In this study, we find that there are two problems when applying the techniques of discretization to obtain an approximated probability density function of the project completion time in stochastic activity networks. Namely, first, there exists neither exact data structure nor systematic scheme for the computer programming when applying the techniques of discretization; and second, error may arise from assuming independency between sub-paths in the activity network.

本研究发现在运用文献中的散式计算技术，求算随机性专案完成时间的机分配函时，存在个问题：第一，文献中既未提供明确的资结构也没有系统化的架构，足以将其转为计算机程式；第二，因为文献中的散式计算技术，皆假设随机性专案网中的各条子径彼此独，而造成明显的误差。

A new feature extraction model based on genetic programming and linear discriminant analysis in fault diagnosis is proposed.

In terms of memory hierarchy, we investigated how to improve the cache hit rate and localize data according to the characteristics of cache, master memory, local disk and remote disk in cluster systems. As for communication, features of cluster systems and different cluster internal networks are examined. Two popular parallel programming models - message passing model and share memory model - are analyzed in terms of how do they affect the cluster performance and how can we improve the cluster performance.

在处理器层面，分析了现代处理器中常用的一些技术，包括超线程技术、超长指令技术和NUMA架构等，对不同特点的程序的性能影响和如何充分利用处理器中的一些技术提升性能；在存储层次上，结合机群系统上Cache、主存、本地辅存及网络存储的存储层次的特点，分析了数据局部性、Cache命中率等对性能的影响以及提出如何提高数据局部性；通讯系统层面分析了不同机群通讯系统及不同机群通讯网络的特点；在编程模式方面，分析和比较了目前最常用两种并行编程模式--消息传递编程模式和共享存储编程模式，在机群系统上对性能的影响因子以及提出如何提高性能的方法。
