Q.1 Define MIS? What are the objectives and characteristics of MIS?Ans
management information system
) is asystemor process whichprovides information needed to manage organizations effectively. Managementinformation systems are regarded to be a subset of the overallinternalcontrolsprocedures in a business, which cover the application of people,documents, technologies, and procedures bymanagement accountantsto solvebusiness problems such as costing a product, service or a business-widestrategy. Management information systems are distinct from regular informationsystems in that they are used to analyze other information systems applied inoperational activities in the organization. Academically, the term is commonlyused to refer to the group of information management methods tied to theautomation or support of human decision making, e.g.Decision SupportSystems,Expert systems, andExecutive information systems.
At the start, in businesses and other organizations, internal reporting was mademanually and only periodically, as a by-product of the accounting system and withsome additional statistics, and gave limited and delayed information on management performance. Previously, data had to be separated individually by the people as per the requirement and necessity of the organization. Later, data was distinguishedfrom information, and instead of the collection of mass of data, important, and to the point data that is needed by the organization was stored.Early on, business computers were mostly used for relatively simple operations suchas tracking sales or payroll data, often without much detail. Over time theseapplications became more complex and began to store increasing amounts of information while also interlinking with previously
information systems.As more and more data was stored and linked man began to analyze this informationinto further detail, creating entire
from the raw, stored data.The term "MIS" arose to describe these kinds of applications, which were developedto provide managers with information about sales, inventories, and other data thatwould help in managing the enterprise. Today, the term is used broadly in a number of contexts and includes (but is not limited to):
people management applications
, project management and database retrieval application.An 'MIS' is a planned system of the collecting, processing, storing anddisseminating data in the form of information needed to carry out the functions of management. In a way it is a documented report of the activities that were plannedand executed.According to

- A system that consists of numerous programmable machine tools connected by an automated
material handling system”.
A flexible manufacturing system (FMS) gives manufacturing firms an advantage in aquickly changing manufacturing environment.
Characteristics of FMS
- There are following characteristics of FMS as:
It is an attempt to solve production problems of mid-volume and mid-variety parts.
It is designed to process several parts in the given mix simultaneously.
It is equipped with sophisticated flexible machine tools
Faster, lower-cost changes from one part to another which will improve capital utilization
Lower direct labor cost, due to the reduction in number of workers.
Reduced inventory, due to the planning and programming precision
Explanation of system designed to produce components
- A Flexible Manufacturing System is one that can bechanged or adapted rapidly to manufacture different products or components at different volumes of production.Flexible manufacturing systems are usually seen at their most efficient when manufacturing components rather thanfinished products.Machine Flexibility: When machines are used to manufacture a variety of products/components this is called
‘machine flexibility’. A good example is a company that
specializes in manufacturing injection molded components.The component design may change very quickly but as long as the mould is updated / modified the injection moldingmachine can still operate. Computers monitor the supply of materials; monitor the operating temperatures and qualitycontrol. Machines of this nature are adaptable and are ideal for FMS.
Flexibility in the manufacturing process
- Flexible manufacturing systems are being designed with other type of processing equipments including inspection stations, assembly works and sheet metal presses. Increasingmanufacturing flexibility is a key strategy for efficiently improving market responsiveness in the face of uncertainfuture product demand.
Components of FMS
In present day application these workstations are typically computer numerical control (CNC)machine tools that perform machining operation on families of parts. The various workstations are
Load and unload stations
Assembly work stations
Sheet metal processing, etc.
