resumOEste estudo analisa a produção científica internacional em pesquisa operacional aplicada em administração, publicada entre os anos de 1993 a 2013. Em relação aos resultados dos últimos anos, verificou-se um aumento de 1.500% no número de artigos publicados nessa área. A maior participação dos artigos publicados pertence ao continente europeu, com 46,36% das publicações nos últimos vinte anos. A Cadeia de Suprimento, com 9,6%, é o tema que mais atrai o interesse na publicação de artigos. A relevância do tema pode ser verificada pelo seu índice h = 21. Nesse período, foram publicados 176 artigos internacionais em pesquisa operacional aplicada em administração.

Purpose – This paper aims to compare rail and road modes of transport to carry Municipal Solid Waste using a simulation based on the Systems Dynamics of the financial and environmental differences between both. Design/methodology/approach – For modeling, the methodology proposed by Law (2015) based on Systems Dynamics was adopted. As such, the Systems Dynamics methodology helped to map structures for the system developed, seeking to examine its interrelation in a broad context. Through this simulation, the applied dynamics sought to understand how the system in question evolved over time and how changes in its parts affect its behavior. From this understanding, the system could be diagnosed and predicted, in addition to allowing more scenarios to be simulated over time. The time horizon used was eleven years. Findings – The findings show that, as seen from a financial perspective, there is a large difference between road and rail modes of transport to carry MSW. Therefore, it demonstrates the importance of valuing the railroads, in addition to being another option for managers to collect and transport waste generated in the municipalities studied. Originality/value – The model developed can be used by managers in the area of Municipal Solid Waste as a focus to help in the decision-making process to choose logistical options to transport waste. Keywords – Municipal Solid Waste; Modes of Transport; Systems Dynamics; Rail, Road.

This research presents a financial economic analysis of the Agency of Innovation and Technology Transfer (AGITTEC) of the Federal University of Santa Maria (UFSM). With the intention of contributing to the scientific knowledge of the area, this article was built with a research problem defined in verifying how much AGITTEC needs to generate revenue so that it can be self-financed. A research protocol was systematized according to the dynamic systems method consistent with the required methodological rigor. The contribution of this research is linked to a discussion of the favorable results and benefits of the relationship between university and agency, which can extend to improve the competitiveness of companies by presenting a better development. The study served to verify that despite the revenues, There is a heavy dependence of the agency on UFSM resources, and about 90% of its costs and expenses.
