Additive manufacturing of spare parts significantly impacts industrial, social, and environmental aspects. However, a literature review shows that: (i) academic papers on the adoption of additive manufacturing have focused mainly on large companies; (ii) the methods required by SMEs to adopt new technologies differ from those employed by large companies; and (iii) recent studies suggest that a suitable way to help small- and medium-sized enterprises (SMEs) to adopt new additive manufacturing technologies from the academic world is by presenting case studies in which SMEs are involved. Given the increasing number of global SMEs (i.e., SMEs that manufacture locally and sell globally), we claim that these companies need to be assisted in adopting spare-parts additive manufacturing for the sake of resource and environmental sustainability. To bridge this gap, the purpose of this article is to present a case study approach that shows how a digital supply chain for spare parts has the potential to bring about changes in business models with significant benefits for both global SMEs (more effective logistic management), customers (response time), and the environment (reduced energy, emissions, raw materials, and waste).

El artículo, presenta un modelo de desarrollo productivo basado en un análisis de la cadena productiva del sector pesquero español. Está construido gracias a un diagnóstico del comportamiento de cada eslabón de la cadena de diferentes organizaciones de ciencia y tecnología. El modelo determina teóricamente cantidades óptimas, precios y beneficios económicos usando la teoría de juegos, el equilibrio de Nash y el óptimo de Pareto, siguiendo criterios de los modelos de Cournot y Bertrand para productos poco diferenciados y con tamaños de mercado similares. Los resultados obtenidos muestran que cada unidad de producción pesquera tienen que capturar, procesar y vender en promedio 280 kilogramos por día, con el fin de maximizar su eficiencia económica.
