Given in the following table are the tasks necessary for final assembly of a hospital bed, the length of time needed to perform each task, and the operations that must be completed prior to subsequent operations. Construct a precedence diagram and balance the assembly line for a desired cycle time of 14 minutes. Draw a schematic diagram of the balanced line. How many beds can actually be assembled in an eight-hour period? Element Precedence Time (min) A None 4 B None 5 C None 8 D A 4 E A, B 3 F B 3 G D, E 5 H F 7 I G, H 1 J I 7 K C, J 4
SITUATION: A company is about to begin production of a new product. The manager of the department that will produce one of the components for the product wants to know how often the machine used to produce the item will be available for other work. The machine will produce the item at a rate of 200 units a day. Eighty units will be used daily in assembling the final product. Assembly will take place five days a week, 50 weeks a year. The manager estimates that it will take almost a full day to get the machine ready for a production run, at the cost of $300. Inventory holding costs will be $10 a year. QUESTION: Suppose the manager decides to increase the run size of the new product. How many additional units would be needed just to accommodate the other job? How much will that increase the total annual cost?
Management wants to design an assembly line that will turn out 800 videotapes per day. There will be eight working hours in each day. The industrial engineering staff has assembled the information below: A) Determine the maximum and minimum cycle times.B) Determine the optimum cycle time.C) What is the minimum number of stations needed?D) Draw the precedence diagram.E) Assign tasks to stations in order of most following tasks first. Submit an Excel file based on Chapter 6 Excel Template to indicate your computation.

A dress-making operation is being designed as an assemblyline. Table 10-22 shows the tasks that need to be performed, theirtask times, and preceding tasks. If the goal is to produce 30 dressesper hour, answer the questions that follow the table. (a) Compute the cycle time.(b) Which task is the bottleneck?(c) What is the maximum output for this line?(d) Compute the theoretical minimum number of stations.(e) Assign work elements to stations, using the longest tasktime rule.(f) Compute the effi ciency and balance delay of yourassignment.
A production process at Kenneth Day Manufacturing is shown in Figure S7.9. The drilling operation occurs separately from, and simultaneously with, sawing and sanding, which are independent and sequential operations. A product needs to go through only one of the three assembly operations (the operations are in parallel).a) Which operation is the bottleneck?b) What is the bottleneck time?c) What is the throughput time of the overall system?d) If the firm operates 8 hours per day, 20 days per month, whatis the monthly capacity of the manufacturing process?

The City Commission of Nashville has decided to build a botanical garden and picnic area in the heart of the city for the recreation of its citizens. The precedence table for all the activities required to construct this area successfully is as follows: Code Description A BCDEFGH G I Find location; determine resource requirements Requisition of lumber and sand Dig and grade Saw lumber into appropriate sizes Position lumber in correct locations Nail lumber together Put sand in and under the equipment Put dirt around the equipment Put grass all over the garden, landscape, paint Time (hrs) 20 60 100 35 20 10 20 30 Immediate Predecessor(s) None A A B D, C E F F- G, H Refer to the legend for the activity that corresponds to each code. Using the line drawing tool, draw a Gantt chart for activities E through I of the project.
Draw a sequence diagram on this scenario. Consider an e commerce website, the customer will search for the items either by category, by price, by color or by size. the customer will add the selected items to the shopping cart. He/she can either continue shopping or can perform checkout. On checkout bill/invoice will be generated and the customer will enter personal information including email, phone and address; will choose cash on delivery option or card payment. If card payment selected, he/she will enter the card information. The bank object will validate the card, if validated the required amount will be deducted and the item will be dispatched to the provided address in both cases (COD/ valid card payment).
