The idea of exploring contract management in this way seems quite promising, but you will need to think about issues of scale, and be sure that your paper has sufficient reference to the role of EM (as opposed to the issues for grid contract management). This might be achieved either by thinking of your model-building as addressing feasibility issues or an educational objective. I think that it would be good to include some discussion of general issues to do with decision-support using EM principles, for which the most appropriate background reading is in papers authored by Steve Russ, Suwanna Rasmequan and Chris Roe or myself. A particular theme in these papers on decision-support is linking manual and automated perspectives on decision-making (restaurantRoe2000 is probably the most cited example). I appreciate that there is an interesting problem here in that the contract manager is an automatic agent whose decision-making performance is possibly not easily related to that of a human agent, but this could be an interesting theme in itself. You will probably find that this suggests some other angles on the contract topic, which at present you describe from a rather limited perspective.

Not sure how useful you have found / will find your chosen references - though the AI theme may be appropriate, the direct relevance of these papers isn't entirely clear, and decision-support is likely to prove closer to your theme. Good to bear in mind the possibility of giving a prominent role to an LSD analysis, since this is a way to make the link to EM more conspicuous, and also links well with the 'agent-oriented' focus of your thinking. Since there are a number of modelling projects relating to the Grid in one way or another, you might also like to consider whether you could extend your model (if only in principle) to exploit features modelled by another student. This would be a good topic to discuss in a paper, provided that you take care to avoid any risk of plagiarism.

Good to include reference to models such as the restaurant manager model. The link for the Aydt reference is missing in my version of your submission.

'geographically disperse' -> geographically dispersed
Clumsy sentence: 'A contract management module can be viewed as a supervising agent ... user will be notified.' - good to re-read your sentences carefully to pick up awkward syntax.
