in this paper, based on the background of cost-oriented assembly line balancing problems, a novel mathematical model for scheduling and balancing the assembly line is offered that with the combination of task sequence-dependent setup time, parallel stations and resource constraint, minimizes the operational and investment costs of assembly system. due to the complexity of the problem, the equat...

Abstract: This paper explores a Mathematical model for obtaining the minimum total cost of Multi-items with Mult-objectives in a Fuzzy Environment. The paper incorporates four constraints such as warehouse space and the constraint, investment amount constraint, percentage of utilization of volume of the ware house space and the shortage level constraint by allowing shortages. The previous resea...

Systems that are more dependable and less expensive to maintain may be more expensive to purchase. If ordinary customers cannot calculate the costs of downtime, such systems may not succeed because it will be difficult to justify a higher price. Hence, we propose an easy-tocalculate estimate of downtime. As one reviewer commented, the cost estimate we propose ‘‘is simply a symbolic translation ...

Based on our previous experience we want to compare the performance between five hypervisors: XEN-PV, XENHVM,Open-VZ,KVM-FV,KVM-PV We have simulated the migration of a virtual machine by using a warning failure approach. Based on some experiments we have compared CPU Consumption, Memory Utilization, Total Migration Time and Downtime. We have also tested the hypervisor’s performance by changing ...

The purpose of the study was to examine the cost-effectiveness of managed care interventions with respect to prescriptions for chronic illness sufferers enrolled with a specific medical scheme. The illnesses included, were epilepsy, hypertension, diabetes and asthma. The managed care interventions applied were a primary discount; the use of preferred provider pharmacies, and drug utilization re...

This paper examines the relationship among disaster tolerant systems, Information Technology (IT) application operation and availability, and the executive level management visibility necessary for system operational success. The current state of disaster tolerant application systems is explored including an investigation into the reliability and survivability requirements necessary to achieve ...
