Robust Stop-Skipping at the Tactical Planning Stage with Evolutionary Optimization

Tactical Planning of the Oil Supply Chain: Optimization under Uncertainty

The oil industry is increasingly interested in improving the planning of their operations due to the dynamic nature of this business. Decisions made at the oil chain differ in the activity range (spatial integration) and planning horizon (temporal integration). This paper purpose is to address the spatial integration under uncertainty in the oil chain at the tactical planning level and proposes...

How to manage robust tactical planning with an APS (Advanced Planning Systems)

Nowadays, managing correctly the always changing customer demands is a challenge for companies, especially because of its impact on the Supply Chain (Forrester effect). Tactical planning is very useful in establishing robust plans. This paper proposes an alternative policy to traditional practices (frozen horizon ...), the so-called “reference plan”, to obtain more stable and robust production ...

Evolutionary Multi-Objective Robust Optimization

Integrated planning for blood platelet production: a robust optimization approach

Perishability of blood products as well as uncertainty in demand amounts complicate the management of blood supply for blood centers. This paper addresses a mixed-integer linear programming model for blood platelets production planning while integrating the processes of blood collection as well as production/testing, inventory control and distribution. Whole blood-derived production methods for...

The ensemble clustering with maximize diversity using evolutionary optimization algorithms

Data clustering is one of the main steps in data mining, which is responsible for exploring hidden patterns in non-tagged data. Due to the complexity of the problem and the weakness of the basic clustering methods, most studies today are guided by clustering ensemble methods. Diversity in primary results is one of the most important factors that can affect the quality of the final results. Also...
