Push and Pull Systems
Data broadcasting has emerged as an efficient way for the dissemination of information over asymmetric wireless environments where the needs of the various users of the data items are usually overlapping. In such environments, data broadcasting stands to be an efficient solution since the broadcast of a single information item is likely to satisfy a possibly large number of users. Communication...
متن کاملPush-pull farming systems.
Farming systems for pest control, based on the stimulo-deterrent diversionary strategy or push-pull system, have become an important target for sustainable intensification of food production. A prominent example is push-pull developed in sub-Saharan Africa using a combination of companion plants delivering semiochemicals, as plant secondary metabolites, for smallholder farming cereal production...
متن کاملA push-pull queueing system
We consider a two node multiclass queueing network given by two machines each with two classes. There are two streams of jobs: One stream originates in machine 1, which feeds it for further processing to machine 2, and the other stream moves in the opposite direction. We describe a policy for this system which is stable and which keeps both machines busy at all times. We obtain explicit express...
متن کاملPush Vs . Pull : the Case
Purchase shares of major national-brands in consumer packaged-goods industries vary substantially across stores, both between markets and within markets. This paper measures the extent to which this variation in national-brand purchase shares depends on store-specific supply decisions, which are traditionally within the purview of trade marketing. We first demonstrate the extent to which purcha...
متن کاملPush-Pull Partial Covering Problems
This paper considers a bicriteria model to locate a semi-obnoxious facility within a convex polygon, while employing Euclidean push and pull covering criteria. The partial covering context is introduced into an ordinary bicriteria location framework. Although both objectives are neither concave nor convex, low complexity polynomial algorithms to find the efficient solutions and the tradeoffs in...
