According to the structure characteristics of railway viaduct with light floating slabs, a frequency domain dynamic model of the vehicle-light floating slab track-viaduct bridge vertical coupling system is established. The Green functions are used to quickly calculate the receptance response of the system, and then the pseudo excitation method is used to further analyze the parameter influences...

This work is devoted to the question of the optimal allocation of electricity production resources within several production technologies. We consider the equilibrium of the real– time electricity market which is effected by the competition of different power generators. For this equilibrium, the best bid strategies of electricity producers are obtained which yields for each technology the opti...

Given the scarcity of COVID-19 vaccines, equitable (fair) allocation limited vaccines across main administrative units a country (e.g. municipalities) has been an important concern for public health authorities worldwide. In this study, we address inside countries by developing novel, evidence-based mathematical model that accounts multiple priority groups elderly, healthcare workers), vaccine ...

The paper presents a conceptual framework for a resource management system designed for remote virtual laboratory experimentation in both the natural and physical sciences domains. One of the key problems addressed in this paper is the use of a mathematical model to solve resource allocation or task scheduling problems in a dynamic Grid environment that consists of a heterogeneous distributed c...

The allocation problem in health care can be characterised as a mathematical programming problem but attempts to incorporate uncertainty in costs and effect have suffered from important limitations. A two-stage stochastic mathematical programming formulation is developed and applied to a numerical example to explore and demonstrate the implications of this more general and comprehensive approac...

The Cooperative Water Allocation Model (CWAM) is designed within a general mathematical programming framework for modeling equitable and efficient water allocation among competing users at the basin level and applied to a large-scale water allocation problem in the South Saskatchewan River Basin located in southern Alberta, Canada. This comprehensive model consists of two main steps: initial wa...

optimization of land allocation in golestan province for planting agricultural crops using compromise mathematical programming introduction: rational planning and optimization of agriculture are essential because of water and land constraints, the need to increase economic profit and to reduce the negative impacts of fertilizers and pesticides. to this end, decision-makers and planners need to ...
