(2024) Modelling the operations of a circular economy fashion start-up. Procedia CIRP, Volume 120, 2023, pp. 1618-16232212-8271https://doi.org/10.1016/j.procir.2023.12.005https://dspace.lib.cranfield.ac.uk/handle/1826/20721Presented at: 56th CIRP International Conference on Manufacturing Systems 2023, 24-26 October 2023, Cape Town, South AfricaThis paper presents a case study of Pantala, a fashion start-up, intending to operationalise a circular supply of luxury womenswear through a monthly subscription-fee model. To optimize the company's cashflow and ensure success, the operational flows were modelled and analysed through discrete-event simulation techniques, with a focus on inventory management and minimizing operational costs. Simulation results demonstrated a high level of accuracy in predicting system performance, with an average relative error of less than 5% for most performance indicators. Insights are provided into the benefits of using simulation modelling for operational planning and optimization of complex systems, especially in the case of start-ups.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/start-upcircular fashiondiscrete-event simulatione-tailingfast-fashionreverse logisticsArticle
