Evaluating the Supply Chain Design of Fresh Food on Food Security and Logistics

The fresh fruit and vegetables sector is competitive and dynamic, with uncertainties related to supply and quality. These uncertainties generate challenges in food safety and food security issues for developing countries. Researchers have studied the supply chains (SCs) of perishable products from different perspectives of modeling. However, there are few studies that contemplate the dynamics and Supply Chain Design (SCD). This paper present a model based on system dynamics for SCs of fresh foods. The model evaluates different SCD and their impact on food security and logistics. Unlike the studies found in the literature, the model includes the loss derived from the life cycle of the food and from logistic operations. From the application of the model to three SCs of fresh fruits in Colombia, it was found that a combination of the design structures is required to achieve performance measures for food security and performance of logistics.

System for Improving Productivity Using the Techniques of 5’S

In a lean manufacturing environment there are lot techniques, methodologies and philosophies been applied. One of the most important is the 5’S, that is focused to improve the work site order for mechanical tools, keep a clean work site, standardized work among others, that are important for a good maintenance program. This chapter is focused to describe a 5’S program, the implementation process, and illustrates an example that was applied to an industry in Colombia. The chapter finalize discussing results and proposing some task for an effective implementation.
