A small electronic company assembles power supplies for use in bread maker, cake mixer and food processor. It wants to set up an assembly line to make its operations more efficient and plan to use line balancing with the incremental utilization heuristic. The demand for power supplies is 200 per hour, and the productive time per hour is 52 minutes. The following table provides details on its operation (with time in minutes): Tasks that must Time to perform task 0.56 0.34 immediately precede Task A B C A 0.11 0.09 0.43 0.22 0.62 0.35 0.21 A A B,C E F G E F,G H J 0.57 K 1,J 0.33 (a) Compute the cycle time.

Breakeven Analysis
Break Even Analysis is a term used in business, cost accounting and economics. It refers to a point where the total cost incurred becomes equal to the total revenue earned. Break Even Analysis determines the number of units to be sold to earn the revenue required to cover the total costs. Total cost is a sum total of fixed and variable costs.
Process analysis
The term process analysis can be defined as breakdown of production process into different phases that converts inputs into output. A series of routine activities are incorporated using organizational resources with a view to achieve operational excellence.
