This paper studies periodic review inventory systems in which replenishments are capacitated. This capacity restriction implies that the order-up-to level may not always be reached at each replenishment, such that additional safety stock is needed to achieve the same service level as in the...

In this paper, we deal with the sequencing and routing problem of order pickers in conventional multi-parallel-aisle warehouse systems. For this NP-hard Steiner Travelling Salesman Problem, exact algorithms only exist for warehouses with at most three cross aisles. We propose a new approach in...

Given the increasing pressure to improve the efficiency of container terminals, a lot of research efforts have been devoted to optimizing container terminal operations. Most papers deal with either the Berth Allocation Problem (BAP) or the (Quay) Crane Assignment Problem (CAP). In the...

This papers considers the allocation of cargoes to tanks for the specific case of chemical liquid bulk vessels. No articles in the literature and no commercial software packages are available that can handle the multitude of side constraints that need to be considered. These constraints include...

The single-vehicle cyclic inventory routing problem (SV-CIRP) consists of a repetitive distribution of a product from a single depot to a selected subset of customers. For each customer, selected for replenishments, the supplier collects a corresponding fixed reward. The objective is to...

This study examines why no existing decentralized storage is suitable for storing personal data, from a legal and ethical point of view, and what negative consequences the development of blockchain technologies may have for society without taking this crucial factor into account.We take a closer...

The article offers a methodology for selecting economic tools to coordinate federal, corporate and regional interests in the process of selecting a route for the “Eastern Siberia – the Pacific Ocean” oil pipeline. The building of the oil pipeline is regarded as an integrated...

Due to the higher workload it produces, reducing the size of operational teams in the chemical process industry can have a negative effect on the ability to control abnormal situations, fatigue, etc. A lack of qualified operational personnel in unusual conditions and the resulting lack of...
