Managing Information Systems The aim of this assignment is to see the requirements for developing and managing a comprehensive Management Information system for an organization. In today's business environment it is getting harder and harder for organization’s to not only survive but to compete against other organizations. Information technology plays a big part in helping companies compete and survive. Companies that have branches or franchises need to make sure that they can communicate with the head office so that orders can be passed down. Most of a mangers time is spent 1 Passing information and ideas upwards to senior management to aid their decision making 2 Providing other department managers with information which will help them do their jobs more effectively 3 Passing information down wards to subordinates 4 Conveying attitudes or creating them 5 Receiving and interpreting facts and data 6 Communicating with people out sides the company e.g. suppliers. The manager needs resources to aid him with the task mentioned above. Management information systems and decision support systems are two such resources. Computers and information systems play critical roles in the operation of most organizations. All organizations, from factories to banks, are highly dependent on information for their day-to-day operations. The vast quantity of information that large corporations and government agencies need to operate, and the speed with which that information is created and used, makes computer-based information systems critical to such operations. What is a Management Information System? There are different definitions of a management information system: â€Å"Management Information system products produce information products that support many of the day-to-day decisions –making needs of management. Reports, displays, and responses produced by such systems provide information that managers have specified in advance as adequately meeting their information needs.† Taken from Management Information Systems Third edition by James A.

Costs of residential photovoltaic solar electricity Essay

Abstract Now a day’s electricity is more important concern. We use a lot of home appliances which is operated by electricity but electricity we use; it is costly and not available every where. As we know sun is the source of energy, the energy which provided by the sun, less in cost, mostly available every where in abundance.  Ã‚   Where electricity is not available in that case electricity generation by using solar energy can solve our problem but the main problem is that before apply such a technique, we familiar with installation cost, its limitation, uses etc. In this paper I want to focus our attention Costs of residential photovoltaic solar electricity with battery storage and its installation. Costs of residential photovoltaic solar electricity with battery storage   Sun is the most imp energy source of energy. Energy which is finding from sun is almost free of cost, pollution free and most abundant in nature. The generation of electricity from solar energy is one of the best uses of unconventional energy resources. We can generate electricity from solar energy by two ways one by used to photovoltaic technologies other by used to solar thermal technologies. Photovoltaic cell is the most important means for electricity generation; we use photovoltaic generated power because it is very reliable, low operating and construction cost and pollution free, so its use increases day by day. There are around thirties different devices used now a days. We store this electrical energy in the battery bank. There are around 400,000-800,000 photovoltaic systems operating worldwide its typical size varies from 50 watt to 1 kilowatt (kW) for stand-alone systems with battery storage and small water pumping systems; its cost varies according to use of photovoltaic panel, the average cost of approximately US$4 per watt. Its approx cost for 5000/kw photovoltaic module is $2600 and for photovoltaic system approx 7000/kw is $4700.to accurate measurement of the cost it is necessary we compare it from other energy resources with all aspects. We use photovoltaic module less than 10kw and it is increases according to use. In the beginning the installation cost is much but if we compare it from other resources it is cheaper to use as in the village where no electricity or it may have, the photovoltaic technology provide direct electricity.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚   So the electricity generation by photovoltaic solar panel is cheaper than other electricity generation if we compare it for all aspects.   References:   Gupta, D., Mishra, V.
