  • Mass Customization.

  • Is it still ok to mass produce thousands of standard products and put them out there in the market pushing customers to buy them? Do we still need to mass produce huge quantities of products whereas many will not be sold and be transformed into waste?
    We are each unique and hence we want unique products and services. These can be obtained when the customer (us) contributes to the design of the product and not only buys what is already produced. Mass customization allows to produce just what the customer wants as he wants it. Hence reducing unneccessary waste and stopping overproduction.
    In order to produce high variety products that are each different and customized by the customer and at very small quantities, we need new flexible manufacturing systems, such as reconfigurable manufacturing systems who can be rearranged in order to produce different products.
    We also need modularity, that allows us to have different modules that can arranged in many ways to form different products. Modularity saves money and time while allowing to offer high variety and customized products.


    Considering the economy's evolution, industrial processes must adapt and meet production needs to address new customer expectations, namely products allowing them to express their individuality. This evolution combines with other challenges such as globalization, technological advancements, the emergence of new materials, market segment diversity, etc., resulting in requirements and specifications of a very different nature. This compels companies to offer a greater variety/diversity of products to better meet market needs and migrate towards flexible production systems. Environmental impact and sustainable performance issues further push companies to produce only what is necessary and demanded by the customer. All these factors drive companies to offer customized or personalized products to the customer. However, offering a greater variety of products or customizable/personalized products increases the complexity of managing industrial processes. This diversity impacts the entire product life cycle and is linked to logistics and pre-and post-sales services. Furthermore, migrating to flexible production systems requires an evolution in production and supply chain management methods and tools, particularly within the framework of Industry 4.0.


    My research aims to develop new methods for optimizing production systems or the supply chain to offer highly diverse or customizable products while maximizing their economic and/or environmental performance. The main contributions are as follows:

  • Proposal of an approach and a discrete event simulation tool to determine the optimal configuration of the production chain and supply chain to increase performance while offering a wide variety of products.
  • Proposal of various mathematical formulations for production management for reconfigurable manufacturing systems with different approximate resolution approaches and reinforcement learning algorithms. Some formulations focus solely on economic performance, while others integrate environmental performance or customer satisfaction.
  • Proposal of mathematical formulations for the integrated combinatorial optimization problem of customizable product configuration and production system configuration optimization. This has led to the development of an online demonstrator. The different formulations differ in the considered manufacturing system's reconfigurability level.
  • Proposal of a comprehensive distributed and dynamic approach for optimizing the production planning of a cellular manufacturing system producing customizable products. This approach includes real-time supply chain data. Two approximate approaches have been proposed and combined with NSGAII and SMPSO metaheuristics to solve the optimization problem.
  • Proposal of a methodology based on the Analytical Hierarchy Problem (AHP) approach for the design and optimization of reverse supply chains.

  • Title: VALUE NETWORK MODELLING AND SIMULATION AS A STRATEGIC DECISION SUPPORT SYSTEM FOR MOVING FROM MASS PRODUCTION TO MASS CUSTOMIZATION
  • Mass customization (MC) has become a reality and an important strategy for survival in today's economy. It is defined as producing customized products at a cost similar to that of mass production (MP). However there are several ways to offer customized products, such as adding customized services, chosing among different colors, combining different modules, and co-designing the product. Since 1993, several works have helped companies in several specific areas, such as tools for designing mass customized products, tools supporting the interaction with the customer, etc…Nevertheless, one question remains unanswered: how to decide to move from MP to MC? How to evaluate this opportunity to improve the performance of the enterprise? How to decide what type of MC to put in place? What are the most important factors to drive? And how to evaluate the transition from a MC system to that of MP? To address these issues we propose a decision support method and tool to move from MP to MC. Our approach consists of evaluating the enterprise’s performance by modelling and simulating a value network. Our scientific proposal is validated via a case study from the footwear industry. We use the SimulValor language to which we have made some improvements, and a discrete event simulation system in which we created our own library of value network. The main indicator of performance is the value generated for which we propose a model that is combined with the conceptual model of the value network. The combined models are simulated and evaluated to help determine the transition from MP to MC considering not only profit, but also delays, costs and customer satisfaction.
