Name and describe the different states that a process can exist in at any given time. (Max of 5 lines)
Heizer and Render advises that when analyzing and designing processes to transform resources into goods, the followingquestions should be asked:- Is the process designed to achieve competitive advantage in terms of differentiation, response or low cost?- Does the process eliminate steps that do not add value?- Does the process maximize customer value as perceived by the customer?- Will the process win orders?A Time-Function Map is similar to a flow process chart, but with time added to the horizontal axis. With time-function mapping,notes indicate the activities and arrows indicate the flow direction, with time on the horizontal axis.

- 3.Consider the following three-stage production process of glass ceramics. The process is experiencing severe quality problems related to insufficiently trained workers. Specifically, 20 percent of the parts going through operation 1 are badly processed by the operator. Rather than scrapping the unit, it is moved to a highly skilled rework operator, who can correct the mistake and finish up the unit completely within 15 minutes. The same problem occurs at station 2, where 10 percent of the parts are badly processed, requiring 10 minutes of rework. Station 3 also has a 10 percent ratio of badly processed parts, each of them requiring 5 minutes by the rework operator. a)What is the utilization of station 2 if work is released into the process at a rate of 5 units per hour? b)Where in the process is the bottleneck? Why? (Remember, the bottleneck is the resource with the lowest capacity, independent of demand.)arrow_forwardA two station nurses clinic operates where you must visit the first station before the second.

What would the new coefficient of variation be if the standard deviation of the second nurse station is reduced by 60%?arrow_forwardA process is replicated in another country where wages are 50 percent lower. Staffing and processing times are identical. What would be the effect on the costs of directlabor?a. Costs of direct labor would be 50 percent lower.b. Costs of direct labor would be the same.c. Costs of direct labor would be 50 percent higher.d. Cannot determine from the given information.arrow_forward
- 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.

Move time to add and remove them from the oven is neglig bile, it takes 32 minutes to bake cakes - the bakery has two ovens, each able to hold 2 cakes. The one pastry chef on staff puts on an amazing show that draws a crowd all day-each cake is decorated in 6 minutes. The bakery operates 8 hours per day. Answer each of the following questions: a. What is the cycle time (in minutes per cake) of each stage - preparing, baking, and decorating? b. What is the dally process capacity? Explain. c. If orders arrive at a rate of 3 cakes every 20 minutes, can the bakery meet the caily demand Explain, Note: Be clear about how you…arrow_forward
