Dynamic Staffing and Rescheduling in Software Project Management: A Hybrid Approach

Yujia Ge, Bin Xu, Yong Deng
2016 PLoS ONE  
Rescheduling happens commonly and frequently during the project execution. Control options have to be made when new resources are added or tasks are changed.  ...  Resource allocation could be influenced by various dynamic elements, such as the skills of engineers and the growth of skills, which requires managers to find an effective and efficient tool to support  ...  We also propose a software project rescheduling approach considering efficiency and stability.  ...

Forhad Zaman, Saber Elsayed, Ruhul Sarker, Daryl Essam
2020 IEEE Access  
Resource-constrained project scheduling is one of the most widely studied research problems.  ...  This paper investigates different cost-effective measures for project scheduling problems under resource disruptions, in which the disrupted resources are dynamically recovered as the project progresses  ...  Therefore, the project manager may have to reschedule activities in order to complete the project efficiently.

What about Train Length and Energy Efficiency of Freight Trains in Rescheduling Models?

Ambra Toletti, Valerio De Martinis, Ulrich Weidmann
2015 Transportation Research Procedia  
The first aim of this paper is to investigate how current scheduling and rescheduling models consider train length and energy efficiency.  ...  The second aim is to extend a scheduling model that considers train length and energy efficiency for drafting a rescheduling model that minimizes not only delays but also energy consumption.  ...  Though, the EU showed particular attention to even longer freight trains, e.g. project Marathon (NEWOPERA Aisbl, 2014) , in order to reduce costs and improve efficiency in operation.  ...

Robust and reactive project scheduling: a review and classification of procedures

Willy Herroelen, Roel Leus
2004 International Journal of Production Research  
Predictive-reactive scheduling refers to the process where a baseline schedule is developed prior to the start of the project and updated if necessary during project execution.  ...  We also offer a framework that should allow project management to identify the proper scheduling methodology for different project scheduling environments.  ...  Rescheduling Rescheduling may use any deterministic performance measure, such as the new project makespan (in manufacturing systems, this approach is sometimes referred to as (complete) regeneration).  ...
