Consider a process that consists of three workstations: The first workstation (WS 1) takes 20 minutes per unit, the second workstation (WS 2) takes 10 minutes, and the third workstation (WS 3) takes 15 minutes per unit. Each workstation is staffed by one worker.

(a) What is the net processing time per unit?

(b) What is the cycle time per unit?

(c) What is the utilization of the process?

(d) How many units of output can be produced a day, if the process runs an 8-hour shift a day?

Expert Solution

a) Net processing time per unit =Time at first workstation + Tim at second workstation + Time at thrd workstation

= 20 + 10 + 15 minutes = 45 minutes

b) Cycle tiem per unit will be decided by th bottleneck operation requiring maximum time. Therefore, cycle time per unit = 20 minutes

c) Utilization of the process = Total duration of all activities / ( number of workstations x cycle time ) x 100

= ( 20 + 10 + 15) / ( 3 x 20) x 100

= 45/60 x 100

= 75%

d) Outputs that can be produced in 8 hour shift = 480 minutes/cycle time 20 minutes = 24 units

A part arrives every ten minutes to a system having three workstations (A, B, and C), where each workstation has a single machine; the first part arrives at time 0. There are four part types, each with equal probability of arriving. The process plans for the four part types are given below. The entries for the process times are the parameters for a triangular distribution (in minutes). Part Type workstation/ Process Time workstation/ Process Time workstation/ Process Time Part 1...

A production process consists of a three-step operation. The scrap rate is 20 percent for the first step and 12 percent for the other two steps. a.If the desired daily output is 461 units, how many units must be started to allow for loss due to scrap? (Do not round intermediate calculations. Round up your final answer to the next whole number.) Number of units = b.If the scrap rate for each step could be cut in half at every...

The rental process for these cues is exhaustive and takes 75 minutes for each application. There are three employees that conduct these interviews, and on average, it is one hour between customer arrivals. What is the arrival rate? What is the service rate? On average, how many hours do customers wait to begin the application process? What is the probability all servers are idle?

Consider a single server queueing system. Arrivals take place every four minutes (first arrival takes place at t=0). Service times are random and take the value of 1 with probability 1/2 and 5 with probability ½. Assume that the following service time sequence is generated: S1=5, S2=5, S3=5, S4=1, S5=5. Simulate for T=20 minutes and estimate the average number of customers in the system and the average waiting time of a customer.

The commercial for the new Meat Man Barbecue claims that it takes 20 minutes for assembly. A consumer advocate thinks that the assembly time is lower than 20 minutes. The advocate surveyed 11 randomly selected people who purchased the Meat Man Barbecue and found that their average time was 19.7 minutes. The standard deviation for this survey group was 2.1 minutes. What can be concluded at the the αα = 0.05 level of significance level of significance? For this study,...

A manual process takes 18 minutes of direct labor time and six pounds of material to produce a product. Automating the process requires 12 minutes of machine time and 5 pounds of material. The cost per labor hour is $9, the cost per machine hour is $7, and the cost per pound of materials is $11. Find the nonvalue - added cost for the above situation. $2.40 per unit $12.30 per unit $9.00 per unit $1.70 per unit

1. Alice has 2 jobs that she will process sequentially. The first job takes an exponential amount of time with a mean of 15 minutes. Once the first job is completed, then we start working on the second job. The second job also takes an exponential amount of time to complete with a mean of 15 minutes. (a) Let T be the total time to complete both jobs. Give the distribution of T, its mean and its standard deviation. (b)...

Activity Three: Poisson and Exponential Distributions An accountant notes that, on average, it takes 30 minutes to talk to two clients, with the time of visits following an exponential distribution. What is the probability that the time between the arrival of one client to the arrival of the next client will be less than ten minutes? Can you show the same answer using the Poisson formula by asking the probability that at least one client will be seen within a...

A random experiment consists of throwing a triangular shape with three faces three times. The first face has the number 1, the second face has the number 2 and the third face has the letter A. List the sample space of the random experiment. Assume the faces are equally likely, what is the probability an outcome of experiment has at least one A? the letter A is three times likely to occur in a throw than the...
