Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of household appliances, and in particular to a production scheduling method and system for small household appliances. Background Art
[0002] At present, in the manufacturing of modern small household appliances, small household appliance production scheduling refers to the process of allocating small household appliance production tasks to production resources, among which there are many ways to allocate production tasks to production resources, such as introducing different types of products (such as toasters, electric kettles and other small household appliances) through the production line at each moment for production. The efficient operation of the production line, product quality and equipment stability are key factors for enterprises to maintain competitiveness, improve production efficiency and reduce costs. However, in the actual production process, production lines often face multiple challenges: frequent equipment failures, fluctuations in production efficiency, and unstable product quality may lead to uneven product quality, affecting customer experience and brand image. Traditional scheduling methods are often based on experience or fixed production plans, and fail to comprehensively consider three aspects such as equipment failures, production efficiency and production quality, resulting in difficulty in maximizing the overall efficiency of the production line. Therefore, how to determine the most suitable small household appliance scheduling method at the current moment has become the most important key at present.
[0003] However, the existing small household appliance production scheduling method and system only solve the problem of unreasonable production planning of existing manual arrangement of household appliances and the problem of affecting the production efficiency of household appliances. However, this method only considers the production efficiency, and does not consider the comprehensive equipment failure, production efficiency and production quality. It determines the best scheduling method for small household appliances that is most suitable for the current moment, but cannot solve the problems of frequent equipment failures and unstable product quality. For example, the patent with the publication number of "CN114548660A" and the name of the patent is "Production Scheduling Method, Device, Equipment and Storage Medium for Household Appliances", and the method includes the following steps: obtaining production data, the production data includes work calendar information, line information, whole machine model information, material information, mold information and order information of orders to be produced; constructing a production scheduling model based on the production data, the production scheduling model includes decision variables, constraints and objective functions, the constraints are determined based on the production data, and the conditions that limit the scope of the decision variables, and the objective function is a functional relationship established based on the order delivery period, order delay amount and production capacity as the target; optimizing the objective function until the value of the objective function reaches the minimum value; determining the decision variable corresponding to the minimum value as the production scheduling data and outputting it. However, this patent only solves the problem that the existing manual production plan of household appliances is unreasonable and affects the production efficiency of household appliances, but this method only considers the production efficiency, and does not consider the comprehensive equipment failure, production efficiency and production quality, and determines the best scheduling method for small household appliances at the current moment.
[0004] Therefore, the present invention proposes a small household appliance production scheduling method and system. Summary of the invention
