An exact approach for cyclic inbound inventory routing in a level production system

Optimization methods for combined problems in transportation and logistics management

“…The higher optimality gaps and the great number of unsolved instances underline the difficulty of solving the periodic variant with limited vehicle fleet, especially for larger instances. Our findings are in agreement with the observation of Bertazzi et al (2020) on the difference between the classic IRP and a cyclic IRP variant which requires equal starting and end day inventories. The authors conclude that the cyclic approach is significantly more difficult to solve than the classic one.…”

“…This operational scenario occurs in liner shipping (feeder ships that service inland ports along a stream) and facility logistics (tow trains thT deliver part bins to the stations of an assembly line). More recently, Bertazzi et al (2020) study a problem where components are collected from a set of supplier locations and delivered to a manufacturing plant. The collection plans are cyclic and thus repeatable.…”

A solution algorithm for integrated production-inventory-routing of perishable goods with transshipment and uncertain demand

“…Most previous studies on production and distribution management were conducted with non-perishable items [2,15]. However, recently, researchers have become more interested in studying the production and distribution management of perishable goods due to the complexity inherent in the problem [16].…”

“…by the vehicle and constraint (14) shows that the amount of product delivered to the blood center should be within its available capacity. Constraint (15) denotes the limited capacity of the vehicle. Constraint ( 16) constructs the tours and constraints ( 17) and ( 18) are the sub-tour elimination constraints.…”

Time-Dependent Travel-Time Constrained Inventory Routing Problem

“…The scheduling is done in a smaller time interval and is reproduced over and over. A work in this context is presented in [3]. Multi-echelon IRP: For a globally optimised network, the IRP can be studied in a multi-echelon environment where multiple layers of the supply chain are included: a supplier, retailers and clients.…”
