PROBLEM

 

        1.     Hinge Manufacturing Company employs a Kanban system for a component part. The daily demand is 900 hinges. Each container has a wait time of 0.05/day, and a processing time of 0.37 days. The Container size is 60 hinges and the safety factor (a) is 10%.

        2.     A manufacturer of automobile engines is designing a new Kanban system for engine #321. The demand for #321 is 75/day and they are built in groups of 8. The total process and wait time is 3 days. The manager wants an alpha (a) of 2 or 200%. How many Kanbans are required?

3.      A company is using Kanban containers. There are two adjacent work centers, a downstream (using) and an upstream (producing) one. The using work center has a production rate of 200 parts per day and each container holds 20 parts. It takes .5 days for a container to make the entire cycle from the time it leaves the upstream center until it is returned, filled with production, and leaves again. The manager wants a safety factor (a) of 20%.  The company is interested in reducing the number of containers.

4.      A company is using a Kanban system with 2 containers, each holding 50 parts, between a downstream (using) and an upstream (producing) work center. The using work center can handle 250 jobs per day. The average elapsed time for the entire cycle is currently .25 days. The company is concerned with the safety factor for the operation and the size of the containers.

5.      A manufacturing company is using a two-container Kanban system between a downstream (using) and an upstream (producing) work center. Each container holds 25 parts. The using work center can handle 100 parts per day. The average elapsed time for the entire cycle is currently .40 days. The company is concerned about the efficiency of the operation.

TRUE/FALSE

 

        1.     Because the preparation of annual reports is done on a repeating basis, project management techniques are not appropriate.

        2.     Project management objectives revolved around on-time and budget performance.

        3.     A statement of work would be developed in the "Organize" step of the project life cycle.

        4.     Project managers need to be specialists, not generalists.

        5.     In most organizations, projects cut across organizational boundaries, making it difficult to implement projects exclusively within functional departments.

Which one of the following statements is true?

2.     A project has three paths. A-B-C has a length of 25 days. A-D-C has a length of 15 days. Finally, A-E-C has a length of 20 days. Which one of the following statements is true?

3.     Which of the following is not considered a project?
