A local toy manufacturer is using a production line that runs 8 hours per day and produces a toy that requires a total of 7 tasks to be performed. The daily demand is 100 toys. Times of the tasks are 2.73, 2.01, 2.13, 2.0, 2.61, 2.71, and 2.95 minutes for A, B, C, D, E, F, and G, respectively. However, due to the nature of the product there are precedence rules that must be observed. Such that Task A does not need any predecessors; task B requires task A to be completed. To start task C and task D, each require task B to be completed. Task C must be completed prior to stating task E. Task F needs both task D and task E to be completed. Finally, task G can start only once task F is completed.

Hi! I need a little help with D. I can't figure out how to calculate the efficiency. Can you explain it to me?
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 four workstations. The tasks and the order in which they must be performed are shown in the following table. Tasks cannot be split, and it would be too expensive to duplicate any task. TASK TASK TIME (MINUTES) IMMEDIATE PREDECESSOR A 1 — B 2 — C 3 — D 1 A, B, C E 3 C F 2 E G 3 E What is the workstation cycle time required to produce 15 units per hour? Note: Round your answer to 1 decimal place. Balance the line to use the fewest possible workstations to meet the cycle time found in part (b). Use whatever method you feel is appropriate. What is the efficiency of your line balance, assuming the line operates at the cycle time from part (b)? Note: Round your answer to 1 decimal place.

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…

A robbery has just been committed at the Corner Market in the downtown area of the city (black rectangle in the city map). The market owner was able to activate the alarm, and the robber fled on foot. Police officers arrived a few minutes later and asked the owner, "How long ago did the robber leave?" "He left only a few minutes ago," the store owner responded. "He's probably ten blocks away by now", one of the officers said to the other. "Not likely," said the store owner. "He was so stoned on drugs that I bet even if he run ten blocks, he's still only within a few blocks of here! He's probably just running in circles!"Perform a simulation experiment that will test the store owner's hypothesis. Assume that at each corner of a city block there is an equal chance that the robber will go in any one of the four possible directions, north, south, east or west. Simulate for ten steps and five trials, and then indicate in how many of the trials the robber is within three blocks of the store.
