Modelo de gestión logística para pequeñas y medianas empresas en México

Abstract

The market opening and the globalization of supply chains, demand a structural changes in which logistics has a strategic role. Nowadays, clients evaluate product quality, its value added and its availability in time and form, which implies a need to make the process efficient. Several experts have proposed some logistics management models to increase competitiveness in the market, but some of these models are too ambitious for small and medium sized enterprises (SMEs) due to their informal structure and their lack of technical knowledge; other models make indirect reference to the internal information flows, which include whole system disintegration because of the weak interrelation among the different areas. In Mexico, SMEs represent 4.2%, they generate 31.5% of employment and provide 37% of the gross domestic product; that is why it is important to reinforce their competitive position in the market. This research presents the design of a conceptual model of logistic management for SMEs which could provide comprehensive solution through control of the variables involved in the logistics process; to verify that the variables considered in each identified dimension are correct factor analysis was used.

A Fuzzy Expert System for the Integration of Collaborative Supply Chains

“…With these results, the questionnaire was restructured and modifications were made to the proposed ISC model [46].…”

“…Values greater than 0.6 in KMO and less than 0.05 in Bartlett justify performing a factor analysis [46]. Having analysed the results, it could be concluded that the factor analysis could be properly applied.…”

“…When applying a factor analysis, the principal components method can be used because the objective is to condense most of the original information into a number of factors for prediction purposes. The factors to extract are those that have auto-values greater than 1 [46]. The 18 variables of the designed instrument were analysed, obtaining the results shown in Table 4, where it can be observed that two factors obtain values greater than 1.…”

“…To determine whether question P03 could be removed from the questionnaire, its information was excluded and the extraction process was repeated. The results (Table 6) showed load levels greater than 0.71 for every factor considered excessive [46]; for this reason, we determined to use all the questions (except for P03, which was eliminated) to feed the designed ISC model.…”

“…A pesar de que la Pyme tiene importancia en el nivel internacional y nacional, en general, carece de una estructura formal en la mayoría de sus áreas [6], [7]. Debido a su tamaño y la escasez de recursos económicos es común que los empleados realicen varias actividades para muchas de las cuales no son especialistas; suele observarse que las mismas personas que dirigen sean quienes también ejecuten funciones de planeación financiera, producción, administración de personal y comercialización, entre otras [8].…”
