Weighted sum model. In decision theory, the weighted sum model ( WSM ), [1] [2] also called weighted linear combination ( WLC) [3] or simple additive weighting ( SAW ), [4] is the best known and simplest multi-criteria decision analysis (MCDA) / multi-criteria decision making method for evaluating a number of alternatives in terms of a number ...
Weighted product model. The weighted product model ( WPM) is a popular multi-criteria decision analysis (MCDA) / multi-criteria decision making (MCDM) method. It is similar to the weighted sum model (WSM). The main difference is that instead of addition in the main mathematical operation, there is multiplication.
The program evaluation and review technique ( PERT) is a statistical tool used in project management, which was designed to analyze and represent the tasks involved in completing a given project .

In statistical quality control, the CUSUM (or cumulative sum control chart) is a sequential analysis technique developed by E. S. Page of the University of Cambridge.
Data analysis is the process of inspecting, cleansing, transforming, and modeling data with the goal of discovering useful information, informing conclusions, and supporting decision-making. [1] Data analysis has multiple facets and approaches, encompassing diverse techniques under a variety of names, and is used in different business, science ...
The sum of the terms oscillatesbetween two values (for example, 2, 0, 2, 0, 2,... This is a different type of divergence. See for example Grandi's series: 1 − 1 + 1 − 1 + ···. If |r| > 1, the terms of the series become larger and larger in magnitude. The sum of the terms also gets larger and larger, and the series does not converge to a sum.
Geometric progression Diagram illustrating three basic geometric sequences of the pattern 1 ( rn−1) up to 6 iterations deep. The first block is a unit block and the dashed line represents the infinite sum of the sequence, a number that it will forever approach but never touch: 2, 3/2, and 4/3 respectively.
