can anyone help me in creating a employee stack ranking with dummy data?

Parameters which You need to use is : attendance(No.of present against no of working days)Production,Quality and No of errors..

The parameters should have certain weightage scores like if the employee reach Quality score of 98% then it should have weightage scores of 50 else it should be less than that.In the same way other parameter should be set for different weightage scores.

Please help in preparing this.

Thanks,
