Due to the complicated circumstances in workshop, most of the conventional scheduling algorithms fail to meet the requirements of instantaneity, complexity, and dynamicity in job-shop scheduling problems. Compared with the static algorithms, dynamic scheduling algorithms can better fulfill the requirements in real situations. Considering that both flexibility and fuzzy processing time are commo...

The job of software architect is considered very crucial in the life cycle of the software development because software architecture has a pivotal role in the success and failure of the software project in terms of cost and quality. People have different personality traits, and the way they perceive, plan and execute any assigned task is influenced by it. These personality traits are characteri...

The paper exploits distributed object technology to develop an enterprise application that integrates material requirement planning (MRP) with job shop simulator. The application aims to realize an integrated system that has rapid response to changing requirements and capability to integrate heterogeneous manufacturing facilities. At first, the application accepts the customer’s order and perfo...

Acute low back injuries are described in a cohort of about 31,000 material handlers employed in all Home Depot, Inc., retail stores in California from 1990 through 1994. With over 87 million work hours, incidence density rates, rate ratios, and confidence intervals are given by age, sex, length of employment, and job-lifting requirements. Injuries are further described by lost work days, activi...

The Web contains new potential sources of quantitative data that could be used to explore different aspects of library and information science profession. In this article the extent to which online syllabi and job announcements could be valuable sources to determine how the contents of LIS academic courses match with the existing job requirements in the libraries is assessed. A content analysis...

In this paper we consider the labor constrained scheduling problem (LCSP), in which a set of jobs to be processed is subject to precedence and labor requirement constraints. Each job has a speciied processing time and a labor requirements proole, which typically varies as the job is processed. Given the amount of labor available at each period, the problem consists in determining starting times...

We present algorithms, methods, and software for a Grid resource manager, that performs resource brokering and job scheduling in production Grids. This decentralized broker selects computational resources based on actual job requirements, job characteristics, and information provided by the resources, with the aim to minimize the total time to delivery for the individual application. The total ...

How are tasks bundled into and across jobs within organizations? In this paper, I develop a model of this process of job design by drawing on a multisite qualitative study of task allocation following the installation of a DNA sequencer. The model that emerges is one of the assembly of tasks through multiple subassembly processes with multiple assemblers. Four activities produced requirements a...

The growth of e-science and grid computing has presented new opportunities to researchers working on distributed, collaborative projects, or for whom access to large computational and data-storage resources is essential. There is, however, much work to be done to improve the experience for these users, in particular by mitigating the effects that failing to consider fully the requirements of th...

Attractive work has been defined as a job position which an individual wants, where the employee experiences job stability and where employee identification and dedication are fostered. The present study is aimed at increasing knowledge about attitude changes to work during young people’s transition from school to work-life. A closed cohort, consisting of 225 pupils from graduating classes in 1...
