Tutorial $4$: Resource Utilization

An aircraft component manufacturing and assembly company utilizes mainly $4$ types of aircraft structural components. The manufacturing shop comprises of $6$ work centres which are used to manufacture the components and there is an infinite supply of raw materials for these machines to produce the components. Assembly is done as per order, and it takes $12$ min to complete. The objective is to find the status of resources in $8$ hours shift and the utilization of resources. Also comment on optimization of the floor

The production material flow diagram is given below.

Once the parts are assembled a Forklift is used to transfer parts from the order assembly area with a processing time of $12$ min to storage. The processing time of the machines is given below. The order arrival table for each orders is given below,
