@@The_Business_Doctor hello Dr. Mark, Could you please suggest me book for assembly line design and balancing of it.Total from scratch to final optimal line.
@@maheshpatil2017 Hi Manesh. Basically any operations management textbook with a chapter dedicated to assembly line balancing would do the trick. If you're in Canada, I can recommend a couple books. Where are you located?
@@The_Business_Doctor india. Actually I am expecting designing of line and procedure to do it. For example. I want to assemble few gearboxes of different sizes which need same operations to be performed on it but each gearbox size has different processing time. i.e.multi model.
@@maheshpatil2017 I would recommend this book: www.mheducation.com/highered/product/operations-management-stevenson/M9781260238891.html It includes a great chapter on the basics of assembly line balancing and then you can adapt to the complexity of your needs.
Based on the textbooks I have used, cycle time is "the maximum time allowed at each workstation to complete its set of tasks on a unit." (Stevenson & Hojati, 2011; Heizer, Render, Munson, & Griffin, 2020). This problem gives us tasks which have yet to be organized into workstations and the cycle time represents the maximum amount of time that a unit can spend in a workstation in a given cycle. The total sum of all the tasks (process if you like) to complete a product is the task duration time and we divide the duration time by the cycle time to determine the optimal number of workstations. So in this case, if the task duration time (in seconds for an entire hour) is 3600 seconds to produce a unit through all the tasks and the cycle time is a maximum of 20 seconds per unit, that means we need to try to organize the tasks into 3 workstations to allow the unit to be produced. It could be that different textbooks and sources may interpret the cycle time slightly differently. Here was have a WORKSTATION cycle time of 20 seconds per unit and a total (ideal) PRODUCTION cycle time of 60 seconds (which is what I think you're trying to get at). However, sometimes the theoretical number of workstations cannot be achieved because of the precedence relationships and times of the tasks, so you might need 4 workstations. In this case the actual PRODUCTION cycle time would be greater than the WORKSTATION cycle time. I guess it depends on the source you're referring to.
