| Abstract | In this paper, nonlinear time series techniques are applied to analyze the peak elevator traffic flow data. The phase space, which describes the evolution of the behaviour of a nonlinear system, is reconstructed using the delay embedding theorem suggested by Takens. The embedding parameters, e.g. the delay time and the embedding dimension are estimated using the mutual information of the data and the false nearest neighbor algorithm, respectively. Numerically the attractor of the elevator traffic flow from reconstruction is not necessarily sufficient indication of chaos, therefore we then calculate the correlation dimension of the resulting attractor and the largest Lyapunov exponent. It is demonstrated that the traffic flows of the up-peak and down-peak all exhibit low-dimensional chaotic behaviour. The result will help to adjust the group control scheduling methods according to the chaotic behaviour of the peak flow so as to increase the performance index. |

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.
