In the competitive market of B2B e-commerce website, as customer switching cost and network externality could prevent customers to switch to later entrant, the earlier entrant has the advantage to build and retain its market share. However, the declining cost of information technology (IT) over time provides the later entrant a cost advantage. In order to maintain competitive advantage, what sh...

Cloud manufacturing is defined as a relationship between the consumer and a flexible array of production services, managed by an intervening architecture that can match service providers to product and manufacturing processes Cloud manufacturing definitions typically make explicit or imply three groups of actors: consumers, who request and use cloud manufacturing processes; application provider...

machine-part family formation is one of major applications of group technology (gt). the machine cell formation problem in cellular manufacturing system (cms) involves the decomposition of the manufacturing system into machine cells. part families are identified such that they are fully processed within a machine cell. the problem of cell design is a very complex task with wide ranging implicat...

We analyze industrial espionage in the context of entry deterrence. We consider a monopoly incumbent, who may expand capacity to deter entry, and a potential entrant who owns an inaccurate Intelligence System. The Intelligence System generates a noisy signal on incumbent's actions and the potential entrant decides whether to enter based on this signal. If the precision of the Intelligence Syste...

This paper presents a model and analysis of a reentrant production line with finite buffers and unreliable machines. Semiconductor device and liquid crystal display (LCD) fabrication processes are characterized as a re-entrant process, in which a similar sequence of processing step is repeated several times. The purpose of this paper is to present mathematical formulations and algorithms to ana...

Real-time scheduling of semiconductor manufacturing operations, semiconductor test operations in particular, is complicated due to the following factors; multi-head resources, multi-level hardware dependency, temperature and hardware criteria, dynamic determination of processing time and indexing time, batch processing and re-entrant flow. A first-ofits-kind, object oriented (OO), discrete even...

The subject of this paper is open multiclass queueing networks, which are common models of communication networks, and complex manufacturing systems such as wafer fabrication facilities. We provide sufficient conditions for the existence of bounds on long-run average moments of the queue lengths at the various stations, and we bound the rate of convergence of the mean queue length to its steady...

The proposed methodology has been implemented in modular system architecture to avoid deadlock situations in real time using a rule base approach. A system configuration consisting of work centers, buffers, robots, and loading/unloading stations is taken with limited capacities as the example case study. A part mix with a variety of processing sequences such as, re-entrant only, jig-jag, re-ent...

We propose an approximate approach for estimating the performance measures of the re-entrant line with single-jobmachines and batch machines based on the mean value analysis (MVA) technique.Multi-class jobs are assumed to be processed in predetermined routings, in which some processes may utilize the same machines in the re-entrant fashion. The performance measures of interest are the steady-st...
