TL;DR: This paper introduces the first SMP model for serial k-out-of-n systems and develops a new two-phase approach which transforms the problem into a multidimensional multiple-choice knapsack problem (MMKP).

TL;DR: In this paper, the optimal production and pricing strategies for a monopolistic manufacturer who engages in remanufacturing are derived by solving a convex programming model, and the results identify the conditions under which the manufacturer should produce new products or remanufactured products, or both.

TL;DR: A novel integrated non-linear programming formulation of the selective maintenance problem to jointly select the components to be maintained, the maintenance levels to be carried out and the assignment of the maintenance tasks to multiple repairpersons or repair-channels is introduced.

TL;DR: In this article, the conditions of the optimal pricing and production strategies for a monopolistic manufacturer under a non-renewing free replacement warranty for a two-period planning horizon were identified.

TL;DR: In this paper, the authors developed a model for a dual-channel supply chain in which the manufacturer sells new products through a retail channel and also directly through its online channel, and the manufacturer may also sell remanufactured products in its online direct channel if it decides to produce them.
