This work aims to explore a novel framework to analyze the planning concepts in product development projects employing techniques to reduce the lead-time of activities, such as overlapping of a pair of each. With the System Dynamics methodology, a model to evaluate the rework fraction, needed to accommodate the deviations proportional to the overlapping grade of the activities, is developed. A ...

This paper presents an empirical study in an industrial context on the production of software using a framework. Frameworks are semicomplete applications, usually implemented as a hierarchy of classes. The framework is developed first, then several applications are derived from it. Frameworks are a reuse technique that supports the engineering of product lines. In the study, we compare quality ...

Photolithography is the most complex of the operations involved in the fabrication of a wafer, and it requires the greatest precision. Photolithography is used to create multiple layers of circuit patterns on a chip. Traditionally, wafer fab operations, and in particular, those performed in the photolithography processing area, have always presented challenging scheduling and control problems. ...

The inherent iterative nature of product design and development poses significant challenge to reduce the product design and development time (PD). In order to shorten the time to market, organizations have adopted concurrent development where multiple specialized tasks and design activities are carried out in parallel. Iterative nature of work coupled with the overlap of activities can result ...

The proposed study considers both product deterioration and production process deterioration in a traditional Economical Production Quantity model. In this model, backlog and rework process are also taken into consideration while the production process is assumed to be imperfect. Unserviceable products will be manufactured as a result. Unserviceable products are kept in storage until the end of...

This document talks about the usage of Simulation Data Exchange (SDX) (Moorthy 1999) in order to enable a consistent digital model of automotive factories. The scope of the digital model is to plan and analyze the factory by using different software packages. Thus the model doesn’t exist in only one application. Therefore the consistency in terms of geometry and process data needs to be guarant...
