In this paper the application of the Analytic Hierarchy Process (AHP) is described, and then the service providers cloud computing is identified. The first activity in multicriteria decision- making is to establish the factors that are important to that decision. This has been determined as criteria in selecting cloud providers: accessibility scalability, performance, security. The SEPROCCAHP v01 model has been applied for three groups of students in the course of business logistics. Two groups of students have selected Google, and a third group at Microsoft. The results differ because it depends on value judgments issued in the peer evaluation criteria and alternatives to select.

La elección óptima de equipo en minería superfi cial es una tarea compleja donde intervienen muchas variables técnicas, geométricas y económicas en un ambiente donde existen muchas marcas, modelos y tamaños que compiten por el usuario. El técnico que efectúa la selección no tiene una herramienta apropiada que le permita evaluarlos y decidir por el mejor. La simulación contribuye a efectuar esta selección. En este estudio se desarrolla los modelos determinístico y probabilístico de simulación aplicados a equipos de minado con datos de dos operaciones superfi ciales. En el caso determinístico se simula la producción proyectada de un año de una cantera y en base a costo unitario mínimo se elige la fl ota de equipos tanto en perforación como en acarreo. En la simulación probabilística se usa el lenguaje GPSS para simular modelos de excavación y acarreo para varias comb...

More than a year ago, Ecuador suffered a 7.8 Mw earthquake that was devastating, the automatic response was to run to the affected areas and rebuild. Meche’s House is an alternative: the crisis as an opportunity to experiment and consolidate popular construction systems based on an endogenous and holistic approach. This study evaluates two case studies and their contrasting methodologies in their process of selecting beneficiaries for post-disaster reconstruction: Casa Lista of Mutualista Pichincha and La Casa de Meche, differentiating both cases from analyzing their different approaches: the automatic one, non-reflective and product-based, the other analytical and process-based. Founded on experience and how different processes need different beneficiaries, this study will raise some questions about the effectiveness, pros, cons, and perspectives of different approaches to right...

Within the supply chain, every stage of the logistics process plays a vital role—from the start of production to the delivery of the product to the final customer. However, storage management stands out as one of the most critical phases. Inadequate storage practices or poor SKU control can result in substantial financial losses for a company. This scientific article presents a diagnostic analysis of a logistics operator specializing in the distribution and storage of pharmaceutical products. During the evaluation, several weaknesses were identified in the reception and order picking processes. As a result, various tools were implemented to enhance operational efficiency. The study explored key questions such as: What are the determining factors for selecting a logistics process systematization model? And what are the implications and effects of its implementation? The chosen tools inc...

The incorporation of morphometric data into cladistic analyses poses methodological challenges, particularly in handling continuous characters and landmark configurations in matrices that include multiple individuals per taxon. Although the program TNT (Tree analysis using New Technology) has integrated functionalities for directly analysing continuous and morphogeometric characters, there remains a need for complementary tools that facilitate data preparation and processing. In this context, we present two open-source applications developed in Python: py_tps2tnt and py_tm2tnt. The former transforms TPS files containing multiple individuals per taxon, performs Procrustes alignments, calculates mean configurations, computes centroid size ranges, allows the selection of inter-landmark distances, and exports various types of data into TNT-compatible formats. The latter, py_tm2tnt, focuses o...

We extend the class of M-tests for a unit root analyzed by Perron and Ng (1996) and Ng and Perron (1997) to the case where a change in the trend function is allowed to occur at an unknown time. These tests M(GLS) adopt the GLS detrending approach of Dufour and King (1991) and Elliott, Rothenberg and Stock (1996) (ERS). Following Perron (1989), we consider two models: one allowing for a change in slope and the other for both a change in intercept and slope. We derive the asymptotic distribution of the tests as well as that of the feasible point optimal tests PT(GLS) suggested by ERS. The asymptotic critical values of the tests aretabulated. Also, we compute the non-centrality parameter used for the local GLS detrending that permits the tests to have 50% asymptotic power at that value. We show that the M(GLS) and PT(GLS) tests have an asymptotic power function close to the power envelope. ...

La fabricación de botones para prendas de vestir a partir de las semillas de tagua en el Perú ha sido una actividad poco difundida en los últimos años. Esto conlleva a que la producción por parte de los artesanos y pequeños productores sea baja, ya que no cuentan con maquinaria autónoma que realice múltiples procesos. Además, el costo de estas máquinas autónomas es alta y transportarlo es dificultoso por su peso y tamaño, los artesanos optan por máquinas pequeñas que realizan un proceso en cada ciclo de producción. Los demás procesos se realizan de manera manual apoyándose de herramientas rudimentarias, lo cual es ineficiente. Por ello, en este proyecto se desarrolla un sistema mecatrónico autónomo y modular enfocado en los procesos de selección, agujereado y corte de las tajadas de semillas de tagua para fabricar botones semi acabados para prendas de vestir. Además,...
