Geologic Prediction Model for Tunneling
Publisher: American Society of Civil Engineers
Abstract: Geologic uncertainty in underground construction often leads to design and construction conservatism and thus to inflated costs. This paper presents a general model for the probabilistic prediction of tunnel geology as a ...
Geologic Exploration and Risk Reduction in Underground Construction
Publisher: American Society of Civil Engineers
Abstract: Geologic uncertainty in underground construction promotes design and construction conservatism and has a significant effect on project cost. Site investigation can reduce this uncertainty and decrease costs by reducing the ...
Evaluation of Subsurface Exploration Programs
Publisher: American Society of Civil Engineers
Abstract: This paper presents a decision support system for the evaluation of geologic exploration programs in underground construction. This system can be used to quantify the economic value of different subsurface investigation ...
Bidding Models—Symmetry and State of Information
Publisher: American Society of Civil Engineers
Abstract: Several competitive bidding models since the late 1960s have been founded, criticized, and even rejected, based on incorrectly stated arguments concerning the apparent symmetry of the competitive positions of the prospective ...
Pilot Tunnels: Contractor's Position
Publisher: American Society of Civil Engineers
Abstract: Geologic uncertainty in underground construction promotes design and construction conservatism and has a significant impact on project cost. Site investigation can reduce this uncertainty and decrease the contingency amounts ...
Dynamic Probabilistic Decision Processes
Publisher: American Society of Civil Engineers
Abstract: This paper presents a general model for the formulation and solution of the risk‐sensitive dynamic decision problem that maximizes the certain equivalent of the discounted rewards of a time‐varying Markov decision process. ...
Risk-Sensitive Competitive Bidding Model and Impact of Risk Aversion and Cost Uncertainty on Optimum Bid
Publisher: ASCE
Abstract: A decision analysis model is presented that can be used by a contractor to determine the optimum lump-sum bid that maximizes expected utility for an upcoming job. Required inputs include the contractor’s utility curve, the ...
Closure to “Average‐Bid Method—Competitive Bidding Strategy” by Photios G. Ioannou and Sou‐Sen Leu (March, 1993, Vol. 119, No. 1)
Publisher: American Society of Civil Engineers
Repetitive Scheduling Method: Requirements, Modeling, and Implementation
Publisher: American Society of Civil Engineers
Abstract: Projects with repeating activities, such as multistory buildings and highways, present unique scheduling challenges. This paper presents the necessary requirements that scheduling systems should address to meet the needs ...
Discussion of “Algorithm for Determining Controlling Path Considering Resource Continuity” by Mohammad A. Ammar and Emad Elbeltagi
Publisher: American Society of Civil Engineers
