Semiconductor manufacturing facilities are very complex. To obtain a fundamental understanding of the effects of dispatch and lot release rules on the factory performance based on a full factory model is difficult. In this paper, we therefore present a simple factory model that is intended to show essentially the same behavior as the complete factory. The model consists of the bottleneck workce...

In this paper, based on Key Performance Indicator (KPI) and Key Activity Indicator (KAI) as the fundamental data for calculating defined factory performance function, evaluation system of factory performance is discussed by following four phases. 1) Designing framework for evaluation system of factory performance, 2) Constructing structure of KPI/KAI database, 3) Formulating evaluation of facto...

Acanthamoeba are infected by a remarkable diversity of large dsDNA viruses, the infectious cycles of which have been characterized using genomics, transcriptomics and electron microscopy. Given their gene content and the persistence of the host nucleus throughout their infectious cycle, the Marseilleviridae were initially assumed to fully replicate in the cytoplasm. Unexpectedly, we find that t...

Anti-patterns, one of the reasons for software design problems, can be solved by applying proper design patterns. If anti-patterns are discovered in the design phase, this should lead an early pattern recommendation by using relationships between antiand design patterns. This paper presents an idea called Antipattern based Design Pattern Recommender (ADPR), that uses design diagrams i.e. class ...

The abstract factory design pattern is a well known and widely applied design in the construction of object-oriented software. An amendment to the abstract factory is presented based on the \envelope/letter" idiom. This results in factory products being instantiated in application code in a manner apparently independent of the factory pattern. Application code can thus forget about the factory,...

Nowadays, knowledge has a major role in factory efficiency. The integration of knowledge and decision support systems in the whole factory process appears as a key for the factory of the future. The basic concept of our research work is facilitating interactions between the human being in critical working situations and information set in the factory. Our proposition is to develop a “digital fa...

Wastewater is the remainder of an activity released in liquid form. product feared to have negative influence on environmental balance; therefore, it necessary measure quality standards wastewater as a reference disposal and treatment. Bioremediation environmentally friendly technology utilizing microorganisms agents process cleaning or restoring conditions. The use microorganism services can r...

The impact and cost of synthetic fertilizers as well as their associated risks on the environmental safety was becoming unaffordable. To alleviate these problems, integrating this synthetic fertilizers with easily available and an environment friendly compound like bio-char is of very high significance towards meeting our goal of increasing agricultural production and ensuring food security. Th...

This paper proposes a systematic method of creation and application of a virtual factory. Basic definition of a of virtual factory is first given , followed by its foundation principles and architectural overview, and then a systematic method based on object technologies is proposed to create the virtual factory. Specially, for a real manufacturing environment, a corresponding virtual factory c...

Ad hoc communication applications, such as computer-facilitated collaboration, have become possible with the rapid advancements in portable computing and ad hoc wireless networking. Ad hoc communication solutions require a balance between private communications and access to corporate networked services in order to succeed. In this paper, we discuss and offer some approaches in integrating ad h...
