The principal function of a control chart is to help management distinguish different sources of variation in a process. Control charts are widely used as a graphical tool to monitor a process in order to improve the quality of the product. Chen and Hsieh (2007) have designed a T2 control chart using a Variable Sampling Size and Control limits (V SSC) scheme. They have shown that using the V SSC...

Optimization is a classical notion in control theory. It is often required in engineering practice. As a case study, this paper represents an initial contribution to the formalization of the concept of optimization of hybrid systems and also explores its analytic and synthetic techniques. The illustrative case is a fluid double-tank example and the logical notation employed in the formalization...

This paper proposes an extended earned value management (EEVM) as an integrated comprehensive project progress measurement technique. The method considers all of project key success factors, simultaneously. That is the method guaranties the realistic weights achievement to implement project control and scheduling. The weights are employed to publish a correct and comprehensive progress reports ...

Knowledge engineering upholds a longstanding tradition that emphasises methodological issues associated with the acquisition and representation of knowledge in some (formal) language. This focus on methodology implies an ex ante approach: “think before you act”. The rapid increase of linked data poses new challenges for knowledge engineering, and the Semantic Web project as a whole. Although th...

In this paper the most diicult step of a method is presented by which requirements in the duration calculus (DC) can be transformed into occam programs such that the implementation is correct by construction. Several rules for correct transformations from DC towards an important intermediate stage, the speciication language SL time , will be shown. In particular we shall explain the interplay b...

BACKGROUND The Union-Bloomberg Initiative tobacco control projects were implemented in Himachal Pradesh (a hilly state in North India) from 2007 to 2014. The project focused on the establishment of an administrative framework; increasing the capacity of stakeholders; enforcement of legislation; coalition and networking with multiple stakeholders; awareness generation with focus on earned media ...

We ask how to regulate pecuniary private benefit consumption. These benefits can compensate controlling shareholders for monitoring managers and investing effort in implementing projects. Controlling shareholders may consume excessive benefits, however. We argue (a) ex post judicial review of controlled transactions dominates ex ante restrictions on the controlled structures: the latter elimina...

Most commonly used control charts for monitoring quality characteristics of the processes were developed under the assumption that the observations are randomly sampled from a normal population. It is well known that these control charts have more false alarms than usual when processes are positively autocorrelated. One remedy is to adjust the control limits such that the modified control chart...

The development of the Earned Schedule (ES) method by Lipke in 2003 has been shown to be an important extension to the Earned Value Management (EVM) method, increasing the utility of EVM data for project schedule analysis, control and oversight. As ES provides a reliable time-based indicator of Schedule Performance, the objective of this paper is to investigate whether the SPI(t) exhibited simi...
