  operation research : It’s goal and history

  In many dictionaries ,the word ,OR, has been lexically interpreted to mathematical and scientific analysis of a process or an operation in order to take a decision.some assume that this topic was coined by charles babbage (1791-1871) because of his large scale researches about cost of transportation and organizing of postal packages in 1840 and also studying the behavior of rail transportation equipments.

  What is OR?

  Briefly ,OR , is the knowledge to apply developed analytical methods in order to take better decisions.Using methods like ,mathematical modeling for analyzing complex situations ,OR gives the executive managers the ability of taking more appropriate decisions and creating efficient and beneficial systems in some cases such as :

  · complex data sets

  · Considering the whole existing conditions and limitations

  · Exactly forecasting the results and risk evaluation

  · applying the most advanced methods and decision tools

  A unique approach to decision

  perhaps you have seen dozens of papers and articles about the solutions which claim that they can make taking decisions easier for you.

  everyday organizations and the world we are working in, are getting more complicated .plenty of choices and time limitations and marginal decisions in relation to issues around ,have made them harder. In this regard ,applicative softwares which are producing and processing every day ,use lots of data and can open new doors to taking more appropriate decisions. so the OR article can be used in challenging fields with a large number of variables and also numerous risks in a proper way.

  · optimum investment in the absence of that financial security or existing pharmaceutical and health inventory is considered.

  · deciding based on how much budget to spend for conventional or internet sales
