Project-Support-System

The problem is to estimate the level of risk involved in a software engineering project. For the sake of simplicity, we arrive at our conclusion based on two inputs: project funding and technical experience for the team members.

Problem Description

The problem of optimal team formation is domestic to many areas of work organization including education, sport, and business. It is beyond manual implementation to build near optimal teams as soon as the pool of available personnel grows into several tens. The selection process itself is usually well defined for each team we construct the criteria relating to the required properties of the team members. Because these properties can be arbitrarily combined in the personnel, the objective function becomes self-conflicting. This aggravates the team formation and calls for specialized software support.

We use quantities values to describe the employees’ capabilities like technical expertise and also to describe the budget limits needed to format a team

The problem is to estimate the level of risk involved in a software engineering project. For the sake of simplicity, we will arrive at our conclusion based on two inputs: project funding and technical experience for the team members.

Suppose our inputs are project_funding and team_experience_level. We can get the fuzzy values for these crisp values by using the membership functions of the appropriate sets.

Sets used

• The sets defined for project_funding are very low (0,0,10,30), low (10,30,40,60), medium (40,60,70,90), high (70,90,100,100).
• The sets defined for team_experience_level are beginner (0,15,30), intermediate (15,30,45), expert (30,60,60).
• The set defined for the risk is high (0,25,50), normal (25,50,75), low (50,100,100).

The Rules

Now that we have the fuzzy values and we can use the fuzzy rules to arrive at the final fuzzy value. The rules are as follows:

1. If project_funding is high or team_experience_level is expert then risk is low.
2. If project_funding is medium and team_experience_level is intermediate or team_experience_level is beginner then risk is normal.
3. If project_funding is very low then risk is high.
4. If project_funding is low and team_experience_level is beginner then risk is high.

Input:

1- First line represents number of input variables = 2 2- Second line gives a Variable Name and its crisp input to fuzzify it later (e.g. project funding 50, experience level 40).

Output:

1- Fuzzifying the inputs 2- Inference of rules 3- Defuzzification output

Test Case

Input:

• Variables: 2
• Project Fund: 50
• Experience Level: 40

Output:

• Predicted Value (Risk) = 66.6
• Risk will be Normal
