“…In the FFD experiments, the wide range of the set factor levels resulted in the target peaks not reaching the baseline separation under most conditions, and some of the experimental results were zero, which was not conducive to the analysis of factor effects with missing information. CCD was the most commonly used RSM experiment, which can obtain a large amount of information about experimental variables and experimental errors with a minimum number of test cycles [30]. The experimental factors and the levels of the CCD experiment are shown in Table 2.…”

In this study, the capillary electrophoresis‐photodiode array detector was employed for the analysis of four iridoid compounds in Gentiana macrophylla Radix (RGM), and the method was optimized based on the concept of analytical quality by design (AQbD). The peak areas relative standard deviation (n = 3) and resolution of the four analytes were selected as critical method attributes. Fractional factorial design test combined with Pareto analysis were employed to screen critical method parameters (buffer concentration, pH, sodium dodecyl sulfate [SDS] micelle concentration, temperature, and voltage). Subsequently, three main factors (buffer concentration, buffer pH, and SDS concentration) were selected by central composite design test for constructing the design space. The optimal separation conditions as follows: capillary column (50.2 cm × 50 µm, detection length 40 cm). Working background electrolyte consisted of 51 mmol/L borax solution (pH = 9.47) and 40 mmol/L SDS. The samples were injected by pressure (5 s at 0.5 psi) and the detection was performed at 254 nm. Applied voltage was 20 kV and column temperature was 23°C. The developed method is rapid and reliable for the quantitative analysis of four iridoid compounds in RGM, providing a reference for the application of AQbD concept in the analysis of natural products.

“…[25,26] The value of Z1 in simplex optimization provides a solution for optimizing the farmers' profit by an average price. [27,28,29] The value of Z2 in simplex optimization provides a production solution based on the average amount of consumption. In this case, Pareto makes a representative solution philosophy in deciding production and optimization criteria Z1 and Z2 for medium-quality and super-quality rice in the form of graphs.…”

Indonesian agricultural production is unpredictable. The harvest quality causes this is not-optimal harvest quality. The researchers provide a solution by utilizing a severe game design model as a learning medium to make decisions for optimizing production. In comparison, Blockchain technology is for data security, Distributed ledgers and Smart Contracts. The transaction between producers and consumers are permanent and verified. For the literature study of optimization to maximize farmers' production, the researchers use Simplex Method as an objective function and the Pareto function as an optimization model for multiple problems by finding solutions for all purposes to improve farmers' production. Multi-Objective Optimization, Linear Programming, Blockchain, and Hierarchical State Finite Machine are needed to design a serious game. This study designed Hierarchical State Finite Machine Serious Game using Blockchain and Multi-Objective Optimization method as a learning medium to simulate farmers making decisions In producing agricultural quantities based on consumer demand, stock, price, season, and planting time. Blockchain is used to track the availability of farm stocks so that the supply of consumer needs is met.

“…Heena Sharma and Dr. N.M Suri (2017) categorized the defects in LV Electrical Panels during in-process and at final stage using Pareto analysis and found that 27% rejections are due to poor welding. Polak et al (2015) evaluated the cut quality of Hydro abrasive metal cutting by Pareto method and Abhay et al (2014) studied the reasons for rejection of forging of cam shaft gear in a leading forging industry and found that furnace issues and die crack are the predominant ones. Joshi and Jugulkar (2014) analysed the reasons for rejection of castings from an industry using Pareto analysis and found that flash, mould shifting and buckling are the major factors contributing for rejections.…”

The background of this paper is to find out the predominant types of defects that occurs during the fabrication of pump fed rocket engines. Pump fed rocket engine which works on gas generator cycle is used in operational launch vehicles. The number of non-conformances are to be reduced to improve the reliability of the engine. The non-conformances reported during fabrication of twenty numbers of the engine realised over a period of four years are classified under different heads. Pareto analysis was carried out and found that the nonconformances due to weld shrinkage (process limitation), operator mistakes (human error) and free condition ovality (raw material) are the pre-dominant ones. The suggestions for process improvement leading to reduction in non-conformances per engine are also highlighted in this paper.
