‎A common approach to determine efficient solutions of a multiple objective optimization problem‎ ‎is reformulating it to a parameter dependent scalar optimization problem‎. ‎This reformulation is called scalarization approach‎. Here, a well-known scalarization approach named Pascoletti-Serafini scalarization is considered‎. First, some difficulties of this scalarization are discussed and then ...

in a robust parameter design (rpd) problem, the experimenter is interested to determine the values of con-trol factors such that responses will be robust or insensitive to variability of the noise factors. response sur-face methodology (rsm) is one of the effective methods that can be employed for this purpose. since quality of products or processes is usually evaluated through several quality ...

Introduction: Ius Chasma is a linear trough in western Valles Marineris, formed by horst and graben structures and mass wasting [e.g. 1-6]. Sulfates and other hydrated minerals are found in thin floor deposits, which differs from the thick sulfate-bearing Interior Layered Deposits (ILDs) found in the basinal chasmata, like Capri and Melas. Kieserite (MgSO4 · H2O), a polyhydrated sulfate (PHS), ...

The Internet opens up new markets for businesses and can thus allow for a significant improvement in procurement. However, this will only apply if the customers are able to handle this huge market. In this paper we show that finding optimal suppliers in B2B marketing is a complex combinatorial problem and present a solution to it. The BestBasket system of Mercateo.com helps customers to handle ...

Accurate estimation of spare part demand is challenging in the case intermittent or lumpy demand, characterised by infrequent occurrence and variability size. While prior research has considered effect exogenous variables on there a lack considering effects repair quality aggregated behaviour across fleets assets under influence multiple simultaneously acting drivers failure. This provides new ...
