Disruptions in the food supply chain are events that affect the flow of products and can be caused by extreme weather, natural disasters, conflicts, pandemics, and political situations, among others. These events can significantly impact food products' availability, quality, and cost, creating risks to the well-being of local populations and liveli...
There is vast research on particular aspects of warehouse design - layout, material handling, order picking, and operating policies - when, in fact, the decisions involved in the process are interrelated. In this paper, we develop an engineering economics framework for warehouse operations that decomposes the cost structure of the operation and lay...

A production planning problem related to income is addressed in a fruit supply chain of small producers, who prefer not to harvest if the market price does not allow their costs to be recovered. A mathematical model is proposed to represent the harvest decision where three elements are considered: the product perishability, the market prices behavi...
We designed a model for hospital selection and patient transport in the emergency medical system.
The model integrates the criterium of insurance coverage, seldom used in the literature and
the usual criteria such as care capacities, congestion and proximity, typical of countries with mixed
health systems (public-private). In addition, the model co...

In this paper, we provide a method to generate a three-dimensional detailed design of fishbone layouts. This method takes the desired storage capacity and returns the location (x,y,z) of each opening of the warehouse in such a way that the total operational cost - area cost and material handling cost - of the warehouse is minimal. We model the arra...

Lean Manufacturing seeks to eradicate waste. This pursuit is conducted changing many pre-conceptions inherited from the mass production traditions. It is necessary to understand immediate and delayed impacts of the changes, as well as direct and indirect results of these changes. This systemic approach should enhance the learner's understanding of...
Traditional costing systems consider the accumulation of costs, but not their timing. Value stream mapping presents a good picture of the time consumed and operations performed for the production of a product within a manufacturing facility, but it does not track the accumulation of costs. The cost–time profile (CTP) is a tool that follows the accu...

business partners prevents duplicating efforts and allows a company to focus on its core competencies. Hence, collaborating
companies together have the potential to form a strong supply chain. At the individual company level, p...
A Value Stream Map (VSM) allows lean practitioners to visualize the performance and conditions of manufacturing systems. While creating visibility for improvement plans, a measure of overall leanness level is not inherent in the map. This research proposes a methodology to measure the overall leanness of a VSM considering Cost, Time and output Valu...
