Description

TECHNICAL FIELD This application relates to the field of industrial technologies, and in particular, to an engineering template creation method, an engineering project construction method, an engineering template creation apparatus, an engineering project construction apparatus, and a computer-readable storage medium. BACKGROUND Most existing modular engineering is implemented based on predefined templates that can be modified by engineering users. However, such predefined templates are typically manually compiled by experts in the field. This not only requires extensive professional expertise but also takes a long time. Even for the experts, constructing templates poses a considerable challenge when system complexity is relatively high. In addition, most templates are fixed and cannot be automatically modified based on user requirements, and can only be manually modified by an engineer based on a requirement of the engineer. Moreover, many engineering suppliers, such as an engineering, procurement, and construction (EPC) contractor and a system integrator, have a large quantity of past projects. If these projects cannot be reused, they will no longer generate profits for these companies, since not all companies are capable of creating a usable template library from their past projects on their own. Therefore, a person skilled in the art is still devoted to finding another implementation solution of modular engineering. SUMMARY In view of this, in embodiments of this application, in an aspect, an engineering template creation method and an engineering project construction method are provided, and in another aspect, an engineering template creation apparatus, an engineering project construction apparatus, and a computer-readable storage medium are provided, thereby implementing modular engineering.
