sum student ID =20

1. Answer the following questions: a) List five types of problems that industrial engineers face at the manufacturing/service industries (No explanation is required). b) Any type of the system is typically characterized by various inputs interacting within the system, outputs, transformation processes, and feedbacks. Analyze one of the following systems based on your Student ID! State at least 4 inputs and 3 outputs for the system you are analyzing! Sum of the Student *** The system should be chosen based on System ID numbers the summation of the numbers in Student ranging between ID. For instance, if a student ID number is 118203001, the sum of numbers in the Student Airline Transportation ID is "16"[(1+1+8+2+0+3+0+0+1)]. In this system 0-21 case, the student should determine the inputs Healthcare system 22+ and outputs for an airline transportation system. (Hint: For a manufacturing system, natural resources, labor, energy, capital, tools and equipments are examples of system inputs while the outputs are final products, by-products and scrap.)
