Problem 5 Shelves Unlimited is interested in estimating the additional machine center capacities for a new Book Shelf. The shelf is made from two end panels, three shelves plus a number of various fasteners and hangers. Fabrication is as follows: End Panel: Shelf: Operation Machine Run Time (per unit) 123 LN3+ 1 2 3 Operation Machine 1 2 3 Saw Planer 2 minutes Router 4 Saw Molder Router Sander 5 minutes 3 minutes Run Time (per unit) 2 minutes 3 minutes 4 minutes 1 minute Setup Time Per Operation .8 hours .1 hours .8 hours Setup Time Per Operation .3 hours 1.2 hours .7 hours .1 hours A. If Shelves Unlimited makes a batch of 250 Book Shelves (complete units, e.g. sides and side panels), how much time will be required on the Router? B. If it takes 34 hours of molding machine time to complete a batch of 250 Book Shelves (complete units, e.g. sides and side panels), what would be the efficiency of the moulding operation?

Answer the two connected questions (Task A-1 and A-2). Provided in the last part are the guides and examples: The process for large-scale manufacture of paper has been largely unchanged for the last 125 years. The pulp and paper industry today is highly capital intensive, and there is an ongoing drive towards process integration, thereby increasing the efficiency of utilization of available process resources. This paper deals with the Kraft process (see Fig. 1) though the general principles described can be extended to other pulping processes. As shown in Figure 1, five water sinks and four water sources are considered for in-plant water reuse/ recycle. Prior to water reuse/ recycle, the network requires a freshwater flow rate of 36,400 tonne/day and generates 37,186 tonne/day of wastewater (sum of the individual sink and source flow rates in Table 1). The freshwater source that is available for service has an impurity concentration (chloride content) of 4.2 ppm, which is higher than…

Use Cross Product (or Dot Product). Show full solutions.
An order for 100 of a product is processed on work centers A and B. The setup time on A is 30 minutes, and run time is 10 minutes per piece. The setup time on B is 50 minutes, and the run time is 5 minutes per piece. Wait time between the two operations is 4 hours. The move time between A and B is 10 minutes. Wait time after operation B is 4 hours, and the move time into stores is 15 minutes. There is no queue at either workstation. If it is decided to overlap operations A and B by splitting the lot of 100 into two lots of 70 and 30. Wait time between A and B and between B and stores is eliminated. Setup on operation B can start before the first batch arrives. Calculate the manufacturing lead time for the whole order. Calculate the manufacturing lead time for the first patch.

Number of manufacturing processes are listed below. Each manufacturing process has some technological capabilities. Anticipate the best technological capability per each manufacturing process: Turning: Commonly used materials: ( metals, plastics, non-ferrous metals, composite materials, semiconductors). Process variations: ( can be automated, can not be automated, potential for linking with CAD very high). Typical applications: ( any component with rotational symmetrical elements, fillet corners and chamfer edges where possible to increase tool life, pressure vessels, I - section beams, engine blocks).
