Problem 6E

The article “Earthmoving Productivity Estimation Using Linear Regression Techniques” (S. Smith, Journal of Construction Engineering and Management, 1999:133-141) presents the following linear model to predict earthmoving productivity (in m3 moved per hour): where x1 = number of trucks,

x2 = number of buckets per load,

x3 = bucket volume, in m3,

x4 = haul length, in m

x6 = truck travel time, in s,

a. If the bucket volume increases by 1 m3, while other independent variables are unchanged, can you determine the change in the predicted productivity? If so, determine it. If not, state what other information you would need to determine it.

b. If the haul length increases by 1 m, can you determine the change in the predicted productivity? If so, determine it. If not, state what other information you would need to determine it.

23 August 2016 Social change: a change in the system of social relationships Social movements: can be informal or formal. Almost always focused on a speciﬁc social/political issue Stages: emerge —> coalesce —> bureaucratise —> success, failure, cooptation, repression, go mainstream —> decline Development: develop countries to have strong economic structure. Neo-liberalization and globalization impact development. Economic well- being through industrialization, agriculture industrialization, etc. Globalization: trade with other countries. Idea that through increased trade and through technology there is more interconnectedness — smaller world. Major driver for social change, driven by technology. 30 August 2016

The answer to “The article “Earthmoving Productivity Estimation Using Linear Regression Techniques” (S. Smith, Journal of Construction Engineering and Management, 1999:133-141) presents the following linear model to predict earthmoving productivity (in m3 moved per hour): where x1 = number of trucks,x2 = number of buckets per load,x3 = bucket volume, in m3, x4 = haul length, in mx5 = match factor (ratio of hauling capacity to loading capacity),x6 = truck travel time, in s,a. If the bucket volume increases by 1 m3, while other independent variables are unchanged, can you determine the change in the predicted productivity? If so, determine it. If not, state what other information you would need to determine it.________________b. If the haul length increases by 1 m, can you determine the change in the predicted productivity? If so, determine it. If not, state what other information you would need to determine it.” is broken down into a number of easy to follow steps, and 143 words.
