    • Control of a multi-variable process throughout a plurality of successive, distinct operational phases of the process involves accumulation of sets of values of the process and quality variables (a-j) from previous multiple operations of the process through all its phases, as respective datasets of a historical record. Each dataset includes an identifier (p) of the phase to which it relates. The current values of the applicable process variables (Qa-Qh) during each phase and the phase identifier (p) are indicated on respective axes (Xp, Xa-Xh) of a multi-dimensional display in relation to an operational envelope which defines bounds (UL, LL) for the values of the individual process and quality variables {a-j) relevant to that phase and which is derived from the datasets of the historical record identified with that phase. Changes in the current process variables (Qa-Qh) result in changes of the bounds (UL, LL), and alarm is given when a current value departs from within them. Correction of an alarm condition is made manually or automatically in accordance with calculation of required change of value of one or more manipulatable process variables (a-c).
    • 在过程的多个连续的,不同的操作阶段中对多变量过程的控制涉及从过程的所有阶段的先前多次操作中累积过程值和质量变量(aj)的集合,作为相应的数据集 一个历史记录。 每个数据集包括与其相关的阶段的标识符(p)。 相对于定义边界的操作包络,在多维显示器的各个轴(Xp,Xa-Xh)上指示每个阶段期间适用的过程变量(Qa-Qh)和相位标识符(p)的当前值 (UL,LL)用于与该阶段相关的单个过程和质量变量{aj)的值,并且是从与该阶段确定的历史记录的数据集中得出的。 当前过程变量(Qa-Qh)的变化导致边界(UL,LL)的变化,并且当当前值从其中偏离时给出报警。 根据计算一个或多个可操作过程变量(a-c)的所需值的变化,手动或自动地进行报警条件的更正。
