Problems solved by technology

However, most of the research is out of touch with the production site, and the on-site interference information that affects the execution of dispatching instructions cannot be fed back to the dispatching system in time, which will lead to the accumulation and expansion of errors in dispatching results

Embodiment Construction

[0073] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0074] A mold workshop scheduling method based on real-time production data collection, its specific implementation is as follows:

[0075] Step 1. Determine the objective function for job scheduling in the die shop.

[0076] Mold manufacturing is characterized by different cycle lengths, different product types, and heavy tasks. Once an order is signed, meeting the delivery date required by the customer and minimizing production costs are the most important goals. Only in this way can the economic efficiency of the enterprise be improved. Therefore, the completion time F 1 Minimize and total production cost F 2 Minimize the factor as the objective function; where F 2 Including equipment processing costs, staff costs and raw material costs;

[0077] F 1 = min ( Σ ...

Abstract

The invention provides a mold workshop scheduling method based on real-time production data collection. The method comprises the following steps of (1) determining an objective function of mold workshop job scheduling, and using completion time F1 minimization and total production cost F2 minimization as factors of the objective function; (2) obtaining parameters required by the objective function in the step (1) through statistics in advance and a workshop production field real-time data collection and feedback method; (3) achieving mold workshop scheduling on the basis of a BBO algorithm, enabling a scheduling scheme to correspond to habitats in the BBO algorithm, and using devices to be scheduled, workers to be scheduled and workpieces to be machined as decision variables, wherein each decision variable is a suitability degree variable SIV of the corresponding habitat, and the objective function value obtained through the decision variables is a suitability degree index HSI; (4) conducting rescheduling when devices break down. According to the mold workshop scheduling method based on real-time production data collection, production efficiency can be effectively improved, the production period is shortened, and it is ensured that production can be carried out smoothly.

Description

technical field [0001] The invention relates to a workshop production control method, in particular to a mold workshop scheduling method based on real-time production data collection. Background technique [0002] Mold is the basic process equipment of industrial production, known as the "mother of modern industry", and is an important part of my country's national economy. In the typical order-oriented single-piece multi-variety manufacturing industry of mold companies, the arrival of orders is random, and there are many uncertainties in the production process. Therefore, how to ensure the quality of molds with the lowest cost and shortest production cycle, Delivering molds to customers is the main issue in the study of workshop scheduling in the mold manufacturing industry. The workshop scheduling problem is a typical NP-hard problem, and it is of great significance for enterprises to find a scheduling scheme that meets the actual production needs. [0003] At present, t...
