A. Reconfigurable Manufacturing System (RMS)
A reconfigurable manufacturing system is a system designed for rapid adjustment of production capacity and functionality, across a product family by rearrangement or change of its components (hardware and software). RMS is a modern system that bridges the gap between DML and FMS. Its design is focused on producing a particular family of parts rather than an infinite range of parts limited only by the machine’s geometric and operational envelope, as is the case in FMS. The RMS trades a bit of flexibility for higher throughput. While it does not provide the general flexibility that FMS offers, it can have just enough flexibility (i.e. functionality) to produce the whole part family for which it was

RMS may be defined as the machine system which can be created by incorporating basic process modules both hardware and software that can be arranged or replaced quickly and reliably. (Mehrabi et al. 2000; ElMaraghy 2006)
Furthermore, the RMSs are designed for a specific range of production requirement as opposed to a single set or the wide range of the product requirements. However, the production system can be reconfigured if the product requirement changes by adding, removing, or modifying specific process capabilities, controls, and software or machine structure. It can also accommodate any change in the technology thus prove to be efficient and cost effective in long run unlike its predecessors—DMS and

different variety of existing product and quick adaptability for the future products.
4) Diagnosability: The identification of the correct set of process in order to improve the efficacy, which is a key step to reduce the ramp up time in RMS
5) Customization: The design of machine flexibility limited to just a product family thereby obtaining customized flexibility.
6) Scalability: The ability to easily modify the production capacity by adding or subtracting manufacturing resources (e.g. machines) and/or changing the reconfigurable components of the system.
C. Comparisons of Manufacturing Systems
The RMS was adopted to overcome the limitations of the DMS and FMS. The RMS can be differentiated from both of the existing systems on the basis of three coordinates which are: capacity, functionality and cost. As the RMS possesses adjustable capacity and functionality and since it is focused around the part, makes it cost effective. Fig 1 and 2 gives the comparison of RMS, FMS and DMS with respect to cost and performance.

Few systems for example: an embedded system is safety critical when installed in a vehicle. Such systems are extremely expensive to change; others must change frequently in response to varying requirements (e.g. business systems). Systems which are very expensive to change need extensive in advance analysis to ensure
The initial phase of this implementation is to focus our priorities on implementing this new technology at CanGo and to present a quality product, which will entail our coverage and research into the flexibility, costs, maintenance, capacity, space and the long-term benefits of CanGo investing in an ASRS. In addition, we will be reviewing and comparing the firm with other small firms and their utilization of their ASRS system and how a highly advanced system will bring flexibility, productivi...

...ns. Thus optimized systems to meet the challenges of extreme workloads are required by organizations because of all this. To offer packaged hardware and software solutions that are optimized for analytical processing has been the response given by the industries.
Flexibility is important of firms an operation that enables it to react to their customers quickly and efficiently. Some companies use they two types of flexibility: the customization or the volume flexibility. Customization is usually the ability to satisfy the unique needs of each customer by changing products or services design, with different features, or making them look unique. Primark’s uses both operations. To satisfy their customers need. While volume flexibility is the ability to quicken the rate of their productions to handle large variations in demand.it is usually important for operations. Both companies use both operations.
Economies of Scale: - Company had to have a substantial amount of orders in order to earn economies of scale. Otherwise the cost of production would usually be more than the selling price of the aircraft.

Functional: This refers to a firm’s ability to adjust and deploy the skills of its employees to match the tasks required by its changing workload, production methods. This is done by multi-skilling / dual skilling / dismantling of traditional rigidities between occupational groups (horizontal and vertical flexibility). This is designed to improve efficiency and reduce costs.
Thanks to cutting edge technology and robotic systems, all these aspects can be considered through data integration and process programing.
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.
Operations – To work out the right layout and work flow process in the company. The manpower resource allocation is also critical in the situation on the right balance of resource to handle the production. If possible, adopt a hybrid model to handle the flexibility in the product nature, make both the production line being able to configure standard and customized so to reduce setup and changeover time and cope with the demands.
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.
Manufacturing Execution: consistency on manufacturing throughput the cycle of production with different execution capabilities to ensure maximize production flexibility, improve execution process and increase efficiency of the plant by planning and management of inventory.
DSS may provide support to all phase of the decision-making process and to all managerial levels, both for individuals and groups. DSS is designed to support complex managerial problems that other computerized techniques cannot. DSS is user-oriented, utilizes data and frequently models. DSS can improve the effectiveness of decision-making, decrease the needd for training, improve management control, faciliate communication, save effort by the user, reduce costs and allow for more objective decision making. DSS can be used to support individuals or it can be used to support decisions made by groups
