Exаm Questiоn — AnyLоgic AGV Order-Fulfilment Mоdel (10 mаrks) Figure: Screenshot of а running AnyLogic model using the Material Handling Library. Study the flowchart statistics (numbers entering/leaving each block, numbers currently inside) and the robotFleet resource pool indicator, then answer the following. (a) [2 marks] State how many agents (orders) have been generated by Source and how many have exited at orderComplete. Using these, calculate the total work-in-process (WIP) currently in the system. (b) [2 marks] The robotFleet pool displays 99% and 0/3. Explain precisely what each of these two indicators means, and state the fleet's capacity. (c) [3 marks] Identify the bottleneck of this system. Justify your answer using at least two pieces of quantitative evidence from the figure, and explain why orders accumulate in goToProduct (333 waiting) rather than in the delay blocks. (d) [1 mark] productItem shows 150 in / 150 out with 0 agents inside, while parcelItem shows 51 in / 50 out with 1 inside. What does this tell you about the service capacity of the two delay blocks relative to their arrival rates? (e) [2 marks] Propose two distinct design changes that would improve throughput, and predict the effect of each on robot utilisation and on the queue at goToProduct. (One change must not involve buying more robots.)
