Question

Briefly describe How we get the Mean transport value?

A semi-automated flexible manufacturing cell (FMC) is used to produce three products The products are made by two automated processing stations followed by an assembly station. There is also a load/unload station. Material handling between stations in the FMC is accomplished by mechanized carts that move tote bins containing the particular components to be processed and then assembled into a given product. The carts transfer tote bins between stations. In this way the carts are kept busy while the tote bins are queued in front of the workstations. Each tote bin remains with the product throughout processing and assembly. The details of the FMC can be summarized as shown in Table Q4.1: Table Q4.1 Station Description Number of servers Load and unload2 human workers Process X 1 automated server Process Y 4Assembl 1 automated server 2 human workers Transport Number of carriers to be determined The product mix fractions and station processing times for the parts are presented in the Table Q4.2. The same station sequence is followed by all products: 1->2-3->4->1.

(b) At full capacity, what are the overall production rate of the system and the rate for each product? (c)Determine the minimum number of carts in the material handling system required to keep up with the production workstations. (d) Compute the utilization for each station
