A Mathematical Model for Deriving Optimal Leasing Policies of a Satellite Operator

A Decision Making Tool for Assessment of Leasing Policies of a Satellite Operator

This paper presents the results of a study concerning the evaluation of different decisions of a Satellite Operator leasing capacity to different customers requesting different services. The study was done for Hellas-Sat (the Greek satellite operator) and addresses a real situation. Data concerning demands of several customers were collected using those available in particular organizations and...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

A mathematical model for finding the optimal locations of railway stations

Regarding the importance of competitive advantages among the transportation systems, improving the costumer’s satisfaction is an important factor in attracting them to these systems. In this research, we focus on the effects of constructing new stations on users and a new mathematical model is proposed for this problem. In the proposed model, two simultaneous effects on customers by constructin...

A Mathematical Model for Flood Protection

Many regions in the world are protected against flooding by a dike, which may be either natural or artificial. We deal with a model for finding the optimal heights of such a dike in the future. It minimizes the sum of the investments costs for upgrading the dike in the future and the expected costs due to flooding. The model is highly nonlinear, nonconvex, and infinite-dimensional. Despite this...
