Procedures are pervasive in spacecraft operations and are used to control every aspect of human spaceflight. Both ground controllers and crew members use procedures on a daily basis. Current procedure operations are document-focused with little computer support. This paper describes an information-focused procedure representation and the development of procedure assistance tools that allow for ...

The waste water treatment plants are very unstable and the waters to be treated are ill defined. The command of those processes needs to be done with advanced methods of control and supervision. They have to take into account the bad knowledge of the processes. The most important situations that imply problems for the plant are listed. Parameters for comparison between crisis and normal situati...

This paper presents an application of Functional Resonance Accident Models (FRAM) for the safety analysis of complex socio-technological systems, i.e. systems which include not only technological, but also human and organizational components. The supervision of certain industrial domains provides a good example of such systems, because although more and more actions for piloting installations a...

To explore the optimal mechanism of emergency supply chain collaboration when an epidemic crisis occurs, we construct a tripartite evolutionary game model among government, retailer, and supplier to interaction primary strategies impact critical parameters on evolution stability system. We conduct simulation analysis based actual situation China’s development. The research results show that in ...

of the perpetrators were friends or relations; 17 % were (ex-)partners. The waiting time in the Charité emergency departments amounted to 58 minutes on average, the medical treatment time 55 minutes. About 80 % of the personnel evaluated the "stuprum kit" as being altogether good or very good. More than ⅓ considered the time and room conditions as being unsuitable or rather unsuitable for the s...

Process operators often have difficulties with quality supervision and control for the following reasons: (i) analytical results are infrequent and much delayed, (ii) conventional automatic control cannot sufficiently reduce quality deviations, and (iii) several set values can be candidates for correction of quality deviations. Control performance is discussed with regard to these problems, in ...

the aim of this study was to investigate the factors affecting timely repayment of agricultural loans in fars province. the necessary data was obtained from agricultural bank as well as through 163 questionnaires, filled out in fars-province. the farmers were divided in to timely repayment and defaulter groups while standard tobit model being used for the study. the dependent variable in this m...

In many tasks related to reasoning about consequences of a logical theory, it is desirable to decompose the theory into a number of components with weakly-related or independent signatures. This facilitates reasoning when the signature of a query formula belongs to only one of the components. However, an initial theory may be subject to change due to execution of actions affecting features ment...
