Liquefied natural gas (LNG) is natural gas that has been transformed to liquid form for the purpose of transportation, which is mainly done by specially built LNG vessels travelling from the production site to the consumers. We describe a real-life ship routing and scheduling problem from the LNG business, with both inventory and berth capacity constraints at the liquefaction port. We propose a...

This paper presents a detailed description of a particular class of deterministic single product maritime inventory routing problems (MIRPs), which we call deep-sea MIRPs with inventory tracking at every port. This class involves vessel travel times between ports that are significantly longer than the time spent in port and require inventory levels at all ports to be monitored throughout the pl...

The design of a supply chain has been considered by many practitioners and researchers recently. One model that is used to optimize distribution from a single facility (depot) to a set of retailers over a given planning horizon and considering stock management decisions is known as Inventory Routing Problem (IRP). This model tries to optimize the trade-off between inventory and transportation c...

Abstract The LNG-ADP problem is a tactical planning for creating an annual delivery program (ADP) liquefied natural gas (LNG) producer. An ADP specifies the departure dates of LNG carriers as well at different customers period 12–18 months. can be formulated maritime inventory routing problem, it important requirement to plan deliveries such that levels are kept within minimum and maximum limit...

Setiap perusahaan selalu berusaha dapat memperoleh keuntungan yang besar. Salah satu cara dilakukan oleh adalah menekan biaya dikeluarkan. proses memerlukan besar logistik dan dua per tiga ini berasal dari persediaan transportasi. Permasalahan transportasi pada perspektif supply chain perlu dipertimbangkan bersama agar memberikan hasil optimal. dimodelkan dalam inventory routing problem (IRP). ...
