Cost Objective Model for Construction Equipment Replacement Policies
Abstract: Most construction companies, particularly companies whose projects are primarily constructed with earthmoving equipment, depend heavily on their construction equipment fleets, which represent substantial locked capital investment and require acceptable utilization levels to recover expenses incurred and losses from this investment. The equipment, which possesses a finite physical and economic life, inevitably requires replacement, and equipment maintenance costs increase with the equipment life. Different methodologies are employed to establish the replacement …

Risk Based Estimation in Construction Projects
Abstract: Final cost of a project is always subjected to many variables and assumptions. A single value estimate only represents one of the many possible conditions that can arise in the future. Hence a cost estimate should be represented as a range of values rather than a single value. Construction projects are complex project which involve many uncertainties. Uncertainties in activities can be a threat to the project objective or an …

Comparative Realization of 2DoF PID Controllers for Flow Process with Measurement Delay
Abstract: Two Degree-of-Freedom (2DoF) PID control techniques presented in this paper were developed based on optimal control theory and with the Anti-Integral Windup (AIW) scheme. The controllers were implemented for a laboratory flow process setup. First Order Process with Dead Time (FOPDT) models had been identified by step testing. The process responses showed a significant non-minimum phase dynamics exhibited for the specific step inputs applied. The measurement delay was considered as …

Anti-synchronization of Vallis System using Sliding Mode Control
Abstract: This paper is concerned with anti-synchronization of Vallis system (talks about fluctuations of temperature in western and eastern parts of near-equatorial area of the ocean). Sliding mode control is proposed to achieve the proposed anti-synchronization. A proportional integral switching surface is devised with appropriate control law and reduction of chattering is considered as well. Simulation results are given for verification and effectiveness of the proposed scheme. Simulation results reveal that …
