Two summer outbreaks of humidifier fever (HF) are described in a microprocessor factory (factory A) and a printing factory (factory B). The air in each factory was humidified intermittently and controlled by present humidistats operating to maintain a relative humidity of 45% by an air handler incorporating a spray humidifier in factory A and two ceiling mounted spray humidifiers in factory B. ...

Due to short product life cycles, increasing variety of products and short cycles of leap innovations manufacturing companies have to increase the flexibility of factory structures. Flexibility of factory structures is based on defined factory planning processes in which product, process and resource data of various partial domains have to be considered. Thus factory planning processes can be c...

Abstract— In order to determine factory capacity or necessary time to reach a desired quota, the manager of a multi-product batch manufacturing system must know the best method of scheduling for the factory. To determine the optimal scheduling, we first create a model of the factory. This model is used to simulate the factory. Using this simulation and an integer programming formulation, we det...

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...
