Query: Mathematical simulation of package delivery optimization using a
  combination of carriers   A variety of goods and services in the contemporary world requires permanent
improvement of services e-commerce platform performance. Modern society is so
deeply integrated with mail deliveries, purchasing of goods and services
online, that makes competition between service and good providers a key
selection factor. As long as logistic, timely, and cost-effective delivery
plays important part authors decided to analyze possible ways of improvements
in the current field, especially for regions distantly located from popular
distribution centers. Considering both: fast and lazy delivery the factor of
costs is playing an important role for each end-user. Given work proposes a
simulation that analyses the current cost of delivery for e-commerce orders in
the context of delivery by the Supplier Fleet, World-Wide delivery service
fleet, and possible vendor drop-ship and checks of the alternative ways can be
used to minimize the costs. The main object of investigation is focused around
mid and small businesses living far from big distribution centers (except edge
cases like lighthouses, edge rocks with very limited accessibility) but
actively using e-commerce solutions for daily activities fulfillment. Authors
analyzed and proposed a solution for the problem of cost optimization for
packages delivery for long-distance deliveries using a combination of paths
delivered by supplier fleets, worldwide and local carriers. Data models and
Add-ons of contemporary Enterprise Resource Planning systems were used, and
additional development is proposed in the perspective of the flow selection
change. The experiment is based on data sources of the United States companies
using a wide range of carriers for delivery services and uses the data sources
of the real companies; however, it applies repetitive simulations to analyze
variances in obtained solutions.
