| Abstract | GM model is the core of grey system theories. It has been widely applied to social, economic, agriculture, industrial and many other fields. It has solved lots of problems of scientific and technology. In 1982, professor Ju Long Deng published the first research paper about the grey systems, and established GM(1.1). Many scholars have improved it since then, and a series of prediction models have been established, the literature on GM is now voluminous, such as DMG, Verhulst and so on. All the models make an optional data of the raw sequence as background condition,they all look one data as the system's real value, these man-made conditions may led to the inexact in the simulation and prediction of the time response sequence, because they have many occasional factors. In order to prove the precision of these models,in this paper , we think that all the system's initial data must not be ignored , all of them can affect the system, then we develop a new model, after the development coefficient and the grey action quantity are given, we utilize "the least square" to find the constant number in the common solution of GM in this paper, then, gain an optimum time response sequence.In this paper we also proved that the optimum GM(1,1) is the best-fit line and it has superior precision in simulation and forecasting than traditional one. So, this paper has high value on theory and application. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
