Transportation cost and delivery time are two of the trade-offs that should be evaluated when determining where to place inventory in a multi-echelon supply chain network. A multi-echelon supply chain network consists of multiple levels of distribution, such as factories, warehouses, distribution centers, and retailers. Placing inventory closer to the customers can reduce the delivery time and improve the service level, but it can also increase the transportation cost and the inventory holding cost. Placing inventory farther from the customers can reduce the transportation cost and the inventory holding cost, but it can also increase the delivery time and the risk of stockouts. Therefore, the optimal inventory placement depends on balancing these trade-offs and finding the lowest total cost for the desired service level. The other trade-offs are not directly related to inventory placement in a multi-echelon supply chain network. Production cost and lot size quantity are more related to inventory replenishment policies and economies of scale. Purchase cost and shrinkage rates are more related to inventory sourcing and quality control. Customer price and order quantity are more related to demand management and pricing strategies. References: Network Design and Safety Stock Placement for a Multi-Echelon Supply Chain, APICS CPIM 8 Planning and Inventory Management | ASCM

Time series decomposition is a method that breaks down a time series of historical demand data into its components: trend, seasonality, cyclical, and random. It is appropriate for forecasting the demand for a product family when there is a significant trend and seasonality in the demand history, as it can isolate and estimate these components and project them into the future. Time series decomposition can also handle cyclical and random variations in demand, and it can be applied to different time intervals (such as monthly, quarterly, or yearly). The other methods are not suitable for this scenario. Econometric models are complex mathematical models that use regression analysis to relate demand to various explanatory variables, such as price, income, or advertising. They are not designed to capture trend and seasonality in demand. Computer simulation is a technique that uses a computer program to mimic the behavior of a real system under different scenarios and assumptions. It is not a forecasting method per se, but rather a tool for testing and evaluating different forecasting methods or policies. Weighted moving average is a simple method that uses the average of the most recent observations as the forecast for the next period, with more weight given to the recent observations than the older ones. It is not able to capture trend and seasonality in demand, as it assumes that demand is stable and does not change over time. References: Time Series Decomposition | APICS Dictionary Term of the Day, APICS CPIM 8 Planning and Inventory Management | ASCM

One way to mitigate liability risk in the supply chain is to require traceability for components. Liability risk is the risk that a party may be held responsible for certain types of losses caused by its actions or products to third parties1. Traceability is the ability to track the origin, history, location, and movement of a product or a component through the supply chain2. Requiring traceability for components can help to mitigate liability risk in the supply chain by enabling the identification and verification of the quality, safety, and compliance of the components, as well as the detection and prevention of counterfeit, defective, or hazardous components. Traceability can also facilitate the recall, repair, or replacement of faulty components, and the allocation of responsibility and accountability among the supply chain partners in case of a liability claim34.

Risk pooling reduces inventory variability by aggregating demand across multiple locations or products. This strategy lowers safety stock requirements while maintaining service levels. It is widely used in inventory planning to counter variability due to uncertain demand patterns across the supply chain.

“Risk pooling is most effective in reducing inventory and managing variability because demand uncertainties across regions can offset each other when aggregated.”

A Fourth-Party Logistics (4PL) provider assumes broader roles than a traditional third-party logistics (3PL) provider. It is not only responsible for the physical movement of goods but also for managing the supply chain as a whole, including coordination between the client and multiple logistics service providers.

“Companies that not only take on the responsibility of the physical movement of goods between a supplier and a customer but also take more of the supply chain service requirements are called a fourth-party logistics company.”

Developing flexible operations best supports a company’s strategic focus on delivery speed to improve competitive advantage. Delivery speed is the time it takes for a company to deliver its products or services to the customers after receiving an order. Delivery speed is a key factor in customer satisfaction, retention, and loyalty, as well as a source of differentiation and value creation in the market1. Developing flexible operations means having the ability to adapt to changes in demand, supply, technology, and environment, and to respond quickly and efficiently to customer needs and expectations. Flexible operations can improve delivery speed by reducing lead times, increasing responsiveness, enhancing quality, and minimizing costs23.

A reduction in purchased lot sizes means ordering smaller quantities of materials more frequently. This reduces the average inventory level and the carrying cost of inventory. However, it also increases the frequency of orders and the ordering cost. The reorder point (ROP) is the level of inventory that triggers a new order, and it depends on the demand rate, the lead time, and the safety stock. The ROP is not affected by the lot size, unless the demand or the lead time changes. The setup time is the time required to prepare a machine or a process for production, and it is not related to the purchased lot size. References: EXAM CONTENT MANUAL PREVIEW, page 14, section 6.1.2. Manufacturing Planning and Control for Supply Chain Management: The CPIM Reference, Second Edition, page 433, section 12.4.

Process engineers are responsible for designing, implementing, controlling, and optimizing industrial processes, especially continuous ones such as the production of petrochemicals1. One of the decisions that process engineers would most likely make is the routing sequence, which is the order of operations or activities that are performed on a product or material as it moves through the production process2. The routing sequence affects the process performance, efficiency, quality, and cost, and it requires careful planning and analysis by the process engineers. Option A is not correct, because lead times are the time intervals between the initiation and completion of a process or a project3. Lead times are influenced by many factors, such as demand, capacity, inventory, scheduling, and supply chain management, and they are not solely determined by the process engineers. Option B is not correct, because production capacity is the maximum amount of output that a process or a system can produce within a given period of time4. Production capacity depends on the availability and utilization of resources, such as materials, labor, equipment, and facilities, and it is not only decided by the process engineers. Option C is not correct, because product reliability is the probability that a product will perform its intended function without failure for a specified period of time under specified conditions5. Product reliability is affected by many aspects, such as product design, quality control, testing, maintenance, and customer feedback, and it is not the sole responsibility of the process engineers.
