Modern databases are crucial components of quality management systems according to the requirements of ISO 9001:2015, but their design and maintenance need significant resources. Despite the fact that modern databases are a key factor of management decision making, not all organizations can spend sufficient resources on their development what results in the necessity to find a model for database maintenance...
A network-flow method is proposed for decision making in intelligent resource flow networks systems considering the risk on the particular parts of the network. We initially assume that the probability of an adverse event happening on all sections of the network is of the same value.
Grid computing involves sharing data storage and coordinating network resources. The complexity of scheduling increases with heterogeneous nature of grid and is highly difficult to schedule effectively. The goal of grid job scheduling is to achieve high system performance and match the job to the appropriate available resource. Due to dynamic nature of grid, the traditional job scheduling algorithms...
In this paper, an algorithm of tasks scheduling on different resources is proposed. We study especially the problem of complex system distributed across multiple sites. Each site is composed of a set of equipments to be maintained according to a predefined preventive maintenance policy.
In this article, we study the dynamic scheduling problem of maintenance tasks in a distributed environment. This environment is presented as a center of competence related to several sites. The human resources have not the same qualification, and then, the assignment decision has to take care of several parameters principally with particular competences. Our contribution concerns the optimal insertion...
In a tactical battlefield, ground- and air- based robotic assets can be useful, but there is currently no one role to coordinate the use of multiple robots in the U.S. Army. The current work outlines and models the duties of a robotics operator manager (ROM), which could serve this role, using a theory of dynamic decision-making, instance-based learning (IBL). A model of the ROM is created that is...
Based on the latest literature on Environmental capacity and related theories (Bio-Capacity, Ecological footprint ), this paper examines the effect on Resettlement Environmental Capacity by taking into account factors from human society, economics, ecological environment, resources, policy and technology. On the basis of 'nature-social-economic compound system theory', the author built a conceptual...
In this paper, a general mathematical model to study the effects of two interacting populations on the depletion of resources is proposed and analysed. In modelling the system, it is assumed that the resource is a common food for both the populations while one of the population is a supplementary food for the other. A model to conserve the resource is also presented.
