    • A computer displays nested windows representing the structure of logical and arithmetic related objects. The objects have a logical description that defines relationships between the objects including a combination of significance and precedence. The description is parsed to identify the significance and precedence of each object. Delimiters are extracted which define the significance and precedence. The relationships are displayed with nested windows on the computer display as defined by the delimiters where the relationships having a higher order of precedence are arranged in windows on top of other windows that represent lower order or precedence. The objects and relationships may be edited based on the computer display
    • 计算机显示表示逻辑和算术相关对象的结构的嵌套窗口。 对象具有定义对象之间的关系的逻辑描述,包括重要性和优先级的组合。 解释描述以识别每个对象的重要性和优先级。 提取定界符定义重要性和优先级。 这些关系以计算机显示器上的嵌套窗口显示,由分隔符定义,其中具有较高优先级顺序的关系排列在表示较低次序或优先级的其他窗口之上的窗口中。 对象和关系可以根据计算机显示进行编辑

    • The steady state condition of a subject product is projected using transient data developed through actual or simulated tests or operations. The transient data represent the monotonic or cyclic property states of the product while subjected to environmental or operational conditions. A first and second property state value corresponding to the transient data for selected times within the test period are identified. A first and second rate-of-change value corresponding to the change in the property states at the selected times are then computed. A time constant value is next computed by applying the time interval and the first and the second rate-of-change values to a time constant function. A projected steady state condition value is next computed by applying the second rate-of-change value, the second state value and the time constant value to a projected steady state conditions function. The projected steady state condition value is compared with a previously computed projected steady state condition value. The difference between these two steady state condition values is then compared with a threshold value to determine if a satisfactory projection of the steady state condition has been obtained. Full cycles of the property state of the product may be projected. Preferably, a closed form solution for the time constant and the projected steady state conditions function are used for the projection.
    • 使用通过实际或模拟测试或操作开发的瞬态数据来预测主题产品的稳态条件。 瞬态数据表示产品在环境或操作条件下的单调或循环性状态。 识别与测试周期内选定时间的瞬态数据相对应的第一和第二属性状态值。 然后计算与所选择的时间的属性状态的变化对应的第一和第二变化率值。 接下来通过将时间间隔和第一和第二变化率值应用到时间常数函数来计算时间常数值。 接下来通过将第二变化值,第二状态值和时间常数值应用于投影稳态条件函数来计算投影稳态条件值。 将预计稳态条件值与先前计算的投影稳态条件值进行比较。 然后将这两个稳态条件值之间的差值与阈值进行比较,以确定是否获得了令人满意的稳态条件投影。 产品的财产状态的完整周期可以预计。 优选地,用于时间常数的闭合形式解和投影稳态条件函数用于投影。
