this paper deals with a multi-period fixed charge production-distribution problem associated with backorder and inventories. the objective is to determine the size of the shipments from each supplier and backorder and inventories at each period, so that the total cost incurred during the entire period towards production, transportation, backorder and inventories is minimised. a 0-1 mixed intege...

At the University of Kansas, we are collecting cases and advice and making it available by computer. The software, Fabrication error Indexed eXamples and Solutions (FIXS), is a knowledge-based system to provide quick, possible solutions to fabrication errors suitable for use by multiple DOTs. The sharable database can lead to standardized solution procedures that would expedite bridge fabricati...

 Based on some stationary periodic solutions and stationary soliton solutions, one studies the general solution for the relative lax system, and a number of exact solutions to the Korteweg-de Vries (KdV) equation are first constructed by the known Darboux transformation, these solutions include double and triple singular periodic solutions as well as singular soliton solutions whose amplitude d...

abstract: antibiotics are a valuable addition to health practitioners for the management of bacterial infections. during endodontic treatment and when managing trauma to the teeth, antibiotics may be applied systemically or locally. due to the potential risk of adverse effects of systemic applications, and the ineffectiveness of systemic prescribed antibiotics in necrotic or pulpless teeth and ...

in 2d soccer simulation league, agents will decide based on information and data in their model. effective decisions need to have world model information without any noise and missing data; however, there are few solutions to omit noise in world model data; so we should find efficient ways to reduce the effect of noise when making decisions. in this article we evaluate some simple solutions whe...

nanofiltration-based separation processes have found diverse applications in industrial and environmentalproblems recently, due to several advantages such as lower energy requirement and elevated flux ratescompared with their reverse osmosis (ro) counterparts. several attempts have been made for modellingnf-based separation processes ranging from rigorous space-charge approaches to simpler irre...
