Companies commonly allocate their inventories across multiple locations based on their historical sales rates. However, random fluctuations in customer purchases, such as those caused by weather conditions and other external factors, might cause significant deviations from expected demand, leading to excess stock in some locations and stockouts in others. To fix this mismatch, companies often t...

Investigation of feeder ships worldwide has identified South East Asian and the Caribbean as transshipment markets open to feeder ship replacement with a need for improved operational efficiency. In response to this challenge an environmentally sustainable feeder-container ship concept has been developed for the 2020 container market. The concept utilises higher speed and larger capacity than t...

A transshipment problem with demands that exceed network capacity can be solved by sending ow in several waves. How can this be done in the minimum number, T , of waves, and at minimum cost, if costs are piece-wise linear convex functions of the ow? In this paper, we show that this problem can be solved using minfm; logT; log(m U) 1+log(m U) log(mU) g maximum ow computations and one minimum (co...

Abstract Supply and distribution management of blood products is a challenging task due to their short lifespan. The problem even more sophisticated considering uncertain demand for these products. This paper addresses integrated inventory-routing in supply chain network consisting single supplier group centers. Transshipment among centers allowed decrease the cost excess inventory shortage goo...

In industrial engineering, transportation planning, vehicle routing problem, warehousing, inventory management, and customer service are logistics problems. Graph theory algorithms provide solutions to problems such as the shortest path, minimum spanning tree, a company system with branches transfer centers which affiliated, if sorting process is carried out in centers, deliveries collected fro...
