Summary Introduction
To find:The number of models that should be produced on a daily basis.
Introduction:Companies can produce different models of a product at a time. In this type of production, companies need to set batches for doing production in an economical way. The method in which schedules are prepared for the production of mixed models is known as mixed-model

Your boss at Xiangling Hu Products, Inc., has just provided you with the schedule and lead times for the bracket. The unit is to be prepared in week 10. The lead times for the components a re bracket (I week), base (1 week), spring ( I week), clamp (I week), housing (2 weeks), handle (I week), casting (3 weeks), bearing (I week), and shaft (1 week).a) Prepare the time-phased product structure for the bracket.b) In what week do you need to start the castings?
Francis Johnson's plant needs to design an efficient assembly line to make a new product. The assembly line needs to produce 15
units per hour, and there is room for only five workstations. The tasks and the order in which they must be performed are shown in th
following table. Tasks cannot be split, and it would be too expensive to duplicate any task.

- Natura has to fill 7 orders for its clients. He requires placing the required product in work boxes and subsequently closing them properly so that the product reaches the customer correctly. The process consists of filling the box and later closing it. As the content of each box and the size of these is different, the filling and closing times of each order is different. These times are shown in the table below.

CKC can makeand sell up to the limit of its demand per week; no penaltiesare incurred for not being able to meet all the demand. Eachworkstation is staffed by a worker who is dedicated to workon that workstation alone, and is paid $6 per hour. Totallabor costs per week are fixed. Variable overhead costs are$3,500/week.
