Queuing theory teaching demonstration and statistics device

Abstract

The invention discloses a queuing theory teaching demonstration and statistics device, which comprises a target sphere mixing mechanism, a mounting rack, a probability demonstration mechanism, a leveling mechanism, a bottom connecting plate and a height adjusting mechanism. The target sphere mixing mechanism is arranged above the mounting rack, and the probability demonstration mechanism is arranged in the mounting rack; the leveling mechanism and the height adjusting mechanism are arranged on the lower side of the mounting rack; and during use, random probabilistic testing is performed on a target sphere through a manual uniform mixing assembly, a primary probability demonstration assembly and a multi-stage probability dispersion demonstration assembly, so that the occurrence process of a random event can be truly reflected, and dispersion and aggregation conditions of the target sphere can be reflected. The device has the characteristics of simplicity in use, clear statistics and demonstration, and convenience for students to understand, observe and learn.

Description

technical field [0001] The invention relates to the technical field of queuing theory teaching aids, in particular to a queuing theory teaching demonstration and statistics device. Background technique [0002] Queuing theory is a mathematical theory and method for studying the random gathering and dispersal of systems and the working process of random service systems, also known as random service system theory, which is a branch of operations research; [0003] In the process of teaching queuing theory, in order to allow students to intuitively understand the phenomenon of random gathering and dispersal of the system and the step-by-step and discrete conditions of the random service system, the distribution of probability and statistics are often used to reflect it, and various demonstration devices are usually used , can not only express probability events vividly, but also improve students' interest in learning; however, the current common probability demonstration device...

Problems solved by technology

[0003]In the teaching process of queuing theory, in order to allow students to intuitively understand the phenomenon of random gathering and dispersal of the system and the step-by-step and discrete conditions of the random service system, the probability distribution and To reflect the statistics, various demonstration devices are usually used, which can not only vividly express probability events, but also improve students' interest in learning; however, the current common probability demonstration devices are still limited to coin throwing, small balls, etc. This cumbersome and boring simulation method is not conducive to the continuous demonstration of probability events and a large number of statistics. At the same time, it will make students confined to this inherent mode, which greatly limits the students' thinking ability
