| Abstract | In order to circumvent the state explosion problem involved in the analysis of a reachability graph, the structure theory is widely adopted when dealing with deadlock control and liveness-enforcing problems of flexible manufacturing systems modeled by Petri nets. Siphons, as a kind of significant structural objects, are extensively used for the deadlock prevention. However, since a siphon is defined as a set of places and does not contain any weight information, the siphon-based methods encounter a series of problems when dealing with generalized Petri nets whose arc weights are equal to or greater than one. As a concept different from siphons, augmented weighted simple directed circuits are proposed in our previous work to investigate a kind of intrinsically live structures in general systems of simple sequential processes with resources allocation $(GS^{3}PR).$ The work extends the concept of resource usage ratios (RU-ratios) to $GS^{3}PR$ to explore such intrinsically live structures. On the ground of RU-ratios, a kind of liveness and ratio-enforcing supervisors is applied to control $GS^{3}PR$ models. The monitors in such a supervisor are simply and intuitively connected to a plant net model and can be reused by adjusting their parameters when the configuration of the plant is changed, which resembles the working style of a programming logic controller. Several examples are used to illustrate the proposed method. |

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.
