Relationship between common objective functions, idle time and waiting time in permutation flow shop scheduling
(Elsevier, 2020-09)
This paper focuses on two components of idle time and waiting time, namely core idle time, ∑CITi, and core waiting time, ∑CWTj. Both measures are relevant indicators of the efficiency of production systems, since they are ...

A comparison of machine learning techniques for LNG pumps fault prediction in regasification plants
(Elsevier B.V., 2020)
We present a comparative study on the most popular machine learning methods applied to the challenging problem of Liquefied Natural Gas pumps fault prediction in regasification plants. The proposed solution tries to address ...
Article
The heterogeneous vehicle routing problem with time windows and a limited number of resources
(Elsevier, 2020-09)
This paper introduces the heterogeneous vehicle routing problem with time windows and a limited number of resources (HVRPTW-LR), a practical extension of the classical vehicle routing problem in which routes to be designed ...
Article
Permutation flowshop scheduling with periodic maintenance and makespan objective
(Elsevier, 2020-05)
In this paper, we address the permutation flowshop scheduling problem with cyclical unavailability periods where no operation can be processed. Under this constraint, all machines must stop at the same time due to the shift ...
