  • Essay / A Conceptual Framework for Managing Scheduling Constraints

    Table of ContentsIntroductionBrief Literature ReviewResearch Problem (Explain the particular topic you wish to study)Research ObjectivesResearch QuestionsSignificance of ResearchResearch MethodologyIntroductionEvery construction project is unique and has its own operational environment and sets of technical requirements. As a result, the execution of a construction project is subject to numerous constraints that limit the start or progress of field operations, which invariably has a significant negative impact on the overall project performance. By definition, constraints refer to any conditions, such as temporal/spatial limitations and safety/quality issues, that may prevent a project from achieving its objectives. Successful execution and control of a construction project relies on effective identification and management of constraints through master planning and short-term forward planning. While the master schedule provides an overall view of a project and the overall execution strategy, a forecast schedule provides a detailed account of operational constraints and a detailed plan showing the work to be completed in a relatively short period of time. Ideally, these detailed schedules should reflect actual conditions on the ground and provide field personnel with operating instructions free from constraints and conflicts (Hinze 2008). This advance scheduling and constraint analysis procedure is also an essential element of the last scheduler methodology proposed by Ballard (2000). This research project will provide insight into state-of-the-art practices in analyzing scheduling constraints during advance planning. In addition, it will propose a conceptual framework for managing constraints. Say no to plagiarism.

Limited progress has been made in the overall classification of various constraints based on their characteristics. In terms of modeling and constraint resolution, various approaches have been recommended. For example, many CPM-based methods are applied to manage time constraints; knowledge-based systems were used to automate the generation of work plans; network-based optimization algorithms have been developed to resolve the constraints; and databases and visualization techniques, such as 3D, 4D and virtual reality (VR), are used to communicate and visualize constraints. What is missing in previous studies is a comprehensive and structured approach to managing constraintsResearch problem (explain the particular topic you wish to study)The importance of developing a reliable and constraint-free work plan has been recognized since long by the industry. However, many construction projects are still plagued by delays and cost overruns, which can often be attributed to ineffective identification and treatment of constraints. First, when a constraint is not properly identified during planning, subsequent conflicts on the ground are inevitable. Today's projects are becoming more and more). 2011
