The methodology classified the objects of module partition to improve the flexibility and maneuverability. In addition, the methodology focused on research of module partition method, which faced the category of "modular transformation of the existing products ". The methods commendably meet the current needs of enterprises and have strong practical significance. In the end, presented the corresponding mathematical methods.

针对两类方法的优缺点，提出了一种柔性化模块划分方法，该方法突出了模块划分的对象分类，在提高划分方法柔性的同时，也更具可操作性；并着重研究分析了"面向已有产品模块化改造"范畴的模块划分分组方法，并明确了相应的谱系聚类数学方法，该方法较强地适应了当前企业的设计需求，具有较强的实践意义。

This thesis is divided into six parts. The first chapter is preface, the current status of research in the inverse problems for parabolic partial differential equations is reported; the second chapter is "regularization methods for numerical differentiation and their applications ", in this chapter we investigate many regularization methods from a viewpoint of regularization theory and algorithm, some applications in the inverse problems for parabolic partial differential equations are given; the third chapter is "spectral regularization methods". Based on Fourier analysis, within the framework of regularization theory, we apply the spectral methods to some ill-posed problems. Many numerical experiments are done in order to show the validity of the methods; the fourth chapter is devoted to wavelet dual least squares method and a revised wavelet method; in the fifth chapter,we combine finite difference method with method of lines and apply it to the backward heat conduction problem in time; in the sixth chapter "identification problems for unknown source ", the essence and the degree of two problems related to source identification are pointed out, at the same time, some numerical methods are reported.

The algorithm is proved to be convergent theoretically and implemented for numerical calculation.Thirdly, two kind problems of multi-unit system maintenance based on the discrete-state deterioration model are analyzed:To achieve the optimization aim of series system consist of two types of units with different failure mode, an opportunistic policy is presented to combine the corrective and condition-based maintenance. The optimal model based on this policy is built and an iteration algorithm based on sequential decision is proposed according to the characteristic of discrete-state deterioration model.

第三、在部件优化分析的基础上，针对基于离散状态劣化模型的多部件系统视情维修决策中的两类典型问题，提出了相应的机会维修策略和优化分析方法：(1)针对串联系统由分别采用视情维修和事后维修的两类部件组成的情况，提出了一类事后维修与视情维修相结合的机会策略，建立了相应的多部件系统维修优化模型，并根据离散状态劣化模型的特点，提出了一类基于序贯决策的求解方法。
