This paper describes an order release and loading technique, which considers the routing as well as the machine flexibility of a modern job shop production. The workload control approach involves three steps. In a first step 'lead orders', i.e. urgent production orders that are either processed on a known bottleneck or are of high value, are identified. Afterwards transfer batches of the lead part types are calculated using the aspired machine time as a control parameter. This parameter defines an adequate processing time of a machining center before it is set up for a new job. Finally, the bottom-line workload of the machining centers is determined by allocating and sequencing transfer batches. The procedure is tested by a simulation program that replicates the performance of the production facility of a machine manufacturer, consisting of a Flexible Manufacturing Cell that is embedded into a job shop production for heavy parts.
This paper analyzes North-South technology transfers in a model of oligopolistic competition and spatial product differentiation. Two firms in the North supply a high-tech good and a technically related low-tech good.They decide about licensing the low-tech good to suppliers in the South.With the license Southern firms get access to technology from the North, which enables them-with a certain probability-to enter the market for the high-tech good. Northern firms may therefore license strategically to influence the competitive environment in the high-tech market. In this setting, multiple equilibria with and without licensing may arise, and the resulting outcomes may be inefficient from the viewpoint of the Northern firms.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
