“…Process and quality improvement tools especially utilizing lean and Six Sigma concepts are widely used in both manufacturing and service sectors (Freimut et al, 2005;Soković et al, 2009;Verma et al, 2021;Alblooshi et al, 2022;Bader et al, 2020;Badiru, 2005;Bhandari et al, 2021;Soltani and Bhandari 2023;Bartlett et al, 2023;Verma et al, 2022). Design of Experiments (DOE) is a powerful technique that is often used as an applied statistical tool that deals with planning, conducting, analyzing, and interpreting controlled experiments in a laboratory to explore and evaluate the factors that control the value of a factor or various factors (Bower, 2023). This technique can be used in various situations including but not limited to improving processes and systems, understanding the relationship between the response variable and different factors, and identifying factors that significantly impact the outcome of the response variable (Srebrenkoska et al, 2016;Walston et al, 2022).…”

This study is aimed at using various statistical analyses within the Design of Experiments (DOE) technique to investigate and analyze the effect of welding process parameters on the tensile strength of A36-grade mild steel. Three process parameters and two corresponding levels were considered and the MIG welding process was performed. The ideal conditions to achieve the highest strength were determined and the results were obtained by running the design on a statistical software Minitab. This experimental study found that the only factor having a significant contribution to the tensile stress of the plates in the selected scenario is the weld speed. In addition, this study provides valuable insights for enhancing welding procedures and techniques. The paper concludes with a reasonable interpretation of the test results and justifies the research questions that were proposed.

“…The design of experiments (DOE) method is employed to efficiently plan and conduct experiments, yielding precise data that can be analyzed to generate reliable and unbiased results [13]. DOE, as a systematic approach, proves valuable in addressing challenges encountered in research, development, and manufacturing [14]. It serves multiple purposes, including comparison, variable screening, identification of transfer functions, system optimization, and robust design.…”

This study aimed to prepare tablets of black pepper extract using the Design of Experiments (DOE) approach. The levels of three factors—compressional force, croscarmellose sodium (CCS), and microcrystalline cellulose (MCC)—were screened using the one-factor-at-a-time technique, followed by the DOE utilizing the Box–Behnken design. The respective variations for each factor were as follows: compressional force (1500–2500 psi), CCS (1–3%), and MCC (32–42%). The results indicated that compressional force significantly decreased tablet thickness and friability, while increasing hardness and prolonging disintegration time. CCS significantly shortened disintegration time but did not affect tablet thickness, hardness, and friability. MCC, on the other hand, significantly increased tablet thickness and hardness, while significantly decreasing friability. Furthermore, the study observed interactions among factors and quadratic effects of each factor, which significantly influenced tablet properties. The optimal tablet formulation consisted of 2.2% CCS, 37% MCC, and a compressional force of 2000 psi. These tablets had a weight of 198.39 ± 0.49 mg, a diameter of 9.67 ± 0.01 mm, a thickness of 1.98 ± 0.02 mm, a hardness of 7.36 ± 0.24 kP, a friability of 0.11 ± 0.02%, and a disintegration time of 5.59 ± 0.39 min. The actual values obtained using the optimal conditions closely matched the predicted values, with a low percent error (less than 5%). In conclusion, the application of the DOE approach successfully developed tablets of black pepper extract, which can be utilized as food supplement products.
