| Studies based on economic theory rests on two pillars are the study of micro-economic Micro, which deals with a single economic unit (enterprise, organization, project) while macroeconomic Macro interested in studying the economy as a whole. And this study fall within the micro-economic studies. As production planning process occupies a prominent place in the economy, which is the backbone of modern civilization. We live in different images of the economies of the global mismatch of the capitalist economy and socialist economy and planned economy, which is currently the most common model, which is the case of an advanced capitalist economy professionals starting from the time of economic recession in 1929, but production planning institutional occupies paramount importance regardless of the picture (s) of world economies , and varied in its side application, where the large institutions and the expansion of its activity the decisive factor and the compressor in the adoption of production planning to achieve the objectives of these institutions, and finds Kalprat (JK Galbrath) that the requirements of huge capital required by modern technology requires that the consumer and the market subject to the programming and institutional planning. It seemed it is recognized that the practical application of methods and modern scientific methods at the micro level (enterprise) maximize profits and enhance their efficiency, and seemed departments considered an essential means to solve the big problems and to find optimal solutions to them. And that the adoption of the technique of modern research methods including the standard is a feature of contemporary economic analysis. So focused departments primarily on the production planning and compression costs were the economic theory of partial scientific basis for improving the economics of the enterprise, especially since the institution and in conditions of free competition were not able to control the market because they produce along with many similar institutions, and that its production is only part simple of the total supply in the market, so the production planning through the use of technique mathematical and statistical and quantitative analysis developed is a way of administration for the continued production and maximize profits, especially since the problems today are complex and large and in need of technique advanced to follow the mutual influence between economic variables. And it certainly will be in front of economists in the present and the future face of the case (need to) use the large and the salt of Mathematics and Statistics, it was zero at the time of economists first and then develops into a simple geometry and algebra and calculation of differentiation and integration in (1900) and then to the arrays and theories of the logic of symbolic and finally arrive at the methods many in operations research, and it will take to constantly economist mathematical tools to deal with the problems of large, complex, and here starts the decisive progress forward. |
