(1) bid schedule module

Bid and purchase type comprises goods, engineering and service, for goods buying intensive enterprise, needs to build bid schedule module, and this module comprises that bid plan is set up, goods and materials gather, generates the functions such as project for bidding.First by department of subordinate, generate bid plan, the buying goods and materials that propose for multi-service group gather rear submission higher level department to be examined.Higher level department, after the bid plan of receiving department of subordinate, examines, and Bing Yu this department calculated buying goods and materials that self call for bid gather, continue to report, the like.Finally, enterprise procurement plan reports purchasing department, and purchasing department gathers goods and materials according to all bid and purchase plans, and generates project for bidding accordingly, carries out bidding work.

And for engineering or services procurement intensive enterprise, often do not need so complicated goods and materials plan aggregation process but directly specify project for bidding, concrete purchase engineering or service are set in project essential information, therefore do not need the schedule module that calls for bid.Therefore, this module, as additional function, is configured according to customer demand.

(2) material master data module

Equally, for goods buying intensive enterprise, the goods and materials of each buying have very large repeatability, if each counterpoise copy back enters material information, waste time and energy.Therefore need to build material master data module, the material information of enterprise procurement is carried out to unified maintenance and management, each buying only need be chosen correlative and fill in a small amount of information (as purchase quantity etc.) from this module.And for engineering or services procurement intensive enterprise, without subfunction.Therefore, this module also will be configured according to customer demand.

2. functions of modules item configurability

In each functional module partial function details, can be configured according to customer demand, specific as follows:

(1) project for bidding layer of structure

According to the actual investigation of many companies, finding,, when project being carried out to level division, there is two kinds of double-layer structure and three-deckers in project for bidding project initiation phase, and wherein double-layer structure comprises project, bag, and three-decker comprises project, mark, bag.Owing to drawing with different levels difference, subsequent project management and bid flow process are all had to impact, therefore, this part is as configuration feature.When client needs double-layer structure, be configured rear project project initiation phase and subsequent process and all with double-layer structure, carry out functional configuration, needing three-decker is in like manner can obtain.

(2) node type branch

When guaranteeing trunk bid flow process, at fine granularity Nodes, there is type selecting, these select also will have influence on bid fine granularity flow process.Comprise and adopt open bidding still to invite, whether prequalification file needs to buy, and whether bidding document needs to buy, and whether the assessment of bids Committee of Experts divides into groups to set up etc., and these, reasonably configure according to customer requirement all by Configuration.

3. the setting in storehouse

In bid flow process, all there is larger difference in each company to the demand of various masterplates, tender Evaluation Method, therefore, need to set up template base, tender Evaluation Method storehouse, and for no customer demand, distribute corresponding masterplate and tender Evaluation Method.

(1) template base

In bid flow process, need to write heap file, for standardized management, Mei Jia enterprise can set corresponding masterplate for certain class file, and the realization of template base is exactly for convenience of enterprise, to select to be applicable to the document template of oneself requirement.

By file type, in template base, there is bulletin masterplate, supplier's qualification preliminary hearing masterplate, expert's qualification examination masterplate, note masterplate, assessment of bids preliminary assessment masterplate, the auspicious version of discussing and select model workers of the assessment of bids.System is all set multiple format to the template of each type, and client selects according to self-demand the template type needing on the one hand, on the other hand, can select the sample format existing in every class template, and system maintenance personnel will be configured according to customer demand.

(2) assessment of bids index storehouse

When carrying out the assessment of bids, need to set up certain assessment of bids index, expert gives a mark to supplier for index, obtains supplier evaluation basis score data.

System is set up many cover assessment of bids indexs, and client selects according to self-demand.In addition, can open self defined interface, client can, on the basis of existing index set, increase assessment of bids index.

(3) tender Evaluation Method storehouse

Assessment of bids main method comprises minimum Bid Evaluation Price method, comprehensive scoring method, cost performance method, and system realizes the multiple tender Evaluation Method that comprises above-mentioned three kinds of methods, for customer selecting.

In addition, for each tender Evaluation Method, the weight setting of assessment of bids index is crucial, and system arranges multiple weight method to set up, and concrete grammar and implementation process are as follows:

1) Delphi method

Delphi method, its feature is to concentrate expert's experience and suggestion, determines each index weights, and constantly in feedback and modification, is obtaining satisfied result.Basic step is as follows:

1. select expert.In anthology professional domain, existing practical work experience has again the expert 10-30 people left and right of darker theoretical preparation.The rule of the n of a weight undetermined index and interrelated data and definite weight is issued to selected every expert, please they provide independently the weighted value of each index.

2. regain result, and calculate average and the standard deviation of each index weights.

3. the result of calculating and updates are returned to every expert, require all experts to redefine weight on new basis.

4. repeat the above-mentioned second and the 3rd step, until the deviation of each index weights and its average is no more than standard given in advance, namely each expertise reaches unanimity substantially, usings the average of each index weights now as the weight of this index.

2) VC Method

The coefficient of variation is the statistic of measurement data difference conventional in statistics, and the method is come it to compose power in all degree of variation sizes that are evaluated observed reading on object according to each index.The ultimate principle of VC Method is that the index that degree of variation is larger is just larger on the impact of evaluating, and weight size has embodied the size of index resolution characteristic.For avoiding dimension the brought impacts different from the order of magnitude of index, the numerical value after the method is directly used VC Method to process is as the weight of each index.

Suppose to have m item Evaluation of Investment-Benefit index, have n area power grid evaluation object, X is raw data matrix, wherein x _ijbe the numerical value of j index of i object.

1. calculate the standard deviation of each index, reflect the absolute degree of variation of each index. s in formula _jthe standard deviation that represents j index.

2. calculate the coefficient of variation of each index, reflect the relative variability degree of each index.

3. the coefficient of variation of each index is normalized, obtains the weight of each index.

$w_j=V_j/{\mathrm{\Σ}}_{j=1}^m{V}_j$

3) entropy power method

In information theory, entropy is measuring of the unordered degree of system, the effective information can metric data providing.Entropy power method is exactly the method that the size that is transferred to decision maker's quantity of information according to each index is determined index weights.The difference of a certain index is larger, and entropy is less, this index comprise and the information transmitted more, respective weights is larger.According to information-theoretical definition, the quantity of information I of i the signal transmitting in an information channel _i=-lnp _i, p _iit is the probability that this signal occurs.Therefore,, if there be n signal, the probability of its appearance is respectively p ₁, p ₂..., p _n, the average information of this n signal, entropy is

Entropy power method is composed power and is divided into following step:

1. hypothesis is evaluated n area power grid sample by m Evaluation of Investment-Benefit index, x _ijbe sample i (i≤n) with respect to the predetermined value of attribute j (j≤m), form original index data matrix

X＝(x _ij) _n×m。

2. (2) get the optimal value of each evaluation index if j direct index wherein, be the bigger the better; If j inverse indicators, the smaller the better.

3. (3) define x _ijfor degree of approach D _ij,

obtain matrix D=(D _ij) _{n * m}.

4. to D _ijbe normalized:

$d_{\mathrm{ij}}=D_{\mathrm{ij}}/{\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{D}_{\mathrm{ij}}$

Make 0≤d _ij≤ 1, obtain matrix d=(d _ij) _{m * n}.

5. calculate the conditional entropy of evaluation index j:

$E_j=-{\mathrm{\Σ}}_{i=1}^n\frac{d_{\mathrm{ij}}}{d_j}\ln \frac{d_{\mathrm{ij}}}{d_j},$ Wherein $d_j={\mathrm{\Σ}}_{i=1}^n{d}_{\mathrm{ij}}$

6. use E _maxto E _jbe normalized, obtain representing the entropy of the importance of evaluation index j:

$e\left(d_j\right)=-\frac{1}{\ln n}{E}_j=-\frac{1}{\ln n}{\mathrm{\Σ}}_{i=1}^n\frac{d_{\mathrm{ij}}}{d_j}\ln \frac{d_{\mathrm{ij}}}{d_j}$

7. by e (d _j) determine the evaluation weights λ of evaluation index j _j

${\mathrm{\λ}}_j=\frac{1}{n-E_g}[1-e\left(d_j\right)]$

Wherein, and λ _jmeet: 0≤λ _j≤ 1,

4) multiplication synthetic method

Multiplication synthetic method is by VC Method, entropy weight coefficient, the multiple weight combined sequence of Delphi method, is about to the multiplied by weight of a certain index that multiple tax power method draws, is then normalized, and obtains combining weights.Suppose to have m index, the weight w that q kind method is tried to achieve, combining weights is:

${\mathrm{\θ}}_j={\∏}_{k=1}^q{w}_j\left(k\right)/{\mathrm{\Σ}}_{j=1}^m{\∏}_{k=1}^q{w}_j\left(k\right),j=\mathrm{1,2},...m,k=\mathrm{1,2},...q$

Wherein, θ _jcombining weights for index.

5) adding combination method

If p _j, q _jthe x generating based on subjective enabling legislation and objective weighted model respectively _iweight coefficient, claim x _j=k ₁p _j+ k ₂q _j, j=1,2 ..., m

To there is the weight coefficient that simultaneously embodies subjective and objective information integration characteristic.K in formula ₁, k ₂undetermined constant (k ₁> 0, k ₂> 0, and k ₁+ k ₂=1).

Obviously, the key issue of adding combination method is undetermined coefficient k ₁, k ₂determine.Provide below by mathematical model and generate k ₁, k ₂method.

At this moment, be evaluated object s _icomprehensive evaluation value be

$y_i={\mathrm{\Σ}}_{j=1}^m{w}_j{x}_{\mathrm{ij}}={\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m(k_1{p}_j+k_2{q}_j)x_{\mathrm{ij}}$

Value is maximum.

Existence satisfies condition k ₁> 0, k ₂> 0 time, application Lagrange conditional extremum principle, can obtain

$k_1={\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{p}_j{x}_{\mathrm{ij}}/\sqrt{{\left({\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{p}_j{x}_{\mathrm{ij}}\right)}^2+{\left({\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{q}_j{x}_{\mathrm{ij}}\right)}^2}$

$k_2={\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{q}_j{x}_{\mathrm{ij}}/\sqrt{{\left({\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{p}_j{x}_{\mathrm{ij}}\right)}^2+{\left({\mathrm{\Σ}}_{i=1}^n{\mathrm{\Σ}}_{j=1}^m{q}_j{x}_{\mathrm{ij}}\right)}^2}$

This is also to embody the tax power method that is evaluated a kind of subjective and objective information comprehensive integration of (integral body) maximum difference between object.Certain k ₁, k ₂also can be determined by embodiment of evaluation person's preference information.

Especially, when getting k ₁=k ₂time, also can determine w with formula below _j:

$w_j=(p_j+q_j)/{\mathrm{\Σ}}_{j=1}^m(p_j+q_j),j=\mathrm{1,2},...,m$

Certainly, if " smoothly " produce " difference " of (to being respectively evaluated object) because of objective and subjective synthetic approach, also can be at the k that satisfies condition ₁+ k ₂=1, k ₁> 0,, k ₂> 0 time, determines k ₁, k ₂, make

${\mathrm{\Σ}}_{i=1}^m{y}_i^2={\mathrm{\Σ}}_{i=1}^n{\left({\mathrm{\Σ}}_{j=1}^m(k_1{p}_j+k_2{q}_j)x_{\mathrm{ij}}\right)}^2$

Value is minimum.

6) self-defined weights

Allow client according to self-demand, select the weights of self-defined each evaluation index.

Therefore, client can be by selecting evaluation indice, index weights method to set up, tender Evaluation Method to specify a set of Evaluating Bidding Model that meets oneself requirement, and more reasonably Dui Ge supplier evaluates.Native system will configure flexibly according to customer selecting.

4. authority resource management
