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.

所提供的数据集包含物流配送网络设计数学模型的典型参数。数据按照模型参数列表（文件：物流配送网络设计问题 - 描述 - Redmer_A.pdf）进行组织，该列表附于数据集（文件：物流配送网络设计问题 - 数据集 - Redmer_A.txt）中。这些数据源自一家波兰的综合性商品（快速消费品，FMCG）零售公司，该公司运营着近200家中型店铺，覆盖波兰国土的70%。平均店铺的营业面积为500平方米，销售约7000种不同的产品（SKU）。该公司雇佣了超过5000名员工，运营着近70辆中型和重型封闭式货车（其中部分为部分温控车型），同时也使用普通承运人（约占所有运输的30%）。公司拥有唯一的中央仓库（包含气候/温控存储区域），为所有店铺提供服务。公司的配送网络运营特征如下：- 年内覆盖超过2000万公里；- 平均车辆（配送）路线长度为280公里；- 覆盖的公里数中约有60%为载货状态；- 年内完成约73000条路线（相当于每天约200条路线）；- 每条路线平均访问的客户（店铺）数量为2.7；- 年内运输的总吨数达到53万吨（相当于每条路线约7.3吨）；- 年内运输的货物单元（托盘）总数达到160万（相当于每条路线约22个托盘）；- 货物单元（一个托盘）的平均重量为330公斤。
