Combining multi-class works and inventory models for performance analysis of multi-product manufacturing logistics chains Yifan Wu & Ming Dong Received: 15 October 2006 /Accepted: 6 March 2007 /Published online: 31 March 2007 # Springer-Verlag London Limited 2007 Abstract Manufacturing logistics chains consist plex interconnections among several suppliers, manufacturing facilities, warehouses, retailers and logistics providers. Performance modeling and analysis e increasingly more important and difficult in the management of plex manufacturing works. Many research studies have developed different methods to solve such problems. However, most of the research focuses on logistics systems with either a single stage or single type of product. In the real world, industries always involve multiple stages and produce multiple types of products at one stage. This paper is geared toward developing a new methodology bining multi-class works and inventory models for the performance analysis of multi-product manufacturing logistic chains. work of multi-class inventory queue models is presented for the performance analysis of a serial multi-stage manufacturing logistics chain in which multiple types of products are produced at each stage. A job queue position strategy is employed to analyze the major performance measures and an approach for aggregating input streams and separating outp
