Abstract

We study a problem from a real-world application, in which a daily set of orders must be processed following two stages, consisting of preparing perishable products on benches and allocating them to conveyors to be packed in disposable trays. Daily decisions must be made regarding the number and start time of working shifts, the number of workers and their allocation to machines, and the scheduling of orders in a two-stage flexible flow shop environment. The flow shop environment of the studied problem is common in many industries of perishable products, making the problem very general. The problem involves a number of operational constraints, and three objective functions that are minimised in a lexicographic way. To solve the problem, we implement a constructive heuristic and embed it within three metaheuristics: a Random multi-start algorithm (MR), a Biased random key genetic algorithm (BRKGA), and a Variable neighbourhood search (VNS) based one. We perform computational experiments over a set of realistic instances, and present a lower bound obtained from a constraint programming model for the scheduling counterpart. The results of the experiments show that the BRKGA is the most effective in practice for the integrated problem of workforce allocation and scheduling. [ABSTRACT FROM AUTHOR]

25. Programação Linear: Uma Contextualização a partir de Sistemas Lineares.

Author

Simplício de Lyra, Marcelo and Alves de Queiroz, Thiago

Abstract

This paper presents a proposal for the introduction of linear programming in high school considering teaching methods, the teacher and student profiles, and a non-flexibilization of the curriculum. This proposal came as a result of a Stricto Sensu research, which deals with simple problems that encourage high school students to understand Linear Programming by means of a contextualization of studied topics, as resolution of linear equations. The aim is to show to these students the range of real-world problems that can be solved using Linear Programming, with the application of methods to solve systems of linear equations and the support of mathematical softwares. The proposal presented here has not been applied in classrooms yet, but it is expected that students will be able to understand in a contextualized view where linear systems can be applied, the importance of mathematical modeling and the need of to use a mathematical software to solve real big data problems.
