This paper examines the impact of distance-dependent spatial externalities, referred to as “edge-effect externalities”, on free-market equilibrium land use patterns. Under edge-effect externalities, maximization of production possibilities will depend on minimization of landscape fragmentation, implying that both the correct allocation and the correct arrangement of land uses will be necessary ...

This paper proposes a novel process for the allocation of human organs that are made available for transplantation. This new allocation process is intended to ensure that when an organ is assigned to a particular recipient, it i because that particular recipient is the most suitable patient to whom transplant the available organ. This process is famed in an agent-based organization – CARREL –, ...

using the treynor and mazoy model (expanded by fama to evaluate management performance for asset allocation among investment units), this paper examines the management’s performance in funds and investment companies in tehran stock exchange during 2004-2010. the results do not support the application of management market timing during the study period and managers were only able to create addit...

Cloud computing is considered to be a new service provider technology for users and businesses. However, the cloud environment is facing a number of challenges. Resource allocation in a way that is optimum for users and cloud providers is difficult because of lack of data sharing between them. On the other hand, job scheduling is a basic issue and at the same time a big challenge in reaching hi...

we consider the queueing maximal covering location-allocation problem (qm-clap) with an m/m/1 queueing system. we propose a new solution procedure based on decomposition of the problem into smaller sub-problems. we solve the resulting sub-problems both with a branch and bound algorithm and with the meta-heuristic grasp. we also solve the entire model with grasp. computational results for these ...

this paper uses a multivariate garch model to simultaneously estimate the mean and conditional variance using daily returns among different tehran sector indexes from tir 1386 to tir 1391. since different financial assets are traded based on these sector indexes, it is important for financial market participants to understand the volatility transmission mechanism over time and across sectors in...

this paper addresses the mixed integer reliability redundancy allocation problems to determine simultaneous allocation of optimal reliability and redundancy level of components based on three objective goals. system engineering principles suggest that the best design is the design that maximizes the system operational effectiveness and at the same time minimizes the total cost of ownership (tco...
