IMPROVING SOFTWARE COST ESTIMATION WITH FUNCTION POINTS ANALYSIS USING FUZZY LOGIC METHOD

— Function Points Analysis (FPA) is amongst the most generally used method to assess software cost estimation frameworks. This process speaks to the measurement of an undertaking, application, and function by its relative functional complexity. In general, it has numerous effective applications used in both industry and scholarly research. This is noticed that customized estimate technologies which can confront genuine challenges utilizing on programming building information is normally constrained, loosely gathered and deficient. To enquire these queries composite programming models, blend of information, fuzzy logic and master judgment is proposed. This is trusted that outcomes announced here will animate, renew investigation of fuzzy logic to genuine programming designing issues. In this research paper, we use Function Points and apply some new models to pick up a superior estimation of programming properties. The utilization of ideas and characteristics from the fuzzy set hypothesis to stretch out function points analysis to fuzzy function points analysis. Fuzzy hypothesis tries to construct formal quantitative arrangement equipped for imitating imprecision of the human information. With the function points created by Fuzzy FPA, an estimate value for example, expenses/cost and software development can be more correctly determined.

general system characteristics (GSCs), the data input received from external input, external inquiry, external output and internal logical file (that is, the functionality demanded by and providing to the end consumer), of a software against the standard criteria.
Albrecht initially proposed five function kinds (inputs, inquiries, outputs, interfaces and files) with one lot of related loads. In 1983, work created in [10], proposed extension of function kind, a set of three weighting esteems (for example low, medium, high) known as complexity of software project as shown in Table-I. Fourteen (14) General System Characteristics (GSCs) were suggested known as processing difficulty of software project as given in the Table-II. The Unadjusted Function Points count (UFC) is given below:

Figure-2 represents the Fuzzy Logic Model.

II. LITERATURE REVIEW
For venture offering, planning and arranging are the premise and endeavors gauges by Software improvement, poor planning and arranging regularly has sensational results, and these are fundamental practices in the product business [14]. 15 percent of the product ventures are never finished because of the gross misestimating of improvement exertion and 60 percent of enormous tasks fundamentally overwhelm their evaluations in Boraso report [15]. For programming associations, conveying a product item on schedule, inside financial plan, and to a concurred degree of value is a simple concern. For better arranging, checking and control precise appraisals are significant [16]. In the writing new suggested cost estimate work execution is contrasted and related tasks.

To get most extreme execution, in the investigation same adjustment on the creation work is made all together [17].
Reason for the exploration is to suggest structure for developing product cost estimate model for the programming change venture dependent on social framework of an undertaking outline and programming cost utilizing relationship estimation technique and numerous relapse examination to gauge measure of programming alteration list and measure of exertion demanded for new task from information assortment of past undertaking [18].
In this examination for programming cost estimation a  [24][25][26][27] applied counterfeit neural system to cost estimation. Neural system can sum up from prepared informational collection.
Over a lot of preparing information, neural system learning calculation builds mappings that fits information, and fits beforehand inconspicuous information in sensible way. [28] An The upsides of fuzzy rationale are joined learning capacity and great speculation got. The principle advantage of this methodology is it has acceptable interpretability rules.
The exertion anticipated utilizing nine principles will be contrasted and Albrecht Dataset. illustrates.
New language variable is created by TFN (a, m, k)

B. Proposed Technique
Soft Computing/Machine learning is a range of research that arrangements with genuine issues in a more powerful 1. If (Processing Complexity is Simple) and (Complexity is Low) THEN (Effort is Very Small).

IF (Processing Complexity is Average) and
(Complexity is Low) THEN (Effort is small).

IF (Complexity is Low) and (Processing Complexity
is Complex) THEN (Effort is Medium).

IF (Processing Complexity is Simple) and
(Complexity is Medium) THEN (Effort is small).

IF (Processing Complexity is Average) and
(Complexity is Medium) THEN (Effort's Medium).

(Complexity is high) THEN (Effort is Medium).

IF (Processing Complexity is Average) and
(Complexity is high) THEN (Effort is Large).

IF (Processing Complexity is Complex) and
(Complexity is high) THEN (Effort is Very Large).
The model is capable of utilizing two input factors and apply predefined fuzzy rule base to get an accurate prediction of fuzzy function points and software efforts. The results thus produced are compared with Function Points. The trouble with FP is that when applied to the records from Albrecht dataset, it tends to misinterpret, both over as well as under.
Whereas, the proposed model when applied to the same dataset produce results that are very much aligned with the actual results given with the records. Fig-5 shows a screenshot of proposed FIS developed using Matlab 2014a.

IV. Experiments and Results
Extensive experimentation has been done to assert the suitability of the proposed methodology as compared to current methodologies found in the literature. Vast amount of data available through the dataset makes it relatively straightforward to experimentally analyze various available techniques.

IV. CONCLUSION
By research, it has been proven that by combing these two methods a new method can be developed that would prove to be an effective method system.
