Optimizations of discrete garbage collections in computer reliability systems

In computer science community, garbage collection is a dynamic storage management technology to ensure the reliability of computer systems. In this paper, we consider two discrete garbage collection policies to meet the goal of time consumption for a generational garbage collector. That is, garbage collections occur at a nonhomogeneous Poisson process, (a) tenuring collection is triggered at the Nth minor collection preventively or at a threshold amount [Formula: see text] of surviving objects correctively, whichever takes place first, and (b), tenuring collection is triggered at the first collection when the amount of surviving objects has exceeded a threshold level [Formula: see text] and major collection is triggered at discrete times kT for a given T. Using the damage process and renewal theory, the expected cost rates are obtained, and their optimal policies for tenuring and major collections are discussed analytically and computed numerically.

Current Status and Prospects of Reliability Test Research on Special Computers

Special computers are widely used in aerospace, ships, weapons and other fields. More and more attention is paid to the reliability of special computers. Although my country started late in this regard, it has achieved some results after continuous exploration by a large number of scientific research institutions, and has gradually kept up with the pace of research in developed countries. This article first summarizes the research status and importance of accelerated life test in reliability test research, and analyzes the key technology and development of reliability test of special computer. Reliability analysis can solve the failure problems that cannot be explained by traditional quality analysis methods, and will surely make remarkable achievements in the future industrial development. The summary of this article will provide theoretical reference for subsequent related research.

Analysis of Computer Reliability and Simulation of Optimization Algorithm Based on Baumol Model

With the rapid development of economy, computer technology with the advantages of real-time performance, and high efficiency has been rapidly applied in the field of financial management. The construction of financial management system, which is of digitization and informationization, becomes more and more comprehensive. How to determine the "optimal cash holdings" is the key and difficult decision for financial management in modern enterprises. This paper firstly discusses the development status of modern computer financial management technology, and then makes comparative analysis of the existing four kinds of optimal cash holdings models. On this basis, it has constructed the optimal cash holdings model with Baumol by the aid of computer technology, and the model has been carried out computer simulation and analysis in this paper. The results show that the constructed optimal cash holdings model can help enterprise finance make reasonable decision, which is very helpful to improve the efficiency of financial management.
