Embodiment Construction

[0051] The preferred method of train dismantling order of the present invention comprises the following steps:

[0052] 1. Use the principles and methods of fuzzy mathematics to mathematically describe the process of determining the optimal disintegration of trains in industrial marshalling yards, and propose a quantitative method. The specific process is:

[0053] Step 1. Set up vehicles to be solved

[0054] There are 5 trains that need to be dismantled in a certain period of time in a railway marshalling station of an enterprise:

[0055] X={train 1, train 2,..., train 5}

[0056] Step 2. Disintegration sequence optimization factor set

[0057] U={u 1 ,u 2 ,...,u 4}={First-come-first-serve, dismantling time, departure and marshalling needs, urgent production needs}

[0058] Step 3. Optimal Matrix

[0059] At this stage, there are 4 starting points at 6:30, 7:20, 8:00 and 8:30. 0, and the statistics of each train are shown in Table 1 (take v S =6km / h).

Abstract

The invention discloses a quantization method for determining the disintegration order of a train by an industrial marshalling station. Based on the principle and method of fuzzy mathematics, a quantitative method is proposed to describe the process of optimizing the disassembling trains in the industrial marshalling yard. Aiming at each characteristic index parameter of the optimization matrix inthe fuzzy analysis process, by combining with the practical work of the industrial marshalling yard, the quantitative analysis is carried out theoretically, and a set of quantitative model describingthe characteristic index parameter is put forward. The method of the invention has the advantages of simple steps, convenient operation and being capable of optimizing the train disassembly sequence,and the result is closer to reality objectively, thereby improving the scientificity and effectiveness of the work, having strong practicability, being good in use effect and being convenient to be popularized and used.

Description

technical field [0001] The invention belongs to the field of industrial marshalling station management information system (MIS), in particular to a quantitative method for determining the dismantling sequence of industrial marshalling station trains. Background technique [0002] The determination of the dismantling sequence of industrial marshalling station trains is one of the important contents of the dismantling plan. It mainly considers factors such as arrival time, dismantling time, departure time, marshalling needs, and urgent production needs. Its main functions are as follows: ① No operation disorder; ②When the arrival site is full but the traffic flow is continuous, vacate the arrival line in time to pick up the train; ③Make the vehicles in the station go out as soon as possible and meet the traffic demand of the departure train to the greatest extent; ④Guarantee the minimum inventory of goods required for normal production quantity. The shunting operation in indu...
