The temporal-relevance temporal-uncertainty model of prospective duration judgment

This paper considers fundamental questions of arbitrage pricing that arises when the uncertainty model incorporates ambiguity about risk. This additional ambiguity motivates a new principle of risk- and ambiguity-neutral valuation as an extension of the paper by Ross (1976) (Ross, Stephen A. 1976. The arbitrage theory of capital asset pricing. Journal of Economic Theory 13: 341–60). In the spirit of Harrison and Kreps (1979) (Harrison, J. Michael, and David M. Kreps. 1979. Martingales and arbitrage in multiperiod securities markets. Journal of Economic Theory 20: 381–408), the paper establishes a micro-economic foundation of viability in which ambiguity-neutrality imposes a fair-pricing principle via symmetric multiple prior martingales. The resulting equivalent symmetric martingale measure set exists if the uncertain volatility in asset prices is driven by an ambiguous Brownian motion.

The construction industry has many underlying causes of uncertainty that impact on late delivery of project completion's performance as well as in time management. Most of researchers proposed a modelling and simulation techniques to solve these uncertainties problem nevertheless not tackling the uncertainty in environmental issues (EI). Yet, the environmental issues were also leading significant deviations for project completion performance, which means it is important to be studied. Therefore, the comprehensive sturvey is discussed in this paper in purpose to develop the uncertainty modeling model on late delivery in environmental issues. The development of conceptual model through a comprehensive survey involving piping's construction industry for water supply company with multi-project construction environment is developed to show the relationship for each cause and affects that underlying uncertainty on late project delivery in environmental issues. Further research is to verify and validate the conceptual model as has been analyzed through fractional factorial design with ANOVA, through the development of uncertainty model via modeling and simulation using MATLAB.
