This paper discusses how simulation was used to evaluate and characterize the scheduling issues in a semiconductor fab and the subsequent implementation of an integrated scheduling solution. The scheduling system was integrated with the fab MES and a number of other data sources including an integrated machine standards database, preventative maintenance scheduling and a Kanban stage calculatio...

Several Language Resources (LRs) for Portuguese, developed at the Center of Linguistics of the Lisbon University (CLUL), are available on-line at CLUL’s webpage: www.clul.ul.pt/english/sectores/projecto_rld.html. These LRs have been extracted from or developed based on the Reference Corpus of Contemporary Portuguese (CRPC), a monitor corpus containing, at the present, more than 300 million word...

This paper presents a new approach for off-line signature verification. The proposed system is based on global, grid, ink distribution and texture features. The Boosting algorithm is applied to train and integrate multiple classifiers, and the distance-based classifier used as the base classifier corresponding to each feature set. Adaptive threshold is associated with individuality. Experimenta...

This study examines the influence of factors responsible for work stress among the employees in the public sector industries in Kerala, India. The sample size of the subjects selected for the study consists of 75 Engineers, 110 Supervisors and 675 Workers in the selected manufacturing industries in kerala, India. Seven factors were identified with the existing literatures, and in consultation w...

A simulation-based real-time scheduling mechanism for dynamic discrete manufacturing is presented in this paper. Modified mean flow time performance for different scheduling approaches is compared through off-line simulation experiments, under dynamic manufacturing environments that are subjects to disturbances such as machine breakdowns. These experimental results are used as reference indices...

The increased turbulence of corporate environments for production enterprises is characterized by shortened product lifecycles and cumulative variants. Customers demand smaller delivery lotsizes with higher variance and shorter delivery times. Short lead times and the resulting need for fast reaction to dynamically changing environments play a major role in production planning and control (Wieh...

The part families with precedence constraints problem (PFP) arises in industry, when flexible manufacturing systems are designed within a group technology approach. The aim of this problem is to arrange parts into families by imposing capacity constraints, concerning both the number of parts and processing times, besides precedence constraints in the building of families. Mixed binary linear pr...

One of the critical factors affecting the electric utility and electrical manufacturing industries is the forecast of the long-term demand for electricity. Superficial forecasts based on either past time trends or very broad based factors for the entire United States do not provide sufficient confidence for long-range planning. This effort is an attempt to examine the basic factors in the U. S....
