I think that you can apply a survey to a group of expert to identify the empirical parameters in management science. Later, you can make a model o evaluate the management science according the parameters defined previously by the experts.

I would suggest you chain on references involving Profs. Aleda V. Roth at Clemson Univ. and Art Hill and Roger Schroeder (emeritus) at the Univ. of Minnesota. These individuals have been bulwarks of empirical research in operations management and management science for decades. 

In fact my query was about a journal article published in Management Science that had dealt with models using empirical data. I want to know if the editorial board at Management Science has guidelines or special requirements about the sample size, methodology etc. of a survey or field study.

Dear Dr. Brusset

Your problem "the editorial board at Management Science has guidelines or special requirements about the sample size, methodology etc. of a survey or field study."

I suggest you can read the article "Why Top Journals Accept Your Paper, MIS Quarterly Vol. 33 No. 3 pp. iii-x/September 2009." This paper have been pointed out what criterial or requirements should have in your paper, then top journal such as Management Science maybe accept to publish.

Good luck to you
