Simply put, a system is a dynamic, purposeful collection of components. Information and materials flow among these components. A system has boundaries; that which is outside the boundaries is considered the system's environment. Generally, the environment is considered to be outside the system's control; open systems are affected by their environment, whereas closed systems are not. Feedback loops provide

14. Briefly discuss THREE (3) functions of inventory management 15. If 100 units of X are needed in week 10, develop a planning schedule showing when 3 each item should be ordered and in what quantity (using template as below) X LT : 1 5 6 8 9 Y LT : 2 10 Z LT : 3 A LT : 4 B LT : 5 C LT : 6 *LT: Lead Time 16. Product X is made of two units of Y and three units of Z. Y is made of one unit of A and two units of B. Z is made of two units of A and four units of C. Lead time for X is one week; Y is two weeks; Z is three weeks; A is two weeks; B is one weeks; and C is three weeks. Draw a product structure to show the material requirement planning for product X. 17. Outline FIVE (5) roles of project manager. 18. Define inventory management 19. Ray's Satellite Emporium wishes to determine the best order size its best-selling plate, model TS111. Ray has estimated the annual demand for this model at 1,000 units. His cost to carry one unit is RM1.25 per unit per year and he has estimated that each order cost RM5 to place. Ray's Satellite Emporium operates business 365 days per year and finds that deliveries from his dealer generally take 5 working days. i. What is the economic order quantity (EOQ)? iL. How many orders would he made each year? ill. What is the time between order? iv. Based on the case above explain to Ray how to minimize the cost. V. Based on the case above explain to Ray how to minimize the cost. 20. Define Material Requirement Planning (MRP) and identify FOUR (4) benefits of it. 21. Analyse TWO (2) components of Material Requirement Planning. 22. The following is a list of components required to produce one unit of end item P: P: 2 A's, 3 B's, 3 C's A: 5 M's, 2 R's B: 1 D, 3 N's C: 1 T, 4 N's M: 1N Determine the number of N's that will be needed to make 60 P's in each of these cases: i. Draw product structure tree. ii. There are currently 10 P's on hand. 23. State any FIVE (5) Deming's 14 Points for implementing quality improvement.
