assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
Fatigue strength evaluation of self-piercing riveted cold rolled steel joints under mixed mode loading conditions
Fatigue strength of cross-shaped specimens of SPR joints made of SPCC was evaluated at load angles of 0°, 45°, and 90°. For the static strength at load angles of 0°, 45°, and 90°, the maximum loads were determined to be 4890N, 1969N, and 1611N, respectively. Regarding for the relationship between the load amplitude and the number of cycles (Nf), the results were 014 . 0 3 . 2209 − = f amp N P ,...

متن کاملRecent development in finite element analysis of self-piercing riveted joints
Self-piercing riveting (SPR) is a high-speed mechanical fastening technique which is suitable for point-joining advanced lightweight sheet materials that are dissimilar, coated, and hard to weld. Major advances have been made in recent years in SPR technique. Latest literature relating to finite element analysis (FEA) of SPR joints is reviewed in this paper. The recent development in FEA of SPR...
متن کاملProject Risk Analytic Assessment Using the Hierarchy Process
Often, construction projects fail to achieve their time, budget, and quality goals. This is frequently due to the failure of the contractor to analyze and assess unanticipated risks. The analytic hierarchy process (AHP) is a new approach that can be used to analyze and assess project risks during the bidding stage of a construction project and to overcome the limitations of the traditional appr...
