Determine: a) The cycle time in minutes; b) the minimum number of workstations for this contract; c) Balance of lines by the corresponding heuristic.
Critical Path Method
The critical path is the longest succession of tasks that has to be successfully completed to conclude a project entirely. The tasks involved in the sequence are called critical activities, as any task getting delayed will result in the whole project getting delayed. To determine the time duration of a project, the critical path has to be identified. The critical path method or CPM is used by project managers to evaluate the least amount of time required to finish each task with the least amount of delay.
Cost Analysis
The entire idea of cost of production or definition of production cost is applied corresponding or we can say that it is related to investment or money cost. Money cost or investment refers to any money expenditure which the firm or supplier or producer undertakes in purchasing or hiring factor of production or factor services.
Inventory Management
Inventory management is the process or system of handling all the goods that an organization owns. In simpler terms, inventory management deals with how a company orders, stores, and uses its goods.
Project Management
Project Management is all about management and optimum utilization of the resources in the best possible manner to develop the software as per the requirement of the client. Here the Project refers to the development of software to meet the end objective of the client by providing the required product or service within a specified Period of time and ensuring high quality. This can be done by managing all the available resources. In short, it can be defined as an application of knowledge, skills, tools, and techniques to meet the objective of the Project. It is the duty of a Project Manager to achieve the objective of the Project as per the specifications given by the client.
A methods analyst at Integrated Products Corporation (IPC) has been studying the line of
assembly that produces optical readers for barcodes. The goal of the analysis is to reduce the
idle time of workers on the assembly line to lower cost per labor
of optical readers. This information is applicable:
| TASK | Precedents | Time (min) |
| A. Form the purchased assemblies into kits | - | 1.35 |
| B. Inspect kit assemblies | A | 2.20 |
| C. Process the control board in the auto-insertion equipment line | - | 1.90 |
| D. Process controller card in welding equipment line | C | 2.39 |
| E. Trim and finish control board. | D | 1.75 |
| F. Assemble power unit to frame. | B | 1.25 |
| G. Assemble the reader unit to the frame. | F | 0.90 |
| H. Assemble control board to frame. | E, G | 2.49 |
| I. Assemble the Deployment Unit to the Rack | H | 2.19 |
| J. Inspect and test the finished optical reader | I | 2.40 |
| K. Pack the finished optical reader. | J | 0.69 |
20 optical barcode readers are to be produced on the production line per hour. In
average, they are only productive 50 minutes per hour, due to staff time, breakdowns
of machinery and start and stop times. Since the union contract restricts the types of
task that can be combined into workstations, tasks can only be grouped within
these compatibility sets:
| Compatibility Group | TASK |
| GROUP 1 | A, B |
| GROUP 2 | C |
| GROUP 3 | D |
| GROUP 4 | E |
| GROUP 5 | F,G,H,I,J,K |
For example, tasks F and G could be combined on a workstation, but tasks E and F could not.
Tasks within compatibility groups can be combined while still fulfilling
with precedence relationships. In other words, you can combine adjacent tasks along
length of the network diagram. Group I work is essentially manual, requiring only
many inexpensive tools.
Determine: a) The cycle time in minutes; b) the minimum number of workstations for this
contract; c) Balance of lines by the corresponding heuristic.
