Item Open Access A load-based and due-date-oriented approach to order review release in job shops(Wiley-Blackwell Publishing, 2000) Sabuncuoğlu, I.; Karapınar, H. Y.In this paper, a new order review/release (ORR) method is proposed for shop floor control systems. The proposed method utilizes both job due date and shop load information to improve the effectiveness of the ORR function in production systems. The performance of the new method is compared to those of a few well-known ORR methods under four experimental conditions. The results of extensive simulation experiments indicate that the proposed method is superior with respect to the mean absolute deviation measure. In general, it is also better than existing methods for the other performance measures. Furthermore, we show that the proposed method is more robust to variations in system load and processing times than the other ORR methods examined.Item Open Access OM forum: innovative online platforms: research opportunities(INFORMS: Institute for Operations Research and the Management Sciences, 2020) Chen, Y.-J.; Dai, T.; Körpeoğlu, C. Gizem; Körpeoğlu, E.; Şahin, Ö.; Tang, C. S.; Xiao, S.Economic growth in many countries is increasingly driven by successful startups that operate as online platforms. These success stories have motivated us to define and classify various online platforms according to their business models. This study discusses strategic and operational issues arising from five types of online platforms (resource sharing, matching, crowdsourcing, review, and crowdfunding) and presents some research opportunities for operations management scholars to explore.
