Time horizons in budgeting

Towards Periodic Budgeting in Real-Time Calculus

In this report, we extend the real-time calculus model with a periodic budgeting mechanism known as deferrable service. Based on this extended model, we prove a schedulability theorem for a real-time task under a deferrable server. Using this theorem, we show by means of an example that existing schedulability analysis for real-time tasks under a deferrable server is pessimistic rather than exact.

Extended Time Horizons

Input–output analysts are often confronted with requests for impacts assessments for economic shocks that stretch uncomfortably the assumptions of standard input–output modeling. This paper presents an approach to confronting a subset of these challenges straightforwardly in a way that ameliorates some of the more restrictive input– output assumptions, maintains the inter–industry detail of the...

The Investigation of Main Determinants of Real Time Performance based Budgeting in Iran

The main aim of this paper is to investigate the indicators affecting the establishment of a real time performance-based budgeting system in Iran. Given that the results of this study can be used in the development of budget rules and regulations based on public sector performance, it is practical research. To achieve this purpose, a questionnaire consisting of 28 questions was designed by rese...

Towards Budgeting in Real-Time Calculus: Deferrable Servers

Budgeting of resources is an often used solution for guaranteeing performance of lower priority tasks. In this paper, we take a formal approach to the modeling of a deferrable server budgeting strategy, using real-time calculus. We prove a scheduling theorem for deferrable servers, and as a corollary show that an earlier claim of Davis and Burns, that periodic servers dominate deferrable server...
