Safety critical systems are those systems whose failure could result in loss of life, significant properityda mage, or damage to the environment. Brake-by-wire (BBW) technology in automotive industry is the ability to contr ol brakes through electrical means. It can be designed to supplement ordinary service brakes or it can be a standalone brake system. The increasing usage of brake-by-wire sy...

a manufacturing process cannot be released to production until it has been proven to be stable. also, we cannot begin to talk about process capability until we have demonstrated stability in our process. this means that the process variation is the result of random causes only and all assignable or special causes have been removed. in complicated manufacturing processes, such as drilling proces...

a r t i c l e i n f o Keywords: Failure mode and effects analysis Data envelopment analysis Overall risks Risk priority ranking Failure mode and effects analysis (FMEA) is a method that examines potential failures in products or processes and has been used in many quality management systems. One important issue of FMEA is the determination of the risk priorities of failure modes. In this paper ...

An ontology for representing operating, safety and control procedures is proposed in this paper that supports diagnosis based on following these procedures and combining observed malfunctions with Failure Mode and Effects Analysis (FMEA) information. The procedure ontology is defined within interconnected components of the process plant, diagnostic analysis (where the FMEA is described) and pro...

Nonparametric control charts are presented in order to figure out the problem of detecting changes in the process median (or mean)‎, ‎or changes in the variability process where there is limited knowledge regarding the underlying process‎. ‎When observations are reported imprecise‎, ‎then it is impossible to use classical nonparametric control charts‎. ‎This paper is devoted to the problem of c...
