Enterprise resource planning (ERP) projects are very complex tasks, expensive, time-consuming, and risky investments. One of the main reasons for the high ERP project failure rate is that managers don't assess and manage the risks involved in these projects. In addition, they don't know the importance degree for each of these risks. On the other hand, to the best of our knowledge papers proposing...
This paper proposes an integrated approach to identify, evaluate, and improve the potential failures in a service setting. In this paper a new integrated approach is developed to improve the method of Service Failure Mode Effects and Critically Analysis (FMEA) from an economic perspective. The contribution of this paper is that it combines a fuzzy cost-based FMEA, GRA (grey relational analysis) and...
Risk and uncertainty are considered crucial and extremely problematic for economic and industrial systems. They must be handled with preciseness so that decision makers need first to establish an action plan for their mitigation by estimating the associated low frequency of failures and adverse events. This paper proposes a combination of solutions based on reliability estimation using enumerating...
In maintenance engineering, it is intended that in a Block Replacement Policy (BRP) model, items are removed and replaced by new ones at failure and at the beginning of each scheduled time kT (fe = 1, 2, …). It was proved that this kind of strategies has its limits and didn't cover others particular situations. This paper addresses a modified BRP model, that in the same conditions, instead of using...
Network reliability analysis problem is the center of many scientific productions. It consists of evaluating the all-terminal reliability of networks. Two classes have emerged; exact and approximate methods. The aim of this paper is to present an efficient exact method for enumerating minimal cuts (MCS) of R-networks. The algorithm proceeds by determining minimal paths set (MPS) and from which minimal...
