In some applications of statistical process monitoring, a quality characteristic can be characterized by linear regression relationships between several response variables and one explanatory variable, which is referred to as a 'multivariate simple linear profile.' It is usually assumed that the...

Purpose: This paper employs new methods to evaluate the availability of multistate series–parallel systems, in which a number of similar components are available in each subsystem. Design/methodology/approach: In this paper, polynomial distribution function (PDF) is combined with universal...

This paper presents the location-allocation problem of parking facilities in Mobarakeh Steel Company. The aim is to find the optimal location for the parking facilities and allocate travels between departments to each parking facility. To optimize the cost and facing the transportation demands...

Purpose – The aim of this paper is to consider the effect of gauge measurement capability on the multivariate process capability index ( MC p ). Design/methodology/approach – With respect to measurement capability, the paper investigates the statistical properties of the estimated MC p and...

Purpose The purpose of this paper is to propose a procedure to construct the membership functions for a one-unit repairable system, which has both active and standby redundancy. The coverage factor is the same for the operating and standby unit failure. Design/methodology/approach The α -cut...

Purpose The purpose of this paper is to understand the consequence of the use of mixed Weibull distribution in the cell formation problem. In reliability theory, a mixed distribution is used for more than one hazard cause, and the Weibull distribution can be used for ascendant, monotonous and...

To increase the reliability of a specific system, using redundant components is a common method which is called redundancy allocation problem (RAP). Some of the RAP studies have focused on k-out-of-n systems. However, all of these studies assumed predetermined active or standby strategies for...
