A hybrid genetic algorithm for a dynamic logistics network with multi-commodities and components

Peng-Sheng You, Yi-Chih Hsieh, Hisn-Hung Chen (2011)

RAIRO - Operations Research

Similarity:

Various topics related to reverse logistics have been discussed over the years. Most of them have assumed that facilities are kept open once they are established, and no returned products or recovery parts are stocked in intermediate recycling stations. However, firms may have the right to repeatedly open or close their facilities according to their economic benefits if they can acquire their facilities by lease. It also turns out that intermediate recycling stations like collection...

Mathematical Optimization for the Train Timetabling Problem

Stanojević, Predrag, Marić, Miroslav, Kratica, Jozef, Bojović, Nebojša, Milenković, Miloš (2010)

Mathematica Balkanica New Series

AMS Subj. Classification: 90C57; 90C10; Rail transportation is very rich in terms of problems that can be modelled and solved using mathematical optimization techniques. The train scheduling problem as the most important part of a rail operating policy has a very significant impact on a rail company profit considering the fact that from the quality of a train timetable depends a flow of three most important resources on rail network: cars, locomotives and crews. The train timetabling...

MIP-based heuristics for multi-item capacitated lot-sizing problem with setup times and shortage costs

Nabil Absi, Safia Kedad-Sidhoum (2007)

RAIRO - Operations Research

Similarity:

We address a multi-item capacitated lot-sizing problem with setup times that arises in real-world production planning contexts. Demand cannot be backlogged, but can be totally or partially lost. Safety stock is an objective to reach rather than an industrial constraint to respect. The problem is NP-hard. We propose mixed integer programming heuristics based on a planning horizon decomposition strategy to find a feasible solution. The planning horizon is partitioned into several sub-horizons...
