complex system consisting components like machine equipment tool, material handling system (AGV), storage and retrieval system. Flexible Manufacturing System scheduling problems are more complex, since the jobs are highly interrelated and in addition have multiple job types and alternative routings. Accordingly, an FMS is designed to produce …show more content…
FMS is a system that consists of numerous automated machine tools connected by an automated material handling system. Shorter lead times, meeting demand fluctuations, handling volume and variety, reduction in space and people and obtaining better control due to automation as in Fig. 1(a). FMS is larger than the flexible manufacturing cell, not only in the no. of workstations and floor area it may contain, but also in the number of supporting stations and equipment in the system, such as part/pallet washing stations, co-ordinate measuring machine equipments, storage stations and so on. Computer control system is also more sophisticated; this type of functions not found in the flexible manufacturing cell such as diagnostics and tool monitoring during the machining operations. The main disadvantage is that the initial installing cost and operational costs are high and it is necessary to have enough volumes to justify the use of …show more content…
The central control computer system which controls material movements and machine flow. The generation of each part or work – piece will oblige an alternate mix of assembling hubs. Development of parts starting with one hub then onto the next is done through the material handling system (MHS). Onward the end of part preparing, the finished parts will be steered to an automatic inspection hub, and in this manner emptied from the Flexible Manufacturing System. In the present business situation the competitiveness of any the aggressiveness of any assembling industry is controlled by its capacity to react rapidly to the quickly changing business and to create the great items easily. Essential objective of any manufacturing industry to accomplished the high level of throughput, ability to respond efficiently according to the changing demands of the consumers. System utilization computed as a percentage of the available times (number of the machines accessible for generation reproduced by the quantity of changing so as to work hours), it can be increased by changing in plant layout, by diminishing exchange time between two stations and throughput, defined as the number of parts delivered by the last machine of a manufacturing system over a given duration of time; Groover, M. P., (2008)
In today’s operational management arena, there are certain expectations from a managerial aspect that must be met in order to be successful. A comprehensive look at the Space Age Furniture Company will show exactly what the Materials Requirement Planning (MRP) calculations are for this company at present time and then take the information given in order to properly suggest ways to improve the sub-assemblies. In addition, there will be an analysis on the trade-offs between the overtime and inventory costs. A calculation will be made on the new MRP that will improve the base MRP. This paper will also compare and contrast the types of production processing to include the job shop, batch, repetitive, or continuous, and determine which the primary mode of operation should be and exactly why. A detailed description on how management can keep track of the job status and location during production will also be addressed. Finally, there will be a recommendation on they type of changes that need to occur that will be beneficial to the company and at the same time add value to the customer. This paper will conclude with summary of the major points.
For an assembly plant to be so productive materials must be on hand at all times. Every mustang begins with a truck; reels of raw steel weighing in at 30 tons a piece are delivered periodically. Now this raw steel is the moved to a machine that cuts i...
Any company is unable to manufacture a 100%. Therefore, people should really focus on the constraints, in a way that it will prevent a failure that will damage the entire system. Bottlenecks are the key in every plant, because it will determine the activity that will create a profit and maximize the business output.
Hybrid manufacturing systems combine CNC milling with additive manufacturing to fully tap on the benefits each method can offer. The end result is an all-in-one machine that is capable to produce final products with complex features quickly and efficiently.

It is also necessary to take into account the consequent restrictions of the manufacturing process. This means that the firewall and seat geometry needs to be designed considering the characteristics and limitations of the 5D CNC milling machine (used to obtain the milling models) and the Mould.
Any production line involves some form of inspection; the most basic form is manual visual inspection. This kind of inspection is not always the least expensive or the most reliable. For example, metal sheets are monitored visually by trained personnel, which require a very slow production line for reliable detection and to insure the inspector’s safety. Such systems are very costly due to the slower production speed; they are also labor intensive and labor dependent and need to be a separate stage to avoid production line interruptions. Thus a less expensive more reliable automated system is needed.
So it’s important to research the product and the vendor to make certain that you select the right system for your business. You’ve got to have a system that fully integrates all aspects of running your manufacturing business, offers advanced features and options but is intuitive and easy to use so employees can grasp hold quickly, and adapts to the way you do business rather than forcing you to adapt to the software.

The development of the manufacturing industry, quality and control, manufacturing capacity increase or the duration and the need to reduce cost has arisen is inevitable. Thus automation and programming concepts were started years ago. Automation is a machine's operative procedures and their sequence start form beginnig to end without human intervention, and its done automatically. Programming of the sequence of operations is prerared and tranfered to the counter. A bench during the operation of the program, and in the process, this will provide for amendments to the alignment and speed, then the counter is called flexibility.
Material handling system is an important equipment and in the design of an effective manufacturing design. One of the main tasks in material handling system design is the selection and setup involving apparatus, demanding comprehensive technical understanding along with methodical research. Material handling equipment selection is a very complex and tedious task. The main factors contributing to the complexity of the equipment selection problem is the constraints imposed by the facility and materials, a variety of disagreeing design and style requirements, anxiety inside functional environment, and some of equipment varieties in addition to designs accessible. In recent years, the equipment selection
This is the activity carried out by organizations that own production sites, and their performance has a major impact on product cost, quality, speed of delivery and delivery reliability, and flexibility [8]. As it is quite an important part of the supply chain, production needs to be measured and continuously improved. Suitable metrics for the production level are as follows. Order lead-time, the total order cycle time, called order to delivery cycle time, refers to the time elapsed in between the receipt of customer order until the delivery of finished goods to the customer. The reduction in order cycle time leads to reduction in supply chain response time, and as such is an important performance measure and source of competitive advantage [9]. It directly interacts with customer service in determining competitiveness. Range of product and services: According to [8] a plant that manufactures a broad product range is likely to introduce new products more slowly than plants with a narrow product range. Plants that can manufacture a wide range of products are likely to perform less well in the areas of value added per employee, speed and delivery reliability. This clearly suggests that product range affects supply chain performance. Effectiveness of scheduling techniques is another important measure of supply chain effectiveness. Scheduling refers to the time or date on or by which
Toyota has implemented many different systems such as performance monitoring software, the Just in time (JIT) inventory system, electronic quality control system, communication system and information system thought out their value chain which enable to make correct decision during the manufacturing process. They have identified that having large inventories of spares cost them extensive capital and they have implemented the Just in time (JIT) inventory system which advices the suppliers the exact spares that the product line required and provides a time frame. Toyota adopted continuous learning and embraces change allowing their staff to research and innovation (Toyota
Digital fabrication is coming into the construction industry to create precisely crafted and complex buildings in response to the new competitive environment and construction market demands. Thanks to advanced technology, the good revolution can be seen in most industrial activities. Almost all of the industry sectors are trying to keep themselves up to date with new related innovation to boost their sustainable growth. However, unfortunately architects and construction engineers have been more conservative despite all of the massive global investment in the construction sector. This conservative trend was started many years after great prosperity and success in the other industries. As an example, in comparison with the more developed automotive industry, the construction industry has been weighing the pros and cons of doing automation, and it is still under development. Despite some limitations and lack of information over the 80’s and even 90’s, but the current status indicates good progress. Today, most of architectural design is no longer possible without computer technologies. The models have become more complex and require advanced tools to understand design codes and implement fabrication processes. It can be said, that the advanced automated tools with a user-friendly programming system can bring incredible solutions for architects and construction engineers. Many researchers have made significant studies to consider all possibilities and limitations of digital design-construction in various types of procedures.
Computer integrated manufacturing is a relatively new technology arising from the application of many computer science sub disciplines to support the manufacturing enterprise. The technology of CIM emphasizes that all aspects of manufacturing should be not only computerized as much as possible but also linked together via a computer communication network into an integrated whole. In short, CIM has the potential to enable manufacturers to build cheaper, higher-quality products and thus improve their competitiveness.
