A Critical Path Problem Using Triangular Neutrosophic Number, Florentin Smarandache, Mai Mohamed, Yongquan Zhou, Mohamed Abdel-Baset

Branch Mathematics and Statistics Faculty and Staff Publications

The Critical Path Method (CPM) is one of several related techniques for planning and managing of complicated projects in real world applications. In many situations, the data obtained for decision makers are only approximate, which gives rise of neutrosophic critical path problem. In this paper, the proposed method has been made to find the critical path in network diagram, whose activity time uncertain. The vague parameters in the network are represented by triangular neutrosophic numbers, instead of crisp numbers. At the end of paper, two illustrative examples are provided to validate the proposed approach.

Optimum Injury And Illness Prevention Cost For U.S. Construction Projects, Sathyanarayanan Rajendran, Morgan Bliss, Dominic Klyve

Mathematics Faculty Scholarship

Worker injuries and illnesses can affect the profitability of an organization. Regardless of the regulatory requirements for safety and health, many organizations prefer to see positive returns (i.e., better safety metric performance) on their safety investments (i.e., project costs associated with injury and illness prevention programs). Understanding the relationship between costs associated with an injury and illness prevention program of a construction project and project safety performance is critical to the future success of construction organizations in the United States. In evaluating this relationship, the authors’ goal was to identify an equilibrium point of injury and illness prevention program investment …

The Differences Between Cpm And Resource-Loaded Scheduling And How They Applied To The Martinez Tesoro Refinery Flare Header Replacement Project, Connor Steven Carone

Construction Management

A case study was conducted to analyze the scheduling challenges faced on a refinery construction project in Martinez, California. The main issues on the project were complications experienced by the general contractor in fulfilling a requirement to produce a resource-loaded schedule. Unable to create one, a CPM schedule was produced instead. Research on the differences between a CPM and resource-loaded schedule was conducted in order to uncover how they applied to the refinery project. The most significant differences between the two scheduling methodologies is that a CPM assumes infinite capacity, while resource loading recognizes that resources have finite limits in …

Shrinkage Cracking In Concrete Tilt-Up Construction, Stewart Hooks, Jack Robinson

Architectural Engineering

The purpose of this project is to investigate a particular, undesirable cracking pattern in concrete tilt-up panels that, until now, did not have a known definite cause. The cause of this cracking pattern is hypothesized to be due to shrinkage restraint of the concrete panels. The cracking under investigation occurs at the bottom corners of the Tilt-Up panels, suggesting that the base of the panel is restrained from shrinkage. This project models various components of Tilt-Up Construction that have potential for restraining the panels from shrinking. This project consists of the following main components.

The first aspect of this project …
