This research aims to develop a demand forecasting application for Conalca S.A.S., with the purpose of optimizing installed capacity planning in Colombian seaports and enhancing logistical and commercial decision-making. The project arises from the need to implement technological tools that enable demand anticipation, improve operational efficiency, and reduce uncertainty in resource management. To achieve this, the study is based on the comparative application of three mathematical forecasting models—linear regression, weighted moving average, and double exponential smoothing—selected for their ability to capture different time-series behaviors and deliver accurate and reliable results. These models are integrated into a custom computational application designed to automate forecasting processes, facilitate interpretation, and generate visual analytical reports for strategic decision-making. The development of this system seeks to bridge statistical theory with business practice, allowing Conalca to optimize resource utilization, align service capacity with projected demand, and strengthen customer service through validated predictive information. As an outcome, the project aims to enhance operational efficiency, increase organizational competitiveness, and contribute academically to the field of quantitative modeling in port logistics. According to (Chopra & Meindl, 2019), demand forecasting is a cornerstone of supply chain planning, as it enables companies to anticipate resource needs and reduce costs associated with uncertainty. Similarly, (Silver, Pyke, & Peterson, 2016) highlight that appropriate statistical models can significantly improve the accuracy of projections and operational performance. In the Colombian context, (Vidal et al., 2018) emphasize the importance of integrating quantitative methodologies in logistics management as a key factor for efficient project prioritization and execution. In summary, this study represents an applied effort to translate mathematical forecasting techniques into the real context of Colombian port logistics, providing an innovative technological tool that enhances decision-making, operational efficiency, and competitiveness for Conalca S.A.S. in an increasingly complex and uncertain logistics environment.

This applied research project was carried out in a distribution center located in Yumbo, Valle del Cauca, belonging to the agro-industrial sector, specifically in tea production. The order preparation process presents operational inefficiencies due to a mixed storage scheme and item-by-item picking, which results in long travel distances and extended times during the picking process. The main objective of the study was to design picking strategies that improve order preparation, reducing operation times and travel distances within the distribution center. To achieve this, a diagnosis of the current process and a characterization of the distribution center were conducted, complemented by historical demand analysis. Subsequently, strategies were designed based on logistical criteria, and a multi-criteria evaluation was applied using the Analytic Hierarchy Process (AHP) to select the most suitable alternative. As a result, five strategies were defined, based on slotting and picking techniques, integrated with ABC classification, demand frequency, type of collection (by order, batching, by zones), and layout zoning. The evaluation identified the most efficient strategy in terms of reducing order preparation times, minimizing operator travel distances, improving order consolidation, streamlining the product retrieval process, and achieving a more effective organization of the storage system. In conclusion, the study’s findings provide practical solutions to improve the picking process in companies within the agro-industrial sector, contributing to more efficient logistics management and better adaptability to real market demand.

The present degree project addresses the logistic challenge of inefficient management of the distribution centers, a critical problem that directly impacts the productivity and competitiveness of the companies. Specifically, this investigation focuses on the distribution center, of a leading company in the agroindustrial sector, with the objective of designing a slotting strategy that optimizes their operations of receipt, picking and dispatch. The investigation was developed in three methodological phases. Initially, an exhausting diagnosis of the current storage process was done, that revealed the dependence of an manual system based on an Excel file, which generates disorder, inconsistency of data and prolonged times of research. Subsequently, a review of the scientific literature to document the relevant slotting strategies and their application was done. In this phase, it was confirmed that a small percentage of products (Class A) is responsible for most of the volume dispatched, a finding that highlights the importance of applying the Pareto Principle. Based on the diagnosis and review of the literature, three slotting strategies were designed: a hybrid one (ABC + dedicated), one called correlated and clustering, and a third one that integrates ABD, correlation and demand. The results of this project show that the implementation of a structured slotting strategy can increase the operative efficiency and reduce costs. The solution of this proposal not only directly addresses the deficiency of the actual Distribution Center object of study, but also offers a roadmap to optimize the location of the inventory without requiring significant infrastructure changes, guaranteeing picking improvement and a smarter warehouse management.
