概要 （英文）

ELECTRIC UTILITIES ARE INCREASINGLY DEVELOPING NEW TYPES OF SOFTWARE-BASED SYSTEMS SUCH AS KNOWLEDGE-BASED SYSTEMS OR NEURAL NETWORKS. HOWEVER,WOULD-BE USERS OF THESE SYSTEMS FACE THE ISSUE OF QUALITY ASSURANCE BECAUSE THE DEVELOPERS DO NOT PROVIDE QUALITY ASSURANCE AT THE SAME HIGH LEVELS AS CONVENTIONAL SOFTWARE DEVELOPERS. THE REASON IS MAINLY LACK OF A SYSTEMATIC PROCESS THAT PREVENTS AND DETECTS FAULTS AT EVERY STEP OF DEVELOPMENT. THIS REPORT DESCRIBES A METHODOLOGY NAMED FAULT REDUCTION METHODOLOGY THAT PROVIDES SUCH A PROCESSFOR REDUCING THE NUMBER OF FAULTS IN SOFTWARE BY USING CASE TOOLS. THEMETHODOLOGY IS BASED ON ENUMERATION OF FAULT TYPES AND ANALYSIS OF PREVENTIVE AND DETECTIVE METHODS FOR EACH TYPE OF FAULT. THE METHODOLOGY REDUCES THE POSSIBILITY OF FAULTS BY FOUR STEPS. (1)DESIGN A DEVELOPMENTPROCESS COMBINING SOFTWARE LIFECYCLE COMPONENTS CALLED KERNELS CONSIDERING FEATURES OF THE DEVELOPED SYSTEM. (2)SELECT REPRESENTATIONS OF THEARTIFACTS OF SOFTWARE KERNELS BASED ON FAULT CONTROL LEVEL FOR EACH REPRESENTATION TO REDUCE THE PROBABILITY OF FAULTS. (3)SELECT A SET OF V&V METHODS TO DETECT IDENTIFIED IMPORTANT TYPES OF FAULTS EFFECTIVELY BASED ON AN EFFECTIVENESS MEASURE. (4)USE CASE TOOLS THAT SUPPORT SELECTED REPRESENTATIONS OR V&V METHODS EFFECTIVELY.
