An improvement in the technical processes of batch preparation

AbstractKitting – meaning to supply assembly with components in presorted kits – is widely seen as beneficial for assembly quality and efficiency when there is a multitude of component variants. However, the process by which kits are prepared – the kit preparation – is labour-intensive, and kit errors are problematic at assembly processes. The use of robotics to support kit preparation has received some attention by researchers, but literature is lacking with respect to how collaborative robots – cobots – can support kit preparation activities. The purpose of this paper is to identify the potential of a cobot to support time-efficient batch preparation of kits. To address the purpose, the paper presents a mathematical model for estimation of the cycle time associated with cobot-supported kit preparation. The model is applied in a numerical example with experimental data from laboratory experiments, and cobot-supported kit preparation is compared with manual kit preparation. The findings suggest that cobot-supported kit preparation is beneficial with diverse kits and smaller components quantities per SKU (Stock Keeping Unit) and provides less variability of the outcome, when compared to manual kit preparation. The paper reveals several insights about cobot-supported kit preparation that can be valuable for both academics and practitioners. The model developed can be used by practitioners to assess the potential of cobots to support kit-batch preparation in association with assembly, spare parts, repair and maintenance, or business to business industry.

Plasma Activity

The yields from batch preparation of Factor VIII concentrates can be substantially improved by collecting the blood into heparin rather than into CPD as anticoagulant. The resultant cryoprecipitate contains 78 ± 9% of the original plasma activity if 20 mls of supernatant per litre of starting plasma are left with the cryoprecipitate to maintain heparin levels. This cryoprecipitate was further purified by solubilization at 37°C for 5 minutes using 40 cc of saline per litre of starting plasma. This preparation was adjusted to pH 6.3 and 4.5% PEG 4000. Then, after removal of the precipitate by centrifugaron, the 4.5% PEG supernatant is adjusted to pH 6.0 and 11% PEG. The 11% PEG precipitate obtained after centrifugation is resolubilized in 1/100th the original plasma volume with buffer (0.1 M glycine, 20 mM citrate, 0.15 H saline) containing 1 unit of heparin per ml. Experiments using plasma pools containing 1-15 donor units gave yields ranging from 390-490 plasma Factor VIII equivalents per litre of the starting plasma. The final product retains an average of 90% of the initial Factor VIII activity after 24 hours at 22°C. It is believed that the present method could substantially reduce the cost of producing Factor VIII concentrates.
