Resources tend to follow certain availability patterns, due to the maintenance cycles, work shifts, etc. Such availability patterns heavily influence the efficiency and effectiveness of enterprise process scheduling. Most existing process scheduling and resource management approaches focus on process structure and resource utilisation, yet neglect the resource availability constraints. In this ...

In this study, we aim to present a new model for the resource-constrained project scheduling problem (RCPSP) considering a working calendar for project members and determined the skill factor of any member using the efficiency concept. For this purpose, the recyclable resources are staff resources where any person with multiple skills can meet the required skills of activities in a given time. ...

Enterprise Grid enables sharing and aggregation of a set of computing or storage resources connected by enterprise network, but the availability of the resources in this environment varies widely. Thus accurate prediction of the availability of these resources can significantly improve the performance of executing compute-intensive complex scientific and business applications in enterprise Grid...

OBJECTIVE The purpose of this study was to provide new insight into common barriers to the availability and use of nutrition education (NE) resources in Head Start preschool programs based on administrator and teacher perceptions. METHODS In-depth, semistructured phone interviews (n = 63) were conducted with administrators (n = 31) and teachers (n = 32) from North Carolina-based Head Start pr...

Complex environments for ATM based telecommunication services assume high availability and reliability of the network resources as well as the services. In order to reduce the cost of building and maintaining wide area ATM networks, efficient and cost-effective resource management techniques are needed to avoid over-allocation of resources. This requires building a network having the intelligen...

Proper and realistic scheduling is an important factor of success for every project. In reality, project scheduling often involves several objectives that must be realized simultaneously, and faces numerous uncertainties that may undermine the integrity of the devised schedule. Thus, the manner of dealing with such uncertainties is of particular importance for effective planning. A realistic sc...

Optical burst switching (OBS) technology is one of the promising solutions for the next generation Internet backbones. One of the major issues in the design of optical burst-switched networks is the estimation of the availability of network resources needed for the transmission of an input traffic while ensuring the required quality of service (QoS). A few works have addressed the availability ...

BACKGROUND The school food environment is important to target as less healthful food and beverages are widely available at schools. This study examined whether the availability of specific food/beverage items was associated with a number of school environmental factors. METHODS Principals from elementary (n=369) and middle/high schools (n=118) in British Columbia (BC), Canada completed a surv...

Education is an expensive process and the quality of an education program is largely affected by resources devoted to it. Availability of qualified instructors and physical amenities such as labs are the most important resources that determine the educational quality. Based on the graduate Information Systems curriculum recommendation of Association for Computing Machinery (ACM) and Association...
