“…Common fault tree analysis (FTA) gate symbols and their descriptions [27]. FTA is a top down deductive method that translates physical systems into logical diagrams, showing how equipment failure, human error, and/or external factors can influence an event [27]. Since it was first used in the aerospace industry, it has become an increasingly popular method for people involved in reliability and safety calculations and has extended to industries such as nuclear, power, and chemical processing [28,29].…”

Systematic failure analysis generally enhances the ability of engineering decision-makers to obtain a holistic view of the causal relationships that often exist within the systems they manage. Such analyses are made more difficult by uncertainties and organisational complexities associated with critical and inevitable industrial maintenance activities such as major overhauls, outages, shutdowns, and turnarounds (MoOSTs). This is perhaps due to the ratio of tasks-to-duration typically permitted. While core themes of MoOSTs including planning, contracts, costing, execution, etc., have been the focus of most research activities, it is worth noting that the ability to successfully transfer and retain MoOSTs knowledge is still under-investigated. Effectively implementing a case study-based approach for data collection, the current study explores the harmonisation of various risk assessments (i.e., fault tree analysis and reliability block diagrams) and multicriteria decision analysis (MCDA) tools to investigate perceived barriers to MoOSTs knowledge management and experience transfer. The case study selected for this study is a dual process line all-integrated cement manufacturing plant (the largest of such process configuration in its region). The justification for this choice of industry was driven by the volume and frequency of MoOSTs executed each year (typically 4–1 per process line), thereby providing a good opportunity to interact with industrial experts with immense experience in the management/execution of MoOSTs within their industry. A multilayered methodology was adopted for information gathering, whereby baseline knowledge from an earlier conducted systematic review of MoOSTs practices/approaches provided fundamental theoretical trends, which was then complemented by field-based data (from face-to-face interviews, focus group sessions, questionnaires, and secondary information from company MoOSTs documentation). During the analysis, fault tree analysis (FTA) and reliability block diagrams (RBDs) were simultaneously used to generate the causal relationships and criticality that exist between identified barriers, while the MCDA (in this case analytical hierarchy process) was used to identify and prioritise barriers to MoOSTs knowledge management and experience transfer, based on sensitivity analysis and consistency of approach. The primary aim of this study is to logically conceptualise core barriers/limiters to knowledge in temporary industrial project environments such as MoOSTs, as well as enhance the ability of decision-makers to prioritise learning efforts. The results obtained from analysis of data identify three major main criteria (barriers) and 23 subcriteria ranked according to level of importance as indicated from expert opinions.

“…They support qualitative not quantitative analysis [34] [35] that is why these tools are not preferred for ERP Implementation, the FTA does not consider the severity of failure [36] and in complex system such as ERP that includes large number of equipment and process variables the fault tree becomes lager and takes long time to be completed, and they become much more difficult to solve [34] [37][38], and also these make FTA not a preferred choice, and takes a long time to be completed, and they become much more difficult to solve [34] [37][38], and also these make FTA, not a preferred choice, HACCP is originated in the food industry [39] [40], and hence it is more logic to used it in ERP system Implemented in food industry.…”

The Enterprise Resource Planning (ERP) implementation projects have high failure rates. Any conflict done during the ERP implementation process leads to errors in business decision making, decrease productivity and profitability, and can affect the project success. The main purpose in this paper using Failure Modes Effects Analysis (FMEA) approach to deal with help in increasing the success rate of ERP implementation projects. This achieved through defining main failures and failure factors related to ERP implementations. The ERP projects are divided into three stages; Pre, during and post implementation. Each stage analyzed to define its main characteristics and its different failures and failure factors. Many risks can affect and lead to failure in ERP Implementation. The risk management techniques are very useful before, during and post ERP Implementation phases. The FMEA approach assesses and evaluates the defined failures and failure factors providing a quantitative measure for each risk of failure. Our study describes how to reduce ERP Failures by decreasing the risk value, so the researchers enhance the FMEA approach by a Proposed Enhanced FMEA approach to measure the risk. Based on the four organizational critical areas the researchers' uses four sub categorization aspects, Financial, Customer, Legal & Regulation, and Business Operation. The Enhanced FMEA approach leading to success of ERP implementation.

Abstract:The Fault tree furnishes an engraving and analytical structure to dissect the dependability of systems. A fault tree gives an abstractly essential demonstrating schema to embody the level of system communications among all the component reliabilities in cloud computing environment. Fault tree Investigation is that fundamental technique which concentrates on failure modes for whatever system and the probabilities for occurrence/ likelihood risk dissection connected with it. Fault Tree Analysis signifies to significant deficiency or critical failures connected to the system and reasons for the faults graphically. Here we will realise that likelihood from claiming the failure of the primary event with that assistance about which we get that probability of failure of the top event. Dynamic fault trees include a progressive thought of the conventional issue tree tactic: system failures might rely on component failure. Exceptional motivation dynamic fault tree gates can model gradual supplanting of neglected segments. Starting with pools from claiming spares, failures that happen just if others happen for certain orders, dependencies that propagate failure, also circumstances the place failures could happen best to a predefined request. With the help of the dynamic gates, the fault trees need to be tackled by automatic change with proportional Markov models regularly in a cloud environment. The proposed system uses fault tree analysis and Markov chain process to efficiently identify the repair and failures of each virtual machine and reduces the energy consumption rate and cost accordingly. The result obtained in our proposed model definitely bounds optimum solutions and deceptively specifies the triumph of an efficient fault tree analysis of failures on minimal cost and energy consumption.
