In each of the following, name the term defined or answer the question. Answers are listed at the bottom.1. Three terms commonly used to refer to a layout where similar equipment or functions are grouped together.2. A layout where the work to make an item is arranged in progressive steps and work is moved between thesteps at fixed intervals of time.3. A measure used to evaluate a work center layout.4. This is a way to shorten the cycle time for an assembly line that has a task time that is longer than the desired cycle time. Assume that it is not possible to speed up the task, split the task, use over time, or redesign the task.5. This involves scheduling several different models of a product to be produced over a given day or week on the same line in a cyclical fashion.
