Market-based coordination of price-responsive demand using Dantzig-Wolfe decomposition method
Energy and AI, 2023 The increasing penetration of Distributed Generation (DG) and Demand Responsive (DR) loads in power systems has necessitated the development of novel approaches to address the coordination problem of Price Responsive Devices (PRD). These PRDs are treated

Direct Method for Solving Bilinear Programming Problem
Наука и техника, 2021 The bilinear programming problem is considered, where a column, which corresponds to one of the variables, is not fixed but can be chosen from a convex set. This problem is known as the Dantzig – Wolfe problem.

Decomposition Strategy for Districts as Renewable Energy Hubs
IEEE Open Access Journal of Power and Energy, 2022 In light of the energy transition, it becomes a widespread solution to decentralize and to decarbonize energy systems. However, limited transformer capacities are a hurdle for large-scale integration of solar energy in the electricity grid.

Research on Cloud Task Scheduling Algorithm with Conflict Constraints Based on Branch-and-Price
Applied Sciences, 2023 The low-energy task scheduling of cloud computing systems is a key issue in the field of cloud computing. Nevertheless, existing works on task scheduling lack consideration of the conflict relationship between tasks and focus on heuristic and other ...

A Three-Stage Optimization Method for Assembly Line Balancing Problem
IEEE Access, 2020 Considering the characteristics of multimodels production pattern on assembly line, the assembly line balancing problem which is non-deterministic polynomial hard becomes more challenging to complete. In this article, we propose a reformulation of simple

The cumulative school bus routing problem: Polynomial‐size formulations
Networks, Volume 82, Issue 4, Page 571-591, December 2023., 2023 Abstract This article introduces the cumulative school bus routing problem, which concerns the transport of students from a school using a fleet of identical buses. The objective of the problem is to select a drop‐off point for each student among potential locations within a certain walking distance and to generate routes such that the sum of arrival ...

Matheuristics: survey and synthesis
International Transactions in Operational Research, Volume 30, Issue 6, Page 2840-2866, November 2023., 2023 Abstract In integer programming and combinatorial optimisation, people use the term matheuristics to refer to methods that are heuristic in nature but draw on concepts from the literature on exact methods. We survey the literature on this topic, with a particular emphasis on matheuristics that yield both primal and dual bounds (i.e., upper and lower ...

A survey on emergent trends in the optimization of car‐sharing systems
International Transactions in Operational Research, Volume 30, Issue 6, Page 2867-2908, November 2023., 2023 Abstract This paper reviews the most recent literature on the optimization of car‐sharing systems. Unlike other surveys, we do not focus on a single aspect of car‐sharing systems, but we consider a wide range of optimization problems with a global view. Our aim is threefold.

Shipping optimization systems (SOS) for tramp: stochastic cargo soft time windows
Journal of Shipping and Trade, 2021 Cargo time windows have been discussed in the shipping literature in several ways and within several contexts. One way considers the hard time windows, where a fixed date is assigned to both the open and close laycan for the cargo loading and discharging
