MODELO QUE IDENTIFICA LA MADUREZ DE LOS PROCESOS. CASO: PEQUEÑA EMPRESA MANUFACTURERA.

The high competitiveness in existing markets and the patterns imposed by the globalization amplify the uncertainty of the immediate future of small businesses in Mexico: that is magnified because the capabilities of meeting the expectations of sector, which is dynamic and changing, are ambiguous, caused by unfamiliarity with the maturity level of their internal processes and the ability to respond to the various subsystems in the firm. The work proposes a model that analyzes and identifies the maturity level of 5 small manufacturing business that have exceeded the threshold of disappearance, which is between 4-5 years and represents 70% of them.

EVALUACIÓN ECONÓMICA Y AMBIENTAL DE DISEÑOS ESTRUCTURALES DE EDIFICACIONES MEDIANTE ANÁLISIS DE CICLO DE VIDA BASADO EN ENTRADAS Y SALIDAS

Esta investigacion examina la aplicacion del modelo IO-ACV (Analisis de Ciclo de Vida basado en Entradas y Salidas) para evaluar opciones de diseno estructural que tengan formas rectangulares, cinco niveles de altura y sean de uso habitacional. El estudio se enfoco a los materiales estructurales mas comunes en la vivienda de interes social de la zona central de Mexico: concreto, acero de refuerzo y madera de cimbra. El ACV convencional o por procesos requiere datos que en entornos como el caso de Mexico son dificiles de obtener. El IO-ACV es una alternativa para evaluar un producto desde el punto de vista ambiental ya que solo requiere datos de las transacciones que se realizan entre los sectores economicos involucrados en el ciclo de vida del producto. No obstante que dicho modelo esta disenado para un contexto industrial como el de los Estados Unidos o Europa, se puede obtener una evaluacion ambiental aproximada al ACV convencional o tambien denominada por procesos. Este articulo analiza las diferencias en las estimaciones que se pueden obtener con el modelo IO-ACV y tomando como referencia el ACV por procesos. Se presenta una propuesta para usarlos de manera complementaria en dos fases: la primera, una evaluacion amplia o general basada en el metodo EIO-LCA, el cual se basa en el modelo IO-ACV y la segunda, una evaluacion detallada basada en el ACV de los materiales y el transporte. La propuesta fue aplicada en la evaluacion de cuatro disenos estructurales en la zona central de Mexico y las variaciones en las estimaciones con el modelo IO-ACV permiten darle utilidad en el contexto de Mexico.

Modelos de simulación aplicados a la planificación de sistemas de producción no-confiables

ABSTRACT: This work discusses the obtained results in the article of Rivera-Gomez et al. [1], that deals with the production control problem of an unreliable manufacturing system subject to random failures and repairs. The main objective of the study is the assessment of the ARENA simulation software at reproducing accurately the dynamics and the stochastic behavior of an unreliable manufacturing system. Three simulation models were developed, based on concepts of discrete and continuous simulation. The simulation results are validated with an analytical solution and a comparison of the models is conducted in terms of accuracy and time economy. The obtained results show that the continuous simulation model with C++ inserts outperforms the rest of the models. The results of the study can be extended to real cases in industries with complex systems. Keywords: modeling methodologies, manufacturing system, discrete simulation, continuous simulation, optimal control.

A MODEL FOR CONCEPTUALIZING THE KNOWLEDGE IN SUPPLY CHAIN RELATIONSHIPS. CASE STUDY: MANUFACTURING SMEs IN THE

This study aimed to identify the various financial crises by knowing their causes and effects and then figuring out the solutions to the crises which the postural economy posed. Therefore, this hassled to the claims by Islamic economics solutions, where by the researcher uses the descriptive method that describes the problem in question to achieve its objectives. This was attained through the study of documents, books and research related to the study to show the theoretical background of the financial crises. In the light of this, the researcher concluded on a number of important results that the postural economy is based on al gharar (buying something without knowing the result of the bargain, such as selling fish in the sea, birds in the air), and usury which is forbidden in the Islamic economy. In addition, Islamic religion forbids the abuse of peoples wealth unlawfully, but calls for all kinds of investment based on profits gained by the loss base.Korca District is situated in southeastern Albania, in the Central Mountainous Region. Economically speaking, Korca used to be one of the most important centers in the region, in which trade of agricultural products with other countries took place. The main sectors of business include the agro-business sector, garments and tourism. Korca ranks second nationwide in terms of the size of the agricultural land, which makes agriculture the most important sector of its economy. Agricultural products account for 32 percent of all revenues. Great prospects are in store for the small and medium agro-business enterprises and consequently, for the size and relevance of the agricultural sector in the Korca District. During the last years the production of fruit tree has intensified greatly and this has put the farmers in front of new challenges for their activity. In this respect marketing has acquired a great emphasis, whose role is becoming even more important. This material aims to analyze some of the alternative marketing which can be used to gain a competitive advantage. The methodology of the study includes gathering secondary data and the study of literature in this field. The study ends with giving some conclusions to all the partners in the marketing channel in order to create a long-term relationship and survival in the competition.
