“…Several tools and techniques have been computerized and integrated with more advanced simulation models and algorithmic approaches for scheduling of project-based resource constraints as demonstrated by, for example, Abeyasinghe, Greenwood, and Johansen (2001); Lim et al, (2011); Liu and Wang (2012); Long and Ohsato (2008); and Trietsch and Baker (2012). These authors have investigated issues with networkbased mathematical algorithms and modeling.…”

Despite attention being paid to the development of planning and scheduling theory, it is unclear whether project stakeholders and practitioners have sufficient understanding about how it applies in practice. A study was conducted with the aim of assessing practitioners' perceptions of planning and scheduling theory and practice on construction projects in Oman. Data were gathered through a questionnaire-based survey and analyzed using the relative importance index. Respondents were asked to consider: (1) the suitability and efficiency of existing planning methods; (2) scheduling development and performance control; and (3) knowledge-based planning and scheduling concepts. The analysis revealed no significant variations among respondents' perceptions in regard to the above topics. The findings did, however, reveal a number of factors that are of equal importance to the development of project planning and scheduling. The overall findings imply that practicing managers should implement new management strategies that foster knowledge-based planning and scheduling concepts for a more effective construction process. Recommendations are made for improvement that include the need for practicing managers to professionalize project planning and scheduling based on a more proactive and knowledge-based planning approach, which is supported by management.

In construction projects, resource availability might limit the implementation of ideal schedules. Especially, when repetitive activities are involved, traditional resource‐constrained project scheduling problem (RCPSP) models fail to allocate the resource consumption in an efficient manner. Besides, actual models only provide local optimal solutions and do not incorporate activity acceleration routines. To fulfill this gap, partially, a mathematical optimization model, the multimode RCPSP for repetitive activities in construction projects, is proposed and solved to optimality; it takes into account acceleration routines under real construction scenarios using spreadsheets. The article shows a complete computational experimentation over a real construction project, considering several scenarios of resource availabilities and continuity conditions. The model allows analyzing the resources efficiency indexes comparing them to resource consumptions, continuity of activities, and objective functions that reveal that fragmented activities do not provide better resource efficiency outcomes.
