15 Mar 2013TL;DR: In this paper, a computer-implemented process receives a request to utilize one or more virtual data center (VDC) resources at a virtual data centre and determines a particular service level applicable to request.
Abstract: A computer-implemented process receives a request to utilize one or more virtual data center (VDC) resources at a virtual data center and determines a particular service level applicable to request. Based on the particular service level and mapping information that indicates associations between VDC resource utilization policies and service levels, the process determines a particular VDC resource utilization policy corresponding to the request and causes completion of the request according to the particular VDC resource utilization policy. Another process determines that a resource utilization performance is incompatible with a requested service level and selects a new resource utilization based in part on the resource utilization performance information and mapping information. The process causes data distributed according to a prior resource utilization policy to be distributed according to the new resource utilization policy in one or more resources at a virtual data center.

TL;DR: This research extends the guaranteed service model of safety stock placement to allow random lead times and demonstrates the demonstration of real stochastic lead times in practice and discusses how this approach outperforms more traditional heuristics that either ignore lead-time variability or consider the maximum lead time at each stage.
Abstract: Effective end-to-end supply chain management and network inventory optimization must account for service levels, demand volatility, lead times, and lead-time variability. Most inventory models incorporate demand variability, but far fewer rigorously account for lead-time variability, particularly in multiechelon supply chain networks. Our research extends the guaranteed service model of safety stock placement to allow random lead times. The main methodological contribution is the creation of closed-form equations for the expected safety stock in the system; this includes a derivation for the early-arrival stock in the system. The main applied contributions are the demonstration of real stochastic lead times in practice and a discussion of how our approach outperforms more traditional heuristics that either ignore lead-time variability or consider the maximum lead time at each stage.

TL;DR: In this article, the authors evaluate the implementation of the service profit chain as an entrepreneurial marketing initiative within a defined franchise system, primarily based on initiatives of retention, related sales and referrals, and evaluate these initiatives against service quality dimensions.
Abstract: Purpose – The purpose of this paper is to evaluate the implementation of the service profit chain as an entrepreneurial marketing initiative within a defined franchise system. An objective is also to evaluate these initiatives against service quality dimensions. Despite recognition of the merits and advantages of service profit chain initiatives of retention, related sales and referrals, little research has empirically addressed the perceptions of franchisees regarding these initiatives.Design/methodology/approach – Methodology includes the empirical analysis of evaluating the effectiveness of service profit chain implementation, primarily based on initiatives of retention, related sales and referrals. Research methodology comprises the survey approach, using electronic media and Surveypro analysis. This is facilitated by descriptive and inferential statistical techniques using SPSS version 11.0 data analysis. Inferential significance tests include the ANOVA Kruskal‐Wallis hypothesis test; and the Cronbac...

TL;DR: This document specifies protocol mechanisms to enable the efficient and accurate measurement of performance metrics for packet loss and one-way and two-way delay in MPLS networks.
Abstract: Many service provider service level agreements (SLAs) depend on the
ability to measure and monitor performance metrics for packet loss and
one-way and two-way delay, as well as related metrics such as delay
variation and channel throughput. This measurement capability also
provides operators with greater visibility into the performance
characteristics of their networks, thereby facilitating planning,
troubleshooting, and network performance evaluation. This document
specifies protocol mechanisms to enable the efficient and accurate
measurement of these performance metrics in MPLS networks. [STANDARDS-

TL;DR: A continuous review (Q, r) stock-control system is considered, where the order points and lot sizes are computed simultaneously and interesting relations between shortage costs and service levels can be viewed for different sets of other inventory parameters.
Abstract: In a practical situation it is often difficult to determine the value of the shortage costs for use in in ventory-control systems. However, in cost-minimization problems including service-level constraints, shortage costs are implicitly prevailing. With the purpose of exploring these relations, a continuous review (Q, r) stock-control system is considered, where the order points and lot sizes are computed simultaneously. Instead of explicitly expressing the shortage cost in the objective function, it is taken into consideration through a service-level constraint. The shadow price of this constraint can in some sense be interpreted as the shortage cost corresponding to the requested service level. By changing the value of the service level, interesting relations between shortage costs and service levels can be viewed for different sets of other inventory parameters. In order to investigate the sensitivity for probabilistic variations in the input data, two different probability distributions are used to describe the lead-time demand.
