[Abstract]:In this paper, the production scheduling problem of connectors in multi-variety and small batch mode is studied.In view of some problems and difficulties in the production of connectors in multi-variety and small-batch mode, this paper analyzes and utilizes the DBR method of constraint theory, and establishes the production scheduling problem model of connectors based on constraint theory, and solves it.The model takes into account the actual constraints such as assembly constraints, process constraints, delivery time constraints and so on in the production of connectors. By using the DBR method, the "bottleneck resources" in production are scheduled first, according to the concept of combination of push and pull in constraint theory.In order to improve the production efficiency and the order fulfillment rate of the whole system, the production before and after the bottleneck is carried out respectively, the pull production, the push production and the delivery buffer are set behind the assembly link.The main research contents of this thesis include: (1) the main production planning model based on the characteristics of the connector based on constraint theory (TOC) is expounded, and the production control method of DBR is explained in detail by combining 9 basic principles.This paper mainly discusses how to use DBR to identify bottlenecks and set buffers for connector production in multi-variety and small-batch production environment.Bottleneck resource scheduling (2) describes the production scheduling problem of connectors with mathematical symbols and three-parameter representation.The manufacturing environment, processing constraints and optimization objectives of connectors are described in detail.On the basis of summarizing the characteristics of the production scheduling problem in the multi-variety and small-batch production mode, the mathematical modeling of the scheduling problem in the multi-variety and small-batch production mode is carried out, and in order to make the mathematical model more close to the actual situation,The mathematical model is supplemented to a certain extent, and the problem model is solved in advance preparation for the establishment of the dispatching system.Combined with the DBR method in the constraint theory, the bottleneck resources in the connection machine production are sorted out: the semi-finished product production in front of it is designed into a pull-type production, the assembly production behind it is produced by pushing production, and the production of the semi-finished product in front of the semi-finished product is designed into a pull-type production.At the end of the assembly, the shipping buffer was added.Design and implementation of a series of measures to ensure the production scheduling efficiency and order on time rate of connector production scheduling in multi-variety and small batch mode.Finally, through the research of the connector production scheduling problem under the multi-variety and small-batch mode, the system model is applied to the actual connector production case, which effectively improves the delivery rate of the case order on time, and reasonably controls the inventory.It reduces the cost in the production process and helps to improve the product competitiveness of the company. The feasibility and optimization of the model production scheduling system are verified.
