It is important for small growing textile companies to make key decisions based on accurate and reliable information about the present production process and how future changes could affect them. Using traditional mathematical methods it is not possible to accurately and reliably reflect the real stochastic behaviour of processes and activities carried out in this industry. There are, however, information technologies such as the computer simulation technique that allow such information to be obtained taking this behaviour into account.he research carried out a simulation study of the garment making process of a small textile company in order to propose a better distribution of resources by experimenting with a simulation model of the process, In addition, some of the quantitative information obtained with this technique is presented. The results obtained show that making changes in assi...

In this investigation it has been evaluated the current situation of the emergency area that assists adults, in a public hospital of Peru. The software Arena was used to perform discreet simulations, with the objective of obtaining improvement proposals that allow reduce the total time of the patient’s permanency in this area before he is to discharge from hospital or admitted in the hospital. A simulation model was developed where several types of patients were identified that were assisted in the surgery, medicine, and traumatología topics. In some cases clinical analysis was required. For reduce the time of a patient’s permanency in the system diverse possibilities were evaluated, being the best alternative a modification in the schedule of the doctors’ attention in the medicine topic. This solution considers that four doctors assist from 7:00 a.m. to 7:00 p.m. and two doctors ...

Currently, textile processing plants need to control the conditions associated with the spinning process, being the air conditioning of working environments an important factor in the quality and productivity of these processes. The benefits obtained from the optimization of this air conditioning help to guide a lower energy consumption, helping to improve the positioning of the products and providing profitability in the operation processes. Due to the advantages obtained in the air conditioning process, this work proposes a system that allows reusing the residual energy generated at the outlet of the ventilation ducts. This residual energy is fed into the plant to reduce the high temperatures observed in the ceiling. Consequently, this approach will generate a decrease in the service demand of the air conditioning system and reduce operating costs. Also, to verify this proposal, a mult...

Globalization has intensified competition in many markets. To remain competitive, the companies look for satisfying the needs of customers by meeting market requirements. In this context, Process Capability Indices (PCI) play a crucial role in assessing the quality of processes. In the case of non-normal data there are two general approaches based on transformations (Box-Cox and Johnson Transformation) and Percentiles (Pearson’s and Burr’s Distribution Systems). However, previous studies on the comparison of these methods show different conclusions, and thus arises the need to clarify the differences between these methods to implement a proper estimation of these indices. In this paper, a simulation study is made in order to compare the above methods and to propose an appropriate methodology for estimating the PCI in non-normal data. Furthermore, it is concluded that the best method ...

Over the last years, using phenomena models in interpreting and designing of software in metallurgical processes has been increasing. In this present research, a series of experimental test with polymetallic minerals is shown, which have been submitted to Flotation, Filtration, Leaching and Sedimentation processes. Mathematic modelling of such processes is shown, as well as the processing and simulation of the experimental data through the respective models. It is intended to contrast them with data from metallurgical plants for their respective validations. All these results will be used for a better planning and control of industrial variables in a concentrating plant.

This paper presents an investigation of the extraction of essential oils by steam distillation. The process is analyzed and a model is developed for the extraction of essential oil of eucalyptus in pilot scale with a steam flow of 5.73 g / min. According to the model Dunckhorst-Houghton, which considers the effect of axial dispersion, and the use of optimization procedures to establish the model parameters, excellent agreement was obtained between the amount of oil extracted theoretical and experimental.

In this article, a simulation model was developed to propose and evaluate improvements that increase the productivity of the production process of a manufacturing company and at the same time help achieve the company's objectives, for which the Promodel simulation software was used. The study begins with the conceptualization of the model explaining the operation of the production process of the company, detailing the transactions used in the operations and then presenting the layout of the model with the different locations, entities and resources provided by the production process. And finally the results of the model are transcribed with the new values of the variables that intervene in the process and with these values compare it with the current ones and obtain the conclusions of productivity improvement.

Se tiene por entendida a la simulación como una herramienta científica que genera diversos contextos a los cuales se puede ver incluida a la empresa, mejorando los cuellos botella de la empresa, tiempo ciclo o costos elevados, con la finalidad de mejorar por ejemplo la productividad, eficiencia o rentabilidad. En base a ello para el presente trabajo de investigación se toma como objeto de estudio a la línea de producción de pollos frescos y limpios de la empresa avícola “Fénix SAC” la cual opera de manera ineficiente debido a que se registran problemas en los puestos de trabajo tanto físicos, como de ruido, iluminación, termomagnético y disergonómico. Para esto se ha buscado realizar propuestas de mejora que conlleven a incrementar la productividad en la empresa mediante la simulación de procesos. Específicamente hablando, se desarrolló un diagnóstico del proceso produ...

Thermodynamic simulation models have been developed to observe the behavior of the minor elements Zn, Pb, As, Sb and Bi; as well as the major elements Cu, Fe, Si, 0 and S in the conversion and fusion processes: NORANDA and ISASMELT for the production of copper-rich mattes. The Noranda process shows a steady state model for obtaining a high-grade matte in metallic copper. The lsasmelt process is based on the concept of the two independent reaction sites in the bath (slag-killing interface): rapid oxidation and slow reduction. The heat balance of the process and the distribution thermodynamics of the minor elements are united and expressed in terms of the process variables such as temperature, enriched 02, composition of the charge, degree of matte and content of the magnetite in the Slag and other variables are incorporated into the modeling, which can predict the operating effects of che...

The implementation of any software development process involves the consumption of critical resources. Software engineers cannot experiment with different development processes before starting them in real projects, due to the time that would entail and the amount of elements that are involved, so it is vital to have tools that allow the pre-visualization of the results of executing the software development process and how the environmental variables affect it, thus being able to anticipate under what conditions the software development process will be deployed. This paper presents the modelling and simulation of a software development process using System Dynamics (SD), which allows the graphical representation of the elements intervening in the software process, and the incorporation of as many relevant elements as possible. As a software costs estimation reference, the COCOMO estimati...
