How to explain the cost performance of the crusher

PostgreSQL: Documentation: 9.4: Using EXPLAIN

14.1. Using EXPLAIN. PostgreSQL devises a query plan for each query it receives. Choosing the right plan to match the query structure and the properties of the data is absolutely critical for good performance, so the system includes a complex planner that tries to choose good plans. You can use the EXPLAIN command to see what query plan the planner creates for any query.

COST AND PRICE ANALYSIS--AN EXPLANATION

Cost Analysis is the element-by-element examination of the estimated or actual cost of contract performance to determine the probable cost to the vendor. The goal is to form an opinion on whether the proposed costs are in line with what reasonably economical and efficient performance should cost.

Crusher Efficiency Calculations

 · For the 1-in. screen below the roll crusher the capacity has no correction factor and the area needed is 32/2.1 = 15.2 sq ft. To handle the output from a 40 x 24 roll crusher the screen will have to be at least 24 in. wide. Perhaps it will be more effective to use one continuous screen of at least 20.1 + 15.2 = 35.3 sq ft.

7.1 The Costs of Turnover – Human Resource Management

In HR, we can separate the costs associated with turnover into indirect costs and direct costs. Direct turnover costs include the cost of leaving, replacement costs, and transition costs, while indirect turnover costs include the loss of production and reduced performance. The following are some examples of turnover costs (Maertz & Campion, 1998):

Crusher

A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
