TL;DR: The model is formulated in the framework of mixed integer non-linear programming (MINLP), and an exact approach is employed to obtain the optimal solution to reduce the total transportation cost including carbon emission from a heterogeneous fleet with limited capacity.

TL;DR: Imperfect economic production lot size models are considered with time dependent defective rate and solved using Rough age based single- and multi-objective Genetic Algorithms (RMOGAs) to achieve the maximum profit.

TL;DR: The paper outlines the production policies for maximum profit of a firm producing imperfect economic lot size with time-dependent fuzzy defective rate under the respective country’s carbon emission rules and proposes an algorithm for a firm management to achieve the maximum profit.

TL;DR: This study investigates a four-dimensional transportation problem (4DTP) for breakable/damageable items, some of which are pairwise incompatible, with carbon tax policy under crisp and type-2 fuzzy/fuzzy random environments and observes that for minimum total cost, there is a trade off between the total carbon emission and total transportation cost.

TL;DR: In this article, a multi-item, imperfect economic production lot-size (EPL) model with advertisement/promotional cost and selling price dependent demand and partially rework under a budget constraint is considered.
