We are analyzing the performance of four different machines, all subjected to the same workload. We have calculated the average Cycle Time (CT) and Work in Progress (WIP) for these machines. Which machine has the smallest effective variability? Machine 1: CT= 5 hours , WIP= 15 units Machine 2: CT= 10 hours , WIP= 30 units Machine 3: CT= 20 hours , WIP= 60 units Machine 4: CT= 40 hours , WIP= 120 units

local market research fim has just won a contract for several thousand small projects involving data gathering and statistical analysis. In the past, the firm has assigned each project to a single member of its highly trained professional staff. This person would both gather and analyze the data Using this approach, an experienced person can complete an average of 10 such projects in an eight-hour day. The firm's management is thinking of assigning two people to each project in order to allow them to specialize and become more efficient The process would require the data gatherer to fill out a matrix on the computer, check it and transmit it to the statistical analysis program for the analyst to complete. Data can be gathered on one project while the analysis is being completed on another, but the analysis must be complete before the statistical analysis program can accept the new data. After some practice, the new process can be completed with a standard time of 20 minutes…
For the production of part R-193, two operations are being considered. The capital investment associated with each operation is identical. Operation 1 produces 2,100 parts per hour. After each hour, the tooling must be adjusted by the machine operator. This adjustment takes 15 minutes. The machine operator for Operation 1 is paid $24 per hour (this includes fringe benefits). Operation 2 produces 2,350 parts per hour, but the tooling needs to be adjusted by the operator only once every two hours. This adjustment takes 45 minutes. The machine operator for Operation 2 is paid $13 per hour (this includes fringe benefits). Assume an 8-hour workday. Further assume that all parts produced can be sold for $0.35 each. a. Should Operation 1 or Operation 2 be recommended? b. What is the basic tradeoff in this problem?
A process has seven elements composed of combination of worker and machine. Elements A, B, D, and F are worker-controlled while elements C and E are machine controlled. Element G is a worker-controlled irregular element performed every five cycles Machines are idle during elements A, D, and G. Two units are produced every cycle. Below are the observed time (in minutes) and performance rating of each element. Work Element Observed Time (in minutes) Performance Rating A 0.75 115% B 1.20 120% C 1.40 N.A. D 1.05 90% E 1.25 N.A.

A company assembles a product that consists of three pieces called AA, BB, and CC. The AA and BB parts are manufactured by the company itself, while the CC parts are purchased from another manufacturer. The process times, in hours, required for each piece in each of the processes are given in the following table: Process 1 Process 2 Process 3 Process 4 Process 5 AA 1 0.5 0.5 BB 1.5 0.5 0.5 0.5 The company has 20 machines that can carry out process 1, 5 process 2, 10 process 3, 5 process 4 and 5 process 5. Each machine works a maximum of five days each week at a rate of fifty weeks a year , in working days of 8 hours a day. Formulate and solve to determine the maximum number of assembled sets that you can produce.

Hello! I need help with this Little's Law question in my homework: Strohrmann, a large-scale bakery in Pennsylvania, is laying out a new production process for their packaged bread, which they sell to several grocery chains. It takes 12 minutes to bake the bread. How many loaves of bread must be baked per minute to produce 4,000 loaves of bread per hour? (Round the answer to 2 decimal places.) How large an oven is required so that the company is able to produce 4,000 loaves of bread per hour, as measured in terms of the number of units that can be baked simultaneously? (Round your answer to the nearest whole number.)
Create a swim-lane process map for placing and receiving an order at a fast food restaurant. Please choose a restaurant where you can see the food being prepared (e.g Panera Bread, McDonalds, Arbys, Subway, Taco Bell, etc.). > Your process map will have three swim-lanes: you, cashier (taking your order), and cook (preparing food). You do not need to include any metrics (times, distances, etc.).
