Q3 (a) Explain the objective of scheduling. (2 marks) Differentiate between finite and infinite loading. (4 marks) You are managing a furniture restoration company and have four tasks to be completed through a two-step processes. The first process involves sanding and the second involves polishing. The time for processing each job is shown in Table Q3. Table Q3: Time Processing for each task Polishing (Hours) 1.7 Task C13 C81 DS D44 Sanding (Hours) 2.5 3.8 1.9 1.8 2.6 1.0 3.0 Calculate the optimal sequence for these tasks to be scheduled. (5 marks) Illustrate these tasks through the two-step processes. (5 marks) (iii) Determine the total length of time of this optimal solution. (2 marks) (iv) Determine idle time for both processes.
