How would you characterize the most important difference for the following issues when comparing a workcenter (job shop) and an assembly line?

a. The number of changeovers: In a workcenter more changeovers are needed to achieve more product variety. An assembly line has fewer changeovers as product variety will require a new setup. Changeovers are adjustments of machine settings as one moves from one product to the other, and during this process, production is halted.

b. Labor content of product:As an assembly line is more automated than a workcenter, higher labor skills are required in a workcenter compared to an assembly line. The products from the workcenter will naturally have higher labor content, and those from the assembly line will have lower labor content.

c.Flexibility:Workcenters offer more flexibility than assembly lines. The product variety is greater in workcenters, i.e., they offer differentiated products at any point, but the assembly line does not offer the same. As mentioned above, changeovers are less likely in assembly lines, so flexibility is less seen in assembly lines and more in workcenters.
