Intelligent algorithm development for complex manufacturing process

Identify the current challenges and developing machine learning based intelligent algorithms for complex manufacturing systems

Details

  • Marine, aircraft, most of the automobile parts like engine fan blades, wings, fuselages, etc., are made out of matrix composite. Reducing its weight (without compromising the strength) is critical to achieving higher fuel efficiency. Therefore researchers/scientists are engaged to discover lightweight composite materials. Dimensional changes geometrical distortions of the fabricated part are inevitable due to the thermal expansion mismatch between the progressive stages of the fabrication, shrinkage of the resin, variation of the degree of the cure gradient through the thickness.

    In this manufacturing process, uncertainties are expected at any stage of the fabrication process and propagate through the entire processing cycle, resulting in poor outcomes and rejection of the whole part. We have developed AI/ML-based algorithms for composite manufacturing uncertainty propagation analysis. Statical analysis was conducted to check the performance of the proposed algorithm. It shows that the proposed optimization algorithms are promising with low prediction deviation and high accuracy.

    The outcomes of the research studies are submitted to peer-reviewed journals.

Development of optimization algorithm
improved Firefly Algorithm (iFA)

The firefly algorithm is a nature-inspired, population-based metaheuristic algorithm that mimics the flashing and movement behavior of the fireflies. The brightness/attractiveness of the fireflies is a relative term. It depends on the distance between any two fireflies, shape and type of the landscape, and few environmental factors. In this improved version of the firefly algorithm, few rules have been proposed to keep a better balance between the exploration and exploitation capabilities of the algorithm.

Web Based Development

Design and Development of an Open Innovation Platform

Details

  • Developed an intelligent, robust, modular, responsive, secure system with various different roles with different activities and privileges involved in this platform. The goal of this platform is to tap human resources and empower the world’s largest democracy with advanced technologies for a self-sustained economy. To achieve these, the Department of Heavy Industries (DHI), ministry of heavy industry, Government of India, and Public Enterprises initiated the creation of a platform to ally enterprise/industries and individual stakeholders.
    Under the aegis of DHI, the Central Manufacturing Technology Institute (CMTI) decided to start their open innovation platform called “Drishti” - Design, Research, and Innovation by Harvesting Science and Technology for Industries. It currently engage, innovate and collaborate between 5000+ innovators and industry partners across the world. The platform link can be found     here.
