| Abstract | Floor level control systems such as scheduling and production monitoring systems differ from conventional software systems of plant, once they are highly integrated with the physical production system. Similarly to sequential control systems, the plant and the control system may not be considered independently, once both are mutually dependent. This is an extremely complex issue specially when dealing with the integration of the plant floor level with other higher levels of the system also when dealing with new requirement of safety, variety and speed. This work proposes a modeling technique based on colored Petri nets (CPN) which allows not only the hierarchical modeling of data and material flow in the system on the same model, but also with clear division and representation of interactions among the production and data handling components. Advantages of the authors' CASE (computer aided software engineering) modeling technique are demonstrated by applying it to the development of a distributed scheduling and monitoring system of a multi-layer PCB board production line. The generated plant model was used to the analysis and evaluation of the production process. The same model was used for the proposal and validation of a distributed and dynamic scheduling system, and also a production monitoring system. The proposed approach may also be used for allowing a smooth of the integration of plant floor level with higher level control and administrative systems. |

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.
