In programming, a program or subroutine required to complete a certain function; Or refers to an independent program unit that can be processed by compilers, assemblers, etc;
Or refers to a part of a large software system.
A module, also known as a component, is a collection of program statements that can be individually named and independently perform certain functions (i.e., a collection of program code and data structures). It has two basic features: external features and internal features.
External features refer to the interface between a module and the external environment (i.e. the way other modules or programs call the module, including input and output parameters, referenced global variables) and the functionality of the module; Internal characteristics refer to the characteristics of the internal environment of a module (i.e. the local data and program code of the module).
There are various types of modules, such as unit operation module (heat exchanger, distillation tower, compressor, etc.), calculation method module (accelerated convergence algorithm, optimization algorithm, etc.), physical and chemical properties module (vapor-liquid phase equilibrium calculation, enthalpy calculation, etc.), etc.
