Application Of Intuitionistic Fuzzy Topsis Model For Troubleshooting An Offshore Patrol Boat Engine

In this paper, an Intuitionistic Fuzzy TOPSIS model which is based on a score function is proposed for detecting the root cause of failure in an Offshore Boat engine, using groups of expert’s opinions. The study which has provided an alternative approach for failure mode identification and analysis in machines, addresses the machine component interaction failures which is a limitation in existing methods. The results from the study show that although early detection of failures in engines is quite difficult to identify due to the dependency of their systems from each other. However, with the Intuitionistic Fuzzy TOPSIS model which is based on an improved score function such faults/failures are easily detected using expert’s based opinions

Interval-Valued Intuitionistic Fuzzy Topsis-Based Model For Troubleshooting Marine Diesel Engine Auxiliary System

In this paper, we present an interval-valued Intuitionistic Fuzzy TOPSIS model, which is based on an improved score function for detecting failure in a marine diesel engine auxiliary system, using groups of experts’ opinions to detect the root cause of failure in the engine system and the area most affected by failures in the diesel engine. The improved score function has been used for the computation of the separation measures from the intuitionistic fuzzy positive ideal solution (IFPIS) and intuitionistic fuzzy negative ideal solution (IFNIS) of alternatives while the criteria weight have been determined using an intuitionistic fuzzy entropy. The study is aimed at providing an alternative method for the identification and analysis of failure modes in engine systems. The results from the study show that although detection of failures in Engines is quite difficult to identify due to the dependency of the engine systems on each other, however using intuitionistic fuzzy multi-criteria decision-making method the faults/failure can easily be diagnosed

These misconducts and unethical operations have been escalating and expanding in number, operations, and sophistication in recent years and are mostly common in the developed economies

Effect of Lean Tools to Control External Environment Risks of Construction Projects

Among the existing management concepts and methods implemented for solving construction project delays is the integration of lean tools in the construction project cycle. While these lean tools are said to minimize delays and improve project delivery processes, most have been conceptualized to assess aspects of the lean tools. However, to ensure suitability and applicability, and thus, the success of lean tools implementation, there is the need for identification and appropriate prioritization of the lean tools. This paper proposes a novel delay control framework based on AHP method for the evaluation of lean tools application in the external environment (political, economic, social, technological, legal, and environmental aspects) of construction projects. To extend the qualitative data, six main delay sources and forty lean tools were extracted from the existing literature for further empirical inquiry. The results of the framework indicated that the most effective lean tools were concurrent engineering, last planner system and daily huddle meetings with priorities 0.425235, 0.379652 and 0.371172 respectively. Meanwhile, the least influenced lean tool was found to be SMART Goals with priority 0.026566. This framework, would provide a decision tool for practitioners to determine appropriate lean tools to control specific delay sources

Analytic Hierarchy Process Decision Making Algorithm

Decision making in today's world certainly incorporates the consideration of assessment in view of a number of criteria, instead of a favored single criteria. Solving a multi-criteria decision issue offers decision makers suggestions, regarding the best decision choices (Alternatives). At the point when discovering the best decision of alternatives, subject to various distinctive criteria is almost impossible, the Analytic Hierarchy Process (AHP) has been very instrumental, effective, extraordinary and much of the time utilized strategy in solving problems in much complex decision making processes. This paper briefly discusses Multi-Criteria Decision Making (MCDM) and AHP as one of the most popular MCDM methods for group decision making. Also, steps, techniques and formulae used in AHP have been discussed to help handle the problems arising from choosing alternative(s). Finally, the paper offers recommendations to researchers and professionals to apply AHP methodology techniques when analyzing multiple, complicated and conflicting decision making problems

Lean Construction: An Effective Approach for Project Management

red within a specified time. It has been asserted by a number of researchers that fast, complex and uncertain projects cannot be managed through the conventional ways and that fast track projects with long, complicated supply chains involving many players and subject to multiple, extensive process design changes have complex flow management that have failed miserably. The conceptual models of construction management and the tools it utilizes (work breakdown structure, critical path method, and earned value management) have been criticized to be deficient in handling the present unique challenges of projects. As a result, the industry is characterized by a number of wastes including: overproduction, lead time, transportation, inappropriate processing, inventories, unnecessary movements, rework and making do wastes. There is therefore the need for practical and robust models and techniques that will help projects teams deal with the issues of wastes in projects. This can only be achieved through the adoption of lean production systems in the construction industry, thus, Lean Construction (LC). In this paper, LC approach and the importance for its implementation has been discussed as the robust approach for project management

Unethical Admissions: Academic Integrity in Question

The increasing unethical practices of graduates’ admissions have heightened concerns about the integrity of the academy. This article informs this important subject that affects the students, admission systems, and the entire scientific community, thus, representing an approach against scholarly black market activities including falsified documents and unethical practices by consultants and students’ recruitment agencies

4P delays in project management

Purpose - As a result of the increasing challenges of time overrun, several companies regularly set up delay assessment procedures for performance improvement and profit maximization. In the construction industry, projects are enormously complicated and involve significant budgets, and therefore optimizing project performance through the root cause analysis should be imperative for every project manager. Typically issues of delays in projects are generally discussed and problematized separately, yet a comprehensive framework for systematic analysis and grouping of delays is rarely contended. The purpose of this paper is to introduce the 4P concept (project related, practices, participants, and procurement) for identifying, analyzing, and classifying delays in the internal environment of the project development process. Design/methodology/approach - The 4P conceptual framework was validated through the synthesis of the existing literature. Findings - Interestingly, despite the increasing concerns about delays in the construction industry, most research on delays are project and/or country specific, thus no consensus about the sources of delays. The application of the proposed concept as a theoretical framework would provide an understanding of the available delay sources, their risks and use for project delay assessment and classification. Research limitations/implications - This study grouped delays based on the shared characteristics and four main sources were identified and analyzed. There may be other sources or factors, yet would be dependent or aspect of the 4P. Practical implications - The study informs project teams to reduce delays in the construction industry. Originality/value - The paper is an application of risk assessment tool to conceptualize delays in the internal project environment

The paper begins with a review of delays in construction projects, trending methodologies and techniques, and highlights the potential for applying the strategies: Building Information Modeling (BIM); Computer Integrated Manufacturing (CIM); Production/Lean Techniques; Skill Development and Training; and Concurrent Supply Network (CSN). Extensive use of these approaches in many countries has proven its efficiency in construction project development process’ improvement and the overall performance of the building industry

Assessment of Environmental Risks in Construction Projects: A Case of Malaysia

Risk management is a concept which is increasingly becoming exceptional in a number of organizations. Several companies regularly set up a risk assessment procedure for performance improvement and profit maximization. In the construction industry, projects are enormously complex in nature and often involves significant budgets, and therefore reducing risks associated with project development should be key for every project manager. In this paper, risks associated with external sources have been identified and investigated in a case study. The analysis of the risks has been presented using risk priority number (RPN) to determine the failure modes in projects. From the results, the top risks included availability of labors, lack of technical know-how , use of old methodologies, inefficient dissemination of information, changes in government regulations, unrealistic contract time frame, licensing, permit, documents approvals, change of government department heads, bribery and corruption, difficulty in accessing credit facilities, obsolete technology and tools, market competition and conditions, inertia in government bureaucracies, changes in taxes, and import and export restrictions. This study aims to provide a decision tool for establishing failure modes and their priorities in Malaysian construction projects, thus, avoiding the major costly impact of the risky variables to projects in terms of budget, time and quality considering the scarce resources of construction companies
