In order to understand this topic‚ continuous-time system comes into different classifications which are the following: * Linear and Nonlinear Systems A system is linear if it follows the superposition principle. Also‚ it satisfies the additivity and homogeneity properties. Hence‚ if a system does not satisfy either of the two properties‚ it is said to be a non-linear system. * Time-varying and Time-Invariant Systems A system is said to be

Q1.(a) What is linear programming problem? (b) A toy company manufactures two types of dolls‚ a basic version doll-A and a deluxe version doll-B. Each doll of type B takes twice as long to produce as one of type A‚ and the company would have time to make maximum of 1000 per day. The supply of plastic is sufficient to produce 1000 dolls per day (both A & B combined). The deluxe version requires a fancy dress for which there are only 500 per day available. If the company makes a profit of Rs 3.00

Specific assumptions were made which will be discussed in detail‚ along with the impact of non-typical days. A sensitivity analysis will then be performed to determine how the percentage of part time employees’ constraint affects the total cost per day.
