Workflow systems are often associated with Business Process Re-engineering (BPR). This paper argues that the functional access control requirements in workflow systems are rooted in the scope of a BPR project. A framework for access control in Workflow Systems is developed. The framework suggests that existing Role-based Access Control (RBAC) mechanisms can be used as a foundation in workflow s...

Proportional service differentiation models are simple and effective approaches to service differentiation in Internet. Schedulers for delay differentiation are important elements of these models. We describe a new scheduler for proportional delay differentiation called BPR+: Optimized BacklogProportional Rate scheduler. BPR considers waiting times of packets that are backlogged in queues in or...

Business Process Reengineering (BPR) is an important aspect of Business Process Management. The concept of BPR has been widely discussed in the past decade; however, it remains undetermined how prevalent the applications of Davenport, Hammer and Champy’s ideas are, especially with respect to their relevancy for actual business practice. This paper analyses which ideas of BPR actually have been ...

Bayesian Personalized Ranking (BPR) is a representative pairwise learningmethod for optimizing recommendationmodels. It is widely known that the performance of BPR depends largely on the quality of the negative sampler. In this short paper, we make two contributions with respect to BPR. First, we find that sampling negative items from the whole space is unnecessary and may even degrade the perf...

BACKGROUND People with Severe Mental Illness (SMI) frequently experience problems with regard to societal participation (i.e. work, education and daily activities outside the home), and require professional support in this area. The Boston University approach to Psychiatric Rehabilitation (BPR) is a comprehensive methodology that can offer this type of support. To date, several Randomised Contr...

The possible applicability of business process reengineering (BPR) to organisations in the public sector is explored through analysis of the central issues in BPR and the emerging experience of organisations which have recently implemented it. In particular, the paper suggests that success of reengineering may depend critically on the strategic capability of the organisation prior to undertakin...

This study was conducted with the aim to collect and review the work done so far in the field of BPR. Focus of this study was on providing a comprehensive overview of overall development of BPR concept, theories, models, approaches and outcomes, and success and failure causes. Design/Methodology/ Approach: study was based on secondary source i.e. published and available researches in the field ...

Priority setting is an important component of systematic planning in health promotion and also factors into the development of a comprehensive evaluation plan. The basic priority rating (BPR) model was introduced more than 50 years ago and includes criteria that should be considered in any priority setting approach (i.e., use of predetermined criteria, standardized comparisons, and a rubric tha...

The purpose of this paper is to model the impact of changes in the planning and control of customer orders when companies shift from batch to customised production. During the 80's and 90's many companies have improved their production structures, facilities and processes in order to reduce setup-time, stock, work-in-process etc. However, a study of case companies indicates possible improvement...
