A Review of SLA Constraints and Scheduling Methods and Behaviour
ثبت نشده
چکیده
A cloud system environment is considered as the framework to provide resource and service distribution to the users. These different environment forms are accessed by different users under the service specification. The constraints at different levels are negotiated between the providers and the users. The paper has defined the different cloud services relative to the SLA behavior. The paper also identified the benefits of scheduling method for resource utilization and effective service distribution in cloud environment. The categorization of available scheduling methods is also provided along with feature exploration.

A Nurse Scheduling Model under Real Life Constraints
Background and Objectives: In this paper, a real life nurse scheduling model is described based on the conditions in Iranian hospitals such as monthly shift rotation, consecutive morning and evening shifts and consecutive evening and night shift. Methods: The developed model considers both hospital constraints and nurses’ preferences. Hospital constraints include assigning adequate qualifie...
متن کاملSINGLE MACHINE DUE DATE ASSIGNMENT SCHEDULING PROBLEM WITH PRECEDENCE CONSTRAINTS AND CONTROLLABLE PROCESSING TIMES IN FUZZY ENVIRONMENT
In this paper, a due date assignment scheduling problem with precedence constraints and controllable processing times in uncertain environment is investigated, in which the basic processing time of each job is assumed to be the symmetric trapezoidal fuzzy number, and the linear resource consumption function is used.The objective is to minimize the crisp possibilistic mean (or expected) value of...
متن کاملSingle Machine Scheduling Problem with Precedence Constraints and Deteriorating Jobs
This paper considers the single machine scheduling problem with precedence constraints and deteriorating jobs. A mathematical model based on binary integer programming (BIP) is developed. By these precedence constraints, jobs can not start before completion of its all predecessors. The represented model is in two steps, in step one the earliest starting time of each job is computed, then the re...
متن کاملOperating Room Scheduling in Teaching Hospitals: A Novel Stochastic Optimization Model
Background and Objectives: Operating room (OR) scheduling is key to optimal operating room productivity. The significant uncertainty associated with surgery duration renders scheduling of surgical operation a challenging task. This paper proposes a novel computational stochastic model to optimize scheduling of surgeries with uncertain durations. The model considers various surgical operation co...
متن کاملA novel mathematical model for a hybrid flow shop scheduling problem under buffer and resource limitations-A case study
Scheduling problems play a big role in manufacturing and planning the production for increasing the production efficiency and assigning the resources to operations. Furthermore, in many manufacturing systems there is a physical space between stages that called intermediate buffers. In this study, a model is proposed for minimizing the makespan of a hybrid flow shop scheduling problem with inter...
