Warning Messages

Researchers are investigating a broad spectrum of factors affecting positively and/or negatively the evacuation decision-making process occurring after people at risk receive cyclone warnings and advisories. Previous studies suggest that early warnings themselves do not propagate evacuation processes to be investigated but, rather, that human risk perceptions do so. This in turn encourages the sociopsychological dimensions of risk perception to be evaluated, which must be done within a country’s own cultural context. In applying content analysis here, we review the literature on evacuation decision-making processes during rapidonset hazards, i.e., tropical cyclones, in coastal Bangladesh. We focus on three broad overlapping themes – early warning, risk perception, and evacuation decision-making. Major content-analysis findings suggest that two things – a lack of credibility in early warning messages and an inefficient dissemination process – tend to affect the risk perception of people at risk and are likely to eventually determine the success of evacuation decision-making. Findings also show that different socioeconomic and socio-cultural issues related to risk perception appear to be more influential than formal warning messages in propagating decisions to evacuate during a cyclone. Based on these results, we suggest specific policy recommendations for improving local evacuation efficiency.

Pros And Cons

Various Multiple Criteria Decision Making (MCDM) methods are being commonly used in the area of construction risk management to deal with decisions that are subjected to several factors affecting the selection of the best possible choice in the projects. There are many techniques developed to provide assistance to decision-makers during decision-making process, each having different advantages and disadvantages. This study discusses some of the most frequently applied MCDM methods in construction risk management such as: AHP, ANP, TOPSIS, VIKOR, and DEMATEL, with their own application principles. It aims to introduce a meta-analysis about the use of MCDM methods within the last two decades and provide an extensive literature review study about construction risk management. It is expected to assist practitioners and researchers to suggest effective methods for specific type of risks to be addressed in construction projects. The discussion of pros and cons of each method will also provide some insights to get use of multiple MCDM methods rather than a single means to enhance the analysis outputs.

Improved Performance

Prefabricated construction has been widely accepted as an alternative to conventional cast-in-situ construction, given its improved performance. However, prefabricated concrete building projects frequently encounter significant delays. It is, therefore, crucial to identify key factors affecting schedule and explore strategies to minimise the schedule delays for prefabricated concrete building projects. This paper adopts the decision-making trial and evaluation laboratory (DEMATEL) model and analytic network process (ANP) method to quantify the cause-and-effect relationships and prioritise the key delay factors in terms of their importance in the Chinese construction industry. The DEMATEL model evaluates the extent to which each factor impacts other factors. The quantified extents are then converted into a prioritisation matrix through ANP. The delay factors of prefabricated construction projects are selected and categorised based on a literature review and an expert interview. Questionnaires are then implemented to collect the data. The results reveal that the issue of inefficient structural connections for prefabricated components is found to be the most significant factor and most easily affected by other delay factors. This research also suggests prioritising major delay factors, such as ‘lack of communication among participants’ and ‘low productivity’, in the Chinese construction industry during scheduling control. Overall, this research contributes an assessment framework for decision making in the scheduling management of prefabricated construction.

Potential Factors

Deciding whether bid for the construction project is classic risk-based decision-making that is crucial to the survival and prosperousness of construction companies. More contractors are adopting group bidding decision-making to reduce the number of incorrect decisions. However, previous related studies mainly focus on project factors that overlook the members of bidding groups and the interaction between bidding group members. The aim of this paper, therefore, is to investigate the potential factors that influence group bidding decision-making for construction projects. Twenty factors relating to individual, group, and organizational levels are identified through a literature review and interviews with experienced practitioners. A questionnaire survey of 203 Chinese international contractors is conducted to obtain the importance of the factors involved. The results of the ranking analysis indicate 14 critical factors, among which “risk perception” and “team decision preference” are regarded as the two most significant. Moreover, 20 factors can be classified into five groupings: (1) values and strategic goals, (2) collaboration and learning orientation, (3) consensus reaching, (4) risk awareness, and (5) empowerment and development, with risk awareness having an especially strong influence. This research deepens the understanding of factors belonging to different organizational levels that need to be highlighted during the group bidding decision-making process and provides strategies for bidding groups and their companies to improve their decision performance.

Online Buying

The e-commerce growth and development in Indonesia is very rapid as well as the internet grows, but it is not well-balanced with the number of online buying transaction which is still relatively low. Even the today’s biggest B2C e-commerce people in Indonesia, Lazada, has continually decreased online purchasing. This research is aimed to describe factors affecting online buying decision- making in the e-commerce Lazada. The type of this research is confirmatory research. The variable used is following conceptual model i.e. Electronic Word of Mouth (EWOM), social identity, risk perception, trust, and purchase intention. The data were obtained through the questionnaire with Likert scale 1-5. There are 104 people researching sample who meets the criteria as Lazada consumer that, at least do a transaction in recent six months. Data analyzing were done using Structural Equation Modelling (SEM) method by Analysis of Moment Structures (AMOS) software. The results showed that the purchase intention has positively related to the purchase decision. Variable EWOM toward trust has positive relation, variable social identity and risk perception have no any significant relation to trust. Variable risk perception toward purchase intention has no significant relation, while the variable trust has significant positive relation to purchase intention.

Timely Completion

Risk is inherent in construction projects and managed through contingency. Dynamic management of contingency escrow accounts during project execution poses decision-making challenges. Project managers use key performance indicators (KPIs) for contingency release decisions. However, their subjective mental models influence risk perception, exacerbating the decision-making dilemma. This research integrates project KPIs with future risk perception to develop a mathematical model for facilitating such decision making. Results suggest timely completion, project cost, stakeholder satisfaction, quality and safety as top KPIs, and the influence of managerial pressure as a significant decision contributor. The proposed model helps project managers in dynamic decision making for cost contingency.
