Purpose – The risk factors associated with clients have a major impact on the successful delivery of a project from early design to the construction and operation stages. Risk management studies conducted so far have not succeeded in providing an effective risk assessment methodology for clients in analysing and managing the risk factors that cause both project delays and cost overruns. So, the purpose of this paper is to provide a methodology for a client-based risk management model. Design/methodology/approach – A conceptual framework is designed by integrating the findings from a literature review and a construction industry survey in the Kingdom of Saudi Arabia. The framework includes the risk identification, risk analysis and mitigation strategy, which are the key components of the model. The model of the framework is developed by integrating the analytical hierarchy process (AHP) and Monte Carlo simulation (MCS) underpinned within an @Risk program. Findings – A case study is used to demonstrate the proposed methodology; the results found that the model helps to analyse and quantify the impact of risk factors, and also to assist in taking a suitable risk mitigation strategy, particularly at the early design stage in the construction process. Practical implications – The model is applicable to both public and private clients when they need to know the possible project duration in a new construction project, and to take some proactive actions to avoid the adverse effect of client risk factors at the early stage of the project. Originality/value – The model is expected to help in understanding the nature, and analysing the influence, of client risk factors that cause project delays and cost overruns. The development of the methodology for managing the client-based risk in construction processes at the early design stage is the key value of the study.

Purpose Major changes of an aircraft configuration are conducted during the early design stage. It is important to include the airworthiness regulations at this stage while there is extensive freedom for designing. The purpose of this paper is to introduce an efficient design framework that integrates airworthiness guidelines and documentation at the early design stage. Design/methodology/approach A new design and optimization process is proposed that logically includes the airworthiness regulations as design parameters and constraints by constructing a certification database. The design framework comprises requirements analysis, preliminary sizing, conceptual design synthesis and loads analysis. A design certification relation table (DCRT) describes the legal regulations in terms of parameters and values suitable for use in design optimization. Findings The developed framework has been validated and demonstrated for the design of a Federal Aviation Regulations (FAR) 23 four-seater small aircraft. The validation results show an acceptable level of accuracy to be applied during the early design stage. The total mass minimization problem has been successfully solved while satisfying all the design requirements and certification constraints specified in the DCRT. Moreover, successful compliance with FAR 23 subpart C is demonstrated. The proposed method is a useful tool for design optimization and compliance verifications during the early stages of aircraft development. Practical implications The new certification database proposed in this research makes it simpler for engineers to access a large amount of legal documentation related to airworthiness regulations and provides a link between the regulation text and actual design parameters and their bounds. Originality/value The proposed design optimization framework integrates the certification database that is built of several types of legal documents such as regulations, advisory circulars and standards. The Engineering Requirements and Guide summarizes all the documents and design requirements into a single document. The DCRT is created as a summary table that indicates the design parameters affected by a given regulation(s), the design stage at which the parameter can be evaluated and its value bounds. The introduction of the certification database into the design optimization framework significantly reduces the engineer’s load related for airworthiness regulations.

Delay-risk factors associated with clients in a construction project have a major impact on a successful delivery on time and within budgeted cost. Risk management studies so far have not effectively managed project risk factors in a way that can assist clients in creating strategies to reduce impacts and risk. To address these issues, the study aims to provide a new methodology for analyzing and managing the risks by building a conceptual model. The study includes the development of a framework, named the client risk management model (CRMM), by integrating the findings from a literature review and a construction industry survey. A client risk analysis system was developed by integrating the analytical hierarchy process and a Monte Carlo simulation within an @Risk program. A case study demonstrated the methodology to analyze and quantify the impact of risk factors, and to create a suitable risk mitigation strategy at the design stage of a construction project. The system was found to be useful for quantifying the impact of client risks and the support in taking proactive decisions.

Kaizen Events

Purpose The purpose of this paper is to propose a new framework for early design stage utilizing the benefits of Kaizen events, and Design for Six Sigma (DFSS) methodology. To gain a better understanding of the proposed method, a case study of a diesel engine development was presented where the proposed methodology was followed. Design/methodology/approach This paper proposes a hybrid Kaizen DFSS methodology consisting of four Kaizen milestone events with pre-work preceding these events. The events are in line with the four phases of DFSS methodology (define, characterize, optimize, and verify). Findings In order for the proposed method to succeed, few key enablers should be available such as management buy-in and support, effective resources utilization, and proper planning. However, this methodology should be utilized for key projects where criticality is high and deadlines are nearby. Practical implications As proved by two projects, one of them is presented in this paper; the use of the proposed methodology is effective and can bring significant positive changes to an organization. Originality/value Although Kaizen is an old and well-known process, it is to the best of the author’s knowledge that Kaizen has not been utilized in the early design stages of new product development projects. In this paper, a hybrid methodology combining traditional DFSS systematic approach conducted using Kaizen improvement events is proposed and supported by a real-life case study.

PurposeThis study establishes a risk management system for medical and health care integration projects to address the problem of high-risk potential and a strong correlation between risk factors.Design/methodology/approachA new fuzzy WINGS-G1 model for identifying key risk factors in medical and health care integration projects is proposed by introducing the fuzzy theory and the concept of risk incidence into the Weighted Influence Non-linear Gauge System (WINGS) method.FindingsThe authors analyze the fluidity of project risk factors through complex networks to control direct risks and cut off risk transmission paths to provide a reference for risk control and prevention of medical and health care integration projects.Originality/value(1) The integration of fuzzy theory into the WINGS method solves the problem of strong subjectivity of expert scoring in the traditional WINGS method; (2) By the different probabilities of risk factors, the concept of risk incidence is introduced in the WINGS model, which is more conducive to the identification of the critical risk factors and the rational allocation and utilization of organizational resources; (3) The use of the complex network for risk interactivity analysis fully reflects the dynamic nature of risk factors in medical and health care integration projects.

Detection of potential failures and human error and their propagation over time at an early design stage will help prevent system failures and adverse accidents. Hence, there is a need for a failure analysis technique that will assess potential functional/component failures, human errors, and how they propagate to affect the system overall. Prior work has introduced FFIP (Functional Failure Identification and Propagation), which considers both human error and mechanical failures and their propagation at a system level at early design stages. However, it fails to consider the specific human actions (expected or unexpected) that contributed towards the human error. In this paper, we propose a method to expand FFIP to include human action/error propagation during failure analysis so a designer can address the human errors using human factors engineering principals at early design stages. To explore the capabilities of the proposed method, it is applied to a hold-up tank example and the results are coupled with Digital Human Modeling to demonstrate how designers can use these tools to make better design decisions before any design commitments are made.

Purpose The purpose of this paper is to empirically compare the risk factors in public-private partnership (PPP) projects in developing and developed countries, represented by Ghana and Hong Kong, respectively. Design/methodology/approach A structured questionnaire survey was conducted with PPP practitioners in Ghana and Hong Kong. In total, 103 valid responses were received for analysis. Kendall’s coefficient of concordance and mean ranking were used for data analysis. Findings The results show that respondents from Ghana ranked country risk factors higher, whereas their Hong Kong counterparts ranked project-specific risks higher. The top five significant risks in Ghana are corruption, inflation rate fluctuation, exchange rate fluctuation, delay in project completion and interest rate fluctuation. In Hong Kong, the top five significant risk factors are delay in land acquisition, operational cost overruns, construction cost overruns, delay in project completion and political interference. Originality/value The results of the study inform international investors of the appropriate risk mitigation measures and preventive actions to use when engaging in PPP arrangements in any part of the world. Further, governments who are yet to use the PPP concept would be informed of the prevailing risk factors in other neighbouring countries (i.e. developing or developed countries).
