    An artificial neural network case study: The control of work-in-process inventory in a manufacturing line
    Col, M; Karlik, B
    In manufacturing systems, the cost of stock, which constitutes a significant portion of the total cost, is one of the important costs that has to be dealt with by the managers, The problem of inventory is encountered in cases where accumulation of physical materials is needed for the purpose of meeting the demand of raw materials, work in process and finished goods in a specific period. Work-in-process, between the stages of manufacturing process comes up because of the high rate of flow of raw materials or finished products and insufficient number of labor-machines at work stations, However, work-in-process can be reduced in a manner that does not hinder the process by determining the optimum number of labor-machine according to the process time. Thus, costs of work-in-process become minimum. In this study work in process at a middle-scale shoe factory is investigated, At the manufacturing center, there are five work departments composed of Cutting, Sewing, Hand-leather Working, Assembling and Quality Control-Packing. these In departments there are work in process because of different processing times and insufficient number of labor-machines. Artificial Neural Network (ANN) with backpropagation is used for solving this work-in-process problem, In the study, optimum number of labor-machines at work stations were obtained for work-in-process without hindering the production by considering processing times and flow at these work stations.

    Phenomenon: Physician immigration from other countries is increasing as developed countries continue to be desirable destinations for physicians; however, the determinants of Turkish physicians' migration decisions are still unclear. Despite its wide coverage in the media and among physicians in Turkiye, and being the subject of much debate, there is insufficient data to justify this attention. With this study, we aimed to investigate the tendency of senior medical students in Turkiye to pursue their professional careers abroad and its related factors. Approach: This cross-sectional study involved 9881 senior medical students from 39 different medical schools in Turkiye in 2022. Besides participants' migration decision, we evaluated the push and pull factors related to working, social environment and lifestyle in Turkiye and abroad, medical school education inadequacy, and personal insufficiencies, as well as the socioeconomic variables that may affect the decision to migrate abroad. The analyses were carried out with a participation rate of at least 50%. Findings: Of the medical students, 70.7% had emigration intentions. Approximately 60% of those want to stay abroad permanently, and 61.5% of them took initiatives such as learning a foreign language abroad (54.5%) and taking relevant exams (18.9%). Those who wanted to work in the field of Research & Development were 1.37 (95% CI: 1.22-1.54) times more likely to emigrate. The push factor that was related to emigration intention was the working conditions in the country (OR: 1.89, 95% CI: 1.56-2.28) whereas the social environment/lifestyle abroad was the mere pull factor for the tendency of emigration (OR: 1.73, 95% CI: 1.45-2.06). In addition, the quality problem in medical schools also had a significant impact on students' decisions (OR: 2.20, 95% CI: 1.83-2.65). Insights: Although the percentage of those who want to emigrate definitely was at the same level as in the other developing countries, the tendency to migrate permanently was higher in Turkiye. Improving working conditions in the country and increasing the quality of medical faculties seem vital in preventing the migration of physicians.
