This paper describes a polynomial-time heuristic for the permutation flow-shop scheduling problem with the criterion of minimizing total completion time. The proposed method consists of two phases: arranging the jobs in priority order and then constructing a sequence. A new ranking method is employed to prioritize the jobs for incorporating into the construction phase of the heuristic. Computat...

* This value represents an average weighted score of the environmental issues associated to the concern. For further details see Detailed scoring tables (Annex II). ** This value represents the overall score including environmental, socio-economic and likely future impacts. For further details see Detailed scoring tables (Annex II). *** Priority refers to the ranking of GIWA concerns. Increased...

The goal of the presented work is to provide support for software requirements engineering domain experts in modeling combinatorial optimization problems that arise in requirements prioritization and release planning. A Domain-Specific Language (DSL), called reqT/CSP, is presented that integrates constraints modeling with requirements modeling. The DSL is embedded in the object-functional Scala...

The problem of ranking is to predict or to guess the ordering between objects on the basis of their observed features. In this paper we consider ranking estimators that minimize the empirical convex risk. We prove generalization bounds for the excess risk of such estimators with rates that are faster than 1 √n . We apply our results to commonly used ranking algorithms, for instance boosting or ...

BACKGROUND The spread of antibiotic-resistant bacteria poses a substantial threat to morbidity and mortality worldwide. Due to its large public health and societal implications, multidrug-resistant tuberculosis has been long regarded by WHO as a global priority for investment in new drugs. In 2016, WHO was requested by member states to create a priority list of other antibiotic-resistant bacter...

Membrane technologies for the separation of mixtures have gained an extensive worldwide attraction in the modern industrialized world. They have many industrial and medical applications such as water desalination, wastewater reclamation, gas separation, food and medical applications. However, even though all these applications have their own efficiency and market, the selection of priority appl...

the world health organization’s (who’s) world health report 2010, “health systems financing, the path to universal coverage,” promoted universal health coverage (uhc) as an aspirational objective for country health systems. yet, in addition to the dimensions of services and coverage, distribution of coverage in the population, and financial risk protection highlighted by the report, the conside...

the paper presents a multi-factor decision-making approach for prioritizing failure modes as an alternative to traditional approach of failure mode and effect analysis (fmea). the approach is based on the ‘technique for order preference by similarity to ideal solution’ (topsis). the priority ranking is formulated on the basis of six parameters (failure occurrence, non-detection, maintainability...

abstract: although all university majors are prominent and the necessity of their presences is of no question, they might not have the same priority basis considering different resources and strategies that could be spotted for a country. this paper focuses on clustering and ranking university majors in iran. to do so, a model is presented to clarify the procedure. eight different criteria are ...

OBJECTIVE To comparatively evaluate the three most widely used ambulance stretcher loading systems; easi-loader, ramp/winch and tail lift to identify a preferred system based on safety and usability evidence. METHODS Three data types were collected in the field, the laboratory and from a national questionnaire. Field data were collected using the qualitative methods of observation (link analy...
