A simulation-optimization approach for integrating physical and financial flows in a supply chain under economic uncertainty

open access: yesOperations Research Perspectives, 2023
In the last decade, increasing costs and organizational concerns regarding the funding and allocation of financial resources have led to significant attention being given to financial flow and its effects on planning decisions throughout supply chain ...

New Algorithm to Solve Mixed Integer Quadratically Constrained Quadratic Programming Problems Using Piecewise Linear Approximation

open access: yesMathematics, 2022
Techniques and methods of linear optimization underwent a significant improvement in the 20th century which led to the development of reliable mixed integer linear programming (MILP) solvers. It would be useful if these solvers could handle mixed integer

Exact solution approaches for the workload smoothing in assembly lines

open access: yesEngineering Science and Technology, an International Journal, 2021
In this paper, the problem of minimizing the smoothness index for an assembly line given a fixed cycle time and the number of workstations is studied. This problem which is known as the workload smoothing line balancing problem (WSLBP) is a mixed-integer

Combinatorial Benders' Cuts for Mixed-Integer Linear Programming [PDF]

open access: yesOperations Research, 2006
Mixed-integer programs (MIPs) involving logical implications modeled through big-M coefficients are notoriously among the hardest to solve. In this paper, we propose and analyze computationally an automatic problem reformulation of quite general applicability, aimed at removing the model dependency on the big-M coefficients.
