Fault tree analysis (FTA) is an effective method of ensuring the security and safety of the product by identifying all the possible causes of the problem and fixing them. However, it is not easy for a designer to construct a complete fault tree about various physical phenomena without any misunderstanding or oversight, and some computerized method of managing (i.e., storing, searching and utilizing) knowledge about FTA is needed. To solve the problem, the authors have proposed and studied a method and software tool for knowledge management of FTA based on quantity dimension indexing as a design knowledge management method to avoid ambiguity of literal expression about physical phenomena. In the previous method and software, however, fault values of quantities were limited as just above- and below-normal, and dynamic phenomena such as oscillation could not be described. In this paper, the authors introduce a systematically classified definition of fault values as above/below normal, one-side/both-sides, constant/varying, monotonic/non-monotonic and sudden/gradual, and expand the computerized systematic approach to FTA. Feasibility of the method was examined by applying it to fault tree examples made in a company.

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.

Construction Safety Management

In mid-2019, there was a construction accident during the underpass construction project in Yogyakarta. The underpass excavation wall in this project was collapsed and 2 vehicles were reported fallen. Although such accident sometimes occurs in some projects, it does not mean that these accidents are caused by the same source. Many efforts to prevent accidents have been done by various methods and one of them is an assessment by observation at construction sites referring to Government Regulation 05 2014 concerning SMK3 (Occupational Safety and Health Management System) in the Public Works Sector Construction. The details about the implementation of construction work are described in PUPR Decree No. 21 in 2019 in term of the Construction Safety Management System (SMKK) Guidelines. This research was conducted to identify factors and indicators of management consultants, supervisors and contractors who have a major impact and contribution to the underpass construction project in Kentungan, Yogyakarta. The percentage level of accuracy in the application of the construction safety management system based on the assessment of the contractor was 85.938% and for the supervisory consultant the percentage level of accuracy was 97.29%. Both percentages are included in the satisfactory category since the assessment ranges are between 85% and 100%. Based on these two assessments, an evaluation was carried out using a Fault Tree Analysis to determine the causality flow of construction accidents.
