英文論文寫作：離散事件的仿真模擬
最後，通過離散事件仿真(DES)，將系統的運行過程表示為一系列離散過程。每一段情節都發生在某個特定的時刻，並在適當的時候對情節結構進行轉換。在連續發生的兩次事件中，假定結構沒有發生變化;因此，仿真可以不間斷地跳轉，最終從一個事件開始到下一個事件。實際上，對大型框架的模擬受到這種順序性的限制，因為只有少量不引人註目的事件可以重新執行。
習慣的離散事件模擬使用天生的連續計算。實際上，對大型框架的模擬受到這種順序性的限制，因為只有少量不引人註目的事件可以重新實施(Lavenberg, et al.， 1983)。建議采用分布式離散事件仿真(在具有非一致性通信傳輸能力的處理器系統上執行);它可以通過在段處理器之間打包模擬來提供更好的實現。給出了基於周期編碼的分布式仿真方案。它的顯著弱點是死鎖(停止)的可能性。一些程序，以避免交通堵塞和停止位置建議。
在建立和使用模擬程序方面的常規步驟包括從一個真正的框架開始並理解其質量，
從真正創建一個模型框架的觀點適用於模擬舉行和無關緊要的角度處理的模擬模型,該模型可以應用於PC(模擬除了電腦項目並不是衡量),仿真和分析收益率真正理解和預見的行為框架。

A discrete-event simulation (DES) shows the way the operation of a system is carried out as a discrete series of proceedings in the end. Every episode happens at a specific moment in due course and scores a transform of situation in the structure. Among two successive happenings, no transformation in the structure is presumed to happen; therefore the simulation can nonstop hop ultimately beginning one incident to the subsequent. Practically speaking, simulations of vast frameworks are constrained by this sequentiality, in light of the fact that just an unobtrusive amount of incidents can be re-enacted.
Customary discrete-event simulations utilize an innately consecutive calculation. Practically speaking, simulations of vast frameworks are constrained by this sequentiality, in light of the fact that just an unobtrusive amount of incidents can be re-enacted (Lavenberg, et al., 1983). Distributed discrete-event simulation (performed on a system of processors with non-concurring correspondence-conveying abilities) is recommended as an option; it might give better implementation by parcelling the simulation among the segment processors. The fundamental distributed simulation plan, which utilizes period encoding, is portrayed. Its significant weakness is a probability of deadlock (stop). A few procedures for gridlock evasion and halt location are recommended.
Regular strides in building and utilizing a simulation program comprises of Beginning with a genuine framework and comprehension of its qualities,
Creating a model from the genuine framework in which viewpoints applicable to simulation are held and unimportant angles are disposed of Making a simulation of the model that can be applied to a PC (simulations apart from PC projects are not measured here), and Analysis of simulation yields to comprehend and foresee the conduct of the genuine framework.
