Elektronik kart üretiminde hat atama problemi için süreç akışını dikkate alan bütünleşik bir yaklaşım

The efficient operation of electronic cards, which are used as a subcomponent in many products such as telephones, televisions, computers, automobiles and smart devices, depends on appropriate design, production and quality. High product variety in production processes, production capacity constraints and setup times in model changes can result in non-value-added intermediate operations and lead times, resulting in inefficiency. This study proposes an effective approach to the line assignment problem for electronic board production addressing efficiency increase and cost reduction. The resulting production plan, which will provide the highest production amount of electronic cards in different assembly and testing lines, considers different characteristics of electronic cards (e.g., bill of materials, common component use, number of components, demand, operation times and process flow). The PCB line assignment problem, which is in the NP-hard problem class, was solved by clustering analysis and a 0-1 mixed integer mathematical model. The results of the model were analyzed with a simulation model that models the operation of the production line. In the application made with real data, 22% improvement was achieved in the production amount compared to the current situation by using the proposed approach. The proposed approach can be applied to the scheduling of an electronic board manufacturer with multiple surface mount technology (SMT) assembly lines, multiple process flows, and multiple testing stations.
