Abstract
Increasing productivity and efficiency in factories with make-to-order (MTO) production systems have attracted growing interest of academia and industry. In MTO companies, efficient order release and schedule are essential for succeeding in today’s marketplace. However, dynamic demand of customers and constrained resources make it difficult to achieve, as well as limiting the profits. Thus, to overcome the problem of order releasing and multi-item scheduling considering the capacity constrained resources investigated, a heuristic approach is proposed based on the drum-buffer-rope (DBR) method. The proposed heuristic is tested on different types of problems based on due date tightness and demand of products. The performance of the proposed heuristic is compared with other famous heuristic methods in literature. End results indicate that the proposed heuristic based on the DBR method outperforms against the other competitors, and it gives more significant results when optimal buffer size is adopted.
Highlights
In today’s competitive environment, the manufacturing trend has changed from mass production to mass customization
capacity constrained resources (CCR) will be released in the production order release sequence at position q + 1
Computational and are drum buffer rope (DBR) method for the scheduling of customer orders considering CCR resources and buffer The current problem is composed of several design parameters that can affect the in the production shop
Summary
In today’s competitive environment, the manufacturing trend has changed from mass production to mass customization. Most of the literature investigated a time buffer that can control the time of release to produce the products, whereas the production release mechanism of standard parts of the mix model products based on the real time usage rate of the buffer on CCR and demand rate of product models in the planning horizon is significant to determine production order release in each planning horizon for MTO companies This can reduce the production time of customer orders. Due to significant application of DBR, a novel real-time production order release mechanism is presented in the current research to control standard parts of the variety of product models in buffer before CCR in MTO companies in each planning horizon.
