First, the concept of the two practices are different.
The same are in the "open, fair, just" slogan, the bidding party's bidding documents for evaluation, but the concept of the two are very different. "Comprehensive bid evaluation method", is the bidder on the bidder's various requirements, divided into categories, such as qualification requirements, technical level and program requirements, delivery time or completion of the progress of the project and so on; the total bid price and payment methods and so on ...... all the Requirements, totaling 100 points. Each specific sub-item is also clearly defined how many points each accounted for. At that time, according to the provisions of the bid evaluation committee members of the bidding documents "scoring", and comprehensive sum. Finally, take the "points" the highest bidder as the winner. Therefore, this method is actually a comprehensive comparison of the bidder's requirements and the degree of response of the bidder, converted into a "percentage" of the "scoring method". Can be referred to as "scoring method".
The so-called "lowest bid evaluation method" is not a strict statement. Mr. Tang Guangqing repeatedly emphasized, said it is "evaluated the lowest price winning" approach. Note that this is not the "lowest bid"; it can be imagined that the international bidding, the bidder may be quoted in U.S. dollars; perhaps the Japanese yen or the euro, which must be converted and then compared; in the more complex international bidding for electromechanical equipment or large-scale project bidding, the bidding documents are difficult to comply with the requirements of the bidding documents, sometimes there are "omissions". Sometimes there are "omissions" or individual indicators of deviation (within the allowable range), which also needs to be discounted.
So, strictly speaking, this approach, is to meet or deviation of all the technical and economic indicators, in accordance with the provisions of the bidding documents in advance, uniformly converted into an amount. Above can be referred to as "evaluation price". Take one of the "lowest bid evaluation price" for the winner.
Second, the two methods of drawing and hiring experts are different.
"Comprehensive bid evaluation method", the extraction of experts, most of the "same type of professional". To my understanding of part of the situation, the construction project bidding evaluation, most of the experts are hired: "cost engineer", "supervision engineers" and so on comprehensive personnel.
While the "lowest bid evaluation" approach to winning the bid, employing experts, may be multi-disciplinary. For example, "CNC machine tools; machining centers" bidding, you can hire machine tool manufacturing experts, with CNC technology research experts; medical equipment (ultrasound; CT, etc.), may employ medical equipment manufacturing experts, will also employ the long-term use of the equipment in the hospital instrumentation of medical experts.... ...
Third, the bid evaluation process differs between the two practices.
"Comprehensive bid evaluation method", in addition to individual (perhaps many) rejected bids, each expert jury, each bidder's documents, are to give "scores". Finally, each bidder's score is calculated; then summarized; and then compared to the best.
The process of the "lowest bid evaluation method" generally involves: a preliminary examination (conformity check) - an in-depth qualification check - a commercial check - a technical conformity check - a technical conformity check - an in-depth qualification check - a technical conformity check - a technical conformity check - a technical conformity check - a technical conformity check. -Technical conformity check - price discounting and so on.
In the middle there may be question and answer, to be determined, the evaluation of the tender members can make an evaluation.
At the end of the process, when the "evaluation price" is calculated, the ranking of the bidders is clear, and the final winner is also clear.
