The purpose of this paper is to determine the influence of the factors of industrial and manufacturing engineering on quality of services that are provided in digital legal proceedings of the Asia-Pacific region, based one Big Data, blockchain, and AI. The authors model the influence of the factors of industrial and manufacturing engineering on quality of legal proceedings in countries of the Asia-Pacific region with the help of correlation analysis. Simplex method is used for determining the optimal influence of the factors of industrial and manufacturing engineering on quality of legal proceedings in countries of the Asia-Pacific region. It is determined that the potential of increase of quality of services of digital legal proceedings based on managing the factors of industrial and manufacturing engineering is more vivid in developing countries (33.55%) than in developed countries (9.36%). The authors reflect a new view on the prospects of development of legal proceedings - from the position of consumers’ interests’ protection, emphasizing on quality of the provided public services. Due to this, a new, alternative approach to state management of development of the legal proceedings system is developed; instead of increase of regulation, it envisages de-regulation and marketization of legal proceedings. An original approach to managing the quality of services of digital legal proceedings is offered, which is based on managing the factors of industrial and manufacturing engineering. © 2021, International Journal for Quality Research.
