In many contexts, logistics is used to enable competitive advantages and cost savings. For some companies, logistics itself is its core competency (i.e. logistics providers). In this context, vendor-managed inventory (VMI) systems are one of the most up-to-date strategies allowing companies to reach a superior performance. Under a VMI strategy, the replenishment and distribution making process ...

Most common feature ranking methods are based on the statistical approach. This paper compare several statistical methods with new method for feature ranking derived from data mining process. This method ranks features depending on percentage of child units that survived the selection process. A child unit is a processing element transforming the parent input features to the output. After train...

When de Sitter first introduced his celebrated spacetime, he claimed, following Schwarzschild, that its spatial sections have the topology of the real projective space IRP 3 (that is, the topology of the group manifold SO(3)) rather than, as is almost universally assumed today, that of the sphere S. (In modern language, Schwarzschild was disturbed by the non-local correlations enforced by S geo...

many ranking methods have been proposed so far. however, there is yet no method that can always give a satisfactory solution to every situation; some are counterintuitive, not discriminating; some use only the local information of fuzzy values; some produce different ranking for the same situation. for overcoming the above problems, we propose a new method for ranking fuzzy quantities based on ...

in this paper, for the first time, blood inventory-routing problem (irp) is defined and a mixed integer linear programming formulation is presented. to do so, the concepts of assigned inventory, transfusion to crossmatch ratio, crossmatch release period, older-first policy and order-up-to level inventory policy along with perishability considerations are incorporated into the latest inventory-r...

BACKGROUND Although interpretive performance varies substantially among radiologists, such variation has not been examined among mammography facilities. Understanding sources of facility variation could become a foundation for improving interpretive performance. METHODS In this cross-sectional study conducted between 1996 and 2002, we surveyed 53 facilities to evaluate associations between fa...

In our previous study, focusing on a ranking determination, we developed two ranking models. The foundation of these ranking models is derived from either one of the two ranking methods, denoted by Ranking (I) and Ranking (II), that were proposed in our previous papers. The purpose of this paper is to analyze the mathematical structure in the process of generating Ranking (I) and Ranking (II) i...

Archaeology is a visually rich discipline with a long history of utilising images across a variety of contexts within its practice. However, due to the often unavoidably subjective nature of visual interpretation, fundamental issues with its application remain problematic and largely unresolved. Furthermore, in recent years the rising dominance of digital techniques for archaeological threedime...

Background In an effort to change drinking and driving behaviour and reduce the number of serious crashes attributable to alcohol, in the spring of 2010 the Government of British Columbia, Canada announced new measures to deal with drinking drivers. Aim This paper presents evidence of the impact of new immediate roadside prohibitions (IRP) for drinking drivers as assessed by random roadside sur...

In this paper, we analyse and seek to understand the complex relations that occur between clients and consultants during consulting projects. The paper uses ideas from Schön’s model of the “reflective practitioner” to propose a new model conceptualising the client-consultant team as a community of interpretive communities. We show that client and consultant belong to different interpretive comm...
