Performance measurement is an important component of lean-based management systems, however cost management systems or analysis have largely been applied at a high level and have not attempted to measure or model the production cost impacts of disruption on a lean project. While it is important to develop systems for practical site management, it is equally important to ensure that such systems...

Material A 106 Gr. B termasuk dalam material seamless carbon steel pipe, dan sering digunakan untuk high-temperature service. Penelitian ini pemodelan menggunakan pipa B, 4 inch, sch 80 dengan panjang 150 mm. Proses pengelasan yang adalah GTAW SMAW. Untuk menemukan proses las parameter paling efektif pada setiap layer flowline, membandingkan variasi kuat arus listrik terhadap hasil uji sifat me...

This paper presents the application of recycled tubular, flowline, and umbilical in coastal protection structures. Flowline tubular are found to improve load resistance capacity concrete beams. Embedment umbilical, into beams would be beneficial structural performance, which do not noticeably alter initial cracking strength beam but will provide good post-cracking resistance. A techno-economic ...

Although drumlins and other subglacial bedforms are well-studied features, controls on their formation and morphometry have remained elusive. Of current interest is the hypothesis that elongate bedforms (length:width ratios]/10) indicate fast ice flow, and perhaps the location of past ice streams. This hypothesis is explored by analysing drumlins from the New York State drumlin field. A subset ...

Englacial and basal temperature data for the Greenland ice sheet (GrIS) are sparse and mostly limited to deep interior sites and ice streams, providing an incomplete representation of the thermal state of ice within the ablation zone. Here we present 11 temperature profiles at five sites along a 34 km east–west transect of West Greenland. These profiles depict ice temperatures along a flowline ...

A suitable initial point for understanding multiphase flows is a phenomenological description of the mechanism geometric distributions or flow patterns that are observed. The challenge however prediction combination operating conditions and characteristics phases as well points transition from one pattern to other. Different occur in different pipeline configurations which U-shape risers part. ...

This paper addresses to the permutation flowline manufacturing cell with sequence dependent family setup times problem. The objective is to minimize the makespan criterion. We propose a cooperative approach including a genetic algorithm and a branch and bound procedure. The latter is probabilistically integrated in the genetic algorithm in order to enhance the current solution. Moreover, the ap...
