Lagrangian relaxation of the generic materials and operations planning model
The supply chain management requires increasingly proposals for the production programming planning that brings together its special singularities....

Hub location–allocation for combined fixed-wireless and wireline broadband access networks
This paper studies a telecommunications hub location model that includes the classical capacitated facility location problem on a wireline network,...

Mixed-model moving assembly line material placement optimization for a shorter time-dependent worker walking time
Car mass production commonly involves a moving assembly line that mixes several car models. This requires plenty of material supplies at the line...

Multiobjective Optimization of Production Line Supply Based on Maximum Endurance Time and Rest Allowance
The endurance time of a muscle is the time which muscle sustain repeated contractions and it is one of key parameter for estimation of relaxation...

Strong RLT1 bounds from decomposable Lagrangean relaxation for some quadratic 0–1 optimization problems with linear constraints
The Reformulation Linearization Technique (RLT) of Sherali and Adams (Manag Sci 32(10):1274–1290,
1986 ; SIAM J Discrete Math 3(3):411–430,1990 ),... -
Parallel batching with multi-size jobs and incompatible job families
Parallel batch scheduling has many applications in the industrial sector, like in material and chemical treatments, mold manufacturing and so on. The...

Impact of cabotage relaxation in mainland China on the transshipment hub of Hong Kong
Hong Kong has benefited from China’s cabotage rule, as foreign ships loading at a Chinese port can transit to Hong Kong and then call at another...

A decomposition method by interaction prediction for the optimization of maintenance scheduling
Optimizing maintenance scheduling is a major issue to improve the performance of hydropower plants. We study a system of several physical components...

Yard truck retrofitting and deployment for hazardous material transportation in green ports
In the design of green ports, the strategic decision on what types of container transportation equipment are appropriate is extremely important. Yard...

LP-based heuristics for the distinguishing string and substring selection problems
This work aims to evaluate and propose matheuristics for the Distinguishing String Selection Problem (DSSP) and the Distinguishing Substring...
-
Diving Heuristics
Diving heuristics are methods that progressively enlarge a partial solution up to its possible completion, thus ˇjump˘into a solution with no way...
-
Convex Optimization for the Densest Subgraph and Densest Submatrix Problems
We consider the densest k -subgraph problem, which seeks to identify the k -node subgraph of a given input graph with maximum number of edges. This...

Fourth Ventricle Compression (CV4) as a Method for Stress Management
Apart from stressful interpersonal and societal life situations, poorly designed learning environment and lack of knowledge of ergonomics increase...
-
Kernel Search
Kernel search is a purely matheuristic method, which leverages MIP solvers to obtain heuristic, or possibly optimal, solutions of instances encoded...

Legal Framework for Real Estate Investment in China
While the past few years witnessed muted foreign investor activity in Chinese real estate due to governmental restrictions and fierce competitions...

The nested Sinkhorn divergence to learn the nested distance
The nested distance builds on the Wasserstein distance to quantify the difference of stochastic processes, including also the evolution of...

Joint client selection and contract design for a risk-averse commodity broker in a two-echelon supply chain
We study an expected payoff maximization problem for a risk-sensitive broker aiming to evaluate the merits of designing and underwriting an option...
