A shoe assembly plant buys leather tops and soles from its suppliers. The leather tops have no color on them when bought. The assembly plant first dies the leather with colors like black, beige, brown and cream. Then it sews the colored leather tops to the soles. Finally leather tops are polished with an agent that depends on the color of the shoe. Basically there are three operations in the shoe plant: Coloring, Sewing and Polishing. The activity times and set up times for these operations are given in minutes as follows: Operation Coloring Sewing Polishing Activity time 0.25 0.20 0.15 Set up time 30 20 45 Soles and the leather top-sole assemblies are processed in batches in all operations. The batch sizes are kept the same at all operations. Before a batch goes through an operation, the shoe plant must set up the machines for that operation. a) How many leather tops can be colored in an hour with a batch size of 40? b) Explain why sewing cannot be the bottleneck operation under any batch size. c) For which batch sizes is coloring the bottleneck operation? Here your answer can be an interval of batch sizes rather than a single number because there are many batch sizes which make coloring the bottleneck
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.
