Operations and Supply Chain Management and Optimisation

Today’s global competitive business atmosphere, stringent concerns from environmental, social, risk and uncertainty requirements have affected global supply chain network structures for manufacturing and service industries. As a result, firms have to restructure their supply chain orientation to be more cost-effective, more sustainable, more flexible, more adaptive, more resilient, more robust, and more responsive to customer requirements and changing global markets.

Our research pioneers in applying agent-based technology in modelling, simulating and optimising the configuration of multi-objective global supply chain network designs. Our solution frameworks and methodologies ranges from simulation, exact methods, metaheuristics (i.e., genetic algorithms, ant colony optimisation, bee colony, etc.), hybrid approaches (i.e., matheuristics, artificial intelligent, machine learning, etc.). The goal is to provide sustainable competitive advantages for companies.

Our research focuses on but not limited to

  • multi-objective optimisation of supply chain operations to reduce cost, carbon emissions and delivery time;
  • a coordination of project-based supply chains with dynamically changing project portfolios;
  • model sourcing and inventory decisions in a multi-tier supply chain and the coordination and optimisations of such decisions across supply chain member; and
  • design resilient and robust supply chain network design to incorporate uncertainty, risks, and disruptions (i.e., demand, supply, natural events, etc.)

Our research covers a broad range of issues associated with supply chain, which currently focuses on the following sub-areas:

  • Discrete Event Simulation of Manufacturing Processes
  • Logistics Management
  • Operations & maintenance of offshore wind energy
  • Project supply chains and dynamic portfolio management
  • robust and sustainable resilient supply chain network design
  • Sustainable Closed-loop supply chain management

Projects

KTP with Smart Manufacturing ltd Bideford (Academic supervisor: Prof Voicu Ion Sucala, KTP Associate: Sam John Abraham)

This KTP project is creating and implementing a dual-production business model and a novel modelling and simulation tool to enable the optimisation of multi production manufacturing flows. This is enabling Smart Manufacturing to design and manufacture new and highly specialised equipment for ATEX rated environments in parallel with its traditional bespoke products. The KTP also developed a novel knowledge management tool that helped Smart Manufacturing acquire and formalise the highly specialised knowledge on ATEX regulations and practices. Work is ongoing to extend and generalise this tool so that it can be used by manufacturing SMEs to consolidate compliance knowledge in resource constrained environments.

EPSRC Internet of Food Things Network Plus on "DISTINCT: IoT and big data for productive, safe and sustainable aquaculture" (PI: Dr Miying Yang, Co-I: Dr Martino Luis)

The project seeks to explore digital technologies and new business models to improve aquaculture farming productivity, food safety and sustainability across supply chain. This project captures the challenges across the aquaculture supply chain, uses Internet of Things and big data to help aquaculture farmers monitor the changes of the farming water, so that they can better control water quality, take preventative actions to reduce death and disease, and reduce environmental impact.

BINDER - sustainaBle supply chaIN and market opportunities iDentification for waste tilE powder (PI: Dr Martino Luis and Dr Raffaele Vinai)

The project focuses on transforming non-marketable ceramics and porcelain (a waste stream which is financially costly and has high carbon emission rates) into PORCEMENT - a highly profitable cement-like material to substitute concrete binders. The project was funded by the UKRI National Interdisciplinary Circular Economy Research programme (NICER) programme.

We teamed up with PORCEMENT Ltd and ARC MARINE Ltd to develop new product and processes where porcelain and ceramic waste will be reused and processed as supplementary cementitious materials. The project addresses the three principles for circular economy as proposed by the Ellen MacArthur Foundation: Eliminate waste and pollution; Circulate products and materials at their highest value; Regenerate nature.

Our experiments demonstrated the suitability of tile powder use as supplementary cementitious materials and could save up to 20% carbon emissions. The design of sustainable supply chain operations ensured that material flows (supply- demand) were collected and distributed optimally considering transport pollution reduction. It created a step-change in adoption of circular economy approaches, by validating the feasibility and profitability of using waste products as supplementary cementitious materials.

The project outputs have opened future research avenues in the field of industrial symbiosis, which is part and parcel of circular economy. Thus, researchers in industrial symbiosis will also benefit from the results of this project.
