| Abstract | For most of the transportation system in semiconductor fabricating bay, the requests for transportation are given in every few seconds. It is necessary to determine the allocation of the transportation requests to AGVs and the route planning of AGVs without collision and deadlock in a dynamic environment. In this paper, we propose an autonomous decentralized route planning method for dynamic route planning. In the proposed system, each AGV individually derives the route for itself by repeating the generation of the route for each AGV and the wireless communication with other AGVs. Each AGV has a function of optimizing the route for itself. However, it is desirable that a rescheduling is executed locally as much as possible. From that viewpoint, we propose a rescheduling algorithm for dynamic environment. From the numerical experiments, it has been demonstrated that the proposed method can reduce 80 percent of the computation time compared with the conventional autonomous decentralized method without lowering the performance level. Moreover, the proposed method has been implemented on a parallel experimental system and it has been demonstrated that each robot can successively travel without deadlock and collision among AGVs. |

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.
