Mine equipment selection is a complex task due to numerous technical, geometrical and economical variables involved. The variety of equipment manufacturers and agents carrying different models, types and sizes make the selection procedure even more complex. The mine planner does not have a tool to correctly select the equipment or fl eet for a project. Simulation fi lls the gap and contributes to this goal. This study tries to apply deterministic and probabilistic simulation approaches in selecting mining equipment using fi eld data from two surface mine operations. The deterministic model uses a one year production plan from a quarry. The equipment fl eet is selected on the basis of minimum unit cost for both drilling and excavation-haulage equipment fl eets. For the probabilistic approach the GPSS language is applied. Programs were prepared for various combinations of loaders and haule...

The purpose of this research is to reduce the duration of processes and waiting times in the customer service modules of an educational institution. For this purpose, the use of the Lean Manufacturing methodology is proposed, following the framework formulated by the DMAIC sequence proposed by Lean Six Sigma, which consists of five consecutive stages: define, measure, analyze, improve and control; In each of them, the description, techniques, instruments, and validation are presented. Through an unstructured interview with customer service personnel and administrative staff, information was gathered to build a simulation model of the initial situation in the Arena 15.1 software. Then, three improvement alternatives were designed, and their results were compared with the original scenario, and it was concluded that the standardization of subprocesses and the hiring of additional personnel...

In the multivariate analysis of capacity there are many aspects, not even resolved yet, around some indexes such as the non-normality of the data and if the variables of quality are correlated or not. In this work we intend to propose the development of a multivariate capacity index (ICPM, for its acronym in Spanish) that works for both previous cases through simulated data examples. It is worth mentioning that we find a wide performance of the proposed index in comparison with other similar capacity indexes.

Potential risks associated with the cuttings re-injection process as an alternative method for drilling wastes disposal were identi- fied and assessed in two offshore platforms located at the southwest of the Campeche Sonda in Mexico. Risks were evaluated using the HAZOP methodology, to identifying hazards in 11 nodes. In addition, deviations in the process were analyzed, and each risk analyzed was categorized as tolerable or non-tolerable and providing some recommendations. Consequences derived from accidental spills of slurry and/or cuttings were analyzed using the mathematical model YAXUM 3D to simulate the pollu- tants dispersion in seawater in three different climatic periods. The results of the consequences analysis shows that even the concentrations in the discharge point exceeded the recommended criteria for protection of the marine life and seawater quality, the spill is rapidly...

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...

El aumento en la complejidad de los sistemas automatizados requiere que las metodologías de programación de PLC no se queden en el enfoque tradicional, el cual es un método heurístico de prueba y error. A pesar de que este procedimiento es el más empleado en la industria, este presenta dificultades en cuanto a la representación de ocurrencias, sincronización y la posibilidad de validar el programa antes de implementarlo en los controladores industriales (PLC). Este proyecto propone el uso de Redes de Petri como una herramienta para programar un PLC que controla un modelo digital de un sistema automatizado que clasifica, ensambla y transporta piezas. La metodología del proyecto consiste en: (i) una revisión de la literatura sobre Redes de Petri aplicada en el control de procesos, (ii) la construcción del modelo digital en Factory I/O, (iii) el modelado y especificación de la pl...

El pisco es una bebida alcohólica tradicional del Perú cuya producción artesanal sigue métodos empíricos, generando variabilidad en la calidad y el rendimiento. Durante la destilación el destilado se separa en tres fracciones —cabeza, cuerpo y cola— definidas por cortes que influyen en la presencia de compuestos no deseados y en el cumplimiento normativo. Este estudio desarrolla un modelo matemático de la destilación batch de un mosto fermentado compuesto por etanol-metanol-agua-acetaldehído en un alambique de cobre, integrando balances de materia y energía, ecuaciones de equilibrio líquido–vapor mediante UNIFAC y correlaciones de transferencia de calor. Las simulaciones en MATLAB consideraron tres niveles de composición inicial de compuestos volátiles (bajo, intermedio y alto) y evaluaron el impacto del corte de cabeza sobre la composición del destilado. Los resultad...

En muchas ocasiones el investigador necesita de técnicas para extraer información o conocer la estructura de los datos y métodos de visualización para el conocimiento parcial o total del proceso subyacente que los generó. En esta tesis se desarrollan nuevas técnicas y algoritmos para el análisis exploratorio y reducción de datos multidimensionales utilizándose como base el análisis tensorial, así como también se propone una nueva técnica de simulación de datos provenientes de una distribución normal multivariante, utilizando el proceso inverso de la técnica de las Componentes Principales. Entre las técnicas desarrolladas están el Diagrama de Rosa, Diagrama Circular 3D, Proyecciones sobre Superficies Cilíndricas y Esféricas, entre otras. También algunas de estas nuevas técnicas propuestas se basaron en la Projection Pursuit desarrollada por Friedman y Tukey en el añ...

The infiltration is one of the hydrological processes that receives a lot of importance in the environmental engineering and of water resources, per decades many investigators have come doing efforts to model the process of infiltration, departing from the equation of Richards (1931). The behavior of the infiltration can be treated in form three dimensional and time in its most complex, and depending on what is required even in its one-dimensional form most the temporal component. In this work Richards's equation diminishes to his expression unidimensional, more his temporary component and is solved under the method of finite differences using Crank-Nicolson's, scheme in an implicit alternate exact scheme, in the second order both in space and in time. The above mentioned scheme was codified in MATLAB, and the results fulfill satisfactorily the aim to predict the movement of the water in...

Half way structured problems are those that have elements or relations than sometime they are out of control. But always they prove to be difficult in a time of presenting solution alternatives without the benefit of a methodology in order to such end designed. At the present time there are methodologies that they allow us to discuss these problems and to define its structure to what later we can understand its behaviour. That’s why this argument that we make use in this study to discuss the problem that at present rice sower show us in the region and the country, where we made use of a methodology that is not new in his appearing, but even well, in his application in our midway, I mean specifically to the Dynamic of System, as a methodology to study complex systems, and proposing solutions alternatives The activity ric e sower in her Region San Martin and the country always has been i...

The importance of service level in companies is increasingly vital, whether post or pre- sales, the level should always aim to satisfy the customer. To maintain a good level of service it is necessary that, in each sector, logistics and transportation are reviewed to meet the delivery time agreed with the customer, this avoids a decrease in the customer base and even sales cancellations that affect the final profit. Therefore, it is essential to plan the supply and distribution processes and then review the operation times to seek a standardized process. The proposed proposal uses a Master Plan Schedule (MPS) and Distribution Requirement Planning (DRP) tools to improve supply and distribution management. In another way, the use of Poka Yoke and Work Standardization is also proposed to avoid errors to reduce operating times and seek their standardization. After the implementation of the p...
