Abstract:	在系統設計中，負載規劃作業乃是相當核心且關鍵的程序，若疏忽其重要性，可能導致系統嚴重的損傷或效率下降。本研究即著重於系統負載規劃之探討，試著瞭解分負載系統操作狀況。運用蒙地卡羅模擬法，以隨機變數判斷元件失效，並依據設計的負載調整策略，規劃元件負載分配。本論文運用此模擬法做了幾項探討：(一)結合開路、閉路概念，對系統進行關鍵分析，決定各元件之關鍵性優先次序；(二)以關鍵分析結果，觀察對高關鍵性元件改善之情形；(三)探討元件負載隨時間變動之機率分佈，試著在當中瞭解實際系統及元件的行為、表現。在關鍵分析結果發現，確保系統最高關鍵元件完善後，次關鍵元件將不再是預期中所需關心的元件。 The management of load-sharing in a system operation is critical work due to that an improper arrangement of loads will cause the reduction of system life and efficiency. The purpose of this thesis is to study the effects of loading adjustment on the system performance. To realize the operating situation of an assumed system, Monte Carlo method is included to simulate the system operation based reliability theory. Some applications are achieved by the simulation: (1) determine the priority sequence of components in system by combining the simulation with concept of short or open, (2) observe the system performance after improving the character of components with highly priority, (3) estimate the distribution of load probability varying with time and find out the characteristic of components in the system performance. In the study of priority analysis, after guaranteeing the most important component behavior, the next priority component will be changed, not as shown in the list of initial priority analysis.
