Book excerpt: This is an open access book. Management science and engineering is a systematic discipline that combines modern information technology and digital technology, and then uses some related discipline methods, such as systems science, mathematical science, economics and behavioral science, and engineering methods. After analyzing and researching some problems arising from social economy, engineering, education, finance, etc., and making corresponding countermeasures. The main purpose is to achieve control and planning, decision-making and adjustment in social, economic, education, engineering and other aspects, and then make improvements, and finally organize and coordinate. The relevant departments can be combined to achieve system management, so that the allocation of resources and the Management can be rationally optimized, so that individual functions can play the greatest role, minimize resource consumption, and maximize the optimal allocation of resources. This is also the ultimate research purpose. Liangliang Wang said: " Management is the productive force, which promotes the development of the country, society and enterprise. The relationship between management practice and management science is the relationship between theory and practice. The research on management science helps to improve the level of management, and then promote the development of the country, society and enterprises. On the other hand, management practice changes with the continuous progress of the times. It is necessary to study the current situation and trend of management science in the new era, which will help to clarify the future development direction of the discipline and discover the deficiencies in management scientific research and grasp it. The focus of management science research, thereby promoting research in management science." Therefore, it is necessary to create a space for management science practitioners, engineering practitioners, researchers and related enthusiasts to gather and discuss this current issue. The 2nd International Conference on Management Science and Software Engineering (ICMSSE 2022) aims to accommodate this need, as well as to: 1. provide a platform for experts and scholars, engineers and technicians in the field of management and software engineering to share scientific research achievements and cutting-edge technologies 2. understand academic development trends, broaden research ideas, strengthen academic research and discussion, and promote the industrialization cooperation of academic achievements 3. Promote the institutionalization and standardization of management science through modern research The conference will focus on software processing and information systems, combining research directions in the field of management. ICMSSE International Conference on Management Science and Software Engineering welcomes papers dealing with management systems research, software programming, management systems optimization, information systems management, etc. The 2nd International Conference on Management Science and Software Engineering (ICMSSE 2022) will be held in Chongqing on July 15-17, 2022. The conference sincerely invites experts, scholars, business people and other relevant personnel from domestic and foreign universities, research institutions to participate in the exchange.
