Many real-world optimization problems have multiple interacting components. Each of these can be an NP-hard problem, and they in conflict with each other, i.e., the optimal solution for one component does not necessarily represent other This a challenge single-objective formulations, where respective influence that has on overall quality vary from instance to instance. In this paper, we study b...

majority of models in location literature are based on assumptions such as point demand, absence of competitors, as well as monopoly in location, products, and services. however in real-world applications, these assumptions are not well-matched with reality. in this study, a new mixed integer nonlinear programming model based on weighted goal programming approach is proposed to maximize the cap...

In recent years, Operational Business Intelligence has emerged as an important trend in the Business Intelligence (BI) market. While sharing some obvious features with “traditional” data warehouse based BI, some of the requirements for the operational flavor are strikingly different justifying the question how, or even whether, Operational BI fits into a DW environment. We describe an architect...
