working set model
替換頁面時只能替換自己原本已擁有的頁面。 (2) Spatial Locality: 在某一區中某一位置被參考(Reference)，則鄰近的位置. 也極可能被Reference；如Array Operation。 • Working – Set Model (工作集模式): 一個以Locality 為觀念來預測 process 的所需頁框數。 (1) 用參數Δ 來定義Working-Set Window。它的想法是檢查最近Δ個頁面. ,The working set model states that a process can be in RAM if and only if all of the pages that it is currently using (often approximated by the most recently used pages) can be in RAM. The model is an all or nothing model, meaning if the pages it needs to, 利用Working Set Model “預估” 各Process 在不同執行時期所需的頁框數，並依此提供足夠的頁框數，以防止Thrashing。 作法. OS 設定一個Working Set Window (工作集視窗；Δ) 大小，以Δ 次記憶體存取中，所存取到的不同Page之集合，此一集合稱為Working Set 。而Working Set中的Process個數，稱為Working Set ..., Therefore, many paging systems try to keep track of each process' working set and make sure that it is in memory before letting the process run.
