Buenas tardes, en primer lugar, quiero agradecer al presidente de la ASI por haber tenido la iniciativa de albergar este foro, al señor rector de la Universidad Tecnológica por haber sido el padre de la idea junto con la Lic. Gallardo de Hernández y a todos ustedes, muy buenas tardes.Me toca a mí el tercer segmento. El Mercosur es una agrupación de Estados, cuatro Estados, que está inserta en el mundo, hecho tan obvio que explica que el Mercosur haya tenido que desarrollar una agenda para su relación externa, para poner las cosas en su contexto.Empiezo por algunas cifras, el comercio ínter Mercosur hasta 1998, representó el 22% del comercio global, el comercio con la Unión Europea es del 28% algo mayor que el comercio ínter Mercosur. Con Estados Unidos existía una cifra muy parecida al comercio ínter Mercosur que es el 21%.Con los países del resto de América Latina el comercio es del 5%, con los países del este del Asia es de 9% y con el resto del mundo del 15%. Esto hace que nos autodefinamos como un grupo de países con determinadas características que enumeró el embajador de Brasil, pero inserto en un mundo con el cual estamos muy vinculados, no puede efectuarse una planificación de actividades prescindiendo del mundo.
Purpose -The purpose of this paper is to propose a methodology (system dynamics-discrete event simulation, SD-DES) to model the SC vulnerabilities and the implementation of IT applications that can improve SC robustness and resilience. Design/methodology/approach -Studies from different and recognised authors are reviewed, compiled and analysed in the follow aspects. First, the behavioural characteristics of SC-IT issues are presented. Second, the potential and pitfalls of SD-DES in addressing these issues are described. Third, the properties that packages of software should have in order to conform to SD-DES philosophy are outlined. Finally, topics for future research are presented. Findings -The behavioural characteristics of SC-IT problems require a new methodology to address this issue which involves both uncertainties and qualitative measures. SD-DES model promises to have this capacity. Therefore, the simulation software should incorporate both continuous process and discrete events. Research limitations/implications -There are few papers about software packages for modelling. Practical implications -This paper sheds light in a hot-topic which embraces both uncertainties and continuous processes. Originality/value -This research gives an innovative way to address disruptive events in the SC and IT integration by means of SD-DES model.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
