Constructive and composite heuristics for the 2-stage assembly scheduling problem with periodic maintenance and makespan objective
(Elsevier, 2022-11-15)
This paper addresses the 2-stage assembly scheduling problem to minimise makespan with availability constraints, where the machines are not always available due to periodic maintenance activities. To the best of our ...

Exploring the benefits of scheduling with advanced and real-time information integration in Industry 4.0: A computational study
(Elsevier, 2022-05)
The technological advances recently brought to the manufacturing arena (collectively known as Industry 4.0) offer huge possibilities to improve decision-making processes in the shop floor by enabling the integration of ...

A method for obtaining the preventive maintenance interval in the absence of failure time data
(Polish Academy of Sciences Branch Lublin, 2022)
One of the ways to reduce greenhouse gas emissions and other polluting gases caused by ships is to improve their maintenance operations through their life cycle. The maintenance manager usually does not modify the preventive ...

A new data-driven framework to select the optimal replenishment strategy in complex supply chains
(Elsevier, 2022)
Motivated by the high variability of markets occurred in the last years, which in turns determined significant uncertainty in lead times and supply chain dynamics, this paper introduces a data-driven framework based on ...

A critical-path based iterated local search for the green permutation flowshop problem
(Elsevier, 2022-07)
The permutation flowshop scheduling problem is a widely studied combinatorial optimization problem with several real-world applications. In this paper we address a green variant of the problem with controllable processing ...

The implications of batching in the bullwhip effect and customer service of closed-loop supply chains
(Elsevier, 2022-02)
Batching is a well-known cause of the bullwhip effect. Despite being very common in many industries to leverage economies of scale, it has been little explored due to its nonlinear complexity. This work examines how ...

The 2-stage Assembly Scheduling Problem
(2022-11-22)
Today, manufacturing systems face new global challenges that require flexibility and quick reactions. To remain competitive, companies must also focus on the minimisation of time, as it leads to cost reductions, shorter ...

Permutation flowshop scheduling problem with total core idle time minimization
(Elsevier, 2022)
In this paper, we present a deterministic permutation flowshop scheduling problem with a new objective function, the total core idle time. The interest of this objective is related to reduce the energy consumption of the ...
