Then, it studies the supply chain management system as a complex system to confirm the state existing during operating of the system. After that, it conducts a probability analysis on the state which the system located by applying supplement variable method, and establishes the model of distributed parameter system in a form of partial differential equations. Combining C0 ? semigroup theory in the functional analysis, it conducts a dynamic analysis on the established mathematical model. Using this method, it obtains the mathematical expression of the dynamic solution and the steady state solution, and proves the uniqueness, non-negativity and the asymptotic stability of the system solution. This dissertation applies the Matlab tool and uses two-step, three-step Simpson integral equation to imitate the condition of system solution. Then, it adds possible mode of failure and the optimization adjustment state to the system, based on which it has established the distributed parameter system model which is described by partial differential system of equations. Combining the functional analysis C0 ? semigroup theory, it studies the established mathematical model, and obtains the mathematical expression of the dynamic solution system and the steady state solution. It has proven the existing of uniqueness of the system solution, the asymptotic stability of system solution and the system solution. In addition, it has lying the theory rationale for further analysis and the research on the optimization of system.

In some cancers, the last treater may be the surgeon or the radiation oncologist, but in most cases where there is treatment with a curative intent, the last treater is the medical oncologist, and usually this is the physician who should take on the responsibility."However, this is a problem, as many oncologists tell us that they do not have the time to take on this additional task," Dr. Ganz commented,"but we need to educate them, and to use a carrot — maybe offer a new payment for this task." This may be possible, she added, as healthcare plans are realizing the benefit of having such summary plans."I have been billing in my practice for years for this — this is not insurance fraud, this is cognitive delivery rather than doing procedure," she added.

就某些癌症而言，最后一位治疗者或许是外科医师或放射科医师，但大部分的病例在治疗时是以痊愈为目标，最后一位治疗者即为肿瘤科医师，通常这位医师应负起责任；然而，Ganz医师指出，这是个问题，因为许多肿瘤科医师告诉我们，他们没时间负起这额外的责任，我们得教育他们，以利诱的方式，或许是为了要他们做这件事而加薪；她补充道，这是有可能的，因为健康照护计画单位正理解到有著如此的概要计画能带来益处，她表示，多年来她已在这方面申报请款，这并不是讹诈保费，而是取之有道。
