“…Sardar Donighi and Khanmohammadi (2011) presented a new model which the reliability of components is as fuzzy set. Taghizadeh and Hafezi (2012) investigated the reliability evaluation of available relationships in supply chain which is suitable for computing reliability of supply chain for organizations. Abouei Ardakan and Zeinal Hamadani (2014b) and Ardakan et al (2015) proposed a new redundancy strategy called mixed strategy which uses both active and cold-standby strategies in one subsystem simultaneously.…”

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 each subsystem. In this paper, for the first time, we propose a k-out-of-n system with a choice of redundancy strategies. Therefore, a k-out-of-n series-parallel system is considered when the redundancy strategy can be chosen for each subsystem. In other words, in the proposed model, the redundancy strategy is considered as an additional decision variable and an exact method based on integer programming is used to obtain the optimal solution of the problem. As the optimization of RAP belongs to the NP-hard class of problems, a modified version of genetic algorithm (GA) is also developed. The exact method and the proposed GA are implemented on a well-known test problem and the results demonstrate the efficiency of the new approach compared with the previous studies.

“…This approach focuses achieving the target and customer satisfaction. Moreover, Supply Chain Operations Reference (SCOR) model is used to evaluate the relationship between supplier, manufacturing and customer in order to measuring the performance more detail into activity of business process [18]. These methods are used to measure supply chain performance and support problem solving of supply chain cases, however the advantages of the methods depend on the scope of the problem.…”

The purpose of this research is the development of a supply chain framework in order to provide the process reference model based on the relationship between entities. This research chooses multiple cases of oil palm refinery in Malaysian because there is a barrier in implementing supply chain strategy in the form of inadequate measurement performance system. The methodology developed in this research comprised three phases involving business process reengineering, supply chain relationship model and performance indicator. There are 35 refineries in the peninsular Malaysia. However, measurement of supply chain performance will be selected in 6 oil palm refineries. The findings show that the conceptual framework can provide an instrument to analyze supply chain performance and evaluate the existing supply chain strategy.

“…Kim and Geshwin (2005) proposed a new model for machines with both quality and operational failures and developed a Markov process-based method for performance analysis of production systems consisting of such machine. Taghizadeh and Hafezi (2012) used supply chain operational reference for investigating the reliability evaluation of available relationships in supply chain. Tan (1999) proposed a method to calculate both average and variance of transient throughput by further assuming that the series system at steady-state is in an irreducible Markov chain.…”

In this study, the analytical probability models for an automated serial production system, bufferless that consists of n-machines in series with common transfer mechanism and control system was developed. Both time to failure and time to repair a failure are assumed to follow exponential distribution. Applying those models, the effect of system parameters on system performance in actual croissant production line was studied. The production line consists of six workstations with different numbers of reparable machines in series. Mathematical models of the croissant production line have been developed using Markov process. The strength of this study is in the classification of the whole system in states, representing failures of different machines. Failure and repair data from the actual production environment have been used to estimate reliability and maintainability for each machine, workstation, and the entire line is based on analytical models. The analysis provides a useful insight into the system's behaviour, helps to find design inherent faults and suggests optimal modifications to upgrade the system and improve its performance.
