Specifically, after receiving an index creation instruction sent by a user, index creation information in the index creation instruction is obtained, an index creation page is opened first, an index is created, an index name and a parameter need to be defined, the parameter of the index includes a parameter name and a parameter value field, the index is defined as a feature of a service, a value represented by the index is a feature value, the parameter is used for calculating the feature value, the index is defined according to the received index creation information, the index name and the parameter are defined according to the received index creation information, for example, in a certain service rule, an index a represents "tax amount", the same service feature (tax amount) of different objects (enterprise X and enterprise Y) may have a plurality of different instances (for example, tax amount of about 3 months X and tax amount of about 1 year Y) but they all point to an index a ". The index is not bound with the business rules, but the parameters in the index are bound with the business rules, because no matter how long the tax amount of the enterprise X or the enterprise Y should be paid, the index A can be used for representing the tax amount, and the parameters in specific business conditions are different.
In one embodiment, the index includes parameters that are real parameters. Specifically, because the parameters in the index are bound with the actual business rules, the parameter values in the index come from real parameters configured by the rule layer.
In one embodiment, the index further comprises a reference index, wherein the reference index comprises a reference index name and a reference index parameter, and the reference index parameter comprises a reference index parameter name and a reference index parameter value range. Specifically, the value represented by one index is calculated by the same parameter, but the parameter itself can also be one index, namely the reference index is used, the representation value of the same reference index is calculated by the parameter, namely the reference index parameter is used at the moment, and the parameter also comprises a parameter name and a parameter value field, and the corresponding reference index parameter name and the reference index parameter value field in the step are used.

Specifically, each rule is composed of logic layers, and can be directly composed of one logic layer or composed of multiple logic layers through logic iteration; and each layer of logic is composed of one or several rows of sub-rules.
In one embodiment, after step S130, further includes: judging the number of logic layers of the needed iteration of the target rule, if the number of the logic layers is greater than three, creating a new target index which is used for replacing one logic layer. Specifically, each rule may iterate at most 3 layers of logic (and/or not), and if it is found that the expected required logic layer is greater than 3 layers when constructing the target rule, then a new target indicator may be selected to be created, and the value represented by this target indicator may be substituted for the value represented by one logic layer, thereby reducing the number of layers iterated.

In one embodiment, as shown in fig. 4, there is provided a method for determining reliability of a rule result, which is based on a rule configuration method in the above embodiments, including the steps of:
s310 judges whether both sides of the logical symbol of the target rule are reliable.
Specifically, since the target rule actually appears as a logical symbol and two expressions located on both sides of the logical symbol, judging whether the target rule is reliable requires specifically judging whether the expressions on both sides of the logical symbol are each reliable.
In one embodiment, step S310 is specifically: acquiring all target indexes of each of two sides of a logic symbol of a target rule; judging whether the target index contains a default value or not; if the target index contains a default value, the side of the target index containing the default value is unreliable, otherwise, the side is reliable. Specifically, the reliability is determined, which is essentially to determine whether a default value is included, and the default value is an initial value of an attribute or a parameter before being modified. If the target index takes a default value in calculation, the target index is unreliable; if the target index does not take a default value at the time of calculation, the target index is reliable. Therefore, if there is a default value, the result of the expression indicating the side on which the target index containing the default value is located is not reliable.
S320, if both sides of the logical symbol of the target rule are reliable, the target rule is reliable.
Specifically, if the left and right expressions of the target rule are reliable, it is indicated that the default value does not exist, and it is indicated that the rule is reliable.
S330, if both sides of the logical symbol of the target rule are unreliable, the target rule is unreliable.
Specifically, if neither the left nor right expressions of the target rule are reliable, indicating that default values exist, the rule is unreliable.
If the logical symbol of the target rule is not reliable and only one side is unreliable in S340, it is determined whether the result of the unreliable side affects the result of the target rule.
Specifically, if the target rule has an unreliable expression and only one side of the expression is unreliable, a determination needs to be made as to whether the result will affect the result of the target rule. The result type of the expression is boolean, i.e., true/false, i.e., true or false.
If the influence is made in S341, the target rule is not reliable.
Specifically, if the boolean value of the expression changes, the boolean value of the entire target rule also changes, indicating that the target rule is unreliable.
If S342 is not affected, the target rule is reliable.
Specifically, if the boolean value of the expression changes and the boolean value of the entire target rule does not change, then the target rule is declared to be reliable.
For example, rule (1) is: a > B. Wherein rule (1) is unreliable as long as there is an unreliable indicator in A, B;
if rule (2) is: (A > B) and (C < 1), wherein (A > B) is considered as an M expression and (C < 1) is considered as an N expression.
When rule (2) =true, i.e., the result of rule (2) is true, both the M and N expressions are true, i.e., both M and N have an effect on the final result; the reliability determination of rule (2) in all possible cases is explained as follows:
m=t & & n=t, push out rule (2) =t
M=t & & n=f, push out rule (2) =f
M=f &n=t, push out rule (2) =f
M=f &n=f, push out rule (2) =f
If rule (2) =false, i.e. the result of rule (2) is false, both the M and N expressions are false, i.e. both M and N have an effect on the final result; the reliability determination of rule (2) in all possible cases is explained as follows:
m=t & & n=t, push out rule (2) =t
M=t & & n=f, push out rule (2) =f
M=f &n=t, push out rule (2) =f
M=f &n=f, push out rule (2) =f
If rule (2) =false, M expression-! The expression =n, i.e. false in M and N has an effect on the final result; the reliability of rule (2) is the same as the reliability of the sub-expression false;
assume that: m expression=false, N expression=true, and m=t, push rule (3) =t;
m expression=false, N expression=true, and m=f, pushing out rule (3) =f;
for example, rule (3): (A > B) or (C < 1), where (A > B) is considered an M expression and (C < 1) is considered an N expression.
If rule (3) =true, both the M expression and the N expression are true, i.e., the results in M and N are true and have an influence on the final result; the reliability determination of rule (3) is described as follows in all possible cases:
m=t||n=t, and the push rule (3) =t
M=t||n=f, and the push rule (3) =t
M=f||n=t, and the push rule (3) =t
M=f||n=f, and the push rule (3) =f
If rule (3) =true, M expression-! The reliability of rule (3) is the same as the reliability of the sub-expression true, =n expression;
assume that: m expression=true, N expression=false, and m=t, pushing out rule (3) =t;
m expression=true, N expression=false, and m=f, pushing out rule (3) =f;
if rule (3) =false, both the M expression and the N expression are false, the reliability determination of rule (3) in all possible cases is described as follows:
m=t & & n=t, push out rule (3) =t
M=t & & n=f, push out rule (3) =f
M=f &n=f, push out rule (3) =f
M=f &n=t, push out rule (3) =f
The foregoing is a further detailed description of the invention in connection with specific embodiments, and is not intended to limit the practice of the invention to such descriptions. It will be apparent to those skilled in the art that several simple deductions or substitutions may be made without departing from the spirit of the invention, and these should be considered to be within the scope of the invention.
