A construction project is an activity that aims to build facilities and infrastructure within the planned timeframe. The can be defined as organized effort or uses available budget resources must achieved achieve important goals, objectives, expectations using existing resources, which completed timeframe so does not experience delays. purpose of this study was determine how much work delays, f...

In this study, we aim to present a new model for the resource-constrained project scheduling problem (RCPSP) considering a working calendar for project members and determined the skill factor of any member using the efficiency concept. For this purpose, the recyclable resources are staff resources where any person with multiple skills can meet the required skills of activities in a given time. ...

Changes in a construction project schedule can impact the project’s planned duration, resulting penalties. A manual trial-and-error probabilistic approach is usually conducted to find an appropriate set of corrective measures mitigate delays overall project. However, this does not capture actual goal-oriented behavior managers who react scenarios causing delays, leading fundamental modeling err...

A short-range, easily deployable data communication system enables numerous highway work zone applications. The Kansas Department of Transportation is currently funding a project to develop a delay notification system in rural construction zones. The objective of the project is to estimate the expected delay until the return of the pilot car and communicate that delay to motorists waiting in th...

The current final project belongs to a subject in the master’s degree in Advanced Mathematics at the University of Barcelona. It deals with time delays which usually are arisen in differential equations. Firstly, the project develops the main important known results of Delay Differential Equations, which are a specific case of Functional Differential Equations. In particular, we shall also focu...

Modern construction projects commonly suffer from delay in their completions. The resolution of time and cost claims consequently flowing from such delays continues to remain a difficult undertaking for all project parties. A common approach often relied on by contractors and their employers (or their representatives) to resolve this matter involves applying various delay analysis techniques, w...

In this paper we investigate in detail the properties of a dynamic resource allocation scheme that utilizes online measurements to optimally adjust scheduling weights and to achieve the required QoS, under a given pricing structure. Extending our previous work, we consider here an additional important QoS parameter, namely, the average queueing delay, in order to provision favorable QoS guarant...

The paper develops a theory for equity premium around macroeconomic announcements. Stock returns realized around pre-scheduled macroeconomic announcements, such as the employment report and the FOMC statements, account for 55% of the market equity premium during the 1961-2014 period, and virtually 100% of it during the later period of 1997-2014, where more announcement data are available. We pr...
