Design/methodology/approach This research presents the derivation and uses the numerical study to compare the calculated probability of acceptance and the minimum sample size when using the present design concept of binomial distribution with true fraction of nonconforming...

...Valerie G. Caryer Cook; Ahad Ali Purpose This paper aims to propose the use of net present value methods to derive the quality costs of quality improvement projects. The proposed methodology is then demonstrated in a case study of a quality improvement to an inspection process in an automobile...

... inspections can help detect deterioration at an early stage and prevent failure. However, inspection is also expensive. The challenge is to develop a model that keeps inspection costs to a minimum while ensuring that the equipment down time is prevented or minimised. This paper first develops a model based...

... available with the system and inspects the operation of the sensing device. If the device is not working, then an expert repairman is called to the system and the operational status of the unit is now monitored by the expert repairman. It is assumed that the failure of the unit, repair of the regular...

...M. Ben‐Daya; M. Hariga In this paper, we develop a model for machine maintenance inspection problem. Conditions under which an economical solution exists are derived. An optimal solution procedure yielding the optimal inspection interval length in few iterations is proposed as well as a closed form...

...Kyoumars Bahrami‐Ghasrchami; J.W.H. Price; J. Mathew For manufacturing systems which are in continuous operation and subject to breakdown, inspection can be an appropriate maintenance strategy. In this situation, inspection can reduce down‐time and increase system reliability. In this paper two...

...Dradjad Irianto Inspection for quality of product is performed mostly at the end of the production line. Therefore, non‐conformance is known at the time it is inspected. One solution is applying in or between process inspection. Moreover, in or between processes the required correction can...

Vaurio Solving an optimal test or inspection interval is a relevant problem for a machine that is subject to random failures when failures can only be revealed by periodic inspection or testing. Frequent testing increases the testing costs, while infrequent testing leads to increasing...
