Facility Location Problem FLP / Logistics distribution network design

The presented data are the typical parameters of logistics distribution network design mathematical models.
The data are organized in accordance with the list of model’s parameters (file: Logistics distribution network design problem - description - Redmer_A.pdf) attached to the data set (file: Logistics distribution network design problem - data set - Redmer_A.txt).
The data are a real life data gathered in a Polish company being a general merchandise (FMCG) retailer, running almost 200 medium-size shops covering 70% of the Polish territory.
The average shop has the trade area of 500 m2 and sales about 7 thousand different products (SKUs). The company employs more than 5 thousand workers, operates almost 70 their own medium and heavy duty trucks (all closed bodies, partially temperature-controlled ones), but uses also common carriers (for about 30% of all transports). The company runs the only one central warehouse (with climate/temperature-controlled storage sections), serving all company’s shops.
The operational characteristics of the company’s distribution network are as follow:
- more than 20 million kilometres covered during a year,
- average vehicle (delivery) route length equal to 280 kilometres,
- about 60% of the kilometres covered are loaded ones,
- about 73 thousand of routes done during a year (giving about 200 routes per day),
- average number of customers (shops) visited per one route equal to 2.7,
- the total number of tones transported during a year equal to 530 thousand (giving about 7.3 tons per one route),
- the total number of cargo units (pallets) transported during a year equal to 1.6 milion
(giving about 22 pallets per one route),
- the average weight of the cargo unit (one pallet) equal to 330 kilograms.
