Research Data

A cost tool was created from the mathematical equations and relationships, which determines the costs for the additive manufacturing processes depending on the number and dimensions of the component. Furthermore, weight reductions are specified in percent for known conventional costs that are required to achieve cost parity to the conventional manufacturing method. Therfore, this application allow an easy and fast estimation of suitable additive manufacturing technologies denpending on the selected material, dimension and quantity of a component. With the knowledge of the manufacturing restriction of the each technology this tool deliver a great estimation in finding the right application. It is also possible to adjust the costs and add different machines to this tool, which enables the comparison between technologies.

The dataset contains the experimental data analyzed in the creators' article titled "Bilateral communication in procurement auctions".

The refined dataset consists of edited data from raw AIS data. The data is organised as follows: There is one csv file per cargo ship (271 files in total from 1.csv to 271.csv). This file contains all calls of the respective ship at the Port of Miami for the given period from 2018 to 2020. To anonymize the data, the identifying ship data, i.e. the MMSI, was removed. Further information can be found in the paper in Section 3.1. (paper is under review and will be linked here as soon as available) The raw AIS data which are used are available on the websites of the National Oceanic and Atmospheric Administration (NOAA) Office for Coastal Management.
