Improving Effectiveness of Constraints Removal in Construction Planning Meetings: Information-Theoretic Approach

A Mechanism for Smart Contracts to Mediate Production Bottlenecks Under Constraints

“…Koskela (1999) suggested that at least seven types of constraints should be removed during construction planning: construction materials, tools and equipment, laborers, prerequisite work, design and working methods, space, and weather. While the constraints widely exist in practice, it takes construction professionals significant time and effort to identify and eliminate them to achieve the desired production pace and reliable workflow (Javanmardi et al, 2020). In the past decades, it has been shown that constraint removal has a significant relationship with workflow reliability (Jang & Kim, 2008).…”

“…This study aims to improve production flow by modeling potential scenarios integrated with smart contracts during planning to assist the team in making informed decisions that lead to a reliable flow. Enabling a reliable construction workflow requires timely identification and removal of constraints under dynamic construction scenarios (Javanmardi et al, 2020). Koskela (1999) identified that at least seven types of constraints must be removed during the planning stage: design and working method, components and materials, laborers, equipment and tools, space, prerequisite work, and external conditions.…”

Application of Information Theory in Last Planner® System for Work Plan Reliability

“…Thus prioritizing the constraints before the weekly meetings can result in improved workflow reliability. Javanmardi et al (2020) used information theory to quantify the effect of weekly meetings on just the PPC of the project using a limited number of constraints. The Information theory is a mathematical representation of the transmission and processing of information through communication (Shannon 1948).…”

“…The proposed model proved to be useful as a basis for a decision support system for planners to evaluate the reliability of their planned production rates. Javanmardi et al (2020) identified the lack of research to quantify constraint removal discussions and how they affect the work plan reliability. They used information theory to identify the information gain and its transmission efficiency to identify its effect on the work plan reliability.…”
