This paper presents a model for strategically locating drop-lots on a supply chain distribution network. The problem is modelled as a set covering location problem with the addition of a set of minimum-distance-away constraints. The effect of these constraints on the solution space is dramatic, reducing the problem size significantly. It is also proposed that the use of drop-lots in a supply chain can have beneficial quality of life effects for the truck drivers in such a system by allowing them more home time. A real-life example problem from the Midwest is used to validate the model and some computational experience is also reported.

2D Resistivity Imaging for Locating Concrete Pipe - Case Study
Background There are 8 wells that suply water to the communnity through about 2m diamter concrete aqueduct. Purpose The main subject of the field tes was to determine the geotechnical site characterization of the area to correlate the results obtained through the 2D resistivity imaging and the infromation of the concrete aqueduct. Process The determination of site characterization was performed by AGI SuperSting Wi-Fi R8/IP/SP instrument with 42 electrodes and 3 meters electrode spacing with a mixed array...
Locating Groundwater Wells for Fracking Operations in West Texas - Case Study
In June 2014, our clients used AGI resistivity imaging tools to successfully locate a 125-gallon-per-minute groundwater well in West Texas as well as geohazards that could, if left unlocated, cause significant damage to property and increase costs. Process Our clients used the SuperSting R8 Wi-Fi with a SwitchBox 112, passive cables spaced at six meters apart, and a dipole-dipole and strong gradient array. To model the data, they enlisted the help of the EarthImager 2D with a finite element inversion model....
NEC Classifications and Divisions for Hazardous Locations
Electrical equipment in hazardous (classified) locations present a serious threat for workers due to the existence of explosive dust and vapors. Examples of such facilities range from grain mills and gasoline stations to aircraft hangars and chemical manufacturing plants. To prevent devastating explosions that may occur from the ignition of combustible particles in the atmosphere, the National Electric Code (NEC) published guidelines on the proper classification of hazardous locations. Classes, Divisions and...
