This paper addresses a new mixed integer nonlinear and linear mathematical programming economic lot sizing and scheduling problem in distributed permutation flow shop problem with number of identical factories and machines. Different products must be distributed between the factories and then assignment of products to factories and sequencing of the products assigned to each factory has to be d...

The productivity of bioengineered cell factories is limited by inefficiencies in nutrient delivery and waste and product removal. Current solution approaches explore changes in the physical configurations of the bioreactors. This work investigates the possibilities of exploiting self-organizing vascular networks to support producer cells within the factory. A computational model simulates de no...

Some properties of gas mixtures, composed predominately of helium and lesser amounts of CO2 and isobutane, were measured in a prototype drift chamber. The studies are motivated by the desire to reduce the multiple scattering inside the drift chamber at future high-luminosity, low-energy facilities such as 4 factories, T/charm factories, and B factories. The low atomic number of helium greatly r...

The purpose of a cross-sectional study was to investigate factors influencing the quality of life among Thai workers in textile dyeing factories. Samples included 205 Thai workers from five textile dyeing factories located in the suburban area of Bangkok in Thailand. Data were collected with a self-administered questionnaire. Scales of the questionnaire had reliability coefficients ranging from...

In this paper we consider a production enterprise that has several factories. This enterprise manufactures several diierent types of products on a produce to order basis. The level of operational control available within each factory with respect to scheduling is limited. Hence, it is of interest to nd the appropriate allocation of the diierent types of products to the diierent factories. In a ...

LEP has proved to be one of the most flexible ee colliders built to date. It has operated at various energies, in several modes, with everincreasing demands for luminosity in clean and precisely known beam conditions. Together with some unique features, LEP therefore has much in common with future ee factories. Beam-dynamical phenomena have been among the crucial determinants of LEP’s performan...

As a result of the Great East Japan Earthquake in March 2011, electric power supply in Japan faced a critical situation; in particular, factories that consume a large amount of electric power were seriously affected. Meanwhile, in China and other emerging countries, where the economic growth rate is high and automation of manufacturing factories is progressing, further energy saving is a key is...

Preliminary studies on crude cancer incidences among workers from 89 factories in Shanghai revealed excessive risk of cancer for workers in certain workshops of rubber tire factories. Chronic in situ animal exposures showed that compounding and Banbury mills for mastication and mixing were origins of carcinogenic contaminants. Various chronic experiments indicated the carcinogenicity of PBNA in...

Neither Dark Matter nor scalar particles in the Higgs sector are ruled out at energies accessible to bottom and charm factories. In Dark Matter searches, the error on the mass of Dark Matter is ∼ 4 GeV in the best LHC studies. For light Dark Matter this could represent a 100% (or more) error. In Higgs searches, the presence of a light singlet Higgs can make the LHC Higgs search difficult, if no...

INTRODUCTION: THE INDUSTRY AND ITS PROBLEMS AT THE BEGINNING of the nineteenth century 128 mines and metallurgical factories were in operation in the Ural Mountains. Many had been destroyed in Pugachev's rebellion (1773) but they had been quickly rebuilt. As a result of periodic changes in government policy in the previous century, when private enterprise was alternately encouraged and discoura...
