An exact algorithm for the capacitated facility location problems with single sourcing

Article Abstract:

Research was conducted to examine a special case of the capacitated facility location problem designated Single-Source Capacitated Facility Location wherein each customer can only be supplied using one facility. A new solution approach for the capacitated facility location problem called Lagrangian heuristic is proposed. Results demonstrate that the bounding procedures in the proposed method are efficient. The method along with subgradient optimization present strong lower bounds to the problem.

A method for the cutting stock problem with different qualities

Article Abstract:

The development of a decision support system for minimizing the waste incurred in cutting wood products from wooden boards of different sizes and wood quality is investigated. The problem, which is otherwise known as the cutting problem, is constrained by time limits on the cutting processes. To this end, a mathematical model for characterizing the problem is derived to facilitate a solution using Langrangean relaxation and subgradient optimization.

Integrated defect detection and optimization for cross cutting of wooden boards

Article Abstract:

An integrated approach was developed to enhance cross cut operations that are observed in the secondary wood industry. The approach takes into consideration a need to establish a mathematical model that is effective in gathering information regarding wood cutting. It also takes into account the need to undertake image analysis and optimization within distinct industrial time limits.
