Collect statistics on the crane utilization, the average inventory cost, the average number of each part type in the warehouse, and the number of unfilled requests due to having no parts of the requested type.

HINTS: Use index variables for part inventory and per-part cost. (Note that you can use the Other option in the Assign module when assigning to index variables.) Use the Discrete distribution to determine the part type and the Statistic data module to collect some of the required statistics.

Problem Statement (Ex.5-10 in the book, page 266) A small warehouse provides work in-process storage for a manufacturing facility that produces four different part types. The part type percentages and inventory costs per part are Inventory Cos Part Type Percentage Per Part 20 30 30 20 $5.50 $6.50 $8.00 S10.50 4 The interpretation of inventory cost per part" is as follows. Each part in inventory contributes an amount from the last column of the above table to the total cost (value) of inventory being held at the moment. For instance, if the current inventory is three units of Part 1, none of Part 2, five of Part 3, and one of Part 4, then the curren t ?nventory cost is 3 $5.50 + 0 >
