Mixed-model scheduling is a technique that produces different models of the same product family in the same production line or work center. One of the benefits of mixed-model scheduling is that it reduces the number of setups required, as the models share common components and processes. Fewer setups can lead to lower setup costs, higher productivity, and better utilization of resources. The other outcomes are not benefits of mixed-model scheduling. Increased inventory, improved demand response, and fewer material shortages are more related to other factors such as inventory policies, demandforecasting, and supply planning. References: Mixed Model Scheduling | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

Creating short-term wins is a useful element in the change process because it helps to build momentum, motivate the team, and overcome resistance. Short-term wins are concrete achievements that demonstrate the benefits of the change and provide evidence that the efforts are paying off. They also help to create a sense of urgency and alignment among the stakeholders involved in the change process. Calculating a break-even point, performing a SWOT analysis, and developing key performance indicators (KPIs) are all important tools for planning and evaluating the change process, but they are not as effective as creating short-term wins in generating support and commitment for the change. References: Change Management: The Kotter Model, APICS CPIM 8 Planning and Inventory Management | ASCM

Mixed-model scheduling is a technique that allows multiple products to be produced on the same assembly line without changeovers, and then sequences those products in a way that smoothes the demand for upstream components12. In this case, the company is using mixed-model scheduling to produce three different products (A, B, and C) on the same line, and then alternating them in a pattern that minimizes the variation in the workload and the inventory levels. The other options are not correct because:

•Matrix scheduling is a technique that assigns tasks to workers based on their skills and availability3.

•Synchronized scheduling is a technique that coordinates the production and delivery of materials and components to match the demand of the final assembly4.

•Line balancing is a technique that distributes the workload evenly among the workers or machines on a production line5.

The primary outcome of frequent replenishments in a distribution requirements planning (DRP) system is that the level of required safety stock is reduced. Safety stock is the extra inventory that is held to protect against demand uncertainty or supply variability. Frequent replenishments mean that the inventory is replenished more often and in smaller quantities, which reduces the risk of stockouts and the need for safety stock. Frequent replenishments also improve the inventory visibility and accuracy, which enable better demand forecasting and inventory planning. By reducing the safety stock, the company can lower its inventory carrying costs, free up working capital, and increase its inventory turnover. The other options are not correct, as they are not the primary outcome of frequent replenishments, but rather possible benefits or drawbacks of frequent replenishments, depending on the situation:

• Lead times to customers decrease: This may or may not be true, depending on the distance between the distribution centers and the customers, the transportation mode and frequency, and the customer service level. Frequent replenishments may reduce the lead times if the distribution centers are closer to the customers and the transportation is fast and reliable. However, frequent replenishments may also increase the lead times if the distribution centers are far from the customers and the transportation is slow and infrequent.
• Transportation costs decrease: This may or may not be true, depending on the transportation mode, distance, and volume. Frequent replenishments may reduce the transportation costs if the transportation mode is economical, the distance is short, and the volume is high. However, frequent replenishments may also increase the transportation costs if the transportation mode is expensive, the distance is long, and the volume is low.
• More efficient load consolidation occurs: This is unlikely to be true, as frequent replenishments usually mean smaller shipments that are less likely to fill the capacity of the transportation vehicles. Load consolidation is the process of combining multiple shipments into one larger shipment to optimize the transportation efficiency and reduce the transportation costs. Frequent replenishments may reduce the opportunities for load consolidation and increase the transportation inefficiency and costs. References:
