| Abstract | This paper deals with operating mode management of discrete event systems (DES) and this contribution is based on supervisory control theory (SCT). Our aim is to extend SCT by introducing a mechanism for managing different operating modes for the controlled system. An operating mode corresponds to a specific system structure (engagement or disengagement of different system components) and specified tasks. Mode management will consist in controlling switching between modes with a view to handling models of reasonable size. Our approach is a multi-model one and involves representing a complex system by a set of simple automata models, each of which describes the system in a given operating mode. The adopted approach assumes that only one attempted operating mode is activated at a time, whilst other modes must be deactivated. The switching problem may be defined as finding compatible states, when controlled system behavior switches from one operating mode to another. The major contribution of this paper is the avoidance of switching from states (called forbidden states) with ghost compatible states in the selected operating mode. These states are called ghost because their existence would potentially violate a defined selected mode specification |

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.
