In an era where people in the world are concerned about environmental issues, companies must reduce distribution costs while minimizing pollution generated during process. For today’s multi-depot problem, a mixed-integer programming model is proposed this paper to minimize all incurred entire transportation process, considering impact of time-varying speed, loading, and waiting time on costs. T...

Inter-hospital transfers of patients for different elements of care have been increasingly used as a common strategy for providing quality healthcares through sharing limited resources worldwide. In this paper, the authors study the problem of healthcare delivery operations for inter-hospital patient transfers motivated by a real-world case within the South East Local Health Integration Network...

Performance problem diagnosis is a critical part of network operations in ISPs. Service providers typically deploy monitoring nodes at several vantage points in their network, to record end-to-endmeasurements of network performance. Network operators use these measurements offline; for example, to troubleshoot customer complaints. In this work, we leverage such monitoring infrastructure deploym...

OBJECTIVE To identify continuation rates of depot medroxyprogesterone acetate (Depo-Provera) and characteristics of long-term users in a population of inner-city, minority adolescents with high pregnancy rates. DESIGN Retrospective medical record review. SETTING An inner-city adolescent clinic and an adolescent pregnancy program. METHODS A review of the medical records of 250 females aged...

CO2 reduction from transportation is exerting significant effects on global reduction. This industry contributes 23.96% of emissions. In this research, an ecological network input–output interval fuzzy linear programming (EIFP) method developed to clarify responsibilities and depict transfer relationships transportation. integrates analysis (IOA), inexact rough (IRFLP) (ENA) into a general fram...

An efficient iterative Earth Mover’s Distance (iEMD) algorithm for visual tracking is proposed in this paper. The Earth Mover’s Distance (EMD) is used as the similarity measure to search for the optimal template candidates in feature-spatial space in a video sequence. The computation of the EMD is formulated as the transportation problem from linear programming. The efficiency of the EMD optimi...

When Uppsala University Library was formally founded in 1620 and 1621, the book depot of Crown, previously located on Gråmunkeholmen (today’s Riddarholmen) Stockholm, donated there. This collection inter alia contained confiscated library a Swedish nobleman remnants from medieval monastery libraries. As Otto Walde conclusively proved 1915, it also parts King Sigismund (Sigismund III Poland), wh...

Abstract In recent years, operations research in agriculture has improved the harvested yield, reduced cost and time required for field operations, maintained economic environmental sustainability. The heuristics method, named Evolutionary neighborhood discovery algorithm (ENDA), is applied to minimize inter-field intra-field distance of routing planning machines multiple agricultural fields. p...
