List several of the major differences between manufacturing and service operations and then articulate the importance of a strong manufacturing base to the overall economy.
Manufacturing starts from designing a part and producing it. So it includes all the things such as Raw material, R and D, logistics.
Service operation does not provide any tangible objects. They are basically doing service such as Barber, police etc.
The importance of strong manufacturing is that the country is self-sufficient in manufacturing the products and technology is highly developed. This decreases the imports and increases the export which is good for economy
Describe the objectives of aggregate (production) planning and the relationship between the aggregate plan and the master production schedule.
Aggregate planning in manufacturing is planning so that you allocate the right amount of resources for every process of the manufacturing so that time will be minimized when in IDLE mode. For services, aggregate planning serves to schedule your employees and it varies as to what particular season you are in.
Moreover aggregate planning for services (as oppose to manufacturing) implies: 1. Most services cannot be inventoried 2. Demand for services is difficult to predict 3. Capacity is also difficult to predict 4. Service capacity must be provided at the appropriate place and time 5. Labor is usually the most constraining resource for services
Explain the logic behind how MRP’s gross-to-net calculations are processed. What input files are included in this process?
The suggested planned orders for the end assembly are offset by the lead time, one period, and passed down to the component during the planning process. The gross requirements and the safety stock level represent the total demand. The scheduled receipts and quantity on hand represent the total supply. The net requirements, total demand.
