Diwate1, Kavita S. Pokarna2 Assistant Professor1, U.G.Scholar2 J.D.I.E.T., Yavatmal, Amravati University Abstract-Now a day’s open source software is purpose [1]. Due to code distribution polices of widely market dominating product. There are open source software, now a day’s number of multiple options are available for operating operating system are made available in the system. In this paper we focused on selection of market, But as soon as latest versions are operating system with the applicability of released many options are available and Multi-Criteria Decision Analysis (MCDA). confusion occurs. Open source technology is Multi-Criteria Decision Analysis (MCDA) has often a smart choice for designers looking to been extensively used in Management Science stay competitive. It provides the means to keep as a tool for evaluating options in decisions down costs while increasing system which involve the achievement of multiple efficiencies. For designers and developers objectives. MCDA is can be applied to the striving to strike a balance between resources selection of operating systems (OPS) in a group and requirements, open source software, while decision environment. A OSSP selection model not always as pretty as its more expensive is proposed to facilitate the group's decision counterparts, is a viable solution. Open source making in the selection of OSSP.

Following diagram shows the general security frame work for selection criteria for selection of Linux was designed from the outset as a multi- operating system. user, multi-tasking PC version of the most popular business O/S Unix - which has been around for a long time and is used by most businesses to run their Data Processing departments. Linux is light on resources Linux is smaller and less resource intensive, allowing it to run on old hardware or low specification PCs.

Linux has a lot of advantages over the "usual Multiple-criteria decision-making or suspects", including the following: multiple-criteria decision analysis (MCDA) Linux is free! is a sub-discipline of operations research that You can download it off the web: there is also explicitly considers multiple criteria in no licensing cost for installing it to multiple decision-making environments. Whether in our PCs daily lives or in professional settings, there are Linux is available in lots of different typically multiple conflicting criteria that need “flavors”: to be evaluated in making decisions [9]. If you have a particular use in mind for your Multi-Criteria Decision Analysis (MCDA), a PC, then there is probably a tailored version of methodology for supporting decision making Linux out there just for you when multiple objectives have to be achieved 109 Mr. Rahul B.
