TL;DR: In this article, the authors developed a measurement scale for relationship quality in procurement, which provides a management tool for agribusiness companies to evaluate their supply chain basis based on satisfaction, trust, and commitment.
Abstract: In this paper we develop a measurement scale for relationship quality in procurement which provides a management tool for agribusiness companies to evaluate their supply chain basis. In agribusiness, processors are often confronted with thousands of small farmer-suppliers. According to findings from several research streams, we argue that relationship quality must be conceptualised as a construct comprising satisfaction, trust, and commitment. We test our model for the German dairy and pork chains, thereby providing new insights into the critical success factors of initiating and maintaining relationships with agricultural suppliers. Relationship quality is determined by a number of factors. Though there are differences between the industries in question, we find some parallels in the factors explaining relationship quality. It is surprising that farmer orientation of the processor and perception of management competence by the farmer are more important than price satisfaction. Thus, understanding farmers...

TL;DR: While the awareness of economic factors stressing efficiency of e-procurement is a necessary condi- tion for PePP adoption, enabling faster adoption requires considering and addressing political-structural factors that are specific to a particular political and administrative context.
Abstract: E-Procurement is on the political agenda throughout Europe. Den- mark was among the forerunners in Europe, but the adoption of the public e- procurement portal (PePP) has been slow. In this paper, we use the lens of economic and political rationality to discuss and analyze possible explana- tions for slow adoption rates. We find that despite awareness of potential effi- ciency gains of IT in public procurement functions, political-structural factors slow down the adoption process. We suggest that while the awareness of economic factors stressing efficiency of e-procurement is a necessary condi- tion for PePP adoption, enabling faster adoption requires considering and addressing political-structural factors that are specific to a particular political and administrative context.

TL;DR: The results show that the proposed algorithm (OPT-ORS) achieves a good balance between the procurement cost and the user QoE for cloud-based VSPs and guarantees that reserved VM instances are fully utilized to satisfy the baseline user demand.
Abstract: The emergence of cloud computing provides a cost-effective approach to deliver video streams to a large number of end users with the desired user quality of experience (QoE). Under such a paradigm, a video service provider (VSP) can launch its own video streaming services virtually by renting the distribution infrastructure from one or more cloud service providers (CSPs). However, CSPs such as Amazon EC2 normally offer multiple pricing options for virtual machine (VM) instances that they can provide, such as on-demand instances, reserved instances, and spot instances. Such diverse pricing models make it challenging for a VSP to determine how to optimally procure the required number of VM instances in different types to satisfy dynamic user demands. Given the limited budget, a VSP needs to carefully balance the procurement cost and the achieved QoE for end users. In this paper, we investigate the tradeoff between the cost incurred by VM instance procurement and the achieved QoE of end users under Amazon EC2's pricing models, and formulate the VM instance provisioning and procurement problem into a constrained stochastic optimization problem. By applying the Lyapunov optimization framework, we design an online procurement algorithm, which approaches the optimal solution with explicitly provable upper bounds. We also conduct extensive trace-driven simulations and our results show that our proposed algorithm (OPT-ORS) achieves a good balance between the procurement cost and the user QoE for cloud-based VSPs. In the achieved near-optimal situation, our algorithm guarantees that reserved VM instances are fully utilized to satisfy the baseline user demand, on-demand VM instances are only rented to handle flash crowds, while more spot VM instances are rented than on-demand VM instances to serve user demand over the baseline due to their low prices.

TL;DR: In this article, the authors investigated the hypothesis that different supply channels impose different types (and levels of) transaction costs on beef processors in the United Kingdom, and the choice of supply channel is therefore influenced by these transaction costs.
Abstract: This article investigates the hypothesis that different supply channels impose different types (and levels of) transaction costs on beef processors in the United Kingdom. The choice of supply channel is therefore influenced by these transaction costs. Recent food safety legislation and increasing consumer concerns over farm animal welfare may have altered the transaction costs arising from different supply channels. Conjoint analysis is used to measure the relative importance of selected transaction costs in a processor's procurement decision. A survey of UK beef processing firms is used to collect data for the conjoint analysis. The results suggest that the monitoring costs arising from the traceability of cattle to the farm of origin are particularly important. The implications for vertical coordination in the beef marketing chain are discussed. © 1996 John Wiley & Sons, Inc.
