A contractor is planning the acquisition of construction equipment, including bulldozers, needed for a new project in a remote area. Suppose that from his prior experience with similar bulldozers, he estimated that there is a 65% chance that each bulldozer can remain operational for at least 6 months. 1.) If he purchased four bulldozers for the new project, what is the probability that there will be at least two bulldozers left operational after six months into the project?.

Pricing Construction Equipment

Pricing construction equipment means estimating the cost of operation of all the construction equipment used in a construction project. The pricing is done based on two factors – ownership cost and operating cost of the equipment. Thorough knowledge of the ownership and operating costs is necessary for proper project management and executing profitable construction.

A Highway contractor has four locations A, B, C, and D on a road contract which crushed stone is to be delivered. The stone, which is all of the same quality is to be supplied from three quarries 1, 2, and 3. The table below shows the relative transportation cost per cubic meter of transporting stone from each quarry to each site. However, the contractor discovered a technical problem in the third quarry, which results in a temporary shutdown of the facility. Based on this new condition, the contractor must deliver the crushed stone from the first and the second quarries only. Any shortage in the required crushed stone has to be covered from an external source. a) What is the optimal allocation of the crushed stone from each quarry to each location under the new circumstances? b) What is the transportation cost corresponding to the solution obtained in part a? c) Which of the four sites are affected by the shortage that results from the shutdown of the third quarry?
