With the emergence of new technologies and services, it is very important to accurately identify the factors that affect the design of the wireless access network and define how to take them into account to achieve optimally performing and cost-efficient networks. Till now, most existing efforts have been focused the basic access capability. This article describes a way to deal with the trade-offs...
There are several factors that influence the design of optimal IEEE 802.16e networks. In the first stage of the network development, the most important issue is to find an appropriate solution for the base station location from a given set of candidate sites. The network can be considerably improved if the base station location solution found during the planning phase is designed to achieve optimal...
Based on the management goals of order planning of the iron-steel plants, a mixed integer programming model for the order planning is constructed. The goals include balancing production capacity and minimizing the total cost of infringing contracts. As the data of orders and processes are put together to make a point graph, the problem of order planning is transferred into an improved traveling salesman...
