Split scheduling with uniform setup times
We study a scheduling problem in which jobs may be split into parts, where the parts of a split job may be processed simultaneously on more than one machine. Each part of a job requires a setup time, however, on the ...
Job satisfaction and discrepancies between social and biological timing
(TAYLOR & FRANCIS LTDABINGDON, 2013-08-02)
The discrepancies between social and biological timing are reflected in shift workers' well-being. The aim of this study was to verify the association between job satisfaction and chronotype among day and night nursing ...
Splitting versus setup trade-offs for scheduling to minimize weighted completion time
We study scheduling problems when jobs can be split and a setup is required before processing each part, to minimize the weighted sum of completion times. Using a simple splitting strategy and a reduction to an orders ...

Applying MILP/Heuristic algorithms to automated job-shop scheduling problems in aircraft-part manufacturing
(Universidad Nacional de Santa Catarina, 2013-12)
This work presents efficient algorithms based on Mixed-Integer Linear Programming (MILP) and heuristic strategies for complex job-shop scheduling problems raised in Automated Manufacturing Systems. The aim of this work is ...

Underemployment and Queues for Full Time Jobs: Evidence from Chile
(Universidad de Chile, Facultad de Economía y Negocios, 2016)
This article develops a double selection model in order to test whether part-time workers are excluded from full time jobs (underemployed) or choose to put themselves into distinct labour market segments. Results show ...
Strong LP Formulations for Scheduling Splittable Jobs on Unrelated Machines
We study a natural generalization of the problem of minimizing makespan on unrelated machines in which jobs may be split into parts. The different parts of a job can be (simultaneously) processed on different machines, ...
Jornada de horas reduzidas e equilíbrio trabalho e família no setor bancário.
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-graduação em Engenharia de Produção, 2005-06-22)
With the changes in the work organization and the emergence of the flexible production system, especially from the 80`s, new work arrangements have appeared. One of them is the reduced hours working day in which one works ...
Three Applications on Impact Evaluation
This thesis presents evidence on three applications on impact evaluation. The first one presents robust evidence regarding the impact of computer use in the workplace in Chile during the period 2000-2006. The key contribution ...
