Factors for Computing Control Chart Limits (3 sigma)

LOADING…

for this problem.

Twelve samples, each containing five parts, were taken from a process that produces steel rods at Emmanual Kodzi’s factory. The length of each rod in the samples was determined. The results were tabulated and sample means and ranges were computed. The results were:

For the given data, the

x double overbarx

=

nothing

inches (round your response to four decimal places).

Based on the sampling done,

the

control limits for 3-sigma

x overbarx

chart are:

Upper Control Limit

(UCL Subscript x overbarUCLx )

=

nothing

inches (round your response to four decimal places).

Lower Control Limit

(LCL Subscript x overbarLCLx )

=

nothing

inches (round your response to four decimal places).

Based on the

x overbarx -chart,

is one or more samples beyond the control limits?

?

Yes

No

.

For the given data, the

Upper R overbarR

=

nothing

inches (round your response to four decimal places).

The control limits for the

3-sigma

R-chart are:

Upper Control Limit

(UCL Subscript Upper RUCLR )

=

nothing

inches (round your response to four decimal places).

Lower Control Limit

(LCL Subscript Upper RLCLR )

=

nothing

inches (round your response to four decimal places).

Based on the R-chart, is one or more samples beyond the control limits?

?

Yes

No

he candy machine outside the lecture hall sees a steady stream of customers throughout the day. The service time is governed by a negative exponential probability distribution that averages 10 seconds. Over the course of a day, students arrive for candy at the rate of 240 per hour — Poisson distributed 1. Write down the service rate and arrival rate.

2. Calculate the following:

• How many students are waiting in front of the machine?

• How long does a student wait to be served with candy from the machine?

• What is the probability that the candy machine will be idle and a student will not have to wait?

In this project, you will be exposed to the data collection and data analysis technique as well as to propose and design a solution to a particular problem domain. In the business process improvement/reengineering concept, you are required to understand the current business requirements, problems, procedures and any other related matters that affected the business process under your investigation. For example: • What is this business process is all about? • What are the sub business processes involved? • Why this process is executed in this manner? • What are the procedures? • Who is in-charge (PIC)? • What are the problems/issues in this process? • How can IT helps? Etc. After the data collection process, you have to perform data analysis. Based on your analysis, you are required to produce a report that consists of a business improvement plan that includes the BPI/BPR processes, as well as the proposed design and specification to represent the problem solution. The problem solution/outcomes may also address the potential improvements that can be done with the process and this including highlights any management or technical issue, opportunity, or constraint, procedure, etc., if any. 2

List of Tasks (Please READ and FOLLOW the instructions given below)

1. Choose one business unit in UNITEN or a small company of your choice. Contact the business unit or the company either through a virtual meeting, email or telephone and seek for their permission to study one of their business processes for this subject IT and BPR. You may refer to the description above.

2. Prepare a set of interview questions, form (if required) to be used for your data collection purposes.

3. Set an appointment with the business unit/company representatives for the interview session. You will have a maximum of 2 weeks to complete your data collection process.

4. Conduct data analysis.

5. Verify your finding with the respective business unit (the officer in charged).

6. Write a project report and present your finding in class.

1.0 PROBLEM DEFINITION AND PROJECT OVERVIEW

1.Describe the business unit/company, the business process under study and it’s gaps/issues

2.0 THE BUSINESS PROCESS

• DESCRIBE THE PROCESS, you followed in investigating, analyzing, and redesigning the business process. Example, you may want to include a description about users, how did you obtain feedbacks from the users and how did you incorporate that feedback into your system redesign? What is the data collection technique used? Why? • Model the current system (using Flow-chart or Process Flow Diagram) • How did you evaluate the system/process and identify GAPS/ISSUES for this company? • Evaluation of the gaps/issues

3.0 THE PROPOSED BUSINESS PROCESS IMPROVEMENT

• Discuss your proposed SOLUTIONS for the gaps/issues. Examples: Describe the flow of activities that appropriate to your system /process and to your level of knowledge. Example, what data does your system need? What are the sources of data? How are data represented? • Model your solutions: you may provide a diagram that shows how the business process can be improved. You may also include a set of proposed procedure to be followed. You can also propose a system for this company.

4.0 CONCLUSION

Write a conclusion of your project. What did you learn?

Please, only experienced professionals should do it. I will give a down vote if you don’t know it and do nonsense for me.
