Embodiment 1

[0018] like figure 1 As shown, the teaching aid of the logistics from-to table algorithm in this embodiment includes several magnetic unit blocks 1 arranged on the magnetic pallet 2. The magnetic pallet 2 has certain magnetism and can absorb the magnetic unit blocks 1 tiled on it. , the magnetic unit block 1 is a square magnetic unit block of the same size, the back side is magnetic, and the front side can be written on with a pen. The magnetic unit block 1 tiled on it forms a matrix of magnetic unit block 1 from to (n+3)×(n+3), where the second magnetic unit block in the first row to the (n+1)th The first magnetic unit block and the second magnetic unit block to the (n+1)th magnetic unit block in the first column correspond to different devices from to the table, and the n+2th row (column) is the weight of a group of parts (the weight is equal to the weight product of each part), and the n+3th row (column) is the sum of the penalty points from the to table. During the calcu...

Embodiment 2

[0020] like Figures 2 to 3 Shown, the teaching aid of the logistics from to table algorithm of the present embodiment and figure 1 The structure of the teaching aid for the logistics from-to table algorithm shown is basically the same. The difference is that the magnetic unit block 1 is a hollow magnetic unit block, and the socket 3 is formed on the side of the magnetic unit block 1 . Preferably, the magnetic unit block 1 can be set as an inner cross hollow magnetic unit block, and four sockets 3 are formed on the four sides of the magnetic unit block 1, and the same direction sockets 3 of each magnetic unit block 1 are connected, and in the socket 3 It is provided with a cutting strip 4 that is longer than the edge of the magnetic pallet and has a smaller width than the width of the socket, which can be extracted at will. When in use, if a whole row or column of mobile magnetic unit blocks is required, the inserting strips only need to be inserted into the sockets of the m...

Embodiment 3

[0023] like Figure 4 As shown, the teaching aid of the logistics from-to table algorithm in this embodiment is basically the same in structure as the teaching aids of the first two kinds of logistics from-to table algorithms. The difference is that the teaching aid for the logistics from-to table algorithm also includes pallet handles arranged on the front side of the magnetic pallet 2 and the edges on the left and right sides. The edge of the supporting plate is composed of several blocking pieces 6, which are concave and convex. Each blocking piece 6 is arranged in the middle of two adjacent magnetic unit blocks 1, and the socket 3 of the magnetic unit block 1 is exposed outside the blocking piece 6. In addition, two corner stoppers 6 are provided at the front two corners of the magnetic pallet 1 . The magnetic unit block can be fixed on the magnetic supporting plate by setting the edge of the supporting plate to prevent the magnetic unit block from slipping.

Abstract

The invention discloses a teaching tool of from-to charts in logistics. The teaching tool comprises a magnetic supporting plate (2) and a plurality of magnetic unit blocks (1) attached on the magnetic supporting plate (2). The magnetic unit blocks are arranged in a matrix allowing writing. According to this arrangement, the problem of multiple repeated drawings of from-to charts in chalks on blackboards by teachers can be avoided. The teaching tool has the advantages of being clear in structure, harmless for environment and teachers health, high in efficiency, and uninfluenced by conditions, such as blackboards in classrooms. Therefore, the cost of chalks and teaching hours can be saved and the comprehensive benefit of the teaching tool is better as the quantity of and the times of computation is larger.

Description

technical field [0001] The invention relates to a teaching aid, especially a teaching aid for logistics from-to table algorithm. technical background [0002] From to table is a knowledge point in the course "Logistics Analysis and Facility Planning" of industrial engineering majors in colleges and universities. In traditional teaching, teachers often need to use the blackboard to draw tables to complete the calculation. During the calculation process, one is due to some parts or materials. There are a lot of production equipment involved. Second, due to the need to optimize and adjust the existing production process, the teacher needs to draw multiple from-to tables on the blackboard during the calculation process. In addition, the capacity of the blackboard is limited. It needs to be wiped and updated continuously. These tasks take up a lot of teaching time. Moreover, after one calculation, the teacher inhales a lot of dust and stains the clothes. The next time the calcula...
