Assume that you are the manager of Assembly, Inc. You have just received an order for 26 units of an industrial robot, which is to be delivered at the start of week 7 of your schedule. Using the following information, determine how many units of subassembly G to order and the timing of those orders, given that subassembly G must be ordered in multiples of 80 units and all other components are ordered lot-for-lot. Assume that the components are used only for this particular robot.
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.

| Item | Lead Time (weeks) | On Hand | Components | |
| Robot | 2 | 10 | B, G, C(3) | |
| B | 1 | 5 | E, F | |
| C | 1 | 20 | G(2), H | |
| E | 2 | 4 | — | |
| F | 3 | 8 | — | |
| G | 2 | 15 | — | |
| H | 1 | 10 | — | |
| Subassembly G order quantity (in units) | |
| Subassembly G should start at beginning of Week |
We need 26 units of robots. As 10 units are available , we'd like to create 26-10 = 16 more robots
For 16 robots, we directly need 16 units of G. additionally , we'd like 16*3 = 48 units of C. There are 20 units of C available . Hence we'd like additional 48-20 = 28 units of C. As each unit of C needs 2 units of G, we'd like 28*2 = 56 units of G to create required units of G. Hence the gross requirement of G is 16+56 = 72 units of G. As there are 15 units of G available , the entire units of G to be ordered is 72 - 15 = 57 units of G.
Hence Subassembly G order quantity (in units) = 57 units.
