El transporte ferroviario tiene un rol importante y creciente en muchos países,
lo cual crea la necesidad de optimizar el uso de la infraestructura ferroviaria y
los métodos y herramientas para su administración. La ...
[EN] Fast-tracking a project involves carrying out sequential activities in parallel, partially overriding their original order of precedence, to reduce the overall project duration. The current predominant mathematical ...
[EN] Production planning, scheduling and sequencing comprise the core of the manufacturing companies' perfor-mance. The new and changing market demands make manufacturing a challenge because companies must produce by using ...
[EN] In this paper we analyze a parallel machine scheduling problem in which the processing of jobs on the machines requires a number of units of a scarce resource. This number depends both on the job and on the machine. ...
The permutation flowshop scheduling problem has been thoroughly studied in recent decades, both from single objective as well as from multi-objective perspectives. To the best of our knowledge, little has been done regarding ...

[EN] One of the problems when conducting research in mathematical programming models for operations planning is having an adequate database of experiments that can be used to verify advances and developments with enough ...
Rodríguez Molins, Mario(Universitat Politècnica de València, 2015-03-31)
Despite the continuous evolution in computers and information technology, real-world
combinatorial optimization problems are NP-problems, in particular in the domain of
planning and scheduling. Thus, although exact ...
[EN] In this paper, a new mathematical programming model is proposed for a partial flexible job shop scheduling problem with an integrated solution approach. The purpose of this model is the assignment of production ...

[EN] Nowadays, high performance multicore processors implement
multithreading capabilities. The processes running concurrently on these
processors are continuously competing for the shared resources, not only among
cores, ...
[EN] In Schedule Risk Analysis (SRA), activity sensitivity metrics measure the importance of activities in a project schedule. Highly sensitive activities are those more likely to increase project duration variability ...
Ripoll Ripoll, José Ismael; Ballester-Ripoll, Rafael(Institute of Electrical and Electronics Engineers (IEEE), 2013-09)
Task period selection is often used to adjust the workload to the available computational resources. In this paper, we propose a model where each selected period is not restricted to be a natural number, but can be any ...
