Flexible Systems Management
All disciplines which are available in the world, including management. For the development of any science, technology, business, management discipline, uses the previous available research knowledge as background, The trend of integration in different systems is emerging very rapidly, in the field of both system methodology and decision making in the field of support systems and artificial intelligence. Flexible Systems Management, will serve as a research method for management in the developments of new paradigm, trends and flexibility. Flexibility in system management means the ability to deal with slightly or the variation in the process sequence. Flexibility is used as a characteristic of a wide variety of systems. In the field of engineering systems design, it refers to a system designs that can adapt external changes when external changes occur. Flexibility is defined differently in many areas such as engineering, architecture, biology, economics, and more. Engineering can define flexibility in terms of design as the ability of a system to respond to potential internal or external changes that affect its value, in a timely and cost-effective manner. Thus, flexibility for a system is to respond uncertainty in order to maintain or enhance its value distribution. Uncertainty is the main key element in the definition of flexibility. Uncertainty is responsible for create both risk and opportunity in a system, existence of uncertainty that flexibility becomes valuable. John Atkinson's Flexible-Firm Model) is a managerial and organizational technique used to optimize the allocation of human resources according to market volatility and workforce flexibility. It defines two distinct groups of workers, the core and peripheral groups, which are organized within the company based on three types of flexibility: functional, financial and numerical. There are different types of flexibility which are given below.
Machine flexibility is the ability of a given machine to produce a wide range of production operations and different products design and styles. The greater the range of operation process and part styles of the machine, the greater the flexibility of that machine. The various factors on which a machine's flexibility depends are the setup or turnaround time, various programs can be downloaded to machines, the equipment storage capacity of machines, and the efficiency of the machines.
Production flexibility is the range of producing products that can be built on the system. The range of products styles that can be produced by a manufacturing system at reasonable cost and time is determined by the process evolved into production. Production flexibility depends on many factors including the machine flexibility, range of machine in the system.
Mix flexibility is the process of changing the product mix while maintaining the same total production volume, which produces the same parts only in different ratio. This is called process flexibility. Mix flexibility is used, for provides protection from market volatility by changing product mix by the use of shared resources. However, higher mixing variations are required for greater numbers of equipment, fixtures, and other resources. Depending on factors such as composite ductility, uniformity of parts in the mixture, machine flexibility, and relative work material time of the produced parts.
Product Flexibility. is an ability to change new requirements of products economically and rapidly according to market requirements. The change over time is required for designing, planning, tooling, and fixturing of new products in the manufacturing line-up. Product Flexibility depends upon new part design with the existing part family. Off-line part program preparation and machine flexibility
Routing Flexibility is defined as the ability to produce parts at an alternative workstation in case of equipment breakdown, equipment failure and other disruption at a particular station. This helps to increase output in the presence of external changes such as product mix, engineering changes, or new product introductions. Factors that determine routing flexibility include uniformity of parts in the mix, uniformity of workstations, and general tooling.
Volume flexibility is the ability of the system, to vary production volumes of different products to accommodate changes in demand while remaining attractive. It can also be called capacity flexibility. Factors affecting volume flexibility are the level of manual labor performance output, the amount invested in capital equipment,
Extension flexibility is the process by which the system can be expanded to increase the total production volume. Expansion flexibility depends on many factors including the cost of adding new workstations and trained workers, expansion of the layout, type of part handling system used.
