An Overview of Operations Research / Management Science in Latin America -- Collaborative versus Non-Collaborative Bus School Routing -- Method for Assigning Break Times in Predefined Shifts for Call Center Teleoperators -- Financial Risk Analysis for a Specialized Dairy Farm Project and Impacts...

Free-floating and instant-access carsharing systems are two features of the most flexible carsharing systems. In the former, users are allowed to freely park the car in any legal parking spot within the boundaries defined by the service operator. In the latter, users are not requested to make...

RESUMEN: Este artículo trata sobre la programación de la producción agraria, entendida no sólo como la selección entre varios cultivos sino, también, como la distribución temporal de los mismos. Primero se estudia la programación de la producción para una empresa, donde sus decisiones...

Mathematical programming-based systems analysis is used to examine the consequences of alternative operation configuration for the agricultural operations within the Texas Department of Criminal Justice. Continuation versus elimination of the total operation as well as individual operating...

In this paper, we propose a location model for the optimal organization of transplant system. Instead of simulation approach, which is typical when facing many health care applications, our approach is distinctively based on a mathematical programming formulation of the relevant problem. In...

Preparing a schedule for physicians in the emergency room is a complex task, which requires taking into account a large number of (often conflicting) rules, related to various aspects: limits on the number of consecutive shifts or weekly hours, special rules for night shifts and weekends,...

This paper deals with the mathematical analysis of product-process chains, aimed at the proper design of recycling systems. A modelling method is presented that can be applied to various chains. It is applied to a case in which a producer of sophisticated packaging tools requires insight into...

In Honduras, traditional coffee processing is the cause of two major problems: poor coffee quality and contaminated water. In this paper we present a method that determines the trade-off between economic efficiency and contamination in a Honduran sub-watershed. The method is a bioeconomic model...

Policies to mitigate greenhouse gas emissions are likely to increase energy prices. Higher energy prices raise farmer costs for diesel and other fuels, irrigation water, farm chemicals, and grain drying. Simultaneously, renewable energy options become more attractive to agricultural producers....

Mathematical programming results revealed that moving toward more flexible agricultural policies would generate substantial economic and environmental gains in a North Carolina diversified cropping region. But in a Washington-Idaho dryland grains region, only the use of relatively new and...
