    1. Introduction

    Imaras is an online multi-attribute reverse auction system powered by Invite. In an Imaras auction, there is one buyer (or seller) and several sellers (or buyers). The sellers are bidding against each other to get the buyer to accept their offer. Each auction is comprised of several rounds, lasting a pre-set amount of time. Sellers submit offers only to the buyer, but there is no other exchange between them. For more information, please refer to Imaras bidding process and to multiattribute auctions and bidding for a detailed discussion.

    In brief, the auction involves a preparation phase during which the buyer (if it is a human agent) and the sellers read the case description, beginning with Public information that is available to everyone and then the Private information that only you will see. The buyer and sellers then proceed to a bid submission phase during which the sellers bid against each other in order to win the auction. More information is available from the system itself.

    All auctions have a deadline. Remember to complete your auction by the deadline. After the deadline, you can no longer bid and may only participate in post-auction activities (e.g. review the case and auction transcript, give your comments and feedback).

    Also, please note that in addition to the auction, online questionnaires may be added during this process for the purpose of improving the system as well as research purposes, In particular, the pre-questionnaire(s) may be given before the actual auction phase (i.e. bid submission), and the post-questionnaire(s) will be included in the post-auction activities. Please fill out the questionnaires carefully. This is important for us to provide better systems and services for your auctions.
