Best practices methodologies have been used by different companies as competitive growing tools in a globalized market. In Colombia, particularly in the Medellín Metropolitan Area (MMA) and Antioquia's eastern region,; it can be noticed that total productive management (TPM) has been adopted as a competitive support tool. This article evaluates the TPM implementation impact on different competitiveness variables for the companies that are working on it at the AMVA and near easterly regions, finding that there is not a clear relationship between the improvements reached and the main returns, efficiency and even in the results obtained in key business indicators such as overall equipment effectiveness (OEE), failures (breakdowns) and throughput.

Transport is one of the most relevant elements for the competitiveness of companies and cities. An inadequate transportation system generates high costs and low customer service levels, which ultimately produces a negative economic impact for both. This article presents an overview of the technology tools that are part of the Intelligent Transportation Systems (ITS) used to improve the performance and safety of transport, not only of cargo but also of passengers, in different modes such as air, maritime, rail and road. This article begins with a description of ITS, followed by the presentations of their benefits and, finally, it presents a review of the different tools for ITS.

This paper shows fuzzy extended analytical hierarchy (FEAHP) applied to a warehouse management system (WMS) in a Colombian shipyard regarding selecting pertinent logistics software. The FEAHP method has been widely used for resolving decisionmaking problems where many quantitative and qualitative factors and variables are required. However the most important criticism of this method concerns the impossibility of including value judgments not on a continuous scale but rather on a discrete one which can be solved by fuzzy logic. This problem was resolved by using the fuzzy logic extension of the AHP method proposed by Chang in 1996 which was adapted for a specific context regarding a Colombian shipyard.

Worldwide, power generation from fossil fuels is currently in jeopardy due to carbon dioxide emissions that directly influence the greenhouse effect and thus, climate change. This has led to seek or encourage the use of other sources of power generation, such as hydropower. Small Hydroelectric Plants (SHP) represent a suitable alternative for electric power generation in Colombia due to favorable conditions in its operation and the low environmental impact compared with other available energy sources in the country. SHPs, within the Clean Development Mechanism, are considered a source of clean energy with minimal impacts on the environment. This article presents a review of the existing methodologies for assessing greenhouse gas emissions and the implementation of the ACM0002 methodology in a SHP in Colombia, calculating an updated emission factor in the country. The results of this study show the potential for developing SHP projects thanks to the numerous mighty rivers which generate electrical power and contribute to sustainable rural development in Colombia.
