Facing new challenges and more uncertainty, manufacturers see the need for flexible solutions and the need to strive to achieve flexibility. However, flexibility is still not well understood and no unambiguous understanding of flexibility exists. The paper first summarizes the state of the field of flexibility, exploring different definitions and understandings of the flexibility concept from t...

European Journal of Information Systems (2007) 16, 525–526. doi:10.1057/palgrave.ejis.3000710 In this issue of the European Journal of Information Systems, we have a special section on Locating Packaged Software in Information Systems Research guest edited by Sawyer and Light as well as four general papers. Coincidentally one of the four general papers is also authored by Ben Light, introducing...

Arguably, the natural gas transmission pipeline infrastructure in Iran represents one of the largest and most complex mechanical systems in the world. The optimization of large gas trunk lines known as IGAT results in reduced fuel consumption or higher capability and improves pipeline operation. In the current study, a single-objective optimization was conducted for Khormoj compressor station o...

Accurate estimation of motion from time-varying imagery has been a popular problem in vision studies, This information can be used in segmentation, 3D motion and shape recovery, target tracking, and other problems in scene analysis and interpretation. We have presented a dynamic image model for estimating image motion from image sequences, and have shown how the solution can be obtained from a ...

risk assessment and management of petrochemical feed and product transportation pipelines is very important to preventing probable accidents. so, 60 pipelines evaluated by chemical exposure index and chlorine pipeline due to high hazard distances selected for relative risk analysis. the chlorine pipeline with 3468 meter length divided to 100 meter sections, and third party damage index (tpdi), ...

A highly enantioselective cyanohydrin synthesis with aromatic aldehydes using chiral lithium binaphtholate aqua or alcohol complexes has been developed and is a simple and inexpensive catalyst suitable for process chemistry to give gram-scale cyanohydrins successfully. Dramatic improvements in enantiomeric excess have been realized along with an interesting changeover in absolute stereochemistr...

By estimating a staggered price model over the period 1980q1-2010q2, this paper documents that, after the euro changeover, Italian retailers have increased the number of price adjustments, which has translated into a higher inflation rate, with a detrimental effect on the competitiveness of the Italian economy.

Until now, it is not known how the motors of E. coli reverse the direction of rotation, mostly simultaneously. If the C-ring is bistable and if the number of bound CheY-P depends on the direction of rotation, there is a strong variation in the concentration of CheY-P in the cytoplasm. Then, the synchronous changeover can be explained without further additional assumptions.

This paper addresses the problem of aperiodic scheduling of manufacturing systems under Hard Real-Time constraints. It adopts the extended version of the Total Bandwidth Server Algorithm and extends it to include the novel feature of including changeover time costs. Index Terms – Real-time Systems scheduling, Production Planning and Control.
