In order to illustrate the concepts discussed and their importance, the authors present a simulation model developed using data from the HVAC sheet metal ductwork supply chain. Conducting experiments on supply chains can be rather costly and time consuming. Therefore, simulation tools can be employed to carry out low cost studies of supply chains.

Four scenarios were studied to evaluate the impact that variations on activity durations and batching have on the project lead time. The conclusions highlight the use of simulation as a tool for supply chain and production system design, the need to improve communication channels between different parts of the supply chain aiming to reduce inventories, and the impact that variability and batching have on the project lead time. Este artigo discute a importância do gerenciamento da cadeia de suprimentos da construção civil bem como conceitos que podem contribuir para a melhoria de seu desempenho. De modo a ilustrar os conceitos discutidos e a sua relevância para o tema, as autoras apresentam um modelo de simulação desenvolvido com base em dados da cadeia de suprimentos de dutos de ar-condicionado. Experimentos com cadeias de suprimentos podem demandar muito tempo e esforço para serem realizados. Dessa forma, a simulação computacional tem grande potencial para o estudo de cadeias de suprimentos, pois pode ser empregada com baixo custo e gerar modelos e conclusões que representem uma realidade controlada na qual experimentos podem ser realizados. Quatro cenários foram simulados para avaliar o impacto que variações nas durações das atividades da cadeia de suprimentos e a definição de grandes lotes têm no tempo de entrega (lead time) de um projeto. Como conclusões, destacam-se o uso de simulação computacional para o projeto de sistemas produtivos e cadeias de suprimentos, a necessidade de melhorar a comunicação entre partes da cadeia como forma de reduzir seus estoques, e o aumento do tempo de entrega do projeto à medida que a variabilidade das durações e o tamanho do lote aumentam.

This paper discusses the importance of managing supply chains in the construction industry as well as concepts that may contribute for the improvement of their performance. In order to illustrate the concepts discussed and their importance, the authors present a simulation model developed using data from the HVAC sheet metal ductwork supply chain. Conducting experiments on supply chains can be rather costly and time consuming. Therefore, simulation tools can be employed to carry out low cost studies of supply chains. Those tools can be used for generating models that mimic a controlled environment in which experiments can be carried out. Four scenarios were studied to evaluate the impact that variations on activity durations and batching have on the project lead time. The conclusions highlight the use of simulation as a tool for supply chain and production system design, the need to improve communication channels between different parts of the supply chain aiming to reduce inventories, and the impact that variability and batching have on the project lead time. |
