Publication number: 20230104356Abstract: All the model-driven systems may not have capability to perform designing and execution of experiments, which limits functionality of such model-driven systems. The disclosure herein generally relates to Design of Experiments (DOE), and, more particularly, to a model driven sub-system for design and execution of experiments. The sub-system when plugged into the model driven system, uses legacy components as well components of the sub-system to perform designing and execution of the design of experiments.Type: ApplicationFiled: March 27, 2021Publication date: April 6, 2023Applicant: Tata Consultancy Services LimitedInventors: ARPIT VISHWAKARMA, PRASENJIT DAS, PURUSHOTTHAM GAUTHAM BASAVARSU, SREEDHAR SANNAREDDY REDDY, AMOL DILIP JOSHI

Publication number: 20220318676Abstract: The disclosure generally related to a learning-based modelling of an emergent behavior of a complex system. Existing decision-making at complex systems primarily relies on qualitative approaches, which often results in inaccurate outputs. The disclosed system includes a digital twin of the complex system and a digital twin of an environment of said complex system, and captures an interaction and dynamic behavior of agents of the digital twins. The agents of the digital twins are simulated and modelled using learning-based models such as RL and genetic algorithms that learns the behavior (i.e. actions and their outcomes) over a period of time. Hence, the agents (or actors) of the digital twins are dynamic in nature. The actor-based bottom up simulation approach is capable of producing sufficient insight for effective decision making prior to implementation.Type: ApplicationFiled: September 17, 2021Publication date: October 6, 2022Applicant: Tata Consultancy Services LimitedInventors: PRASENJIT DAS, SOUVIK BARAT, VINAY KULKARNI, PRASHANT KULMAR, KAUSTAV BHATTACHARYA, SANKARANARAYANAN VISWANATHAN

Patent number: 11320955Abstract: The present disclosure is related to a system and method for controlling widgets of a table on a display using a server. The system is configured to receive inputs from user for controlling widgets of the table by specifying at least one configuration at the server end for at least one of a plurality of predefined configurations. It determines a plurality of events and invokes at least one event handler at the server end according to a predefined interface for the determined event. The event handler would then provide the component with response behavior. Further, the system specifies a plurality of observable properties wherein any change in the properties would be automatically tracked by the system and invoking the specified at least one event handler to control at least one widget of the table.Type: GrantFiled: November 27, 2018Date of Patent: May 3, 2022Assignee: Tata Consultancy Services LimitedInventors: Aswin Rajeev, Prasenjit Das, Anagha Nikhil Mehrotra

Publication number: 20210216896Abstract: This disclosure relates generally to recommending tool configurations in machining. The machining tool configuration selection involves the selection of several tool specification parameters concerning the material, geometry and composition of the machining tool. The state-of-the-art methods uses a rule and knowledge-based system to select tool configuration, however these methods do not recommend tool configurations which satisfy customer requirement. Embodiments of the present disclosure uses a hierarchical model which is trained to predict acceptable tool specification parameters for a given requirement by learning the patterns from past tool selection data. Further a probabilistic approach is used to predict the top set of recommendations of tool configurations with a probability score for each prediction. The disclosed method is used for recommending tool configurations in a cylindrical grinding wheel process.Type: ApplicationFiled: December 3, 2020Publication date: July 15, 2021Applicant: Tata Consultancy Services LimitedInventors: Sunil SHARMA, Bilal MUHAMMED, Srimannarayana PUSULURI, Purushottham Gautham BASAVARSU, Prasenjit DAS
