The success of a supply chain is highly dependent on selection of best suppliers. These decisions are an important component of production and logistics management for many firms. Little attention is given in the literature to the simultaneous consideration of cardinal and ordinal data in supplier selection process. This paper proposes a new integrated data envelopment analysis (DEA) model whic...

Supplier selection in supply chain is a multi-criteria problem that involves a number of quantitative and qualitative factors. This paper deals with a concrete problem of flour purchase by a company that manufactures bakery products and the purchasing price of flour depends on the quantity ordered. The criteria for supplier selection and quantities supplied by individual suppliers are: purchase...

It is widely acknowledged that suppliers contribute positively to innovation in new product development. However, it remains rather unclear what suppliers actually contribute to innovation. Based on a literature review focusing on 80 articles, and a focus group meeting with strategic purchasing managers, a conceptual framework is developed categorizing different supplier inputs to innovation. T...

Locality Preserving Projections (LPP) is a widely used manifold reduced dimensionality technique. However, it suffers from two problems: (1) Small Sample Size problem; (2)the performance is sensitive to the neighborhood size k. In order to address these problems, we propose an Exponential Locality Preserving Projections (ELPP) by introducing the matrix exponential in this paper. ELPP avoids the...

(Dated: November 21, 2008) Abstract Locality Preserving Projections(LPP) is a recently developed linear feature extraction algorithm, which has been frequently used in the task of face recognition and other applications. However, LPP does not satisfy the shift invariance property, which should be satisfied by a linear feature extraction algorithm. In this paper, we analyze the reason and derive...

The subspace transformation plays an important role in the face recognition. LPP, which is so-called the Laplacianfaces, is a very popular manifold subspace transformation for face recognition, and it aims to preserve the local structure of the samples. Recently, many variants of LPP are proposed. LPP is a baseline in their experiments. LPP uses the adjacent graph to preserve the local structur...

Purpose To study the learning processes and mechanisms involved in sustainability-oriented supplier development (SSD), including how knowledge is transmitted by buyer it received, understood internalised supplier. Design/methodology/approach An exploratory longitudinal multi-case approach adopted. The research context a social SSD project focusing on occupational health safety (OHS) management ...

The objective of this work is to study optimal Vendor-Managed Inventory policies in distributions systems in which demand and delivery processes are characterized by a discreteevent dynamics. In Vendor-Managed Inventory policies, the supplier organizes the deliveries to the customer in order to satisfy its demand by minimizing transportation costs and holding costs of the customer. In the consi...

BACKGROUND Lysophosphatidic acid (LPA) is a signalling phospholipid with multiple biological functions, mainly mediated through specific G protein-coupled receptors. Aberrant LPA signalling is being increasingly implicated in the pathology of common human diseases, such as arteriosclerosis and cancer. The lifetime of the signalling pool of LPA is controlled by the equilibrium between synthesizi...

We investigated the spatial and temporal evolution of temperature and electron density associated with femtoand nanosecond laser-produced plasmas (LPP) from brass under similar laser fluence conditions. For producing plasmas, brass targets were ablated in vacuum employing pulses either from a Ti:Sapphire ultrafast laser (40 fs, 800 nm) or from a Nd:YAG laser (6 ns, 1064 nm). Optical emission sp...
