On comparing the performance of primary care providers

In the past few years primary health care has been characterised as central to the development of the National Health Service in the United Kingdom. Furthermore, performance assessment is seen as a way of achieving care of high standards. Performance indicators and targets are being developed to assess primary care providers, and to develop financial incentives. However, the number of studies that have compared the performance of primary care providers is limited and the existing approaches to evaluation are open to improvement.     

Variable sampling inspection for resubmitted lots based on process capability index Cpk for normally distributed items

In this article, a variables sampling inspection plan for resubmitted lot based on the process capability index C_pk is developed for normally distributed items with unknown mean and variance. The three plan parameters, sample size n, critical acceptance value k_a and the number of resubmissions m, are determined simultaneously by minimizing average sample number (ASN) with two conditions specified by the producer and the consumer. The advantages of the proposed resubmitted sampling plan over the variables single sampling plan are also discussed. Tables of plan parameters for selected values of acceptable quality level (AQL), limiting quality level (LQL), producer’s α-risk and consumer’s β-risk are provided and discussed with the help of an application example.     

基于P2P的万维网服务发布和发现机制的研究

目前采用集中式UDDI服务发布和发现机制的万维网服务体系结构存在着缩放性及可靠性差等方面的问题,而P2P是非中心化的分布式网络,具有较好的缩放性和可靠性．因此引入P2P机制来代替传统集中式的UDDI机制来实现万维网中的服务发布和服务发现,提出基于P2P的万维网服务发布和发现机制的模型,并探讨在P2P上万维网服务发布和发现机制的具体实现．     

Synergistic relationships between Analytical Chemistry and written standards

This paper describes the mutual impact of Analytical Chemistry and several international written standards (norms and guides) related to knowledge management (CEN-CWA 14924:2004), social responsibility (ISO 26000:2010), management of occupational health and safety (OHSAS 18001/2), environmental management (ISO 14001:2004), quality management systems (ISO 9001:2008) and requirements of the competence of testing and calibration laboratories (ISO 17025:2004). The intensity of this impact, based on a two-way influence, is quite different depending on the standard considered. In any case, a new and fruitful approach to Analytical Chemistry based on these relationships can be derived.     

Interval censored sampling plans for the gamma lifetime model

In this article, an acceptance sampling procedure for the gamma lifetime model is established under the interval censored test. Both producer and consumer risks are considered to develop the ordinary and approximate sampling plans with grouped data. Some of the proposed sampling plans are tabulated and the use of the tables is illustrated by an example. A sensitivity study is conducted to evaluate the influence of the length of the time interval on the proposed sampling plans.

A model for standardizing human decisions concerning service-contracts management

Increased expectations of today’s customers are causing businesses to offer a variety of warranty contracts for their products. Because of the intense customer contact that takes place during the process of supporting a contract, the planning for contracts has to not only contend with the unpredictable and low demands of the service parts, but must also rely on human decision-making concerning a number of subjective factors. These subjective factors, which are related to the customer, the contract and the contracted product, have seldom been considered in the literature on inventory planning. Moreover, the evaluation of subjective factors often becomes non-standardized and non-coordinated among the geographically dispersed decision-makers of an organization, as was the situation with a Fortune 100 company’s case that motivated this paper. We propose a combination of a heuristic procedure along with the Analytical Hierarchy Process technique that has not been applied in the inventory-planning setting. We also demonstrate how a Web-based information system can be used to standardize the decision process, and discuss the implications of the system on the motivational case. Computational results are also provided to show the effectiveness of the heuristics.
