The software that this project has developed can work out estimate, budgetary estimate , budget, base price, quoted price, produce beautiful and neat reports automatically, the reports can be edited according to the demand, thus cost organizers are extricated from a large amount of tedious and repetitive work.

This paper gives a description of the price quoted in the bid and the cost forecast prior to construction, which is of great significance to ensuring the economic benefits of engineering projects.

The composition method for the human unit price and estimated material price in the existing quotation should be reformed. The "controlled quantity, opening price, price quoted by an enterprise itself, finally market formed price" will be realized to link to the international way at last.

Theorems 2.2 and 2.3 make some comparisons in elasticity and certainness between fuzzy price of transaction and fuzzy price quoted and fuzzy price asking.

The conceptions of standard fuzzy price, elasticity and certainness of a fuzzy price at λ -level, fuzzy price of transaction and its expectant value are discussed. Theorem 2.1 points out that the fuzzy price of transaction will be standard if the fuzzy price quoted and the fuzzy price asking are sc.

Then the discrete optimized model which takes customer's interruption loads as reserve capacities is proposed according to the order of interruption loads and interruption power price quoted by customers.

It is the goal of this paper to present some new methods to investigate the problems in trade through the fuzzy sets theory. The conceptions of standard fuzzy price, elasticity and certainness of a fuzzy price at λ -level, fuzzy price of transaction and its expectant value are discussed. Theorem 2.1 points out that the fuzzy price of transaction will be standard if the fuzzy price quoted and the fuzzy price asking are sc. Theorems 2.2 and 2.3 make some comparisons in elasticity and certainness between...

Theorems 2.2 and 2.3 make some comparisons in elasticity and certainness between fuzzy price of transaction and fuzzy price quoted and fuzzy price asking. Theorem 2.4 proves that the expectant value of a standard fuzzy price of transaction is unigue and stable.

A contractor shall select a proper project that is to be constructed on competitive bidding basis according to both subjective and objective conditions, and may list all the influencing factors for making decision on whether to accept bid invitation by simply using evaluation - based marking method. In case a decision has been made to submit a bid, a practicable price quoting strategy shall be properly worked out to be awarded a contract for a project.
