TL;DR: In this article, a mixed integer programming model was proposed to minimize the maximum storage space requirement over an infinite time horizon by offsetting the inventory cycles of items, and a genetic algorithm was developed to find the near-optimal solution.

Abstract: We propose a mixed integer programming model to minimize the maximum storage space requirement over an infinite time horizon by offsetting the inventory cycles of items. We also develop a genetic algorithm to find the near-optimal solution. The mixed integer programming model and the genetic algorithm produce better results than the existing heuristic. We also develop a mixed integer programming model for the finite time horizon; this model is more general and realistic than that for the infinite time horizon. A warehouse management system is designed based on the algorithms we developed.

A systematic literature review on the joint replenishment problem solutions: 2006-2015
Leonardo S. L. Bastos,Matheus Lopes Mendes,Denilson Ricardo de Lucena Nunes,André Cristiano Silva Melo,Mariana Pereira Carneiro +4 more
TL;DR: Among all existing inventory replenishment models, this research was dedicated to the Joint Replenishment Problem (JRP), which consists in the replenishment of inventories in the form of tanks, trucks, and barges.
Offsetting inventory replenishment cycles
TL;DR: The inventory-staggering problem is a multi-item inventory problem in which replenishment cycles are scheduled or offset in order to minimize the maximum inventory level over a given planning horizon and symmetry-breaking constraints are incorporated.

Hybrid genetic algorithm for test bed scheduling problems
TL;DR: In this paper, a hybrid GA was proposed to solve the scheduling problem for a heavy industry company which provides ship engines for shipbuilding companies, and the results show that the hybrid GA performs with an outstanding run-time and small errors in comparison with the integer programming model.

The inventory replenishment planning and staggering problem: a bi-objective approach
TL;DR: This paper is the first one to suggest formulating the inventory replenishment problem as a bi-objective decision problem where, in addition to minimizing the sum of order and inventory holding costs, the authors should minimize the required storage space.

TL;DR: This review indicates that while research on the basic form of the JRP under the original classic assumptions may have slowed, there is much interest in new versions of the problem with relaxed assumptions, including dynamic or stochastic demand.

Computational complexity of uncapacitated multi-echelon production planning problems
TL;DR: In this paper, the authors investigated the computational complexity of the problem for all commonly studied product structures, i.e., the single item, the serial system, the assembly system, one-warehouse-N-retailer system, distribution system, joint replenishment system, and the general production-distribution system.

An efficient optimal solution method for the joint replenishment problem
TL;DR: In this article, an alternative optimal approach based on global optimisation theory is presented, which uses a dynamic Lipschitz constant and generates a solution in little time, and the running time of this procedure grows only linearly in the number of items.

Joint economic procurement—production–delivery policy for multiple items in a single-manufacturer, multiple-retailer system
TL;DR: In this article, an analytical model is proposed to effectively integrate and synchronize the procurement, production and delivery activities in a supply chain consisting of a single raw material supplier, a single manufacturer and multiple retailers.
