Análisis del proceso de reclamos para clientes de la unidad de Negocio de Salón Profesional de Procter & Gamble Latinoamérica

Las decisiones en el mundo empresarial se basan en el supuesto de la existencia de recursos limitados. Sin importar el tamaño de las compañías, existen procesos cruciales que no pueden ser ejecutados dadas limitaciones de personal, activos físicos, financieros entre otros. Por lo anterior, propuestas como las Teoría de las Restricciones (Theory of Constraints - TOC) y el Manejo en base a Actividades (Activity-Based Management – AMB) se han posicionado como un marco de desarrollo dentro de los procesos administrativos y de producción de las compañías. En el presente proyecto se analizará el caso del proceso de reclamos presentados por los clientes en Salón Profesional, una de las Áreas de Negocio de la empresa Procter & Gamble, con el objetivo de formular una alternativa financieramente viable para mejorar el nivel de servicio en la resolución de reclamos para los clientes de Salón Profesional de Latinoamérica.

A perspective on chaos theory: Potential applications to intelligent buildings

Mathematical models have been vitally important in the development of technologies in building engineering. A literature review identifies that linear models are the most widely used building simulation models. The advent of intelligent buildings has added new challenges in the application of the existing models as an intelligent building requires learning and self-adjusting capabilities based on environmental and occupants' factors. It is therefore argued that the linearity is an impropriate basis for any model of either complex building systems or occupant behaviours for control or whatever purpose. Chaos and complexity theory reflects nonlinear dynamic properties of the intelligent systems excised by occupants and environment and has been used widely in modelling various engineering, natural and social systems. It is proposed that chaos and complexity theory be applied to study intelligent buildings. This paper gives a brief description of chaos and complexity theory and presents its current positioning, recent developments in building engineering research and future potential applications to intelligent building studies, which provides a bridge between chaos and complexity theory and intelligent building research.

A study on intelligent building models

Mathematical models devoted to different aspects of building studies and brought about a significant shift in the way we view buildings. From this background a new definition of building has emerged known as intelligent building that requires integration of a variety of computer-based complex systems. Research relevant to intelligent continues to grow at a much faster pace. This paper is a review of different mathematical models described in literature, which make use of different mathematical methodologies, and are intended for intelligent building studies without complex mathematical details. Models are discussed under a wide classification. Mathematical abstract level of the applied models is detailed and integrated with its literature. The goal of this paper is to present a comprehensive account of the achievements and status of mathematical models in intelligent building research. and to suggest future directions in models.

A Multiagent system model which suggests solutions to fuzzy incidents in the field of telecommunications

This article presents the model of a multi-agent system (SMAF), which objectives are the input of fuzzy incidents as the human experts express them with different severities degrees and the further search and suggestion of solutions. The solutions will be later confirm or not by the users. This model was designed, implemented and tested in the telecommunications field, with heterogeneous agents in a cooperative model. In the design, different abstract levels where considered, according to the agents? objectives, their ways to carry it out and the environment in which they act. Each agent is modeled with different spectrum of the knowledge base

Rethinking change:downsizing businesses, changing behaviours and still managing to come out on top

As an indicator of global change and shifting balances of power, every September in Dalian, China, the World Economic Forum meets. The subject in 2011 – Mastering Quality Growth. On the agenda is pursuing new frontiers of growth linked to embracing disruptive innovation. With growth coming from emerging markets, and European and North American economies treading water, many firms in the West are facing the reality of having to not just downsize but actually close manufacturing operations and re-open them elsewhere, where costs are lower, to remain competitive. There are thousands of books on “change management”. Yet very few of these devote much time to downsizing preferring to talk about re-engineering or restructuring. What lessons are available from the past to achieve a positive outcome from what will inevitably be something of a human, as well as an economic, tragedy. The authors reached three fundamental conclusions from their experience and research in facility closure management within Vauxhall, UK: put your people first, make sure you keep running the business and manage your legacy. They devlop the ideas into a new business model linked to the emotions of change.

Effects of coagulation factors and inflammatory cytokines on development of acute myocardial infarction in patients younger than 60 years

Purpose: To investigate the effects of coagulation factors and inflammatory cytokines on acute myocardial infarction (AMI) development in patients younger than 60 years. Methods: In this study, 60 patients admitted to The First Affiliated Hospital of Dalian Medical University (Dalian, China) with AMI and 30 other subjects matched with the patients for age and ethnicity but without AMI were enrolled. Blood samples were collected from the AMI patients and the control subjects after a 12-h fast. Subsequently, the levels of coagulation factors (F) II (FII), VII (FVII), VIII (FVIII), fibrinogen (Fg) and von Willebrand factor (vWF) in plasma were analyzed by enzyme-linked immunosorbent assay (ELISA). The protein expression levels of these coagulation factors were determined by Western blot analysis. Inflammatory factors including C-reactive protein (CRP), tumor necrosis factor-α (TNF-α) and interleukin- 6 (IL-6) were also measured by ELISA. Results: FII, FVII, FVIII, Fg and vWF levels in plasm were significantly higher in AMI patients compared with control subjects (p < 0.01). Furthermore, the protein expression levels of FII, FVII, FVIII, Fg and vWF were also significantly up-regulated in AMI patients compared with those in control subjects. Additionally, no significant difference was observed in CRP between AMI patients and control subjects (p > 0.05). However, TNF-α and IL-6 levels in the plasma of AMI patients were significantly higher than those in control subjects (p < 0.05). Conclusion: The results reveal that the pathogenesis of AMI in patients younger than 60 years might be closely related to the high levels of coagulation factors and inflammatory cytokines in the blood.
