Introduction to the content of system modeling

Briefly introduces the functions, characteristics and application fields of mainstream system modeling and simulation software, and takes ProModel software as an example to introduce the software's Element composition and usage steps.

"Logistics System Modeling and Simulation" tells that before the popularization of computers, logistics system simulation generally used mathematical methods to establish mathematical models.

This composite structure-level description is the basis for complex system and large system modeling.

System modeling is mainly used in three aspects. 1 Analyze and design the actual system. For example, when analyzing and designing a new system, the engineering community usually conducts mathematical simulation and physical simulation experiments first, and then conducts physical experiments on site.Mathematical simulation is simpler and easier to do than physical simulation.

The system model is generally not the system object itself, but the description, imitation and abstraction of the real system. For example: Globe 1 is an approximate or concentrated reflection of the essence and characteristics of the earth's prototype. The system model is composed of the main factors that reflect the essence or characteristics of the system. The system model reflects the relationship between these main factors.

System model refers to a way to abstract and describe a complex system. Expand knowledge: It is a visual representation of the internal components of the system and their interrelationships, usually presented in the form of charts, graphics or codes.

System Model Modeling method

According to the different system objects, the methods of system modeling can be divided into reasoning, experimental, statistical analysis, hybrid and similar methods. According to the different descriptions of system characteristics, the methods of system modeling can include state space method, structural model analysis method (ISM) and least squares estimation method (LKL).

Implement optimal control over the system. The key or premise of using control theory to design a controller or optimal control law is to have a mathematical model that can characterize the characteristics of the system.

The modeling methods of the logistics system are mainly as follows: Optimization method The optimization method is to use linear planning, integer planning, nonlinear planning and other mathematical planning techniques to describe the quantitative relationship of the logistics system in order to obtain optimal decision-making.

Rumbaugh et al. proposed the object-oriented modeling technique (OMT) method, adopted the object-oriented concept, and introduced various language-independent representations.

What is UML system modeling

1. UML: Unified modeling language Function: an open method for explaining, visualizing, building and writing a product of an object-oriented, software-intensive system under development . UML is not an industrial standard.Accurate, but under the auspices and funding of Object Management Group, UML is gradually becoming an industrial standard.

2. UML: Unified Modeling Language, also known as standard modeling language. It is a language used for visual modeling of software-intensive systems. The definition of UML includes two elements: UML semantics and UML notation.

3. UML means unified modeling language. UML is an abbreviation of unified modeling language. It is a standardized modeling language composed of a set of integrated diagrams to help system and software developers specify, visualize, build and record workpieces of software systems, as well as for business modeling and other non-software systems.

4. UML (abbreviation for Unified Modeling Language) is a unified modeling language used for visual modeling of software-intensive systems. UML is a standard language for explaining, visualizing and compiling documents for the products of object-oriented development systems. II: Use case diagram, class diagram, sequence diagram, status diagram, activity diagram.

What is system modeling?

Unified Modeling Language (UML is the abbreviation of Unified Modeling Language) is a language used for visual modeling of software-intensive systems. UML is a standard language for explaining, visualizing and compiling documents for the products of object-oriented development systems.

Modeling is to build a model, which is an abstraction of things in order to understand things, and an unambiguous written description of things. The process of establishing a system model is also known as modeling. Modeling is an important means and premise for researching systems. Any process that uses a model to describe the causal relationship or interrelationship of the system is a modeling.
