Using system dynamics for short life cycle supply chains evaluation

Abstract

This work is part of an Italian National Research Project embracing different aspects of a short life-cycle products supply chains: its modeling, its resiliency and its competitiveness. In fact, this particular kind of products, like fashion goods, toys or electronic devices, have different characteristics compared with long-medium life cycle products and this implies a quite different management as well as competitiveness factors to take into account. Starting from the modeling of a supply chain of this kind, utilizing the Powersim Studio Software implementing the System Dynamics methodology, with the goal of showing its behavior under specific scenarios, some vulnerability causes have been considered in order to make the supply chain more resilient. Finally, the competitiveness dynamics between two companies producing short life cycle items has been modeled and analyzed.

“…Powersim was developed as a Windows based _____________________________________________________________________________ ________ Miran Ismail Hussien and Rasha Abd El Aziz (2017), IBIMA Business Review, DOI: 10.5171/2017.904520 environment for the development of system dynamics models that facilitates packaging as interactive games or learning environments (Hussein, 2010). Powersim Studio™ is flexible and allowing the integration with databases, external files and ERP systems (Briano et al, 2010). Hoekema (2011) emphasizes that the Powersim Studio platform provides a powerful user interface that makes the model easier and it is an equally powerful way to build and test system dynamics models of environmental systems.…”

“…y alta repetición en la tasas de compra (Briano, Caballini, Giribone & Revetria, 2010). Además, factores como la moda, la tecnología, los cambios de gustos en los usuarios, y la mayor presencia de competidores, alteran el tiempo de duración de cada una de las etapas.…”

“…La flexibilidad en la gestión de la cadena de suministro para productos con ciclo de vida corto se convierte en un tema de vital importancia, dado que permite reducir la vulnerabilidad y ocurrencia de eventos impredecibles y perjudiciales para las compañías (Briano et al, 2010). La flexibilidad, enmarcada en la capacidad de respuesta, es definida por Ballou (2004) como la estrategia con la cual se busca responder rápidamente a la demanda en el momento que ocurra, no a partir de inventarios, sino de los procesos de producción o de los proveedores (…), evitando largos periodos de entrega o inventarios excesivos.…”

Todos ellos resaltan la gran importancia de una cadena de suministro flexible, dado que brinda a las organizaciones la habilidad de adaptarse rápida y eficazmente a las necesidades de los clientes con poca penalización en tiempo, esfuerzo, coste o rendimiento.…”
