A new efficient genetic algorithm-Taguchi-based approach for multi-period inventory routing problem

Amin Farahbakhsh; Amir Saman Kheirkhah

Volume 12, Issue 4 , December 2023, , Pages 397-413

  The inventory routing problem arises from the combination of the vehicle routing problem and the vendor-managed inventory problem. In this paper, we present a mathematical model and a novel genetic algorithm for solving the multi-period inventory routing problem. The objective is to supply products to ...  Read More

A vibration damping optimization algorithm to solve flexible job shop scheduling problems with reverse flows

Esmaeil Mehdizadeh; Fatemeh Soleimaninia

Volume 12, Issue 4 , December 2023, , Pages 431-449

  The Flexible Job shop Scheduling Problem (FJSP), as a Production Scheduling Problem (PSP), is generally an extension of the Job shop Scheduling Problem (JSP). In this paper, the FJSP with reverse flow consisting of two flows of jobs (direct and reverse) at each stage is studied; the first flow initiates ...  Read More

A mathematical model for robust landing and take-off scheduling at an airport considering runway disturbances

Parviz Tohidi Nasab; Mohsen Vaez Ghasemi; Ghasem Tohidi

Volume 12, Issue 1 , March 2023, , Pages 21-42

  The Aircraft Scheduling Problem (ASP) refers to allocating each aircraft to the optimal take-off and landing time and the appropriate runway. This problem is the allocation of aircraft to the desired runway so that the total damage due to delays or haste in landing or take-off of all aircraft is minimized. ...  Read More

A Genetic Algorithm for Curve Fitting by Spline Regression

Fatemeh Sogandi

Volume 11, Issue 4 , December 2022, , Pages 399-410

  Curve fitting is a computational problem in which we look for a base objective function with a set of data points. Recently, nonparametric regression has received a lot of attention from researchers. Usually, spline functions are used due to the difficulty of the curve fitting. In this regard, the choice ...  Read More

An optimization model for aggregate production planning and control: a genetic algorithm approach

S. M. Ahmed; T. K. Biswas; C. K. Nundy

Volume 8, Issue 3 , September 2019, , Pages 203-224

  In this paper, an optimization model for aggregate planning of multi-product and multi-period production system has been formulated. Due to the involvement of too many stakeholders as well as uncertainties, the aggregate production planning sometimes becomes extremely complex in dealing with all relevant ...  Read More
