SAP: Ensamblado a la medida de GM Colmotores

Los sistemas y las tecnologías de información son un elemento vital de las organizaciones exitosas. Por eso constituyen un área esencial de estudio en la administración y dirección de un negocio. Actualmente, la investigación sobre la TI y el desempeño de negocios ha descubierto que cuanto más tenga éxito una empresa para alinear la tecnología de la información con sus objetivos de negocios, mayor será su rentabilidad, y solo una cuarta parte de las empresas logran una alineación entre la TI y los negocios (Luffman, 2003) Esta fuerte tendencia ha tenido un auge interesante en compañías colombianas de todos los tamaños y sectores de la economía; por esta razón hemos buscado abordar una compañía colombiana de talla internacional para describir el proceso de implementación de su sistema de gestión de recursos empresariales (ERP) SAP ECC y su integración dentro de General Motors Colmotores; principalmente con el fin de realizar un análisis del uso que la compañía le está dando a los principales módulos y sub-módulos de contabilidad, ventas y compras de SAP. Este proyecto es muy pertinente especialmente para todos aquellos estudiantes e interesados en el uso y aprovechamiento de los sistemas de información de una compañía, por lo cual se sintetizara la experiencia durante su preparación para la implementación, el desarrollo de la misma y los principales resultados, percibidos por los empleados directamente involucrados, los cuales serán abordados por medio de visitas programadas y entrevistas a profundidad; esto facilitara y permitirá evidenciar de cerca la realidad de la compañía General Motors Colmotores con SAP.

Evolución del sistema de información empresarial SAP en la Universidad Del Rosario

Esta propuesta documenta cómo fue el proceso de implementación de SAP en la Universidad del Rosario (UR). Además permite determinar los factores que la definen cómo una implementación exitosa. En esta investigación no tiene en cuenta la implementación de los sistemas de gestión académica, de recursos humanos o e-learning ya que el estudio solo está centrado en el área administrativa. También se estudia el grado de madurez de los sistemas de información de la Universidad, usando el modelo de Luftam validado en el contexto de las tecnologías. La gran pregunta de investigación es: ¿Cómo fue la implementación de SAP en la UR y cómo esto fue una implementación exitosa?

Implementació dels mòduls SD i MM del sistema SAP R/3 en una empresa del sector metal·lúrgic

SAP R/3 és un software estàndard de gestió empresarial que engloba tots els processos i activitats d’una companyia i permet el disseny de l’aplicació a les necessitats de l’empresa. Diferents avantatges, com ara disposar d’una base de dades única, han fet escollir aquest sistema a una empresa del sector metal·lúrgic com a eina de gestió: Aquest projecte té com a objecte la implantació de dos dels mòduls que inclou el sistema SAP R/3, concretament el mòdul SD (Sales and Distribution), amb el qual es controlen les vendes de l’empresa, i el mòdul MM (Material Management), mòdul amb el qual es controla tot el que fa referència als materials, la gestió d’estocs i tota la gestió de compres de l’empresa

Status and distribution of the Grey-headed Fish-Eagle (Ichthyophaga ichthyaetus) in the Prek Toal Core Area of Tonle Sap Lake, Cambodia

The regional population of the Grey-headed Fish-Eagle (Ichthyophaga ichthyaetus) in Southeast Asia is thought to be in recent decline and its conservation status Linder threat. We undertook a systematic survey in a flooded swamp forest at the Tonle Sap Lake in Cambodia and recorded 32 pairs of eagles in an area of approximately 80 km(2). Three species of water snakes were identified as eagle prey items, previously unrecorded for this species. We suggest that this eagle population has significant regional importance and discuss potential anthropogenic threats to population stability, such as water snake harvesting and construction Of upstream hydropower dams.

Internationalization motives: sell more, buy better, upgrade and escape

Purpose – The purpose of this the paper is to review the motives for internationalization to clarify previous arguments and provide a theory-driven classification. Design/methodology/approach – The authors build on behavioral economics and propose a classification of internationalization motives as the result of the interaction among two dimensions, an economics-driven exploitation of existing resources or exploration of new resources, and a psychology-driven search for better host country conditions or avoidance of poor home country conditions. Findings – These two dimensions result in four internationalization motives: sell more, in which the company exploits existing resources at home and obtains better host country conditions; buy better, in which the company exploits existing resources abroad and avoids poor home country conditions; upgrade, in which the company explores for new resources, and it obtains better host country conditions; and escape, in which the company explores for new resources and avoids poor home country conditions. Originality/value – This theory-driven classification provides predictive power for future analyses of internationalization motives.

An upgrade on the rabbit model of anthracycline-induced cardiomyopathy: shorter protocol, reduced mortality, and higher incidence of overt dilated cardiomyopathy

Current protocols of anthracycline-induced cardiomyopathy in rabbits present with high premature mortality and nephrotoxicity, thus rendering them unsuitable for studies requiring long-term functional evaluation of myocardial function (e.g., stem cell therapy). We compared two previously described protocols to an in-house developed protocol in three groups: Group DOX2 received doxorubicin 2 mg/kg/week (8 weeks); Group DAU3 received daunorubicin 3 mg/kg/week (10 weeks); and Group DAU4 received daunorubicin 4 mg/kg/week (6 weeks). A cohort of rabbits received saline (control). Results of blood tests, cardiac troponin I, echocardiography, and histopathology were analysed. Whilst DOX2 and DAU3 rabbits showed high premature mortality (50% and 33%, resp.), DAU4 rabbits showed 7.6% premature mortality. None of DOX2 rabbits developed overt dilated cardiomyopathy; 66% of DAU3 rabbits developed overt dilated cardiomyopathy and quickly progressed to severe congestive heart failure. Interestingly, 92% of DAU4 rabbits showed overt dilated cardiomyopathy and 67% developed congestive heart failure exhibiting stable disease. DOX2 and DAU3 rabbits showed alterations of renal function, with DAU3 also exhibiting hepatic function compromise. Thus, a shortened protocol of anthracycline-induced cardiomyopathy as in DAU4 group results in high incidence of overt dilated cardiomyopathy, which insidiously progressed to congestive heart failure, associated to reduced systemic compromise and very low premature mortality.

Identification of geodesic chirping Alfven modes and q-factor estimation in hot core tokamak plasmas in ASDEX Upgrade

Alfven eigenmodes (AE) driven by ion cyclotron resonance heating are usually registered by different diagnostic channels in the hot core plasmas of large tokamaks like JET and ASDEX Upgrade. These AE appear very near to the extremum points of Alfven wave continuum, which is modified by the geodesic effect due to poloidal mode coupling. It is shown that the AE spectrum may be explored as the magnetic spectroscopy (like Alfven cascades by Sharapov et al 2001 Phys. Lett. A 289 127) to determine the q-factor minimum and geodesic frequency at the magnetic axis in standard sawtoothed discharges without reversed shear.

Task assignment optimization in SAP Extended WarehouseManagement

Nowadays in the world of mass consumption there is big demand for distributioncenters of bigger size. Managing such a center is a very complex and difficult taskregarding to the different processes and factors in a usual warehouse when we want tominimize the labor costs. Most of the workers’ working time is spent with travelingbetween source and destination points which cause deadheading. Even if a worker knowsthe structure of a warehouse well and because of that he or she can find the shortest pathbetween two points, it is still not guaranteed that there won’t be long traveling timebetween the locations of two consecutive tasks. We need optimal assignments betweentasks and workers.In the scientific literature Generalized Assignment Problem (GAP) is a wellknownproblem which deals with the assignment of m workers to n tasks consideringseveral constraints. The primary purpose of my thesis project was to choose a heuristics(genetic algorithm, tabu search or ant colony optimization) to be implemented into SAPExtended Warehouse Management (SAP EWM) by with task assignment will be moreeffective between tasks and resources.After system analysis I had to realize that due different constraints and businessdemands only 1:1 assingments are allowed in SAP EWM. Because of that I had to use adifferent and simpler approach – instead of the introduced heuristics – which could gainbetter assignments during the test phase in several cases. In the thesis I described indetails what ware the most important questions and problems which emerged during theplanning of my optimized assignment method.

An Upgrade of Network Traffic Recognition System for SIP/VoIP Traffic Recognition

The purpose of this project is to update the tool of Network Traffic Recognition System (NTRS) which is proprietary software of Ericsson AB and Tsinghua University, and to implement the updated tool to finish SIP/VoIP traffic recognition. Basing on the original NTRS, I analyze the traffic recognition principal of NTRS, and redesign the structure and module of the tool according to characteristics of SIP/VoIP traffic, and then finally I program to achieve the upgrade. After the final test with our SIP data trace files in the updated system, a satisfactory result is derived. The result presents that our updated system holds a rate of recognition on a confident level in the SIP session recognition as well as the VoIP call recognition. In the comparison with the software of Wireshark, our updated system has a result which is extremely close to Wireshark’s output, and the working time is much less than Wireshark. In the aspect of practicability, the memory overflow problem is avoided, and the updated system can output the specific information of SIP/VoIP traffic recognition, such as SIP type, SIP state, VoIP state, etc. The upgrade fulfills the demand of this project.
