Project management: a quality management approach
Excellent publications have been available on project management for many years and much discussion has taken place extolling the virtues of this aspect of management and its great influence on the overall successful operation of organizations in all sectors. When being considered in its generic form, project management can also be applied to any set of activities, and in this context it is no less than a universal management tool. This paper examines the feasibility and practicality of applying a quality management approach to project management. The model used for the analysis is the criteria of the Canada Awards for Excellence, the internationally recognized quality award program.
A multi-objective approach for decision making during the project life cycle
This paper is concerned with the multi-objective nature of projects and proposes a comprehensive methodology for the decision making process during the project life cycle. We address a situation in which several decisions are considered, where each may affect the major project objectives: time, cost and scope. The objectives are formally defined and a multi-objective, mixed-integer, linear-programming formulation for the decision selection is developed. We then provide the decision maker with a set of non-dominated alternatives, each associated with a subset of the feasible decisions.
Experimental study on bond behavior between high-strength grout and deformed steel bars
Abstract Engineers use high-strength grout to connect precast concrete members for its low shrinkage and good fluidity. This paper designed 87 central pull-out specimens using the control variable method to investigate the influence of factors on the rebar-grout bond property such as compressive strength, steel grade, bar diameter, transverse stirrups, and bond length. The test result showed that improving grout compressive strength (85.8 MPa–122.7 MPa) cannot improve the bond strength, which was different from the previous conclusions of concrete pull-out tests. Simplified formulas were presented for calculating the characteristic values of bond strength, residual strength, peak slip, and relative slip of load-holding platform based on parameter analysis. Then, a constitutive model was proposed to predict the full-range bond stress-slip curve of high-strength grout and steel bar specimens from bearing to failure. Finally, FEA models were established to evaluate the applicability and accuracy of the constitutive model.
